Question
Chapter 13, Problem 27RQ
Summary Introduction
To determine:
The effects on muscle tone, when the stimulation of a sensory neuron innervates an intrafusal muscle fiber.
Introduction:
The intrafusal muscle is a type of skeletal muscles which act as sensory organs and help in detecting the change in length of a muscle.
