Chapter 6.5, Problem 22CC

(a)

Summary Introduction

To determine: The part of the simple neural reflex that depicts the brain and spinal cord.

Introduction: The physiological reflex that controls the pathways is either mediated by the nervous system, the endocrine system, or a combination of two. The reflex that is solely mediated by the nervous system is known as a simple neural reflex.

(b)

Summary Introduction

To determine: The part of the simple neural reflex that depicts the central and peripheral sense organs.

Introduction: The neural reflex is a type of physiological reflex that controls the pathways of the nervous system. It occurs because the sensory neurons do not tend to pass directly into the brain; rather, they synapse in the spinal cord. This neural reflex explains how an internal or external change brings a change in the response.

(c)

Summary Introduction

To sketch: The negative feedback loop in a simple neural reflex that turns off the reflex by drawing a dashed line.

Introduction: The neural reflex controls the pathways of the nervous system in the form of a reflex arc. The stimulus activates the sensory receptor, after which the input signal is transferred to the central nervous stem. Then, the signal reaches the target and generates the response.
