The human brain is in many ways still a mystery to scientists. Recent studies have revealed interesting new insights into brain development, including what, if any, gender differences exist between the male and female brain.
Essay on Human Brain: The nervous system of man and other group of vertebrates is divided into three main parts: Central nervous system CNS comprising brain and spinal cord. Peripheral nervous system PNS consisting of cranial and spinal nerves.

An adult human brain weighs about gms. In a new born baby it is about gms and becomes double after one year and has a volume of about c.
It is enclosed in a bony case called cranium which protects brain against external injury. The brain is being surrounded by three membranes called meninges sing-meninx. At two places the piameter fuses with the thin, dorsal surface of the brain to form choroid plexus.
The meninges protect the brain from external shock.
The space between duramater and arachnoid is the subdural space and the space between arachnoid and piamater is known as subarachnoid space Fig.
These spaces surrounding the brain as well as the cavities within the brain are filled with a lymphatic fluid, called cerebrospinal fluid CSF. The cerebrospinal fluid is also present within the spinal cord.
The cerebrospinal fluid protects the central nervous system from external shock; helps in exchange of nutrients and waste products between the nervous tissue and blood and maintains a constant pressure in and around the brain.
The brain is formed of two types of nervous tissue, Grey matter on the outer side and White matter on the inner side. The former is made of non-medullated nerve cells whereas the latter is formed of medullated nerve cells.
The brain or encephalon is a white, bilaterally symmetrical structure. It is divided into three main parts: Mid brain or Mesencephalon 3. Hind brain or Rhombencephalon Fore Brain: It is the anterior part of the brain and largest among the three parts.Welcome to the Human Brain Project.
