Nervous system Flashcards
What are the structures of the nervous system?
Central nervous system
Peripheral nervous system
What are the three parts of the brain and describe each part?
Cerebrum-thought and intelligence
Cerebellum -regulates and coordinates body movement
Brainstem -connect cerebrum to spinal cord
What are Meninges?
The layers of connective tissue covering and protecting the brain and spinal cord
What is cerebrospinal fluid?
A fluid circulating around the brain and spinal cord protecting the central nervous system system
What is the function of the nervous system?
Coordinates and control all bodies activities
Organize in store information
Detect changes and feel sensations
Initiate responses to changes
What are the central nervous system functions?
Cerebrum-controls body movement, left hemisphere, right side body, right hemisphere left side body
Cerebral cortex -controls functioning of reasoning, memory and speech
Cerebellum -coordinates body movement
What are the functions of the peripheral nervous system system?
Autonomic nervous system-
controls involuntary muscles control certain bodily functions
systems are sped up by sympathetic and slow down by the parasympathetic nervous system
What are the sense organs?
Eyes ears, nose, tongue
What are the Changes with age in the nervous system?
Decreased blood supply to the brain
Loss of nerve cells
Visual changes and losses
Hearing changes
What is Parkinson’s disease?
A neurological disorder in which certain parts of the brain are gradually destroyed cause is unknown and there’s no cure for Parkinson’s
Rigid muscles, tremor, and shaking muscle weakness
What is Multiple sclerosis?
Chronic degenerative disease of the nervous system. nerve impulses cannot travel to and from the brain in a normal manner no known cause or known cure
What are seizures?
A brief disturbance in the brains, normal electrical functioning. Occurs when a group of brain cells overreact disturbing the balance within the brain..
Causes may be brain injuries
What is a cerebral vascular accident?
Stroke. Results from a rupture or blockage of a blood vessel in the brain depriving parts of the brain of its blood supply.
What are specific characteristics to left brain damage?
Right side paralysis
Language and speech challenges (aphasia)
Most have trouble reading and writing
Tend to be slow, cautious and disorganized
What are specific characteristics to right brain damage?
Left side paralysis
Spatial perceptual challenges
Difficulty with judging distance size and position
Tend to be impulsive, fast and impatient
