Which of the types of muscle contraction is usually utilized in causing an object's deceleration?

eccentric

All of the following are movements of the wrist except:

extension

Isometric contractions are eccentric or concentric.

false

It is the isotonic contraction that involves tension developed within muscle but joint angles remain constant.

false

Levers rotate about an axis of rotation as a result of a force being applied to cause movement in the same direction as the resistance.

false

The medial malleolus is an anatomical landmark located on the fibula.

false

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.

false

first class

pes planus

flat footed

dick

flexor digitorum

Biomechanics is the study of mechanics related to the functional and anatomical analysis of biological systems.

true

Concentric muscle actions are the shortening contraction of muscles against gravity or a resistance.

true

Isometric contraction involves tension developed within the muscle but the joint angles remain constant.

true

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