A progressivley, degenerative disease that attacks the brain and its cognitive function. No known cure. Age 65-70 seems to be when it most frequently develops.
A disorder associated with misfiring or intereference of electrical impulses within the brain. Cause is unknow it is often the result of another condition such as a head injury, stroke, brain infection, or brain tumor
Inflamation oof the brain often caused by a viral infection. Patient can have/has fever, vomiting, photosentivity, stiff neck and back, confusion, drowsiness,clumsiness, and irritability.
(MS) is a chronic, potentially debilatating disease that effects the brain and spinal cord, and there is no cure. An autoimmune disease, in which the body attacks itself. Ab and WBC's to attack the myelin sheath surrounding the nerves in the brain and spinal cord.
Pertaining to little brain
(ex: Neuralgia) Pain
(ex Meningitis) Inflamation
Specialized nerve cells that make up nervous system tissue.
Nerve system chemicals that are released at the end of the knob- shaped axon. They travel across the synapse to the dendrites of the next nerve.
This is the outer layer membrane of the meininges surrounding the brain and the spinal cord to form a complete enclosure. The thickest and toughest of the meininges.
This is the middle layer of the meininges. This membrane is loosely attcked to the deepest of the meininges by weblike fibers,allowing space for the movment ofcerebrospinal fluid(CSF) between the two membranes.
The innermost layer around the brain is the pia mater; is attached to the nervous tissue of the brain and spinal cord and follows all the contours of these structures
Surrounds the brain and spinal cord. A colorless fluid produced as a filtrate of blood by the choroid plexuses within the ventricles of the brain. Normal adult would have between 120 and 150 ml ofCSF in circulation.
Are numerous ridges or convolutions on the surface of the cerebrum; this surface is known as the cerebrial cortex.
A deep groove in the brain is called a fissure, and a shallow groove is refered to as a suclus.
Part of the brainstem connects as well as the rest of the brain to the spinal cord.
Cavities that are located in the brain
A group of nerve fibers within the CNS is often reffered to as a tract. This is the largest nerve tract which joins the right and the left hemispheres of the brain.
Lies beneathe the thalamus and primarily regulates autonomic nervous activity associatied with behavior and emotional expression.
As part of the SNS (Somatic Nervous System) and there are 12 of them that are arranged symmetrically(12 to each side of the brain) and named for the function opr area in which they serve.
Part of the SNS( somatic nervous system) with 31 pairs of spinal nerves that are connceted to the spinal cord and named for the reigon of the vertebral colum where they exist. 8pairs of cervical and spinal nerves, 12 pairs of thoracic spinal nerves, 5 pairs of lumbar spinal nerves,5 pairsof sacral spinal nerves, and 1 pair of coccygeal spinal nerves
A knot or mass of nerve tissue outside the brian and spinal cord.
One of two primary branches from each spinal nerves. The dorsal rami (branches) carry motor and sensory fibers to the muscles and skin of the back and serve an area from the back of the head to the coccyx
One of two primary branches form each spinal nerves. The ventral rami, serving a much larger area,carry both motor and sensory fibers to t he muscles and organs of the body, including the arms, the legs, hands and feet.
An infection of the meninges that surround and protect the brain and spinal cord. Can be caused by a virus or a bacteria. If untreated the death rate is high.
A progressive disorder, with no cure, caused by degeneration of the nreve cells in parts of the brain that control movement.
Weakness or paralysis of the muscles that control expression on one side of the face.
Refers to a pain that runs along the sciatic nerve. O ften caused by inflammation dur to a pinched root of the sciatic nerve.
A cerebrovascular attack (CVA) death occurs to the brain tissue when the blood supply to a part of the brain is decreased, either by a clot or by hemorrage.
Damage, lessions, or a break in the spinal cord can result in paralysis of the body. Hemiplegia occurs when paralysis affect one side of the body.
Damage, lessions, or a break in the spinal cord can result in paralysis of the body. Paraplegia refers to paralysis from approximately the waist down
Damage, lessions,or a break in the spinal cord can result in paralysis of the body. Shoulders down
A recording and measuring of the electrical activity of the brain via an electroencephalograph.
A recording of the contraction of a skeletal muscle as a result of electrical stimulation; used in diagnosing disorders of nerves supplying muscles.
