Neurons and nerve cells are the fundamental cells which make up the nervous system. The function of neurons is to send and receive messages or nerve impulses. A neuron is said to have central cell body and consists of two arms. Dendrites transport messages to the cell body; while the axon migrates messages away from the cell body. Impulses move from one neuron to another by going over small gaps called a synapse. There are 3 types of neurons which include: sensory, motor and association neuron. It has been mentioned that sensory neurons transport information about stimuli for example light, heat and chemicals in and out of the body to the central nervous system. Motor neurons provide instructions from the central nervous system to other parts of your body, for instance, muscles or glands. Association neurons join sensory and motor neurons.
It has been said that a neuron is an individual cell whilst a group of neurons create a nerve. Neurons contain nerve impulses as opposed to nerves which transmit information to many parts of the body. Nerves are located in the peripheral nervous system whereas neurons are located in the brain, spinal cord and peripheral nervous system. [1]
The synapse is the space in the middle of the presynaptic and post synaptic receptor. According to (Patrick 2013) Cholinergic receptors also called auto receptors exist at the terminus of the presynaptic neuron. These receptors serve to provide a way of local control over nerve transmission. Once…
