Study Notes

Proprioception

Proprioception is the ability to sense the position, orientation, and movement of one's body in space.

Proprioceptors

Proprioceptors are specialized sensory receptors that detect changes in muscle length, tension, and movement.

Muscle Spindles

Muscle spindles are a type of proprioceptor that signals information about muscle length and velocity.
They are embedded within muscle fibers and provide feedback to the nervous system about muscle stretch and movement.

Intrafusal Muscle Fibers

Intrafusal muscle fibers are a type of muscle fiber that is found within muscle spindles.
They are specialized to detect changes in muscle length and velocity.

Gamma Motor Neurons

Gamma motor neurons are responsible for regulating the sensitivity of muscle spindles.
They innervate intrafusal muscle fibers and control the amount of stretch or tension required to activate muscle spindles.
