Which part of our body store information and receive sensory impulse from various parts of our body
Answers
Answer:
Cerebrum
Explanation:
Which is present in our brain to store information
Answer:
The nervous system helps in controlling and coordinating various activities of the human body. The three types of nerves, cranial nerves, spinal nerves and visceral nerves run through the body and help in sending and receiving messages in the form of electrical impulses.

Control and Coordination in Humans
The nervous system helps in controlling and coordinating various activities of the human body. The three types of nerves, cranial nerves, spinal nerves and visceral nerves run through the body and help in sending and receiving messages in the form of electrical impulses.
The control and coordination in human beings take place through nervous system and hormonal system which is called endocrine system.
The five sense organs in our body, eyes, ears, nose, tongue and skin are called receptors. This is because they receive information from the environment around us. Therefore, a receptor is a group of cells in sense organ which is sensitive to a particular type of stimulus like light, sound, smell, taste, heat, etc.
All the receptors send message in the form of electrical impulses to spinal cord and brain through sensory nerves. Another type of nerves called motor nerves then transmits response from brain and spinal cord to effectors. An effector is a part of the body which responds to a stimulus according to the instructions sent from the nervous system. The muscles and glands are effectors of the body.
Human Nervous System
Nervous system coordinates the activities of our body. It controls all our behaviour, thinking and actions. It is through nervous system only that all other systems of our body work. It passes information from one internal system to another. For example, when we put food in mouth, it causes release of saliva from the salivary glands.
The Unit of Nervous System: Neurons
The cells that make up the nervous system are called neurons. Neuron is the largest cell in the body. The structure of neuron is such that it can carry messages in the body quickly. These messages are in the form of electrical impulses or nerve impulses. There are three components of neurons. They are:
i) Cell body
ii) Dendrites
iii) Axon
hey pls mark as the brainliest answer....
