Chapter 8: Problem 6

In the CNS, glycogen is found only in a. oligodendrocyte b. microglia c. astrocyte d. neuron e. all the above

Short Answer

Expert verified
Answer: Astrocyte

Step by step solution

01

Understanding the CNS cell types

In the central nervous system, there are four main types of glial cells: oligodendrocytes, microglia, astrocytes, and ependymal cells. Neurons are also present in the CNS, functioning as the main information processing cells. Briefly, the functions of each cell type are as follows: - Oligodendrocyte: Produces the myelin sheath, aiding in the insulation of and the speed of electrical impulses in neurons. - Microglia: Acts as the immune cell of the CNS, identifying and destroying pathogens or damaged tissue. - Astrocyte: Supports neurons by regulating neurotransmitters, maintaining the blood-brain barrier, and providing nutrients to neurons. - Neuron: Transmits and processes information within the CNS.
02

Identifying the cell type with glycogen

Among these cell types, astrocytes are known to store glycogen. This glycogen is primarily used as an energy source to support the functions of neurons and maintain homeostasis within the CNS.
03

Selecting the correct answer

Knowing that only astrocytes store glycogen in the CNS, we can choose the correct answer in the multiple-choice options: a. oligodendrocyte b. microglia c. astrocyte d. neuron e. all the above Therefore, the correct answer to this exercise is C.astrocyte.
