Term
receptors
Definition
receives input
Term
somatic sensory receptor
Definition
senses things from outside environment
Term
visceral sensory receptor
Definition
senses things from internal conditions/organs
Term
afferent division
Definition
sends sensory info to cns
Term
sensory neurons
Definition
sends info from receptors to afferent division
Term
cns, central nervous system
Definition
analyses sensory info and coordinator of output
Term
cns includes...
Definition
brain + spinal cord
Term
pns, peripheral nervous system
Definition
all nerves that branch out from cns, extend to other parts of body
Term
interneurons
Definition
sends info from aff div to cns to eff div
Term
efferent division
Definition
motor commands from cns
Term
somatic nervous sytem
Definition
voluntary actions
Term
autonomic nervous sytem
Definition
involuntary actions
Term
parasympathetic division
Definition
rest and digest, sit and sh
Term
sympathetic division
Definition
fight or flight
Term
skeletal muscle
Definition
voluntary muscle
Term
smooth/cardiac muscle, glands, adipose tissue
Definition
involuntary muscles
Term
effectors
Definition
muscles and glands as an effect in response to directions from the nervous system, motor output or motor function
Term
motor neurons
Definition
sends info from eff div to the rest
Term
cerebrum
Definition
as a whole, voluntary actions: conscious thoughts, intellectual functions, memory and learning, and information retrieval
Term
diencephalon
Definition
relay and process centres for sensory information
Term
cerebellum
Definition
fine-tunes motor activities based on sensory information and prior knowledge, regulates fear and pleasure responses
Term
midbrain
Definition
process visual/auditory information and generates involuntary motor responses
Term
pons
Definition
"bridge" connecting cerebellum to brain stem, voluntary motor control
Term
medulla oblongata
Definition
autonomic functions
Term
lobes
Definition
different parts of the brain that have separate functions
Term
4 lobes
Definition
frontal, parietal, occipital, temporal
Term
frontal lobe
Definition

anterior portion

memory, reasoning, speech (mrs)

Term
parietal lobe
Definition

between the central sulcus and parieto-occipital sulcus

integrate sensory info, touch

Term
occipital lobe
Definition

posterior part of the brain

sense of sigh and visual info

Term
temporal lobe
Definition

inferior portion of brain

sense of smell, taste, sound

hippocampus

Term
hippocampus
Definition
memory from experienced events, navigation, and processing conflict
Term
function of sulci and gyri

pineal gland
Definition
regulates day-night cycles, melatonin
Term
amygdala
Definition
processing of memory, emotions (namely fight/flight), and making decisions
Term
longitudinal fissure
Definition
"buttcrack for the brain", mid-saggital division between the lateral hemisphere
Term
corpus callosum
Definition
links the two hemispheres together
