The most impressive thing about Neurons is that they carry messages very quickly, this message travels at about +100 m.s-1.
They also consists of long, thin fibres of cytoplasm which assist them to transport the message, and these kinds of fibres are called Nerve fibres
There are two kinds of fibres the longer kind is known as AXONS, and the shorter are called DENDRONS.
|THE GENERAL FUNCTIONS OF THE NERVOUS SYSTEM|
|1. Detection of sensory stimuli
2. Control behavior
3. The processing of information
4. Excitement etc.
The components of the Nervous system which permits the body to communicate with the Environment are MOTOR, INTEGRATION and SENSORY.
|MOTOR||- It conducts signals from the processing centre which is the central nervous system to the effector cells|
|SENSORY||- Is the conduction of signals from sensory receptors to integration centres in the nervous system.|
|INTEGRATION||- Is a neuron, which is responsible for the process of adding up electrical signals from sensory inputs or other nerve cells to determine the overall electrical activity of the nerve cell.|
