Myelin sheath is produced by
- Astrocytes and Schwann cells
- Oligodendrocytes and Osteoclasts
- Osteoclasts and Astrocytes
- Schwann cells and Oligodendrocytes
The Correct Option is D
Solution and Explanation
Myelin sheath is an extended and modified plasma membrane that is wrapped around the nerve axon in a spiral mode. Myelin membranes originate from and are a part of the Schwann cells in the peripheral nervous system (PNS) and the oligodendroglial cells in central nervous system (CNS).
Osteoclasts are a large multinucleate bone cell that absorbs bone tissue during growth and healing. Astrocytes are star-shaped glial cells of the central nervous system.
Thus, the correct answer is D Schwann cells and Oligodendrocytes.

Neural Control and Coordination
Neural System:
Neurons are the most specialised cells in the nervous system of all animals, and they are responsible for detecting, accepting, and conveying numerous types of motives. The neurological system of low-spinal animals like Hydra is incredibly simple, consisting of a network of neurons. When the brain of an insect comprises a vast number of ganglia and neural tissues, it is optimally structured.
Coordination System:
Coordination is the process by which two or more organs work together to accomplish each other's duties. Increased muscle activity increases the supply of oxygen and the demand for energy while we exercise. When we cease exercising, our nerves, heart, lungs, and kidneys all return to normal. As a result, all of the organs' functions are properly integrated in order to conduct the exercise and supply the appropriate conditions while exercising. Similarly, in the human body, the neurological and endocrine systems work together to coordinate all of the organ activities.
