Introduction To Control and Coordination

● Organisms move in response to various kinds of stimuli like light, heat, nutrients/food, mate, etc.
● All the activities in animals are controlled and coordinated by the nervous and endocrine system.
● Hormones are chemical messengers that assist the nervous system in carrying out various functions. They are secreted by endocrine glands.
● Hormones in plants coordinate the movements.

Movement in organisms:

The ability of organisms to move certain body parts is movement. When they move from one place to another, it is called locomotion. Organisms show movements in response to stimuli.

The Nervous System

Neuron: Neuron is the structural and functional unit of the nervous system.

● Each neuron has three main parts: dendrites, cyton/soma/cell body, and axon.
● Dendrites receive impulses from other neurons.
● Cyton/soma processes the impulse.
● Axon transmits the impulse, either to another neuron or to muscles/glands, etc.
● Axon may be myelinated or unmyelinated.
● The impulse transmission is faster in myelinated neurons.
