Module 6 Anatomy And Physiology

Front 1

Origin

Back 1

The point at which a muscle's tendon attaches to the more stationary bone.

Front 2

Insertion

Back 2

The point at which a muscle's tendon attaches to the more moveable bone.

Front 3

Belly

Back 3

The largest part of the muscle, which actually contains the muscle cells.

Front 4

Mastication

Back 4

The process of chewing

Front 5

Extrinsic Hand Muscles

Back 5

Muscles of the forearm that create movement in the hands

Front 6

Intrinsic Hand Muscles

Back 6

Muscles in the hand that produce movement in the hand

Front 7

Several muscles work together to laterally rotate the thigh. What do we call an entire group of muscles that work together?

Back 7

Synergists

Front 8

One of the jobs of the flexor digitorum superficialis is to flex the wrist. When working in this fashion, does this muscle form a first-class lever, a second-class lever, or a third-class lever?

Back 8

In this situation, we have a second-class lever. Look at the flexor digitorum superficialis. The tendons attach near the ends of the fingers. When it flexes the hand, the weight it lifts is mostly the palm of the hand. The wrist is the fulcrum, and the resistance is between the effort and the fulcrum.

e. deltoid
f. pectoralis major
g. linea alba
h. rectus abdominis

Front 13

Which structure above is not a muscle?

Back 13

The linea alba is not a muscle, it is a band of connective tissue that binds all of the abdominal muscles

Front 14

Which of the muscles above act on the arm?

Back 14

The deltoid and pectoralis major muscle move the arm.

Front 15

Which of the muscles in the figure move the vertebral column?

Back 15

The rectus abdominis, external oblique, and internal oblique muscles move the vertebral column.

d. pronator teres
e. flexor carpi radialis
f. triceps brachii
g. extensor carpi ulnaris
h. extensor carpi radialis longus
i. extensor carpi radialis brevis
j. extensor digitorum
k. extensor retinaculum

Front 18

Which of the structures in the figure above is not a muscle? What is its job?

Back 18

The extensor retinaculum is not a muscle--its job is to secure the extensor tendons so that they do not "bow out" when the muscles contract.

Front 19

What is the difference between extrinsic and intrinsic hand muscles?

Back 19

Extrinsic hand muscles are muscles in the forearm that create movement in the hands, while intrinsic hand muscles are muscles in the hand that produce movement in the hand.

Front 20

Back 20

a. gluteus medius
b. biceps femoris
c. vastus lateralis
d. gluteus maximus
e. adductor magnus

n. vastus medialis

Front 21

List all the muscles that are involved in flexing the thigh. List their antagonists.

Back 21

The thigh flexors are the tensor fasciae latae, rectus femoris, sartorius, iliacus, psoas major, and adductor longus. The antagonists are the extensors: gluteus maximus, semitendinosus, semimembranosus, biceps femoris, and adductor magnus.

Front 22

List all of the muscles that are involved in abducting the thigh. List their antagonists.

Back 22

The abductors of the thigh are the gluteus maximus, gluteus medius, gluteus minimus, and tenor fasiae latae. Their antagonists are the adductors--the adductor longus, the adductor magnus, and the gracilis.

Front 23

There are two muscles that flex the forearm. List them. List their antagonist.

Back 23

The biceps brachii and the brachioradialis flex the forearm. Their antagonist is the triceps brachii.

Front 24

There are two supinators of the forearm at the elbow. List them. List their two antagonists.

Back 24

The two supinators of the forearm are the supinator and the biceps brachii. Their antagonists, pronators, are the pronator teres and the pronator quadratus.
