Question
Chapter 44.4, Problem 3R
Summary Introduction
To review:
The mechanism by which one muscle gets contracted and another gets relaxed by the same stimulus, in the knee-jerk reflex circuit.
Introduction:
A reflex reaction occurs in the situation requiring quick response, in which conscious processing of information is not required. The reaction is involuntary and autonomic or unconscious. For example, immediate removal of foot stepping on a pin and salivating on the sight and smell of tasty food.
The knee-jerk reflex response is required in the normal movement of legs. In this response the muscles act antagonistically, i.e., while one pair is relaxed, and another one is in the contracted state.

Why is an interneuron needed to provide reciprocal inhibition of the flexor muscle when an extensor muscle is activated?
What are the neural pathways involved in the knee-jerk reflex?
Check this reflex by gently dorsiflexing a classmate’s foot then using a reflex hammer to strike the Achilles tendon. What was the result? Do you normally get the observed reaction when the gastrocnemius muscle is contracted?
