Cerebellum

Part of brain responsible for coordinating muscle movements & maintaining balance

Myoneural

Pertaining to muscles and nerves

Dendrite

Part of nerve cell that recieves nervous impulse

synapse

space through a nervous impulse is transmitted from one neuron to another or from a neuron to another cell such as a muscle or gland cell

paresthesia

abnormal sensation of tingling or prickling

quadriplegia

paralysis of four extremities

anesthesia

condition of no nervous sensation

adenohypophysis

anterior lobe of pituiraty gland

potassium

Kal/i- combining form

epinephrine

sympathomimetic; elevates heart rate, blood pressure

testosterone

promotes growth & maintenance of male sex

ADH

Stimulates water reabsorption by Kidney tubules, decreases urine

Thyroxine

increases metabolism in body cells

Parathyroid Hormone

Raises blood calcium

Aldosterone

increases reabsorption of sodum by kidney tubules

Define ACTH

Stimulates secretion of hormones from adrenal cortex

ACTH

Adrenal Cortropic Thyroid Hormone

Cortisol

Increases blood sugar

Insulin

Helps transport glucose to cells & decreases blood sugar

estradoil

First layer of meninges

Dura Mater

Second layer of meninges

Arachnoid Membrane

Third layer of meninges

Pia Mater

Dura Mater

Thick, outermost layer of the meninges surrounding and protecting the brain and spinal cord (latin for hard mother)

Arachnoid Membrand

Middle layer of the three membranes that surround the brain and spinal cord

meninges

three layers of connective tissue membranes that surround the brain and spinal cord

Cauda Equina

collection of spinal nerves below the end of the spinal cord

brainstem

lower portion of the brain that connects the cerebrum with the spinal cord. The pons ad medulla oblongata are part of the brainstem.

axon

microscopic fiber that carries the nervous impulse along a nerve cell

dendrite

microscopic branching fiber of a nerve cell that is the first part to receive the nervous impulse.

ependymal cell

a glial cell that lines membranes within the brain and spinal cord and helps form cerebrospinal fluid

ganglion

collection of nerve cell bodies in the peripheral nervous system.

CNS

Central nervous system; brain and spinal cord

gyrus

sheet of nerve cells that produces a round fold on the surface of the cerebral cortex; convolution

nerve

macroscopic cordlike collection of fibers (axons and dendrites) that carry electrical impulses

parasympathetic nerves

involuntary, autonomic nerves that regulate normal body functions such as heart rate, breathing, and muscles of gastrointestinal tract

pons

part of the brain anterior to the cerebellum and between the medulla and the rest of the midbrain. It is a bridge connecting various parts of the brain

stroma

connective and supporting tissue of an organ. glial cells are the stromal tissue of the brain.

thalamus

main relay center of the brain. conducts impulses between spinal cord and cerebrum

vagus nerve

tenth cranial nerve; its branches reach to the larynx, trachea, bronci, lungs, aorta, esohagus, and stomach.

astrocytoma

What CNS tumor cells stain positive for glial fibrillary acidic protein (GFAP)?
