Question
Chapter 13, Problem 19CP
Summary Introduction
To determine:
The affect on the speed of the reflex on stimulation of gamma motor neurons for the patellar reflex (knee jerk)
Introduction:
Patellar reflex is a monosynaptic reflex which is used to detect the working of the segments L2, L3 and L4. Intrafusal fibers have the ability to detect the change in the length of the fibers. These fibers are penetrated by two axons also. Gamma motor neurons are the neurons that are involved in the muscular contraction.

Notably, some researchers have noted a delay in the reflex response after muscle fatigue. With your understanding of the stretch reflex, which of the following is the most logical contributing factor to the injury? a. the distraction of the game causes inhibitory impulses to be sent down from the somatosensory cortex, so muscles are not operating at full capacity b. the proprioceptors adapt and become less sensitive c. there is an increase in time to muscle contraction after triggering a reflexarrow_forward
