Document Summary
The brain has many functions and is the most cellularly diverse part of the body, some basic brain functions include: thermoregulation, eating/drinking, circadian rhythms, autonomic function, sexual function, coordinated skeletal control, vital reflexes. The brain must be viewed as an integral part of the nervous system. The brains function in the pns is to relay information from the periphery environment to the cns and relay motor output to muscles. When acting in the cns it is used to process information from the pns to produce an appropriate response. The nervous system can be divided into sections. The central nervous system is enclosed by 3 membranes (meninges), dura (outer), The brain can be divided into 7 sections: spinal cord, medulla (oblongata, pons, midbrain, cerebellum, diencephalon, telencephalon. The spinal cord receives and processes sensory information which is subsequently relayed towards the brain. It controls movement of the limbs and trunk via motor output.
