HOSA behavioral health knowledge
Central Nervous system (CNS) - -includes thirst; directs ANS and endocrine system
the brain and spinal cord
hippocampus - -formation of long term
brainstem - -contains midbrain, medulla, memories
and pons
cingulate cortex - -directs ANS; plays role
medulla - -controls vital body functions ex: in decision making, emotion, anticipation of
heart rate, breathing reward, empathy
pons - -control the management of sleep, amygdala - -fear and aggression
arousal, facial expression
nucleus accumbens - -reward and pleasure
cerebellum - -maintaining balance and
motor coordination
corpus callosum - -connects hemispheres
cerebellum - -contains more neurons than
the rest of the brain cerebral cortex - -thin layer of gray matter
covering cerebral hemispheres
midbrain - -controls sensory reflexes,
movement, pain frontal lobe - -primary motor cortex and
areas responsible for most complex cognitive
processes
reticular formation - -controls mood,
arousal, sleep; major source of serotonin and
norepinephrine Broca's area - -speech production in left
hemisphere
thalamus - -controls sensation, memory,
states of consciousness; receives sensory input prefrontal cortex - -planning behavior,
from most systems attention, and judgement
basal ganglia - -voluntary movement; orbitofrontal cortex - -emotion, impulse
degeneration in Parkinson's, also involved in control
OCD and ADHD
occipital lobe - -primary visual cortex
hypothalamus - -involved w/ motivation
and homeostasis; regulates temperature, hunger
, HOSA behavioral health knowledge
temporal lobe - -primary auditory cortex pineal gland - -releases melatonin;
maintenance of sleep-wake cycles
parietal lobe - -primary somatosensory
cortex (involved in neglect syndrome) pituitary gland - -master gland; stimulates
activity of other glands
lateralization - -localization of function in
one of the hemispheres (Ex: language lateralized main parts of the neuron - -soma (cell
in the left hemisphere) body), axons (transmit info), dendrites (receive
info)
Peripheral Nervous System - -nerves and
ganglia outside the CNS; contains somatic and glial cells - -provide structural matrix, clean
autonomic nervous systems up debris, form blood-brain barrier
somatic nervous system - -transmits myelin - -insulating material covering
commands for voluntary movement axons; increase conduction
autonomic nervous system - -controls glial cells - -cells that form scar tissue in
glands and organs; contains sympathetic and the brain and spinal cord
parasympathetic nervous system
young adulthood - -The prefrontal cortex in
sympathetic nervous system - -fight or myelinated in
flight; expenditure of energy
action potential - -electrical signal arising in
parasympathetic nervous system - -rest a neurons axon
and digest; storage of energy
resting potential - -electrical charge across
enteric nervous system - -nerve cells membrane when neuron is not firing
embedded in lining of gastrointestinal system;
communicates with endocrine system; source of
95% of boys serotonin action - -The _________ potential is
initiated when the membrane is depolarized to
threshold
endocrine system - -responsible for
release of hormones into bloodstream;
responses to input from hypothalamus synapse - -point of communication
between neurons
