pcol unit3
purpose is to send motor commands from the brain to the peripheral body and relay sensory information from the sensory organs to the brain
spinal cord
responsible for receiving, processing, and responding to sensory information
central nervous system
outermost layer that surrounds the brain
cerebral cortex
for voluntary motor function, problem-solving, attention, memory, and language
frontal lobe
for processing sensory information and contains the somatosensory cortex
parietal lobe
Visual processing center, contains the visual cortex
occipital lobe
Receives information from the retina
occipital lobe
Processes auditory stimuli through the auditory cortex
temporal lobe
Responsible for muscle movements and coordination
Basal Nuclei
Regulation of conciousness and sleep
Thalamus
Maintenance of homeostasis through coordination with the endocrine system
Hypothalamus
found in brainstem; comprises tracts responsible for relaying impulses from the motor cortex to the cerebellum, medulla, and thalamus.
pons
monitors the body's respiratory system, regulate blood pressure, pulse, cardiac contractions, vomiting, swallowing, coughing, sneezing
medulla obongata
responsible for smooth, coordinated voluntary movements
cerebellum
extends from the foramen magnum of the skull to the first or second lumbar vertebrae
spinal cord
Consists of the nerves that branch out from the brain and spinal cord.
peripheral nervous system
consists of nerves that go to the skin and muscles and is involved in volunatry activities
somatic nervous system
consists of nerves that connect the CNS to the visceral organs such as the heart, stomach, and intestines
Autonomic nervous system
