Cells of the Nervous System

What cells produce myelin in the PNS?

• astrocyte

• Schwann

• satellite

• microglia

What cells produce myelin in the CNS?

• microglia

• ependymal

• ogliodendrocytes

• satellite

What's an afferent (sensory) neuron?

• nerve fibers that bring sensory info from outside world into brain

• conducting cells that carry information from the CNS to muscles/organs

• Don Knotts

• circulates hormones and essential substances to body parts

What is an efferent neuron?

• conducting cells that carry information from the CNS to muscles/organs

• a neuron that conveys impulses from one neuron to another

• it accepts oxygen and transports it to different locations

• the fluid that cushions the spinal cord

What is an interneuron?

• a neuron that conveys impulses from one neuron to another

• a two-way respiratory carrier

• Mrs. DiGiacomo's best friend

• thin nerve fibers that carry nerve impulses away from a neuron (nerve cell) to another neuron

What's an axon?

• long fiber that extends from soma and conducts impulses away from it

• a cell that receives input from other neurons, processing and carrying those signals to the soma

• regulate brain development, maintenance of neuronal networks, and injury repair

• an ciliated-epithelial glial cells that develops from radial glia along the surface of the ventricles of the brain and the spinal canal

What contains the nucleus and is the metabolic center of the cell?

• soma

• synapse

• axon

• dendrite

What is a slender fiber that conducts impulses toward the soma?

• Dendrite

• Axon

• Node of Ranvier

• Soma

What is the junction of two neurons?

• synapse

• synaptic cleft

• myelin sheath

• neuroglia

What is the space between the axon terminal of one neuron and the dendrites of another neuron?

• synaptic cleft

• myelin sheath

• Sir Schwann

• soma
