NERVOUS SYSTEM

Ø The nervous system is a highly complex part of an animal that coordinates its actions and sensory information by transmitting signals to and from different parts of its body.

Ø The nervous system detects environmental changes that impact the body, then works in tandem with the endocrine system to respond to such events.

Structure of Neuron:

Ø A neuron typically consists of three basic parts:

1. Cyton

2. Dendrites

3. Axon

Types of Neurons:

Ø Unipolar neurons: Only one nerve process arises from the cyton which acts as both axon and dendron

Ø Bipolar neurons: The cyton gives rise to two nerve processes of which one acts as an axon while another as a dendron.

Ø Multipolar neurons: The cyton gives rise to many dendrons and an axon
