Control And Coordination Class 10
Coordination
The working together of various organs of the body of an organism in a proper manner to produce appropriate reaction to a stimulus is called coordination.
Stimulus
The change in the environment to which an organism responds and reacts is called stimulus.
Control and Coordination in animals
Control and coordination takes place in animals through the help of two main structures:
The nervous system is the part of an animal that coordinates its actions by transmitting signals to and from different parts of its body.
Functions of nervous system:
The working together of various organs of the body of an organism in a proper manner to produce appropriate reaction to a stimulus is called coordination.
Stimulus
The change in the environment to which an organism responds and reacts is called stimulus.
Control and Coordination in animals
Control and coordination takes place in animals through the help of two main structures:
- Nervous System
- Endocrine Glands
The nervous system is the part of an animal that coordinates its actions by transmitting signals to and from different parts of its body.
Functions of nervous system:
- Receive the information from environment by some organs.
- Transportation of information to brain through spinal cord and nerves.
- After analyzing the information, it reacts accordingly through muscles and glands.
Receptors
Receptors are group of cells present in sense organs which are sensitive to change in environment.
Neuron are the specialized cells which are combine to form nerves of the nervous system.
It is also called the structural and functional unit of life.
Receptors are group of cells present in sense organs which are sensitive to change in environment.
- Gustatory receptor: responsible for taste detection.
- Phono receptors: responsible for hearing.
- Olfactory receptors: responsible for smelling or smell detection.
- photo receptors: responsible for detecting light.
- Thermo receptors: responsible for feeling, touch of external stimuli.
Neuron are the specialized cells which are combine to form nerves of the nervous system.
It is also called the structural and functional unit of life.
