Which proprioceptor is primarily responsible for detecting changes in muscle length and the rate of that change?
Answer: Muscle Spindle
Muscle spindles are intrafusal fibers that detect changes in muscle length and velocity, triggering the stretch reflex to protect the muscle.
The Golgi Tendon Organ (GTO) responds primarily to changes in:
Answer: Muscle tension
GTOs are located at the muscle-tendon junction and detect increases in muscle tension, triggering autogenic inhibition to protect the tendon from excessive force.
Which type of sensory receptor detects joint position and movement, contributing to proprioception?
Answer: Mechanoreceptors
Mechanoreceptors including Ruffini endings and Pacinian corpuscles in and around joints detect joint position, movement, and pressure changes.
Autogenic inhibition occurs when:
Answer: GTO activation causes relaxation of the agonist muscle
Autogenic inhibition is the relaxation of a muscle triggered by its own GTO, which inhibits motor neuron activity to protect the muscle-tendon unit from excessive tension.
The sensorimotor system integrates inputs from which three primary sources to maintain balance and coordinate movement?
Answer: Proprioception, vestibular, and visual systems
The sensorimotor system combines proprioceptive (joint/muscle feedback), vestibular (inner ear), and visual inputs to produce coordinated, stable movement.
In the NASM Corrective Exercise Continuum, which phase uses integrated dynamic movements to retrain neuromuscular control in functional contexts?
Answer: Integrate
The Integrate phase uses multiplanar, dynamic movement patterns that combine previously trained activation patterns into functional, real-world movements.
Which type of balance training involves maintaining the center of gravity over a stationary base of support without body movement?
Answer: Static balance
Static balance requires maintaining equilibrium without translating the base of support, such as holding a single-leg stance, training baseline proprioceptive control.
