Chapter 9: Muscular Training: Foundation and Benefits Flashcards
Tendon
A band of fibrous tissue forming the termination of a muscle and attaching the muscle to a bone.
Axial Skeleton
The bones of the head, neck, and trunk.
Central Nervous System
The brain and spinal cord.
Ligaments
A strong, fibrous tissue that connects one bone to another.
Axis of Rotation
The imaginary line or point about which an object, such as a joint, rotates.
Sagittal
The longitudinal plane that divides the body into right and left portions.
Frontal
A longitudinal section that runs at a right angle to the sagittal plane, dividing the body into anterior and posterior portions,
Transverse
Anatomical term for the imaginary line that divides the body, or any of its parts, into upper (superior) and lower (inferior) parts. Also called the horizontal plane.
Flexion
The act of moving a joint so that the two bones forming it are brought closer together.
Extension
The act of straightening or extending a joint, usually applied to the muscular movement of a limb.
Abduction
Movement away from the midline of the body.
Adduction
Movement toward the midline of the body.
Supination
External rotation of the forearm (radioulnar joint) that causes the palm to face anteriorly.
Pronation
Internal rotation of the forearm causing the radius to cross diagonally over the ulna and the palm to face posteriorly.
Peripheral Nervous System
All nervous structures located outside of the CNS.
Ganglia
nerve cell bodies associated with nerves
Proprioception
Sensation and awareness of body position and movements.
Autogenic Inhibition
An automatic reflex relaxation caused by stimulation of the Golgi tendon organ (GTO).
Reciprocal Inhibition
The reflex inhibition of the motor neurons of antagonists when the agonists are contracted.
Gait
The manner or style of walking.
Muscle Spindles
The sensory organ within a muscle that is sensitive to stretch and thus protects the muscle against too much stretch.
Golgi Tendon Organ
A sensory organ within a tendon that, when stimulated, causes an inhibition of the entire muscle group to protect against too much force.
Proprioceptive Neuromuscular Facilitation
A method of promoting the response of neuromuscular mechanisms through the stimulation of proprioceptors in an attempt to gain more stretch in a muscle; often referred to as a contract-relax method of stretching,
