Exam Questions and CORRECT Answers
How many muscles insert onto the greater tubericle of the humerus? lesser tubercle? -
CORRECT ANSWER - Greater = 3 (supra, infra, teres min)
Lesser = 1 (subscap)
Innervation of the Rhomboids: - CORRECT ANSWER - Dorsal Scapular Nerve (C5)
Innervation of the Lat Dorsi? - CORRECT ANSWER - Thoracodorsal Nerve
Most muscles in the upper limb rotate: - CORRECT ANSWER - Medially, only the infra
and teres minor rotate laterally
What is the biggest upper limb nerve? - CORRECT ANSWER - Radial
What joints have articular discs? - CORRECT ANSWER - Sternoclavicular,
Acromioclavicular, distal radial-ulnar joint
What bones have condyles? - CORRECT ANSWER - Fibula, Tibia
The humerus has the trochlea and capitilum instead but has epi-condyles
Do both the radial and ulnar nerve bifurcate? - CORRECT ANSWER - Ulnar Nerve: no
Ulnar Artery: yes --> anterior and posterior interoussous membrane
Radial Nerve: yes --> superficial and deep radial nerve
(raymond needs 2 shoes)
Radial Artery: no
, Carpi radialis will ______ while carpi ulnaris will _____ - CORRECT ANSWER -
Radialis --> abducts
Ulnaris --> adducts
True or False: Both the ulnar nerve and artery as well as the radial nerve and artery do not pass
through the carpal tunnel - CORRECT ANSWER - False:
Ulnar nerve and artery do not (UNA)
Radial artery does not but the radial nerve does (RA)
The brachioradialis is weird for 2 reasons: - CORRECT ANSWER - 1) it doesn't cross the
wrist
2) It is a superficial posterior forearm muscle that FLEXES the elbow
True or False:
Both the flexor digitorum superficialis and profundus will flex all of the joints they pass through
- CORRECT ANSWER - True
Does the extensor digitorum and mini me both insert on the distal phalanyx? - CORRECT
ANSWER - Yes, they do on the extensor expansions of the distal phalynx.
The insertion of the four outcropping muscles are: - CORRECT ANSWER - extensor
indices: extensor expansion
abductor pollices longus: base of metacarpal #1
extensor pollices brevis: Proximal phalanyx
extensor pollices longus: Distal phalanyx
The ulnar nerve pierces what in the forearm and passes what in the wrist? - CORRECT
ANSWER - The flexor carpi ulnaris and passes lateral of the pisiform
