Chapter 7 - Human Movement Science

The collective components and structures that work together to move the body: muscular, skeletal, and nervous systems.

A concept that describes the human body as a chain of interdependent links that work together to perform movement.

The concept describing the integrated functioning of multiple body systems or regions of the body.

Study of movement as it relates to anatomy and physiology.

The science concerned with the internal and external forces acting on the human body and the effects produced by these forces.

Movement of a limb that is visible

Description of joint surface movement; consists of three major types: roll, slide, and spin

An imaginary bisector that divides the body into left and right halves

Extension of a joint beyond the normal limit or range of motion

An imaginary bisector that divides the body into front and back halves

Bending of the spine from side the side

An imaginary bisector that divides the body into top and bottom halves

The ability of soft tissues to return to resting length after being stretched

The normal extensibility of soft tissues that allow for full ROM of a joint

A state where a lack of neuromuscular support leads to a joint having more range of motion than it should

When range of motion at a joint is limited

the primary muscle providing force for a movement

muscles that assist agonists to produce a movement

muscles that contract isometrically to stabilize the trunk and joints as the body moves

when a muscle is automatically activated in anticipation of a movement

muscles on the opposite side of a joint that are in direct opposition of agonist muscles

the resting length of a muscle and the tension the muscle can produce at this resting length

when a muscle’s resting length is too short of too long, reducing the amount of force it can produce

when an agonist receives a signal to contract, its functional antagonist also receives an inhibitory signal allowing it to lengthen
