Question

What are the two types of cells in the nervous system?
A. Alveoli and veins
B. Alveoli and bronchioles
C. Neurons and nephrons
D. Neurons and glia

Answer 1

Hint: Nervous system is a type of complex system seen in higher vertebrates. The nervous system of the body is responsible for the transmission of electrical impulses in the whole body and transmitting and receiving information from each part of the body. The nervous system is composed of nerve cells and neuroglial cells.

Complete answer: Nervous system is a complex part of the animal body that is responsible for the coordination actions, sensory movements, and for transmitting and receiving information within the body. The nervous system is defined by the presence of its special type of cell called neurons. Neurons are also called nerve cells. They can be referred to as the functional unit of the nervous system. It is responsible for the transmission of electrical signals within the body. The transfer of the signal takes place from one neuron to another neuron at a place called synapses. Synapses occur between the axon of one neuron and the dendrite of another neuron. Glial cells are also part of the central nervous system and peripheral nervous system, but they do not produce electrical impulses. They are also called neuroglia or non-neural cells of the nervous system. Alveoli and bronchioles are a part of the respiratory system of the human body where exchanges of gases take place and veins belong to the blood circulatory system which carries the deoxygenated blood from various parts of the body to the heart via superior and inferior vena cava. Nephrons are specialized cell structures which belong to the excretory system of the human body. It is the fundamental unit of the excretory system where the filtering of blood takes place by absorbing the water, minerals, and soluble substances and excreting the rest of the waste in the form of urine.
So, option D is the correct answer from the above-provided options as both the cells belong to the nervous system.

Note: The nervous system of the human body is further classified as central nervous system (CNS), peripheral nervous system (PNS), and autonomic nervous system (ANS). The central nervous system is composed of the brain and spinal cord which regulates all the important activities of the body.
