Central Nervous system (CNS) contains:
brain & spinal cord
Peripheral nervous system (PNS) contains:
cranial nerves, spinal nerves, plexuses, & peripheral nerves throughout the body
10th Nerve, carries messages to and from the neck, chest, and abdomen
vagus nerve
nerve fibers cross over, left to right and right to left; contains centers to regulate heart, blood vessels, and respiratory system
medulla oblongata
body temperature, sleep, appetite, emotions; control of the pituitary gland
hypothalmus
congenital defects in the lumbar spinal column caused by imperfect union of vertebral parts (neural tube defect)
spina bifida
brain disease and dementia occurring with AIDS
human immunodeficiency virus (HIV) encephalopathy
viral infection affecting peripheral nerves
herpes zoster (shingles)
X-ray imaging of the arterial blood vessels in the brain after injection of contrast material
cerebral angiography
Computerized x-ray technique that generates multiple images of the brain and spinal cord
computed tomography (CT) of the brain
Cerebral Concussion
TRAUMATIC BRAIN INJURY
Cerebral Contusion
BRUISING OF BRAIN TISSUE
destruction of the myelin sheath on neurons in the CNS and its replacement by plaques of sclerotic tissue
multiple sclerosis (MS)
autoimmune neuromuscular disorder characterized by weakness of voluntary muscles
myasthenia gravis (MG)
degenerative disorder of motor neurons in the spinal cord and brainstem
Amyotrophic lateral sclerosis (ALS)
connection of nerve and nerve fiber pathways, including those to the eyes and face
Pons and Midbrain
coordination of voluntary movements and balance
Cerebellum
Relay station (“triage center”) for sensory impulses, control of awareness and consciousness
Thalamus
Thinking, personality, sensations, movements, memory
Cerebrum
Sympathetic Nerves
stimulate the body in times of stress and crisis
Parasympathetic Nerves
nerves balance the sympathetic system [SLOW HEART RATE & LOWER BLOOD PRESSURE]
small clusters of nerve cell bodies
ganglia
maintain the health of the nervous system
glia cells
Acetylcholine is a
NEUROTRANSMITTER
part of the nerve cell that first receives nerve impulses
Dendrite
protective separation between the blood and brain cells (protects brain)
blood-brain barrier
thick, outermost layer of the meninges
dura mater
thin, delicate inner membrane of the meninges
pia mater
essential, distinguishing tissue of any organ or system [for the nervous system, neurons and nerves that carry impulses]
parenchyma
connective and supporting tissue of an organ
stroma
space through which a nervous impulse travels between nerve cells or between nerve and muscle or glandular cells
synapse
depression or groove in the surface of the cerebral cortex; fissure
sulcus
large, interlacing network of nerves
plexus
three protective membranes that surround the brain and spinal cord
meninges
carries messages away from the brain and spinal cord
efferent nerve
glial cell that lines the membranes within the brain and spinal cord; helps from cerebrospinal fluid
ependymal cell
