A&P Flashcards
(51 cards)
the central nervous system consists of
the brain and spinal cord
the peripheral nervous system consists of
the peripheral nerves
The cerebrum consists of (3 parts)
cortex
basal ganglia
limbic system
function of the cortex
functions in higher brain processes such as thought and action. controls all voluntary activity (with the help of the cerebellum)
right and left cortex function
divided into two hemispheres
right side associated with creativity and the left side with logic
what connects the two hemispheres
the corpus callosum a bundle of axons
the 4 lobe divisions of the cerebral cortex
frontal
parietal
temporal
occipital
purpose of frontal lobe
reasoning, problem solving, parts of speech, movement and emotion
prefrontal cortex purpose
planning and consequences of action
purpose of parietal lobe
perception/recognition of stimuli, orientation and movement (body sensation and somatosensory)
purpose of temporal lobe
memory, perception/recognition of auditory stimuli and speech
purpose of occipital lobe
visual processing
basal ganglia function
voluntary motor movement, coordination, cognition and emotion
limbic system includes (4 parts)
thalamus, hypothalamus, amygdala and hippocampus
amygdala location and purpose
located: in the temporal lobe
involved in memory, emotion and fear
hippocampus purpose
learning and memory
converts short-term memory into long term memory
diencephalon two parts
thalamus and hypothalamus
location and function of the thalamus
located deep in the forebrain
processes nearly all sensory & motor information
relays info to and from overlying cortex
last relay site to all sensory input (except olfaction) before the information about sensory input reaches the cortex
location and function of the hypothalamus
located below and ventral to the thalamus
controls homeostasis
brainstem purpose and divisions (3)
controls vital life functions (breathing, heart rate, blood pressure)
midbrain
pons
medulla oblongata
midbrain purpose
controls eye movement, relays visual and auditory information
pons purpose
regulates breathing, serves as a relay station between the cerebral hemisphere and the medulla. involved in motor control and sensory input
medulla oblongata purpose
extension of the spinal cord (between pons and spinal cord)
regulated vital body functions (along with the pons) such as heart rate, breathing, autonomic centers, swallowing and coughing
cerebellum location
posterior to the medulla
