32
Q

What keeps the long flexors of the hand in place during flexion

A

Flexor sheath

33
Q

How does flexor sheath permit flexion?

By being thick opposite the phalanges and thin opposite the joints

34
Q

Opposition is a mixture of what movements?

A

Flexion and medial rotation

Why is adduction and abduction of thumb at 90 degrees to other fingers?

A

Because the fifth metacarpal is rotated medially at 90 degrees
