Extensors of the hand
Correct Answer
A. Extends Hand
Explanation
The correct answer is "Extends Hand" because the extensors of the hand are responsible for extending the hand at the wrist joint.

This action is important for various activities that require extending the hand, such as reaching, grasping, and pushing objects away.

The extensors of the foot are a group of muscles that are responsible for extending the foot. This means that they help to lift the foot upwards, away from the ground. These muscles work in conjunction with other muscles in the lower leg to allow for movements such as walking, running, and jumping. By extending the foot, these muscles provide stability and support during weight-bearing activities.
17.
Flexors of the hand
Correct Answer
A. Flex hand
Explanation
The correct answer is "flex hand" because the question is asking for the flexors of the hand, which refers to the muscles responsible for bending the hand at the wrist joint. Flexing the hand involves the contraction of muscles such as the flexor carpi radialis, flexor carpi ulnaris, and flexor digitorum superficialis, among others. Therefore, "flex hand" is the appropriate response as it accurately identifies the action performed by the flexor muscles of the hand.
18.
Flexors of the foot
