Answer 3

Insertion

Question 4

The more distal a muscle’s origin, the more ____ the insertion?

Answer 4

Distal

Question 5

Extrinsic versus intrinsic hand muscles

Answer 5

Extrinsic= located distal to the place that it is acting, intrinsic= located IN the hand

Question 6

What are the two compartments of the forearm?

Answer 6

1) anterior flexor compartment

2) posterior extensor compartment

Question 7

The anterior compartment is the what bundle of muscles?

Answer 7

Flexor-pronator bundle of muscles

Question 8

The anterior compartment is organized into 3 layers

Answer 8

1) superficial layer
2) intermediate layer
3) deep layer

Question 9

Muscles in the forearm cause action in?

Answer 9

Wrist

Question 10

Muscles in the arm cause action in the?

Answer 10

forearm

Question 11

What is the odd ball in the posterior compartment?

Answer 11

Brachioradialis

Question 12

Why is the brachioradialis odd?

Answer 12

It is located in the posterior flexor compartment but is innervated by the radial nerve and flexes forearm (not wrist)

Question 13

What are the anterior superficial forearm muscles

Answer 13

Pronator teres, palmaris longus, flexor carpi ulnaris, flexor carpi radialis

Question 14

All anterior superficial forearm muscles originate from?

Answer 14

Common flexor tendon

Question 15

What are the anterior intermediate muscles of forearm?

Answer 15

Flexor digitorum superficialis

Question 16

What is the only anterior intermediate muscles of the forearm innervated by median nerve?

Answer 16

Flexor carpi ulnaris

Question 17

The anterior intermediate forearm muscle originates from? Innervation?

Answer 17

Common flexor tendon and median nerve

Question 18

What are the anterior deep muscles of the forearm?

Answer 18

Flexor digitorum profundus, flexor pollicis longus, pronator quandratus

Question 19

What are the anterior deep muscles of the forearm originates from?

Answer 19

Shafts of ulna and radius

Question 20

What are the layers of posterior compartment of forearm?

Answer 20

1) superficial layer

2) deep layer

Question 21

What is the odd ball in the posterior extensor-supinator compartment of forearm?

Answer 21

Brachioradialis

Question 22

Why is the brachioradialis an odd ball in the posterior compartment of forearm?

Answer 22

It is NOT an extensor

Question 23

What is the tendon that is missing if you a part of the 14% evolutionary advanced people?

Answer 23

Pulmaris longus (it helps with grip)

Question 24

All of the posterior extensor compartment of the forearm is innervated by?

Answer 24

Radial nerve

Question 25

What is elbow tendinitis (tennis elbow)?

Answer 25

Repetitive use of superficial extensor muscles that cause radiating pain over the lateral epicondyle and down posterior forearm

Question 26

Elbow tendinitis is different from golfing elbow how?

Answer 26

Golfing is on medial epicondyle

Question 27

How is elbow tendinitis fixed?

Answer 27

Worst case scenario is surgery, but steroid injections are the “go-to”

Question 28

Where is a good place to take a pulse?

Answer 28

Radial artery, it is covered only by skin and fascia at the distal radius (lateral FCR)
