nervous system A+P CH.9 lecture 4
peripheral neuropathy
causes
trauma
anything causing mechanical injury to nerves
systemic diseases
infection and autoimmune causes
genetics
spinal cord injury
common causes
car accidents, violence, falls, work injuries, disease
phrenic nerve
motor nerve for diaphragm, if spinal cord is damaged below cervical plexus, phrenic nerve can receive signals from brain and send them to diaphragm and person can breathe
diagnosis
neurological exam testing sensory and motor function
imaging studies
MRI
X-ray
CT scan
myelography
lobes
inferior lobes
seperated by lateral sulci
temporal lobes
hearing and emotion
insula
deep in temporal lobe (fifth lobe), not visible on surface of cerebrum
contralateral
information coming into brain, left side of brain contolled by right side of cerebral cortex
cerebellum
posterior to cerebrum
vermis
divided into hemispheres by raised ridges
brain
acts as main processor and director of nervous system
brain has cerebrum
largest part of brain, divided by left and right hemispheres by longitudinal fissure and divided by cerebellum by transverse fissure
cranial nerve
leaves brain and goes to head, receives information and sends it back to brain, brain will send instructions for it to move (motor)
lobes named for skull bones that cover them
frontal lobe
most anterior lobes, separated from rest of brain by central sulci
responsible for motor activities, conscious thought and speech
parietal lobe
posterior to frontal lobe, body sense perception, taste and speech
occipital lobes
posterior to parietal lobes, responsible for vision
