Anatomy: The Hand (Lecture 6)

From now on I'm going to read through the lecture notes and post about it instead of going to Brons lectures. What I'm doing is simply looking up each item that appears on his powerpoint slides.

Quiz Questions:
1. Which hand muscles act to clench your thumb against your index finger?
2. Name the fibrous band which arches over the carpus making the CARPAL TUNNEL
(through which the Flexor tendons of the digits and the median nerve pass).
3. Which thumb muscle is deep to the other two?
a. Abductor pollicis brevis
b. Flexor pollicis brevis
c. Opponens pollicis
4. Which two muscles work together to allow us to flex the metacarpal phalangeal joints while we extend the interphalangeal joints?
5. Between which two bones in the hand do you find a saddle joint?
6. What kind of joint is found between the metacarpals and the phalanges?
7. Which muscles connect into the dorsal extensor expansion?
8. Damage to which nerve causes you to loose your power grip?
