Document Summary

Central nervous system (cns) brain, spinal cord. Peripheral nervous system (pns) composed of 2 subdivisions: somatic nervous system (sns) sensorimotor connections via spinal and cranial nerves, autonomic nervous system (ans) balances the internal organs through the parasympathetic and sympathetic nerves. Parasympathetic rest or digest heart rate slows, respiration decreases, blood pressure and muscle tone relax para = relaxed. Sympathetic body is in mode to react to threats fight or flight heart rate quickens, increased respiration and blood pressure, digestive tract slows down. Skull and vertebrae: brain enclosed in the neurocranium (posterior portion of the skull, vertebral column which consists of 33 articulating bones. Cerebrospinal fluid (csf): cushions the brain and the spinal cord. Neurocranium = parietal, frontal, temporal and occipital bones (brain underneath. Lobes correspond to the skull bones they are under (temporal bone and temporal lobe is underneath) 2 bones of each on either side of the skull. Posterior cranial fossa bottom/back end of the brain (skull)
