Answer 4

Flexor & Extensor Retinaculum

Question 5

Thickest- Palm (palmar aponeurosis

Question 7

What marks the lateral and medial boundaries of the central compartment?

Answer 7

Lateral and medial septa…they separate the central region from the hypo and thenar eminences

Question 8

Answer 8

The palmar extension of the carpal tunnel and carries tendons of the superficial and deep digital flexor muscles

Question 9

What are potential places in the hand that can harbor infection?

Answer 9

facial space that is continuous with the facial plane
along with spaces surrounding the thenar and hypothenar eminences
—-puncture woods (drill bits)

Question 10

Answer 10

Cephalic vein on the lateral side of the wrist

Question 11

What can be seen on the palmar side of the hand

Answer 11

transverse and longitudinal fissures

Question 12

In the hand what do the median and ulnar nerve control?

Answer 12

Short muscles of the hand

Question 13

In the hand what does the radial nerve control?

Answer 13

Entirely sensory over the dorsolateral part of the hand and thumb

Question 14

Where an the recurrent branch of the median nerve be seen?

Answer 14

surface of the thenar eminence and followed deep

—proximally it is seen branching just distal to the flexor retinaculum

Question 15

The recurrent branch of the median nerve serves as a motor nerve where?

Answer 15

To the thenar eminence muscles,

—except adductor pollicis

Question 16

Sensory innervation from the median nerve is where?

Answer 16

Palmar -lateral 1/2 of the thumb & pointer and middle finger, and half of the ring finger
Dorsally - tip of all the above

Question 17

Where does the ulnar nerve enter the hand?

Answer 17

lateral to the pisiform bone along with the ulnar artery

—ulnar nerve is superficial at this point

Question 18

The ulnar nerve is considered what?

Answer 18

the nerve of fine movement of the hand

Question 19

Sensory innervation from the ulnar nerve comes from where?

Answer 19

• Superficial branch to palmar surface
• dorsal cutaneous branch
• palmar branch

Question 20

Answer 20

hypothenar muscles, lumbricals 3 & 4, adductor pollicis and all dorsal and palmar interosseous

Question 21

Does the radial nerve control any part of the hand?

Answer 21

-Yes because of its innervation of muscles of the extensor compartment
