Flexibility offers these benefits

Maintains ability to do daily activities Prevents or decreases back pain Increases balance Reduces stress

Which type of stretching exercise involves alternating between contraction and relaxation and stretching either the agonist or the antagonist muscle in a particular limb?-

PNF stretching

A flexion motion is characterized by-

a decrease in the angle of the limbs surrounding the joint.

Abduction motion means that

a limb is moving away from the body.

The stretch reflex is

a muscular response that initiates a contraction to prevent overstretching.

Research has shown that stretching prior to activity greatly reduces the risk of injury

Which of the following is an example of a hinge joint?

knee

Flexibility enables your body to

move through a range of motion so that you can perform daily activities

The ability of the head to move side to side is an example of what kind of joint?

pivot

A muscle spindle is an organelle that signals the muscle to

reflexively contract (tighten) when overstretched.

Which two types of joints are rare in the human body?

saddle and pivot

Which of the following is an example of a flexion motion? (Select all that apply)

take a step, kick a ball

Range of motion is limited primarily by

the type of joint in question.
