nervous system

transmit impulses

enlarged structure of neuron

• brain
• spinal cord
• cranial nerves
• spinal nerves

• neurons
• neuroglia

carry impulses towards brain

carry impulses AWAY from brain/spinal cord

cells that support neurons and bind them

• cell body
• dendrites
• axons

consists of brain and spinal cord

largest organ in body

• largest and most upper of brain
• 2 hemispheres

• frontal
• parietal
• temporal
• occipital
• insula

folds or convolutions

• second largest structure of brain
• occupies posterior portion of skull
• includes movement, posture and balance
• aids in maintaining equilibrium and balance

composed of smaller structures including thalamus and hypothalamus

receives stimuli sensory and transmits them

regulates activities including impulses that regulate heartbeat, temp, fluid balance, and endocrine functions

• pathway for impulse conduction b/w brain and spinal cord
• controls respirations, BP, and heart rate

• midbrain
• medulla
• pons

protect brain and spinal cord

transmits sensory impulses from body to brain

• dura mater (outermost)
• arachnoid (middle covering
• pia mater (innermost)

originate in base of brain and emerge through openings

emerge from intervertebral spaces in spinal column

inflammation of nerve root associated with spinal column

functional abnormality of the cerebrum caused by disorders of blood vessels of brain

sudden changes in behavior or consciousness related to uncontrolled electrical brain activity

progressive neurological disorder, effecting portion of brain that controls movement

progressive, degenerate disease of central nervous system- inflammation, hardening, loss of myelin

progressive neurological disorder that causes memory loss and mental deterioration

severe loss of contact with reality

caused by emotional experience in past

abnormal mood

eating disorder

excessive worry

impulsiveness, cant remain focused

unusual shifts in mood

fear

originate in brain tissue

partial or complete loss of sensation

prevent uncontrolled neuron activity

control tremors

treat psychosis, paranoia - alters chemicals in brain

treats depression- increases neurotransmitter

depress CNS functions - relieve agitation, anxiousness, restlessness,

reduce impulsiveness increases neurotransmitters
