NURS 3130 Chapter Notes - Chapter 43-45: Brain Herniation, Intracranial Pressure, Glasgow Coma Scale
Document Summary
43 structure & function of the nervous system. Brain- describe basic functions or actions of: cerebrum. Provides information necessary for balance, posture, and coordinated muscle movement: brainstem. Serves as conduction pathway serves as site of desussation of tracts. The nervous system- basic components, functions and or actions of (what each one does in the body: central nervous system. (cid:272)e(cid:374)ter of hu(cid:373)a(cid:374)"s highest functions, governing thoughts, memory, reasoning, sensation, and voluntary movement. Hemispheres are connected by the corpus callosum (allows communication between hemispheres) Hemispheres divided into 4 lobes: frontal, parietal, temporal, occipital: peripheral nervous system- identify or name, functions in general, cranial nerves- what each one does, spinal nerves- cervical, thoracic, lumbar, sacral, autonomic nervous system. Ischemia (decreased blood flow) is a contributing factor either as the primary insult or as part of the secondary response. Ischemia results in immediate neurologic dysfunction due to inability of neurons to generate. Ischemia and hypoxia (decreased oxygen at the cellular level) usually occur together.
