Terminology / general concepts

Question 1

anterior = 
posterior = 
ligaments on medial = 
ligaments on lateral =
abduction = 
adduction =

Answer 1

• palmar
• dorsal
• ulnar
• radial
• radial deviation
• ulnar deviation

Question 2

coronal plane movements

Answer 2

• coronal plane movts relate to axis through digit 3

- i.e. finger abduction = moving digits away from digit 3 + reverse for adduction

Question 3

arches of the hand

Answer 3

Proximal transverse arch = more rigid, formed by distal row of carpal bones
Distal transverse arch = more mobile (esp at sides), through the MCP joints
Longitudinal arch = follows the 2nd and 3rd rays + provides longitudinal stability

Question 4

thumb movts (get me to demonstrate)

Answer 4

• flexion
• extenstion
• opposition
• adduction
• abduction
