Visceral sensory (afferent) neurons:Group of answer choicesare responsible for providing information to the CNS about stretch, distension and/or noxious stimuli associated with the visceraare responsible for referred pain because they have branches that also innervate somatic tissuesinnervate the heart where they increase activity in the SA noderefer pain to visceratravel mostly with components of the parasympathetic nervous system

Which of the following is TRUE about the high-threshold, nociceptive (pain-mediating) extrinsic sensory neurons that innervate the viscera?  they are part of the parasympathetic nervous system   they are not part of the autonomic nervous system at all   they are part of the sympathetic nervous system   they are part of both the sympathetic and parasympathetic nervous systems   they are part of the enteric nervous system

Fill in the Blank QuestionFill in the blank question.Sensory signals from the skin (i.e. touch, pressure, pain) are ultimately directed to the lobe of the cerebrum to an area called the somatosensory cortex.

Nerve receptor cells for the skin senses areMultiple Choicelocated at a uniform depth throughout the skin.not associated with chronic pain.unevenly distributed throughout the skin.not related to the sense of pressure.

Describe the structures that act as pain receptors.Multiple ChoiceEncapsulated nerve endingsSpecialized receptors within complex structuresFree nerve endings

A 32-year-old woman experienced the sudden onset of a severecramping pain in the abdominal region. She also becamenauseated. List some of the common features of visceral pain.A. It results from activation of nociceptors in the viscera thatare innervated by the same fibers as innervate skin, inducesrapid shard pain, causes spasms of the visceral muscle, andshows relatively rapid adaptation.B. It is mediated by Aδ and C fibers in the ventral rootsof spinal nerves, radiates to a nearby or distant somaticstructure, is accompanied by sweating, and is relayed to thecortex by the spinothalamic tract.C. It is poorly localized, is accompanied by sweating, radiates toa somatic structure that may be some distance away, and isrelayed to the somatosensory cortex via the spinothalamic tract.D. It requires simultaneous activation of nociceptors withinand outside of the viscera, causes spasms of the visceral andskeletal muscle, and is relayed to the cortex by the dorsalcolumn pathway.E. It is well localized, is accompanied by sweating, radiates toa somatic structure that may be some distance away, andcauses spasms of visceral muscle.
