Document Summary
Report positions of skeletal muscles and joints. *these receptor"s abilities are reduced when an individual is drunk. Temperature (too extreme will be translated into pain) Information from skin and muscles of body wall, head, neck and limbs to cns. Lateral and anterior white matter in spinal columns. * spinothalamic and posterior column pathway - final destination in parietal lobe in postcentral gyrus. On the side of the spinal column (lateral) dorsal root ganglion or a cranial nerve ganglion. Delivers sensations from the receptors to the posterior gray horn, in a. 3 order neurons: first order neuron , second order neuron , third order neuron . Posterior gray horn to the thalamus. *sensations are always crossed at some point during the process. *all synapses meet in thalamus with the exception of cn i - olfactory nerve. Responsible for crude (cannot verify the intensity) touch and pressure. Proprioception (body balance/equilibrium) - parietal lobe and cerebellum work to maintain this.
