AP PSYCHOLOGY

Detailed explanation-1: -Glial cells help support, connect, and protect the neurons of the central and peripheral nervous systems. They come in many shapes, sizes, and types, each performing specialized functions. In the CNS, glial cells regulate neurotransmission and help form the blood-brain barrier.

Detailed explanation-2: -Glial cells support neurons and maintain their environment. Glial cells of the (a) central nervous system include oligodendrocytes, astrocytes, ependymal cells, and microglial cells. Oligodendrocytes form the myelin sheath around axons.

Detailed explanation-3: -Glial (Neuroglial) cells do not conduct nerve impulses, but, instead, support, nourish, and protect the neurons. Glial cells are far more numerous than neurons and, unlike neurons, are capable of mitosis.

Detailed explanation-4: -In general, neuroglia function to support, protect, and nourish neurons. The main parts of a neuron include the cell body, dendrites, and axon . The cell body contains the nucleus . Dendrites receive nerve impulses from other cells, and the axon transmits nerve impulses to other cells at axon terminals.

Detailed explanation-5: -It appears that glial cells called astrocytes-so-called because they are shaped similarly to stars-play an active role in memory and learning. This is according to a new study from the University of California (UC), Riverside.
