Question

4. Draw and explain the "Nervous Tissues".​

Answer 1

Answer:

Nervous or the nerve tissue is the main tissue of our nervous system. It monitors and regulates the functions of the body. Nervous tissue consists of two cells: nerve cells or neurons and glial cells, which helps transmit nerve impulses and also provides nutrients to neurons.

Answer 2

Nervous Tissues

• Nerve cells play a crucial role in the neurological system. Nerve cells create and convey impulses in nervous tissues.

• Nervous tissues are found in the brain, spinal cord, and nerve. The nervous system drives muscular contraction, produces environmental awareness, and is involved in emotion, memories, and thinking.

• Dendrites, cell body, and one axon are the three main components of a neuron. The huge soma body is surrounded by dendrites.
• All of those are short projections or branched structures which receive electrical and chemical signaling (neurotransmitters) and affect the cell's potential. 

• The axon is the portion of the neurons that transports the action potential away from the cell body. On the outside, it has a protective sheath. The nodes of Ranvier are a space between both the myelin sheath.
• The lamp structures known as axon terminals were divided from dendrites by such a gap known as the synaptic cleft. Synapses are where neurotransmitters were released and impulses are sent from one neuron to the next.
