Introductio
The human body is a complex machine performing tons of functions and processes to maintain and
sustain life. Explore how the body controls its movements and coordinates its actions with other parts of
the body and the environment by exploring notes for Class 10 Chapter 7 Control and Coordination
The Nervous Syste
Movement in organism
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
Introduction to control & coordinatio
• Organisms move in response to various kinds of stimuli like light, heat, nutrients/food, etc
• All the activities in animals are controlled and coordinated by the nervous and endocrine
systems
• Hormones are chemical messengers, which assist the nervous system in carrying out various
functions. They are secreted by endocrine glands
• Hormones in plants coordinate the movements

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 non-myelinated
• The impulse transmission is faster in myelinated neurons
