Perikaryal surface specializations of neurons in sensory ganglia.

摘要: Slender projections, similar to microvilli, are the main specialization of perikaryal surface sensory ganglion neurons. The extent these projections correlates closely with volume corresponding nerve cell body. It is likely that role neurons, which lack dendrites, maintain surface-to-volume ratio body above some critical level for adequate metabolic exchange. Satellite cells probably have ability promote, or provide a permissive environment for, outgrowth projections. not yet known whether effect satellite mediated by molecules associated their plasma membrane diffusible factors. Furthermore, receptor numerous chemical agonists located on surface, but it certain exclusively also present smooth between Further study and influence exert will improve our understanding interactions neurons neuroglial cells.
