structures of neuron

. Axons with such a covering are called as myelinated or medullated and those without are called as non-myelinated or non-medullated. The function of myelin sheath is to increase the speed of conduction of the impulse. There is another cellular covering surrounding the axon, called neurilemma (or s..

Units of Nervous System - The units of nervous system are specialised cells called the neurons . The general structure of a neuron is as follows: Neuron Around the cell body are short sensory projections called the dendrons. The fine branches of dendrons are ..

The neurons present in the brain that connect the sensory and the motor neurons are called interneurons or connecting neurons Interneur..

Cells vary in shape and size. They may be oval, spherical, rectangular, polygonal, spindle shaped, star shaped, rod-shaped or totally irregular like the nerve cell. The diversity in cells is in accordance with the role or function it has to perform as part of the tissue or organ system. In general,..

Nature, Occurrence and Function Neuron The brain, spinal cord and nerves are all composed of nervous tissue. Each nerve cell is called a neuron. These are highly specialized cells. They have the ability to receive stimulus from within or outside and send impulses to different pa..

Nervous Tissue - It is a highly specialised animal tissue that exhibits two unique properties irritability (capacity to respond to the stimulus) and conductivity (capacity to transfer the response from one region to another). Nervous tissue is of ectodermal origin. The nervous tissue is composed of..
