The loss of muscle function from disrupted nerve signals between the brain and muscles
What is Paralysis
each lasts 90-110 minutes; when dreams occur
What is a sleep cycle?
slight brain injury, no permanent brain damage
What is a concussion?
Contains primary motor cortex; controls most body movement. Found in the front of the brain.
What isFrontal Lobe
Main visceral control center of the body (internal organs), important to the homeostasis of the body. Regulates the body (temp, blood pressure, hunger/fullness, water balance/thrist, etc)
What is the Hypothalamus
Sensory loss, includes tingling, prickling, or numbness. Caused by nerve irritation or damage.
What is Parethesias
dementia, Alzheimer's, depression, PTSD, and anxiety
What are the risks of sleep deprivation?
Cerebrovascular Accident (CVA)
What is the medical name for a stroke?
Input from optic nerve, contains primary visual cortex. Located in the back of the brain.
What is Occipital Lobe
Shaped like an egg, acts as brains primary relay station(sensory input, motor signals, sports information). Key role in consciousness, sleep, attention, memory, etc.
What is the Thalamus
Progressive degenerative brain disease, mostly seen in elderly. Cause the brain to change by abnormal protein deposits and twisted fibers. Experience memory loss, irritability, confusion, and hallucinations.
What is Alzheimers disease
Rapid Eye Movement; happens 90 minutes after falling asleep; regenerates neurons
Nervous tissue destruction occurs, nervous tissue does not regenerates
What is a contusion?
Inputs are auditory, visual patterns (speech/face recognition), contains primary auditory cortex. Located on the sides.
What is Temporal Lobe
Aids with sleep-wake cycle, forms roof of 3rd ventricle, helps with CSF production. Most dorsal portion of the diencephalon.
What is the Epithalamus
Viral disease that attacks the nervous system. Causes paralysis, difficulty breathing, and sometimes death. There is no cure.
What is Poliomyelitis (Polio)
light sleep; easily awakened
What is the first sleep stage?
Swelling from an inflammatory response, may compress and kill brain tissue
What is a cerebral edema?
Inputs from multiple senses, outputs to frontal lobe (hand-eye coordination, attention). Located between frontal and occipital.
What is Parietal Lobe
Sits deep within the cerebral hemispheres and is surrounded by the cerebral hemispheres. Consists of 3 bilaterally symmetric structures (thalamus, hypothalamus, epithalamus)
What is Diencephalon
Progressive destruction of anterior horn motor neurons due to abnormal genes. It attacks motor neurons and leads to the lose of movement, speaking, swallowing, and breathing.
What is Amyotrophic Lateral Sclerosis (ALS)
Hard to arouse; feel groggy and confused when awoken; replenishes energy physically and mentally; non REM sleep
What are the elements of deep sleep?
"mini stroke"; same contralateral symptoms of a full stroke (paralysis, weakness, numbness, loss of vision, slurred speech, and mental contusion); symptoms disappear within a few minutes to 24 hours; precursor to full stroke
What is a TIA (transient ischemic attack)?
Contains 3 functional areas: Motor (control voluntary motor funcitions), Sensory (provide conscious awareness of sensation), and Association (any area that does not have "primary" in its name)
What is Cerebral Cortex
Not part of the diencephalon, masses of gray matter deep within cerebral hemispheres. Relay stations for motor impulses originating in cerebral cortex, aid in control of motor activities, related to diseases (Parkinson's and Huntington's)
What is Basal Ganglia
