Feline Muscular Anatomy Quiz

The muscle in question is the sartorius, as it originates at the anterior superior iliac spine and inserts at the tibial medial epicondyle. Rectus femoris, adductor longus, and gracilis do not have the same origin and insertion points as described.

The muscle described which originates from the pubis and inserts into the medial surface of the tibia is the Gracilis. Rectus femoris originates from the ilium, Sartorius originates from the anterior superior iliac spine, and Soleus originates from the head and proximal portion of the fibula.

The brachioradialis muscle originates at the distal humerus and inserts at the styloid process of the radius, allowing for flexion at the elbow joint.

The correct muscle that fits the given origin and insertion points is the Extensor carpi radialis longus. It originates from the lateral epicondyle of the humerus and inserts into metacarpals 2 and 3. The incorrect options do not match the specified origin and insertion points for this muscle.

The correct answer is Flexor carpi radialis as it is the only muscle among the options that matches the given origin and insertion points.

The correct answer, Flexor carpi ulnaris, originates at the medial epicondyle of the humerus and inserts at the proximal end of the 5th metacarpal. Flexor digitorum superficialis, Flexor carpi radialis, and Pronator teres have different origins and insertions.

The Pectoralis Major muscle has a convergent pattern origin at the Clavicle, Sternum, and Costal cartilages with insertion at the proximal end of the Humerus, making it responsible for movements involving the shoulder joint.

The correct answer is Masseter because it is the primary muscle responsible for closing the jaw, with the origin at the zygomatic arch and insertion at the mandible. Temporalis also aids in jaw movement, originating from the temporal bone and inserting on the mandible. Sternocleidomastoid is a neck muscle with origin at the sternum, clavicle, and mastoid process, while Pterygoid muscles are involved in jaw movement and are located within the mouth cavity.

The sternomastoid muscle originates from the manubrium and clavicle and inserts into the mastoid process of the skull. This muscle is responsible for various movements of the head and neck.

The Clavotrapezius muscle originates from the occipital bone, spines of C7, and all T vertebrae and inserts into the spine and acromion of the scapula. It is responsible for movement and stabilization of the scapula.

The correct answer, Latissimus Dorsi, is a large muscle that extends from the lower portion of the back to the arm. It plays a significant role in various movements involving the shoulder and arm.

The muscle described in the question is the Spinodeltoid, as it originates from the clavicle, acromion, and scapular spine, and inserts at the deltoid tuberosity of the humerus. The Trapezius, Pectoralis Major, and Latissimus Dorsi muscles have different origins and insertions compared to the Spinodeltoid.

The correct answer, Spinotrapezius, is a muscle that originates from the occipital bone, spines of C7 and all T vertebrae, and inserts at the spine and acromion of the scapula. Deltoid originates from the clavicle and scapula, Latissimus dorsi originates from the lower back, and Serratus anterior originates from the ribs. Therefore, they are not the correct answers for the given origin and insertion points.

The deltoid muscle is actually known as clavobrachialis in humans, not to be confused with other muscles like biceps brachii, pectoralis major, or trapezius.

The biceps brachii muscle originates from the coracoid process and intertubercular groove of the humerus, and inserts into the radial tuberosity. Its main movements include flexing the arm and forearm, as well as supinating the hand.

The correct answer is the Brachialis muscle because it originates from the distal anterior humerus and inserts into the coronoid process of the ulna. The Biceps brachii and Triceps brachii muscles are also located in the arm but have different origins and insertions. The Flexor carpi ulnaris muscle is located in the forearm and not involved in the specified origin and insertion mentioned in the question.

The external oblique muscle is a paired muscle located on the lateral and anterior parts of the abdominal wall. It helps in flexing the torso, rotating the trunk, and compressing the abdomen.

The correct answer is Triceps brachii as it originates from the axillary border of scapula and posterior humerus, inserts into the olecranon process of the ulna, and functions to extend the forearm and stabilize the shoulder. Biceps brachii, Deltoid, and Brachialis do not match the given origin, insertion, and movement characteristics provided in the question.

The correct answer is Biceps Femoris as it originates from the ischial tuberosity and femur, and inserts at the proximal end of tibia and fibula. The other options have different origins and insertions, making them incorrect for this specific question.

The extensor digitorum longus muscle originates from the posterior tibia, inserts on the distal phalanges of toes 2-5, and is responsible for extending toes 2-5 and dorsiflexing the ankle. Flexor hallucis longus, flexor digitorum longus, and peroneus longus are not involved in the described movements.

The Gastrocnemius muscle is responsible for flexing the lower leg and plantarflexing the foot. It originates from the medial and lateral condyles of the femur and inserts via the Achilles tendon onto the calcaneal tendon.

The correct answer is Gluteus Maximus as it matches the provided origin and insertion points. Quadratus Lumborum originates from the iliac crest and inserts into the 12th rib and lumbar transverse processes. Piriformis originates from the anterior surface of the sacrum and inserts into the greater trochanter of the femur. Adductor Magnus originates from the pubis and ischial tuberosity and inserts into the linea aspera of the femur.

The Sartorius muscle originates at the anterior superior iliac spine and inserts at the tibia, allowing it to flex, abduct, and laterally rotate the hip, as well as flex the knee. The Quadriceps muscles have their origins at the femur and insert at the tibia via the patellar tendon. Gastrocnemius originates at the back of the femur and inserts at the heel via the Achilles tendon. Gluteus Maximus originates at the ilium, sacrum, and coccyx and inserts at the femur.

The correct answer is Tibialis Anterior, which is responsible for dorsiflexion and inversion of the foot. Gastrocnemius and Soleus are muscles primarily involved in plantar flexion, while Peroneus Longus is responsible for eversion of the foot.

The correct answer is Rectus Abdominis because it is a long muscle that runs vertically down the abdomen and helps flex the spine. The origin and insertion points described in the question match the characteristics of the Rectus Abdominis muscle.

The given description matches the origin and insertion points of the Vastus Medialis muscle.

The Extensor digitorum longus muscle originates at the posterior tibia and inserts at the distal phalanges of toes 2-5, allowing for extension of the toes.
