Neurons and Neuroglia exam fully solved & updated.
Neuroglia support, insulate and protect the neurons Astrocytes compose half of all nervous tissue. Star shaped; Cling to neurons and bring them blood supply Microglia spider-like phagocytes that dispose of cellular debris and bacteria Ependymal Cells line the CNS cavities. Contain cilia that move CSF around. Oligodendrocytes produce the fatty coverings around neurons called myelin sheaths, that insulate the neurons. Schwann Cells form myelin sheaths around neurons. Ex) oligodendrocytes Satellite Cells protect, nourish and cushion neurons Ex) astrocytes, microglia and ependymal cells Neurons The cells of the nervous system; They transmit impulses from one part of the body to another. Cell Body metabolic center of the cell; contains the nucleus and organelles. Axon an extension of the cell body that carries impulses away from the cell body. Axon Terminal the end of an axon; where it meets a dendrite, muscle or gland Dendrite an extension of the cell body that carries impulses towards the cell body. Myelin Sheath the fatty insulation that surrounds and protects an axon. Synapse the gap between the axon termial and the muscle, gland, organ or neuron that it meets. Interneurons neurons that reside within the spinal cord and connect sensory and motor neurons to each other. Neuroglia Support insulate and protect cells Neuron Demonstrate irritability and conductivity, and thus transmit electrical messages from one are of the body to another area Neuron Release neurotransmitters
