Question 7

Which muscle is correctly matched to its origin and insertion?
A) pectineus; originates on the crest of the ilium and inserts into the fascia lata
B) sartorius; originates on the ischium and pubic symphysis and inserts on the medial surface of the tibia
C) gracilis; originates on the ischial tuberosity and inserts on the tibia
D) gluteus medius; originates on the ilium and the transverse processes of the last sacral and first caudal vertebrae and inserts on the femur

Accepted Answer

The gluteus medius muscle originates on the ilium, specifically the outer surface of the ilium between the iliac crest and the posterior gluteal line, as well as the transverse processes of the last sacral and first caudal vertebrae. Its insertion is on the greater trochanter of the femur. Option A is incorrect as the pectineus muscle originates from the pectineal line and superior ramus of the pubis and inserts on the pectineal line of the femur. Option B is incorrect as the sartorius muscle originates on the anterior superior iliac spine and inserts on the medial surface of the tibia. Option C is incorrect as the gracilis muscle originates on the pubic symphysis and ischiopubic ramus and inserts on the medial surface of the tibia.

Question 8

Which of the four abdominal muscles listed below do all of the other three muscles insert on?
A) transverse abdominis
B) internal oblique
C) rectus abdominis
D) external oblique

Accepted Answer

The rectus abdominis is the only muscle of the four that all others insert on. The external oblique and internal oblique muscles insert on the linea alba and the pubic crest, while the transverse abdominis inserts on the pubic crest, pubic symphysis, and the xiphoid process of the sternum.

B) flexor digitorum longus
C) fibularis longus
D) fibularis tertius
E) extensor digitorum longus

Question 12

Which of the three muscles of the pig pectoralis group is NOT found in humans?
A) superficial pectoral
B) posterior deep pectoralis major
C) anterior deep pectoralis minor

Accepted Answer

The superficial pectoral muscle is only found in four-legged animals like pigs and other quadrupeds. Humans only have the pectoralis major and pectoralis minor muscles in their chest.

Question 13

Which of the following muscles is NOT a component of the quadriceps femoris?
A) biceps femoris
B) vastus lateralis
C) vastus intermedius
D) vastus medialis
E) rectus femoris

Accepted Answer

The biceps femoris is a muscle in the posterior compartment of the thigh and is not a component of the quadriceps femoris, which is located in the anterior compartment of the thigh.

Question 14

How many points of origin does the triceps brachii have?
A) one
B) two
C) three
D) four

Accepted Answer

The triceps brachii has three points of origin, which are the long head, medial head, and lateral head, hence the prefix "tri-" in its name.

Question 15

The biceps brachii functions as which of the following?
A) a flexor of the forelimb
B) an extensor of the forelimb
C) a supinator of the paw
D) an extensor of the carpal joints
E) a flexor of the digits

Accepted Answer

The biceps brachii muscle is a flexor of the forelimb, specifically responsible for flexion at the elbow joint.

Question 16

In pigs, the pectoralis group of muscles consists of ________ muscles, while in humans it consists of ________.
A) one; three
B) two; three
C) three; one
D) three; two

Accepted Answer

Question 17

Which muscle is located on the ventrolateral surface of the humerus and functions to flex the forelimb?
A) biceps brachii
B) brachialis
C) triceps brachii
D) brachioradialis

Accepted Answer

The brachialis muscle is located on the ventrolateral surface of the humerus and its primary function is to flex the forearm. The biceps brachii also helps with forearm flexion, but it is located on the ventromedial aspect of the humerus. The triceps brachii is located on the dorsolateral aspect of the humerus and its primary function is elbow extension. The brachioradialis is located on the forearm and assists with forearm flexion, but not to the extent that the brachialis does.

Question 18

A) A
B) B
C) C
D) D

Accepted Answer

Question 19

Which muscle of the quadriceps femoris group lies deep to the rectus femoris?
A) vastus intermedius
B) vastus lateralis
C) vastus medialis
D) semimembranosus

Accepted Answer

The vastus intermedius muscle lies deep to the rectus femoris muscle in the quadriceps femoris group. The vastus lateralis and vastus medialis muscles are located laterally and medially, respectively, to the rectus femoris, while the semimembranosus muscle is located in the posterior thigh.

Question 20
