except thumb with 2

Question 7

strong bands of deep fascia that hold the long FLEXOR tendons in position at the wrist

Answer 7

FLEXOR RETINACULUM

Question 8

strong bands of deep fascia that hold the long EXTENSOR tendons in position at the wrist

Answer 8

EXTENSOR RETINACULUM

Question 9

an osteofascial tunnel for the
passage of the median nerve
and the flexor tendons of the
thumb and fingers

Answer 9

carpal tunnel

Question 10

• compression of the median
nerve as it passes through the
carpal tunnel
• caused by pinching and gripping
activities with the wrist bent
• made worse with repetitive
flexion and extension activities at
the wrists

Answer 10

CARPAL TUNNEL SYNDROME

Question 11

triangular
- occupies central area of palm
- apex attached to the distal
border of the flexor
retinaculum
- base divides at the bases of
the fingers into 4 slips

Answer 11

PALMAR APONEUROSIS

Question 12

• strong fibrous sheath at the
  anterior surface of each finger,
  from the head of the metacarpal
  to the base of the distal phalanx
• proximal end is open, whereas
  the distal end is closed

Answer 12

FIBROUS FLEXOR SHEATHS

Question 13

allow the long tendons to move
smoothly, with a minimum of
friction, beneath the flexor
retinaculum and the fibrous flexor
sheaths
a. Radial bursa
b. Ulnar bursa

Answer 13
