Physical Suffering:

Terms Related to Physical Suffering

• Sensory Nerve Ending

  Specialized neurons or parts of neurons which transduce sensory information and relay it centrally. Included are receptors for stimuli outside the body (exteroceptors) as well ...

• Nerve Ending

  Specialized terminations of peripheral neurons. Nerve endings include NEUROEFFECTOR JUNCTION(s) by which neurons activate target organs and sensory receptors (see RECEPTORS, SENSORY) which transduce information ...

• Sensation

  Transduction of physical or chemical changes in the external or internal environment into nerve impulses by specialized receptors, transmission of these impulses by afferent neurons ...

• Nociceptor

  Peripheral receptors for pain. Nociceptors include receptors which are sensitive to painful mechanical stimuli, extreme heat or cold, and chemical stimuli. All nociceptors are free ...

• Neuroreceptor

  Specialized neurons or parts of neurons which transduce sensory information and relay it centrally. Included are receptors for stimuli outside the body (exteroceptors) as well ...

• Chemosympathectomy

  Sympathectomy using chemicals (e.g., 6-hydroxydopamine or guanethidine) which selectively and reversibly destroy adrenergic nerve endings while leaving cholinergic nerve endings intact.

• Pain Receptor

  Peripheral receptors for pain. Nociceptors include receptors which are sensitive to painful mechanical stimuli, extreme heat or cold, and chemical stimuli. All nociceptors are free ...
