Overview

Neural control and co-ordination is the system that helps different parts of the body work together quickly and in a controlled way. It allows the body to receive stimuli, process information, and produce suitable responses. The nervous system is made of specialised neurons that detect, receive, and

Key Concepts

Co

Co-ordination is the process through which two or more organs interact and complement the functions of one another. The nervous system provides the fa

The neural system of animals

The neural system of animals is made of highly specialised cells called neurons. These cells detect, receive, and transmit different kinds of stimuli.

The central nervous system includes

The central nervous system includes the brain and spinal cord. It is the main site of information processing and control. It is protected by the skull

The human brain weighs about 1

The human brain weighs about 1,350 g and contains about 1,000 billion neurons and neuroglia. It is divided into forebrain, midbrain, and hindbrain. Th

The midbrain lies between the forebrain

The midbrain lies between the forebrain and hindbrain and contains cerebral peduncles and corpora quadrigemina. The hindbrain includes the cerebellum,
