Divison of nervous system

• The nervous system is divided into sections: the central nervous system and the peripheral nervous system
• The central nervous system (CNS) consists of the brain and spinal cord. Its main role is to control behaviour and psychological processes as well as the regulation of physiological processes.
• The brain is responsible for perception, auditory information (temporal lobe), motor control and processing sensory information (parietal lobe)
• The spinal cord connects the brain to the peripheral nervous system, relaying information between the brain and the body. The spinal cord is responsible for some unconscious movements such as reflexes.
• The peripheral nervous system (PNS) consists of all nerves outside of the CNS. It has two divisions: somatic and autonomic.
• Autonomic division - controls involuntary functions such as heart rate, digestion and breathing. It can be further subdivided into sympathetic and parasympathetic systems which have opposing effects on bodily function.
• Somatic division - controls voluntary movement and conscious sensation. Sensory neurons carry messages from receptors to the CNS and motor neurons carry messages from the CNS to effector organs.
• ANS has purely motor pathways, controls internal organs and glands, and control involuntary movement.
• SNS has sensory and motor pathways, controls skeletal muscles and is under conscious control.
• ANS: is split into two further system: Sympathetic and Parasympathetic
• Sympathetic mobilises your body for action.
• Parasympathetic conserves energy and maintains a quiet body state
