Answer:
He meant that the supporting cells form a insulating coat on the nerve fibre called myelin seath. The myelin Sheath act similar to the rubber coating of household wiring because it electrically insulates the nerve fibre and speeds of conduction of nerve impulse..
Explanation:
- The supporting cells of the nervous system are together called neuroglia or glial cells.
- Unlike neurons these cells can divide in the mature nervous system and do not conduct nerve impulse.
- Out of six types of glial cells, four are located in the central nervous system (CNS) and they are;astrocytes, oligodendrocytes, ependymal cells and microglia.
- The remaining two types are the part of Peripheral nervous system (PNS) and include Schwann cells and Sattelite cells.
- Among these , the oligodendrocytes of the CNS and Schwann cells of the PNS forms myelin sheath on the axons of the nerve cell that act similar to the rubber coating on the household wiring.
- The myelin sheath electrically insulates the axon of a neuron and increase the speed of conduction of nerve impulse.
Answer:
innate immunity : highly specialized defenses.
Explanation:
Immunity against infectious diseases are 2 types - innate immunity and acquired immunity. Innate immunity is the type of defense mechanism which is present at birth. This type of immunity does not depend upon the immunization. This type of immunity is not highly specific as acquired immunity. Innate immunity has no memory and response in first-rate towards the antigens. The phagocytic cells, dendritic cells are some cells of the innate immune system. This changes throughout the lifetime. Different species have different innate immunity. It means different species show different susceptibility to different diseases. e.g Rats are unsusceptible to Diphtheria while men, guinea pigs are highly susceptible to Diptheria.
