Question 26

Muscles may shorten or lengthen in the absence of a contraction through passive movement caused by other contracting muscles.

Question 27

Muscles are usually grouped together according to their eccentric function.

Question 28

Eccentric actions occur when muscles lengthen under tension to control the joints moving with gravity or an external resistance.

Question 29

The quadriceps muscle group functions as a decelerator to knee joint flexion in weight-bearing movements by contracting concentrically to prevent too rapid of a downward movement.
