Neural Control and Coordination – Notes

Neural System
Coordination between organ systems and the functions of the organs is crucial to maintain a physiological balance, called homeostasis.
The neural system and the endocrine system maintain homeostasis in our body.
Neurons are called the structural and functional units of the neural system.
The human neural system is divided into the central neural system (CNS) and the peripheral neural system (PNS).
The brain and spinal cord from the central neural system, and the cranial and spiral nerves form the peripheral neural system.
The peripheral neural system can be divided into somatic neural system and the autonomic neural system.
The autonomic neural system is further classified into the sympathetic neural system and the parasympathetic neural system.
A neuron is a branched nerve cell and is the longest cell in the body.

Generation and Conduction of Nerve Impulse
The nerve impulse is the sum of mechanical, chemical and electrical disturbances created by s stimulus in a neuron.
