Neurons in Action
Neurones are cells within the nervous system that possess the ability to receive and send information. A neuron consist of three parts viz - a - viz; the dendrite, which is responsible for receiving signals/imput from a nearby neurons, it is highly branched and looks like a tangled bush.
The second component of a neuron is the CELL BODY, the cell body housed the nucleus of the neuron, and every element that the neuron needs for its metabolic activities and finally the third component of a neuron is the AXON; this is the part of the neuron that relay the information(signal/input) coming to the neuron to the other neuron through synaptic transmission(neurotransmitters).
There are three types of neurons, these are;
sensory neurons/afferent neurons; this type of neuron are the one responsible for carrying sensory inputs/signal inwardly toward the central nervous system.
motor/efferent neuron: on the other hand, this type of neuron carry information from the central nervous system to their effector muscle. most often, this neurons have long axon and are myelinated for fast and effective communication.
inter neurons; this neuron is responsible for transmiting information from one neuron to another, they are neither afferent nor efferent.
