Hey friend here is your answer....


The brain lies within the skull, or the cranium. It is covered by three membranous layers called meninges . Between the meninges and inside the brain is a fluid called cerebrospinal fluid (CSF) that cushions the brain against shocks . It also helps distribute nutrients and other chemicals to the neurons of the brain and collects waste from them . It provides the neurons some protection from infection .

The brain is divided into three parts the forebrain , midbrain and hindbrain .

The Forebrain :

This is the anterior part of the brain . The cerebrum forms the largest part of the forebrain, or rather of the entire brain . it is divided into two halves - the right and left cerebral hemispheres . The cerebral hemispheres are shaped somewhat like Kidneys, and or partially separated from each other by a deep groove . their outer surface is full of folds , which increase the surface area and help accommodate the maximum number of neurons . The cell bodies of most of the neurons are located in the upper layers of the cerebral hemispheres, giving these layers a greyish appearance . So, the cell bodies are called grey matter . The axons mostly myelinated of these neurons form bundles that appear white, and are thus called white matter . White matter is mostly found in the deeper  parts of the cerebrum . The interior of the cerebrum has interconnected cavities called ventricles that are filled with cerebrospinal fluid.

The cerebrum is the centre of Intelligence . Different areas of the cerebrum or concerned with learning, memory emotion and reasoning other areas co-ordinate our voluntary activities and make us feel sensation like pain and heat and also control speech and the Census of touch, smell , sight , hearing and taste.  

The hypothalamus a small area of the fore brain is linked to the pituitary gland it controls the endocrine system it also controls many emotional reactions like fear and anger .

The midbrain :

The small region connects the fore brain with the hind brain and spinal cord. It also controls the eye adjustments we need to make in order to see .

The Hindbrain :

This is the posterior part of the brain and is located below the forebrain . It consists of the cerebellum, pons and medulla oblongata . the cerebellum smaller than the cerebrum and is located below it towards the back of the skull . the surface of the cerebellum as a large number of thinely spaced parallel grooves, unlike the irregular folds of the cerebrum . the cerebellum, too is made up of a large number of neurons .  The upper layer ,  while the white matter is buried deeper within the structure . A fourth ventricle, filled with cerebrospinal fluid, lies between the cerebellum and the upper part of the medulla oblongata it is connected to the third ventricle , through a thin duct.  The cerebellum coordinates our movements , both voluntary and involuntary . It maintains the bodies posture and balance, and helps us learn new movements .

the Pons lies just about the  medula oblongata . It  relays information from the fore brain to the cerebellum . It also helps control functions such as sleep, breathing, swallowing, bladder function, hearing, taste, eye moment, facial expressions,  facial sensation, balance and posture .

The medulla oblongata lies in front of the cerebellum, at a slightly lower level, and connects to the spinal cord . It controls involuntary actions, such as Heartbeat breathing, sneezing, coughing, swallowing, vomiting , movements of the alimentary canal and secretion by glands . The midbrain, pons and medulla oblongata together make up the brain stem .
