Study with Quizlet and memorize flashcards containing terms like A cell specialized to respond to a particular type of stimulus is a A) saccule. We avoid using tertiary references. The (Ventral/Dorsal) roots innervate the skeletal muscles. Many nociceptors of the joint respond to innocuous movements but are increasingly activated when movements exceed the physiological working range, whereas other nociceptors are active exclusively during noxious movements. skin), deep somatic (e.g. A variety of receptor typesembedded in the skin, mucous membranes, muscles, joints, internal organs, and cardiovascular systemplay a role. a) Proprioceptive information from the knee joint b) Pain sensation from the fingertip c) Visual stimulation from the retina of the eye d) Vasoconstriction impulse sent to the b, Sense of touch; understanding what we are touching: a) Parietal lobe b) Primary motor cortex c) Fusiform area d) Prefrontal cortex e) Temporal lobe f) Frontal lobe g) Primary somatosensory cortex h) Occipital lobe, Which of the following would be classified as special sensory information? Not every nociceptor responds to each type of noxious stimuli.

What is the only special sense in which signals can reach the cerebral cortex without passing first through the thalamus? Nociceptors often referred to as your "pain receptors," are free nerve endings located all over the body, including the skin, muscles, joints, bones, and internal organs. The blind spot is the location in the eye where the axons of the ganglion cells pass through the retina. A.

The AGSLog table stores the grading D) vibration. First, physical changes (joint effusion and tissue edema) alter the resting and movement-induced forces exerted on the joint tissues, and second, inammatory mediators released within the damaged tissue sensitize articular nociceptive afferents by binding to receptors on the nerve endings. Explore the protective structures, anterior eye, and the use of tears & secretions in the eyes. Heres more about somatic versus visceral pain, and when to see your doctor. D) humans lack receptors for every possible stimulus. However, if your pain continues, you need to talk with your doctor. Visceral pain is pain that results from the activation of nociceptors of the thoracic, pelvic, or abdominal viscera (organs). Nerve impulses responsible for the sensation of taste are carried in all of the following cranial nerves except: a. VII. However, in the same study, the nerve ber density in the peritendineum of the rat calcaneal tendon was found to be several times higher than that in the GS muscle. During the second phase of pain, the C fibers are activated, causing a person to experience an intense, burning pain that persists even after the stimulus has stopped.

The following are examples of renewable energy resources EXCEPT A. tidal forcesnuclear energyB. $$. D) The lens of the eye stiffens with age, making it difficult to focus on nearby objects. Polymodal nociceptors can be triggered by intense mechanical, chemical or thermal (hot and cold) stimuli and are found at the ends of very small diameter unmyelinated axons that conduct information slower than specifically thermal nociceptors and mechanical nociceptors. Somatic pain happens when any of the pain receptors in your tissues, such as muscles, bone, or skin, are activated. how having the pain makes you feel. Following joint damage, two factors combine to alter the mechanical sensitivity of articular nociceptors. Cell Tissue Res. The nociceptors can also detect chemical and thermal damage.
