Flashcards in Upper limb 2 Deck (33):
1

what compartment of the arm flexes the elbow and the shoulder joint

the anterior compartment of the arm

2

name the 3 muscles that make up the anterior compartment of the arm

biceps brachii, coracobrachialis and the brachial

3

where does the biceps brachii arise from

there are two heads - the short head arises from the coracoid process of the scapula and the long head arises from the supraglenoid tubercle

4

where does the biceps brachii tendon insert

onto the tuberosity of the radius

5

what are the actions of the bicep brachii muscle

flexion of the elbow joint, flexion of the shoulder joint and supinates the forearm

6

where does the short head of the biceps brachii arise from

the coracoid process of the scapula

7

where does the long head of the biceps brachii arise from

the supra-glenoid tubercle

8

what other muscle arises from the same location as the short head of the biceps brachii

the coracobrachialis

9

what are the attachments of the coradobrachialis muscle

the coracoid process of the scapula and the medial shaft of the humerus

10

what are the actions of the cracobrachialis muscles

flexion of the shoulder joint and adduction of the arm

11

what are the attachments of the brachialis muscle

from the distal half of the humerus to the coronoid process of the ulnar bone

12

what are the actions of the brachialis muscle

flexion of the elbow joint

13

what nerve innervates all of the biceps muscles

the musculocutaneous nerve

14

what muscle does the musculocutaneous pierce through on the way to the arm

the coracobrachialis

15

besides motor innervation to the biceps, what is the other role of the musculocutaneous nerve

sensory innervation to the lateral aspect of the forearm

16

what are the branches of the brachial artery

the radial and the ulnar artery

17

name the deep branch that is given off of the radial artery

the profound brachii

18

what is the role of the median nerve

innervates most of the forearm muscles

19

what cords form the median nerve

the lateral and the medial cords

20

what is the role of the ulnar nerve

innervation of some muscles in the forearm and sensory to some aspects of the hand

21

damage to what will result in damage tot he ulnar nerve

the medial epicondyle

22

damage to the surgical neck of the humerus will damage what nerve

the axillary nerve

23

damage to what will result in damage of the radial nerve

the radial groove of the humerus

24

what forms the base of the cubital fossa

an imaginary line between the 2 epicondyles of the humerus

25

what muscle forms the medial border of the cubital fossa

pronator teres

26

what muscle forms the lateral border of the cubital fossa

the brachiradialirs

27

what nerve innervates the tricep muscles

the radial nerve

28

what cord does the radial nerve come from

the posterior cord

29

what ligaments are found in the elbow

the ulnar collateral, the radial collateral and the annular

30

name the 3 flexors of the elbow

the biceps brachii, the brachioradialis and the brachialis

31

names the elbow extensor muscles

the triceps and the anconeus

32

name the 2 supinators of the arm

the biceps brachii and the supinator muscle

33

name the pronator muscles

the pronator teres and the pronator quadratus
