TCA - Nervous System Payday #1

Nervous sytem subdivision that is composed of the brain and spinal cord

Subdivision of the PNS that controls voluntary activities such as the activation of skeletal muscles.

Nervous system subdivision that is composed of the cranial and spinal nerves and ganglia.

Subdivision of the PNS that regulates the activity of the heart and smooth muscles and of glands; also called the involuntary nervous system.

A major subdivision of the nervous system that interprets incoming information and issues outgoing "orders"

A major subdivision of the nervous system that serves as the communication lines, linking all parts of the body to the CNS.

Supporting cells found in the CNS are called neuroglia.

Neurons are mitotic and therefore are responsible for most brain neoplasms (tumors)

Schwann cells and satellite cells are found only in the PNS.

Ependymal cells show irritability and conductivity.

Almost 50% of the mass of the brain is neuroglial cells.

In the CNS, oligodendrites engulf invading microorganisms and dead neural tissue.

Ependymal cells line the central cavities of the brain and spinal cord, where they form a fairly permeable barrier between the cerebral spinal fluid and the fluid surrounding the cells of the CNS.

Oligodendrocytes wrap their cytoplasmic extensions around thick neurons fibers in the CNS.

The bulb-like ends of the axons of neurons, synapse with capillaries.

Relative to neuron anatomy, match the descriptors to the appropriate anatomical term.
