13	Thick, outermost layer of the meninges surrounding and protecting the brain and spinal cord;...	dura mater
14	A collection of nerve cell bodies in the peripheral nervous system.	ganglion
15	Cells in the nervous system that do not carry impulses but are supportive and connective in...	glial cells
16	Sheets of nerve cells that produce elevation in the surface of the cerebral cortex; convolution.	gyrus
17	Portion of the brain beneath the thalamus; controls sleep, appetite, body temperature, and...	hypothalamus
