kinesiology set 1

List the four bones that comprise the axial skeleton.

Skull, Vertebral column, Sternum, Ribs

List the four properties of skeletal muscle.

Contractility, Irritability, Extensibility, Elasticity

Contractility

ability to produce active tension

Irritability

Ability to respond to a stimulus

Extensibility

Ability to be elongated beyond resisting length

Elasticity

Ability to rebound existing length after being stretched

Provide five key functions of bone.

Support, Protection, movement, blood cell production, storage

Ligament

Which movement occurs in the horizontal plane?

turnout, spin turns, torso twist

Which is the most common type of lever in the body?

Third class levers

What term describes shortening contraction (movement in the direction of the muscle or effort)?

Concentric contraction

What is the technical term for a muscle contraction that involves a lengthening of the muscle?

Eccentric contraction

What is a connective tissue that connects muscles to the bone?

A Tendon

Name the type of muscle contraction without visible joint movement.

Isometric contraction

Name the structure responsible for providing the compressive strength of bone.

Calcium salts

Sagittal/ML

Frontal/AP

Jumping jack, brush side

Horizontal/Vertical

Torso twist

Rotary Motion

Bones are restricted at joints

Resistance

Tendency for the resistance to produce rotation in the opposite direction

Lever

A rigid bar revolving about a fixed point called the axis

Effort

A rigid bar revolving about a fixed point called the axis
