To identify:
The structure of a neuron with reference to the Figure 14A “Structure of a neuron” given in the textbook.
Concept introduction:
Nervous system controls and coordinates the functions of body. Nervous tissue has two types of cells: neurons and glial cells. Neuron is the structural and functional unit of the nervous system.
The neuron body consists of nucleus, dendrite: short extension, which receives signals from the afferent neuron, and axon which conduct nerve impulses. The axon has a small swelling at their end which is called as axon terminal. This terminal lies very close to the dendrite of next neuron. This close proximity of each neuron is called as synapse and the small gap between the synapses is called as synaptic cleft.
