Bài Tập Trắc Nghiệm GIải pHẫu Chi Trên

The correct answer is "Cơ Delta". The question asks about the location of the arrow on the diagram, and the arrow is pointing to the "Cơ Delta" muscle.

Based on the drawing, the cut is shown above the elbow joint, indicating that it is located on the upper third of the arm. Therefore, the correct answer is "1/3 trên cánh tay" which translates to "1/3 above the arm" in English.

The correct answer is "ĐM mũ cánh tay sau." This is because the question is asking about which artery passes through the quadrangular space of the shoulder along with the nerves. The artery that passes through this space is the posterior circumflex humeral artery, which supplies blood to the muscles and tissues of the posterior shoulder and upper arm.

The given answer is incorrect because it states that the "Khuyết quay ở mặt trong mỏm vẹt, khớp với vành xương quay" (The pivot is on the inner side of the trochlea, articulating with the capitulum). However, the correct statement is "Khuyết quay ở mặt ngoài mỏm vẹt, khớp với vành xương quay" (The pivot is on the outer side of the trochlea, articulating with the capitulum).

The correct answer is "Cơ duỗi cổ tay quay ngắn." This is because the other options listed are all muscles involved in wrist extension, while "Cơ duỗi cổ tay quay ngắn" refers to the muscle responsible for wrist supination, which is a different movement.

Both statement (A) and statement (B) are correct, but they are not causally related to each other. Statement (A) states that it is not possible to tighten the belt between the subclavian artery and the brachial artery in front of the shoulder and behind the shoulder. Statement (B) explains that the subclavian artery connects with the axillary artery through the superior and inferior scapular arteries. These two statements are independent of each other and do not have a cause-effect relationship.

The question is asking about the number of sensory nerves. The correct answer is 3, indicating that there are three sensory nerves.

Thần kinh hiển refers to the sensory nerve, which is responsible for transmitting sensory information from the body to the brain. It is the nerve that allows us to perceive and experience sensations such as touch, temperature, pain, and pressure.

When the nerves in the wrist are compressed in carpal tunnel syndrome, it leads to loss of motor function in the muscles of the hand. The action of "Đối ngón cái" (opposing the thumb) requires the use of muscles controlled by the compressed nerves and therefore cannot be performed.

The correct answer is "Duỗi, dạng và xoay đùi". This means that the action of the pelvic-hip muscles is to extend, flex, and rotate the thigh.

The correct answer is "Tk bịt". In Vietnamese, "bịt" means "to cover" or "to block". Therefore, the correct answer suggests that the nerve that controls the muscles of the body is blocked or covered.

In the standing position, the posterior superior iliac spine is located at the same level as the sacroiliac joint and the second sacral vertebra.

The given answer states that (A) is correct and (B) is incorrect. This means that the statement "The sciatic nerve is the largest nerve in the body" is true, while the statement "The sciatic nerve originates from branches of the 4th and 5th lumbar nerves and the 1st and 2nd sacral nerves" is false.

The correct answer is "Tất cả các nhánh thần kinh ở lớp sâu đều là thần kinh vận động." This statement is incorrect because not all branches of the nerve in the deep layer are motor nerves. There are also sensory nerves present in the deep layer of the nerve plexus.

The correct answer is 4, 5 đúng. The first statement states that the button between the hat and the shoulder strap is dangerous when tightened. The second statement states that the sitting position is the largest branch of the tangled TK belt. The third statement is not clear and cannot be explained. The fourth statement states that the trunk strap has a wrist folding mechanism. The fifth statement states that the knee strap is the last branch of the duodenal artery when it descends. Therefore, statements 4 and 5 are correct.

The correct answer is "Củ mu" because the question is asking about which structure the uterine artery is anchored to in the pelvic bone. "Củ mu" refers to the uterine cornu, which is the area where the fallopian tubes attach to the uterus. This is an important detail to consider when studying the pathway of the uterine artery.

The correct answer is "Cơ ngực lớn" because it is the only muscle in the given options that is related to climbing. The term "cơ leo trèo" translates to "climbing muscles" in English, and the pectoralis major muscle, also known as the chest muscle, is responsible for movements such as pulling and pushing, which are essential for climbing. The other muscles listed, such as cơ ngực bé (small chest muscle) and cơ răng trước (front teeth muscle), do not have a direct association with climbing.

The correct answer is "Nền xương đốt bàn III có một mỏm trâm". This means that the third metacarpal bone has a tubercle.

The given answer is incorrect. The correct answer is "Mặt sau là cơ khép dài và cơ khép lớn". This statement is incorrect because the posterior surface of the popliteal fossa is formed by the semimembranosus muscle and the tendon of the biceps femoris muscle, not by the long head of the biceps femoris muscle.

The correct answer is "Chi tiết 13 là cổ xương vai" because the statement is incorrect. "Cổ xương vai" translates to "neck of the shoulder bone" in English, which is not a correct anatomical term. The correct term for the neck of the shoulder bone is "cổ xương cánh tay" or "cổ xương đòn". Therefore, this statement is incorrect.

The correct answer is "Thần kinh mác sâu" because the question asks for the specific nerve indicated by the arrow in the drawing. "Thần kinh mác sâu" is the only option that matches this description. The other options, such as "Thần kinh chày" and "Thần kinh nông," do not accurately represent the nerve indicated in the drawing.

The correct answer is 2,5,6. This is because in the supine position of the hand, the joints involved are the rotating wrist joint (2), the rotating-trapezoid joint (5), and the rotating-trapezoid joint below (6). The shoulder joint (1) and the rotating forearm joint (3) are not involved in this specific hand position.

The given correct answer states that the weakest ligament of the shoulder joint is the middle glenohumeral ligament, and as a result, the shoulder joint is commonly dislocated anteriorly.

The correct answer is "Chi phối cả giác cho một ngón rưỡi bên trong và vận động cho cơ gan tay ngắn." This means that the nerve branch controls both the sensation and movement of a finger on the inside and the short muscles of the hand.

The correct answer is that the anterior wall of the axilla consists of 4 muscles arranged in 2 layers.

The correct answer is "TK ngực dài" because the question is asking which nerve controls the anterior teeth. "TK ngực dài" refers to the long thoracic nerve, which innervates the serratus anterior muscle, responsible for protracting the scapula and assisting in shoulder abduction. It does not directly control the anterior teeth, but it is the closest option related to the question.

The correct answer is "Cơ may, cơ thẳng đùi và cơ thắt lưng chậu." This is because these three muscles are located in the buttock area and work together to provide stability and movement in the hip and pelvic region. The gluteus maximus (cơ may) is the largest muscle in the buttocks and is responsible for hip extension and external rotation. The hamstrings (cơ thẳng đùi) are a group of muscles located at the back of the thigh that help with hip extension and knee flexion. The gluteus medius and minimus (cơ thắt lưng chậu) are smaller muscles that assist with hip abduction and internal rotation.

The correct answer is I, II. This is because the question asks which muscles are innervated by the branches of the nerves responsible for rotation. From the given information, we can see that cơ cánh tay quay (rotator cuff muscles) and cơ duỗi ngón cái dài (extensor pollicis longus muscle) are the muscles involved in rotation. Therefore, the correct answer is I, II.

The statement "Thành trong tam giác đùi là cơ lược và cơ khép ngắn" is incorrect. The correct statement should be "Thành trong tam giác đùi là cơ lược và cơ khép dài."

The correct answer is "Phần trước TK thắt lưng 2,3,4" because the question is asking about the nerves that are blocked. "Phần trước" means "front part" and "TK thắt lưng" refers to the lumbar plexus, which is a network of nerves in the lower back. Therefore, "Phần trước TK thắt lưng 2,3,4" means the nerves in the front part of the lumbar plexus at the levels 2, 3, and 4 are blocked.

The correct answer is IV, V, VII, VIII. These muscles, including the cơ dạng ngón cái dài (IV), cơ duỗi ngón trỏ (V), cơ gấp ngón cái dài (VII), and cơ gấp ngón cái dài (VIII), all become tendons at the 1/3 distance from the elbow. This means that they attach to bones in the forearm and hand, allowing for movement and control of the fingers and thumb.

The statement that is incorrect when talking about the arterial anastomoses in the axillary region is that the anastomoses around the shoulder and chest only partially connect with the anastomoses with the brachial artery, so constricting the axillary artery between the subscapular artery and the deep brachial artery is very dangerous.

The correct answer is not correct because it states that the "Thần kinh nông vùng cẳng chân" includes the branches of the "thần kinh chày" (nerve of the sole). However, the "thần kinh nông vùng cẳng chân" actually includes the branches of the "thần kinh nông" (saphenous nerve) and not the "thần kinh chày".

The correct answer is "Dây chằng đốt bàn tay ngang nông". This is because the question is asking for the term that describes the distinct horizontal lines on the fingers in a hand model. "Dây chằng đốt bàn tay ngang nông" translates to "horizontal lines on the fingers in a hand model" in English, which accurately describes the given phenomenon.

The correct answer is "Cơ khép lớn" because the question is asking which muscle separates the front and back muscles. The "Cơ khép lớn" (also known as the gluteus maximus) is the largest muscle in the body and is located in the buttocks. It separates the front muscles from the back muscles and is responsible for hip extension and external rotation.

The correct answer is the description of the humerus bone. It states that the humerus bone is positioned vertically, with a rounded head pointing upwards and a groove on the anterior side. This aligns with the anatomical features of the humerus bone, making it the correct answer.

The correct answer is "Thần kinh bì cẳng tay trong đi trong ống cánh tay một đoạn ngắn rồi chọc qua mạc nông ở 1/3 dưới cánh tay". This statement is incorrect because the ulnar nerve (thần kinh bì cẳng tay) runs through the groove between the medial epicondyle and the olecranon process of the humerus bone, not through the cubital fossa (mạc nông).

The given information states that the inner part of the vertical arch of the foot is formed by the participation of bones (5), (6), and (7). This means that these three bones contribute to the structure of the inner part of the arch.

The correct answer is 1,2,3 đúng. These muscles are simultaneously controlled by both the spinal cord and the brain. The muscles mentioned in options 1, 2, and 3 (Cơ gấp ngón cái ngắn, Các cơ giun, Cơ gấp chung các ngón sâu) are all controlled by both the peripheral nervous system (spinal cord) and the central nervous system (brain). This dual control allows for precise and coordinated movements of these muscles.

The correct answer is "Cơ đenta" because the arrow is pointing to the location where the muscle originates or attaches.

The correct answer is 2,3,4,6. The question asks which nerve fibers are involved in sensory perception in the foot. The information given lists different nerves, and by examining the options, we can see that nerves 2, 3, 4, and 6 are the ones mentioned. Therefore, these nerves are the ones responsible for sensory perception in the foot.

The correct answer is 6. This means that the hepatic artery in the forearm passes through 6 compartments.

The statement is correct because the hip joint is prone to dislocation when the ligaments surrounding it are not properly supporting it in the resting position during extension and flexion movements.

The correct answer is "Cơ ngực lớn được chi phối bởi quai thần kinh ngực" which means "The major pectoral muscle is controlled by the pectoral nerve". This statement correctly identifies the nerve responsible for controlling the major pectoral muscle, which is the pectoral nerve.

The correct answer is "Gân cơ gấp ngón cái dài". The arrow in the picture is pointing to a fold in the muscle that is long and located near the thumb.

If (A) is false and (B) is true, it means that the statement "Thắt động mạch đồng mạch dễ gây nguy hiểm" is false, while the statement "Vì động mạch đồng mạch cấp máu chính cho vùng đồng mạch" is true. This suggests that there is no causal relationship between the two statements.

The correct answer is "Nhánh bì đùi trước giữa của thần kinh đùi." This is because the question asks which nerve passes through the muscle. The "Nhánh bì đùi trước giữa của thần kinh đùi" is the branch of the femoral nerve that passes through the muscle, making it the correct answer.

The correct answer is "Cơ dạng ngón cái ngắn" because it is the only option that refers to the muscles of the thumb. "Cơ gan tay ngắn" refers to the short muscles of the forearm, "Cơ khép ngón cái" refers to the joint muscles of the thumb, "Cơ gian cốt 1 và 2" refers to the muscles between the first and second metacarpal bones, and "Cơ dạng ngón cái dài" refers to the long muscles of the thumb.
