Describe a muscle spindle
Step by step
Solved in 2 steps
- Describe a muscle spindle and its function considering the following items. Use all terms in paragraph form to describe: - Extrafusal fibers - Intrafusal fibers - Alpha motor neurons - Gamma motor neurons - Capsule - Contraction - Afferent nerve fiber - Somatic reflex (as in the patellar reflex)Explain the role of stretch receptors*When dynamic y-motor neurons are activated at the same time as a-motor neurons to muscle, [A] prompt inhibition of discharge in spindle la afferents takes place. [B] clonus is likely to occur. [C] the muscle will not contract. [D] the number of impulses in spindle la afferents is smaller than when a discharge alone is increased. [E] the number of impulses in spindle la afferents is greater than when a discharge alone is increased.
