What is the central nervous system composed of?
brain and spinal cord
what is the peripheral nervous system composed of
peripheral nerves connecting the CNS to receptors, muscles and glands, including cranial nerves
what is the peripheral nervous system comprised of
“SA”
somatic nervous system and autonomic nervous system
what does the somatic nervous system do
conveys info from CNS to skeletal muscles
*voluntary movement
what does the autonomic nervous system do
regulates body functions to maintain homeostasis
conveys info from CNS to to smooth muscle, cardiac muscle and glands
*involuntary movement
what is the autonomic system composed of
parasympathetic and sympathetic nervous system
parasympathetic nervous system duties
*inhibits or decreases activity of organs
maintains or restores energy
sympathetic nervous system duties
*stimulates or increases activity of organs
prepares body for stress (fight or flight)
what is grey matter composed of
nerve cell bodies and dendrites
working area of the brain that contains the synapses and is the area of neural connection
grey matter
what is the brain subdivided into
the cerebrum and brainstem
largest part of the brain
cerebrum
the cerebrum is divided into what
right and left hemisphere
what are the hemispheres connect with
the corpus callosum
large area of white matter
the sensorimotor information exchange between them
what are the four major lobes or the cerebrum
frontal
parietal
temporal
occipital
how does the frontal lobe function
motor
premotor
association- allows for memory trigger and leads to decision making
executive functions
Expressive speech (Broca’s Area)
personality development
what are the temporal lobe functions
language comprehension (Wernicke area)
primary auditory
memory
emotion
vision and sensory integration
what can problems in the frontal lobe cause
“PIE”
personality changes
emotional changes
intellectual changes
what can problems in the temporal lobe cause
visual or auditory hallucination
aphasia
amnesia
what are the occipital lobe functions
primary visual cortex
integration center - integrates vision with other sensory info
what can problems in the occipital lobe cause
visual field defects
blindness
visual hallucinations
parietal lobe functions
Primary sensory area
taste
reading and writing
what can problems in the parietal lobe cause
sensory-perceptual disturbances
agnosia (the inability to recognize familiar objects, people, or sounds despite having normal sensory function)
what does the cerebrum consist of
“Can Charlie Love Before Going”
Cerebral cortex
Limbic system
Basal Ganglia
