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
develops & maintains female sex characeristics
hypophysectomy
removal of pituitary gland
ADH
antidiruetic hormone
PTH
parathyroid hormone
GH
growth hormone
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)?
