Question

Show the pathway of electric impulse.
A. Dendrite → Cell Body → Axon → to its end
B. Cell body → Dendrite → Axon → to its end
C. Axon → Cell body → Dendrite → to its end
D. Dendrite → Axon → Cell body → to its end

Answer 1

Hint: Human body has specialized cells called neurons which respond by sending electric impulses. This whole process is also known as a reflex arc.

Complete answer:
Whenever we touch any hot object our body quickly responds to it with the help of the nervous system. The nervous system is a part of the animal body that coordinates its behavior and transmits signals to various parts of the body. There are two main types of nervous systems: the peripheral nervous system (PNS) and the central nervous system (CNS).
The peripheral nervous system (PNS) contains nerves that are long fibers that connect CNS to all parts of the body along with other important components. The spinal cord and brain are the parts of the Central nervous system. The nervous system has a specialized cell called a neuron or nerve cell that transfers signals in the form of an electrochemical wave. Neurons have a cell body, axon, and dendrite which helps them send and receive a chemical signal.
A neuron is stimulated when it receives a signal at dendrites which are passed through the cell body towards the axon of one cell that transfers this signal to the dendrite of another neuron cell and finally the response is generated.
Hence, the correct option will be option A.

Note: Neurons can be of different shapes and sizes. In some long neurons, the axon is covered with a thin layer of myelin that helps in the transfer of signals to the axon. Depending upon the position in the body, neurons have different shapes for example sensory neurons have dendrites on both the end connected with a long axon that has a cell body within. Motor neurons have a dendritic on one end and a cell body on the other with an axon in the middle.
