Summary Introduction

To describe: The principles related to the development of the nervous system and hierarchy of control.

Introduction: The central nervous system has a significant role in the regulation of behavior. It includes the brain and the spinal cord, which are both encased in the bone, which explains their significance. Both the brain and spinal cord catch signals from the afferent neurons and transmit signals to tissues and glands through the efferent neurons.

Explanation of Solution

The nervous system is observed primarily as a heterogeneous network of interconnected nerve cells that regulates two functions. The first is to propitiate the behavioral communications of an animal with its environment, which covers other animals and, thus, social behaviors as well. The second is to monitor essential physiological methods in the body itself like metabolism, electrolyte stability, respiration, and temperature regulation.

Overall, specific biological roles are characterized by how they increase the survival of the species, one most significant circumstance in evolution, as well as the survival of particular animals. Three broad groups of durability functions with properly regulated active functions are familiar to all animals with a nervous system: ingestive, defensive, and reproductive.
