WebAug 8, 2024 · Upon stretching the muscle, (for example through a patellar tendon tap) the muscle spindle will stretch and sensory afferent fibres will fire. This in turn will cause the α-motor neurons to fire and lead to muscle contraction through the reflex arc. The contraction of muscle causes the intrafusal fibres to become slack, reducing Ia afferent ... WebName the five types of parallel muscles. flat muscles.
