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 (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-3: -Neurons get nutrients from supportive cells called glial cells. There is two type of glial cells, neuroglial cells and the astroglial cells (astrocytes). These are the cells which are called as the supportive cells because these cells are responsible for providing nutrition to the neurons.

Detailed explanation-4: -Glial cells are essential for every aspect of normal neuronal development, synapse formation, and function in the central nervous system (CNS). Astrocytes secrete a variety of factors that regulate synaptic connectivity and circuit formation. Microglia also modulate synapse development through phagocytic activity.

Detailed explanation-5: -Astrocytes provide nutrients to neurons, maintain their extracellular environment, and provide structural support. Microglia scavenge pathogens and dead cells.
