Forearm and Dorsum of Hand UE3 Flashcards
1
Q
cubital fossa
A
- triangular area on the anterior surface of the elbow
boundaries:
~ medially by the pronator teres
~ laterally by the brachioradialis
~ superiorly by an imaginary line b/n lateral and medial epicondyles
2
Q
cubital fossa contents
A
- biceps tendon
-brachial artery
-median nerve
-brahcial veins
3
Q
ulnar artery
A
- palpated on the lateral side of the FCU tendon
- gives the common interosseous artery
4
Q
radial artery
A
palpated through the forearm
5
Q
recurrent arteries participate?
A
in the anastomosis around the elbow
6
Q
what side do the anterior and posterior interosseous arteries travel on?
A
interosseous membrane
7
Q
median nerve
A
- lateral aspect of palm of hand and lateral 3 1/2 digits
- tips of lateral 3 fingers on dorsum of hand
8
Q
median nerve motor supply?
A
- most anterior forearm muscles
- most thenar muscles in the hand
- lumbricals 1 and 2
9
Q
ulnar nerve supply
A
- flexor carpl ulnaris
- medial 1 1/2 of flexor digitiorum profundus
- hypothenar muscles
- all intrinsic hand muscles except those innervated by median n
10
Q
ulnar nerve sensory distribution
A
- medial aspect of palm and dorsum of hand
- palmar and dorsal aspects of 1 ½ digits
11
Q
radial nerve
A
- the radial nerve supplies the
extensor (posterior) compartment - travels between the brachialis and
brachioradialis to emerge in the
forearm - deep (motor) and superficial
(sensory) branches - sensory distribution is shown in
the image on the right.
12
Q
wrist joint
A
- radiocarpal articulation
13
Q
metacarpophalangeal (MCP) joints
A
condyloid
14
Q
interphalangeral joints (IP)
A
- hinge joints (synovial)
- proximal (PIP)
- distal (DIP)
15
Q
movements of the wrist
A
- flexion
- extension
- abduction (radial deviation)
- adduction (ulnar deviation)
- pronation
- supination
