Skeletal Muscle
Two major types of fiber type arrangement.
Pennate & Parallel
Contraction in which no movement occurs.
Isometric
The term for the primary muscle in a movement
Efferent nerves carry this type of signal...
Motor
The distal attachment point of a muscle
Insertion
This fusiform muscle is responsible for elbow flexion.
Biceps Brachii
Contraction at a constant speed
Isokinetic
Assists / helps muscle action.
Synergyst
Response to rate of tension development and results in reflex contraction
Muscle Spindle
The ability of a muscle to be stretched or to increase in length
Extensibility
The 3 functions of muscle are...
Protection, Posture, Heat Production
The ability of a muscle to return to normal resting length following a stretch
Elasticity
DD: This type of muscle prevents excess movement.
Neutralizer
Subconscious mechanism by which body is able to regulate posture & movement by responding to stimuli originating in proprioceptors of the joints, tendons, muscles, & inner ear
Proprioception
Muscles work in groups rather than independently to achieve a given joint motion
Aggregate muscle action
This type of muscle has several tendons with fibers running diagonally between them.
Multipennated
The ability to respond to a stimulus.
Irritability
The wrist extensors act as a ___________________ to the finger flexors.
True Synergist
DD: As one muscle contracts the opposing muscle gets a signal to relax, this is termed...
Reciprocal Inhibition
Pertaining usually to muscles within or belonging solely to body part upon which they act
Intrinsic
This type of muscle is described sometimes as being triangular, fan-shaped or convergent.
Radiate (Triangular, Convergent)
This type of contraction occurs when resistance torque overcomes muscular torque
Eccentric
During walking, the hip flexors contract on the lead leg while the gluteus maximus contracts on the rear leg. This describes a...
Force Couple
Level 3 (middle level) of CNS control.
Formed by fascial tissue to keep tendons close to the body
Retinaculum
