Living organisms respond to stimuli in the form of body movements. B) Coordination:- For a proper response to a stimulus many organs in the body should work together. The working together of various organs in an organism to produce a proper response to a stimulus is called coordination. I) In animals control and co ordination is done by the nervous system and endocrine system. Ii) In plants control and co ordination is done by chemical substances called plant hormones or phytohormones. 1a) Stimuli:- © Galaxysite.weebly.com - All Rights Reserved Page 3.

Olfactory receptors in the nose to detect smell. Gustatory receptors in the tongue to detect taste. Tangoreceptors in the skin to detect touch. B) Effectors:- are the muscles and glands which respond to the information from the brain and spinal cord through the motor nerves. C) Sensory nerves:- are nerves which carry information from the receptors (sense organs) to the brain and spinal cord. D) Motor nerves:- are nerves which carry information from the brain and spinal cord to the effectors (muscles and glands). 2) Coordination in animals:- © Galaxysite.weebly.com - All Rights Reserved Page 4.

The nervous system consists of the brain, spinal cord and nerves. A) Receptors:- are the sense organs which receive the stimuli and pass the message to the brain or spinal cord through the sensory nerves. Eg:- Photoreceptors in the eyes to detect light. Phonoreceptors in the ears to detect sound. Olfactory receptors in the nose to detect smell. Gustatory receptors in the tongue to detect taste. Tangoreceptors in the skin to detect touch.
