Anatomy Lab Exam 2 Review

The correct answer is tibialis anterior, as the muscle commonly referred to as #21 is the tibialis anterior located in the front of the lower leg.

The correct answer, extensor hallucis longus, is a muscle located in the lower leg responsible for extending the big toe. The incorrect answers provided are unrelated muscles located in different parts of the body.

Tendons #29 are specifically attached to the extensor digitorum longus muscle, which is responsible for extending the fingers and toes.

Vessel A refers to the right common iliac artery which is a blood vessel that carries oxygenated blood to the right lower limb.

Vessel B refers to the inferior vena cava, which is a large vein in the human body responsible for carrying deoxygenated blood from the lower body to the heart. The aorta, pulmonary artery, and carotid artery are incorrect as they are arteries responsible for carrying oxygenated blood away from the heart to different parts of the body.

Vessel C, known as the left renal vein, is responsible for draining blood from the left kidney into the inferior vena cava. The superior mesenteric vein drains blood from the gastrointestinal tract, the inferior vena cava is a major vein returning deoxygenated blood from the lower body to the heart, and the pulmonary artery carries deoxygenated blood from the heart to the lungs for oxygenation.

In the context of the question, C is described as leaving the kidney, so the correct answer is leaving. The incorrect answers are not supported by the information provided in the question.

The sciatic nerve is the largest nerve in the body and runs from the lower back down the back of each leg. Issues with this nerve can cause sharp pain, numbness, or tingling in the lower back, buttocks, legs, and feet.

The correct answer is 'tibial' as it refers to the shinbone, specifically the larger and stronger of the two bones in the lower leg. The other options do not correspond to the shinbone.

The correct nerve to the lateral leg is the common fibular nerve, whereas the femoral, tibial, and sciatic nerves do not specifically supply the lateral leg region.

The vertebral arteries are the vessels that feed the posterior brain and travel via the cervical vertebrae. The carotid arteries supply blood to the anterior portion of the brain, the jugular veins drain blood from the head and neck, and the pulmonary arteries carry deoxygenated blood from the heart to the lungs.

The left common carotid artery is responsible for supplying blood to the face and anterior brain. The incorrect options do not serve this specific function.

The right subclavian artery is the correct answer as it is an important blood vessel that supplies blood to the right arm and the right side of the head and neck. The other options are incorrect as they are not specific to the right side of the body.

The right common carotid artery is one of the two main arteries that supplies oxygenated blood to the head and neck.

The brachiocephalic artery is also known as the innominate artery. It is the major artery that supplies blood to the right arm and the head and neck.

The correct answer is the left common carotid artery, which is an important artery that supplies oxygenated blood to the head and neck. The right common carotid artery is located on the right side. The subclavian artery supplies blood to the arms and chest. The brachial artery is the major blood vessel that runs down the upper arm.

The left subclavian artery is the third branch of the aortic arch, providing blood supply to the left arm. The brachiocephalic artery is the first branch of the aortic arch, the inferior vena cava is a large vein carrying deoxygenated blood to the heart, and the common iliac artery supplies blood to the lower limbs.

The superior mesenteric artery is a major blood vessel in the abdomen that supplies blood to the small intestine. The incorrect answers are other blood vessels but do not accurately match the description of a red vessel.

The correct answer is inferior mesenteric artery because it is a major blood vessel in the abdominal area that supplies blood to the large intestine.

The subscapularis is the rotator cuff muscle located in the anterior scapula region and provides support to the anterior shoulder.

The muscles of the medial thigh primarily adduct the thigh, bringing it closer to the midline of the body. Abduction would move the thigh away from the midline, while flexion and extension refer to movements at the joints.

The primary action of hamstring muscles at the knee is flexion, which involves bending the knee joint.

The popliteal artery is located behind the knee, connecting the femoral artery to the tibial arteries, while the femoral artery is located in the thigh, the brachial artery is in the arm, and carotid artery is in the neck.

The posterior tibial artery is a major artery of the lower leg, responsible for supplying blood to the calf and sole of the foot. The other options listed are major arteries located in different regions of the body.

Artery C specifically refers to the anterior tibial artery, which is a major blood vessel in the lower leg. The other options provided are different arteries located in various parts of the body.

The fibular artery is also known as the peroneal artery and is a branch of the posterior tibial artery in the lower leg.

B refers to a specific muscle in the human body, the correct answer is the flexor digitorum longus. This muscle is responsible for flexing the toes at the ankle joint. The incorrect answers are muscles that perform different functions in the body.

In this question, C refers to the flexor hallucis longus muscle. The other options are different muscles that are not synonymous with C.

The right brachiocephalic vein is the main vein responsible for draining the upper right side of the body, including the right arm and head. It is an important vessel in the venous system.
