NURS 363 Lecture Notes - Lecture 10: Peripheral Neuropathy, Physical Examination, Neurological Examination
Document Summary
Neuro: structure and function of the neurologic system. Central nervous system (cns: cerebral cortex, frontal- behavior, emotions, parietal, occipital- vision, temporal- changes with alzheimer"s, wenicke"s area f. Brocas area: basal ganglia, thalmus- relay station for neurons, hypothalamus- vital sign function; endocrine system, cerebellum motor coordination; balance, brainstem control vital function, medulla, pons, midbrain e. Spinal cord- houses and protects nerve fibers: pathways of the cns a. Sensory (afferent)- sensation follows a dermatome pathway: spinothalamic tract, posterior (dorsal) column, motor (efferent, corticospinal/pyramidal tract. Extrapyramidal tract i: cerebellar system, crossed representation, right brain: control left side of body ii. Herniation: supratentorial, mass above or within the cerebral hemisphere that creates downward pressure. Peripheral nervous system (pns: cranial nerves i xii . Pg 627: spinal nerves dermatome, autonomic nervous system somatic (skeletal/voluntary muscle) and autonomic (smooth/involuntary muscle, cardiac muscle, glands. Divided into sympathetic and parasympathetic: sympathetic controls vital body functions such as respiratory rate, heart rate.
