Definition of Extrafusal. Meaning of Extrafusal. Synonyms of Extrafusal

- Extrafusal muscle fibers are the standard skeletal muscle fibers that are innervated by alpha motor neurons and generate tension by contracting, thereby...
- neurons innervate intrafusal fibers of muscle spindles with collaterals to extrafusal fibers - a type of slow twitch fiber. Also, axons of alpha, beta, and...
- lower motor neurons of the brainstem and spinal cord. They innervate extrafusal muscle fibers of skeletal muscle and are directly responsible for initiating...
- spindle are called extrafusal muscle fibers. Muscle spindles have a capsule of connective tissue, and run parallel to the extrafusal muscle fibers. Muscle...
- of muscle fiber they innervate: Alpha motor neurons (α-MNs) innervate extrafusal muscle fibers, the most numerous type of muscle fiber and the one involved...
- action potential frequency signals the force being developed by 10-20 extrafusal muscle fibers in the muscle. Average level of activity in a tendon organ...
- nervous system (CNS) to the periphery. Alpha motor neurons innervate extrafusal muscle fibers, which are the main force-generating component of a muscle...
- (efferent) fibers. Intrafusal muscle fibers are not to be confused with extrafusal muscle fibers, which contract, generating skeletal movement and are innervated...
- Alpha motor neurons target extrafusal muscle fibers. The motor nerves ****ociated with these neurons innervate extrafusal fibers and are responsible for...
- used in the actual force for muscle contraction and therefore innervate extrafusal muscle fibers (muscle fibers outside of the muscle spindle). Gamma motor...
