Answer 21

Extension

Question 22

Anterior movement of the thumb

Answer 22

Abduction

Question 23

Posterior movement of the thumb

Answer 23

Adduction

Question 24

When you do opposition of the thumb what type of movement are you doing?

Answer 24

Abduction and Flexion using the carpal metacarpal joint

Question 25

Answer 25

metacarpalphalangeal joints

Question 26

Interphalangeal joints allows you to do what?

Answer 26

Flex and extension

Question 27

Anterior nerves of the forearm

Answer 27

Musculocutaneous n. (skin) Median n. (muscles) - main one Ulnar n. (muscles)
