Major divisions of the nervous system Central Nervous System (CNS) Peripheral Nervous System
What is included in the CNS? brain and spinal cord
What is included in the peripheral nervous system? cranial nerves, spinal nerves, plexuses
All cranial nerves carry impulses between the brain and the head and neck EXCEPT... cranial nerve X Vagus nerve
How many cranial nerve pairs are there? 12
How many spinal nerve pairs are there? 31
What is the name of a microscopic nerve cell? neuron
Examples of neurotransmitters.. Acetylcholine, norepinephrine, epinephrine(adrenaline), dopamine, serotonin and endorphins
The transfer of impulse across the synapse depends on the release of a chemical substance called... neurotransmitter
What is the largest part of the brain? cerebrum
What are sheets that nerve cells lie in, in the cerebrum? cerebral cortex
What are folds that the cerebral cortex are arranged in? gyri
What are grooves that separate the gyri? sulci
What are the halves called that the brain is divided into? cerebral hemispheres
What are the four lobes that each cerebral hemisphere is divided into? Frontal, parietal, occipital and temporal
What are some of the functions of the cerebrum? thought, judgement, memory, association and descrimination
What are the spaces called in the middle of the cerebrum? ventricles
What is the watery fluid that flows throughout the brain and around the spinal cord? cerebrospinal fluid (CSF)
What is the function of cerebrospinal fluid? to protect the brain and spinal cord from shock by acting as a cushion
What is the process of withdrawing CSF for diagnosis or relief of pressure on the brain? Lumbar puncture (LP)
What is the part of the brain that functions to coordinate voluntary movement and maintain posture and balance? cerebellum
Pons and medulla are part of the what? brainstem
What are centers of the medulla oblongata? respiratory, cardiac and vasomotor
Thinking, personality, sensations, movement, memory cerebrum
Relay station for sensory impulses; pain thalamus
Body temperature, sleep, appetite, emotions, controls pituitary gland hypothalamus
Coordination of voluntary movements and balance cerebellum
Connection of nerves (to eyes and face) pons
Nerve fibers cross over. Contains centers to regulate heart, blood vessels and respiratory system medulla oblongata
Brain disorder marked by gradual and progressive mental deterioration with personality changes and impairment of daily function. Alzheimer disease
Degenerative disorder of motor neurons in the spinal cord and brainstem amyotrophic lateral sclerosis (ALS)
Chronic brain disorder characterized by recurrent seizure activity epilepsy
Destruction of the myelin sheath on neurons in the CNS and it's replacement by plaques of sclerotic (hard) tissue multiple sclerosis
Autoimmune neuromuscular disorder characterized by weakness of voluntary muscles myasthenia gravis
paralysis of one side of the face Bell palsy
Degeneration of neurons in the basal ganglia, ocuring in later life and leading to tremors, weaknes in muscles, slowness in movement Parkinson disease
Involuntary, spasmodic, twitching movements, uncontrollable vocal sounds, inappropriate words Tourette syndrome
Disruption in the normal blood supply to the brain; stroke cerebrovascular accident (CVA) (thrombotic, emolic and hemorrhagic)
Paralysis of all four limbs quadraplegia
Paralysis of one side of the body hemiplegia
Weakness of one side of the body hemiparesis
Partial or total loss of the ability to communicate verbally or using written words aphasia
Failure of muscular coordination ataxia
Faint, temporary loss of conciousness syncope
ALS amytrophic lateral sclerosis
CVA cerebrovascular accident
TIA transient ischemic attack
LP lumbar puncture
