what type of receptors detect deep pressure and vibration?

Also, what is referred to simply as touch can be further subdivided into pressure, vibration, stretch, and hair-follicle position, on the basis of the type of mechanoreceptors that perceive these touch sensations. Both primary somatosensory cortex and secondary cortical areas are responsible for processing the complex picture of stimuli transmitted from the interplay of mechanoreceptors. The average intensity of light emerging from a polarizing sheet is 0.764W/m20.764 \mathrm{W} / \mathrm{m}^{2}0.764W/m2, and the average intensity of the horizontally polarized light incident on the sheet is 0.883W/m20.883 \mathrm{W} / \mathrm{m}^{2}0.883W/m2. d.

Which receptor detects pressure changes? The cells that interpret information about the environment can be either (1) a neuron that has a free nerve ending(dendrites) embedded in tissue that would receive a sensation; (2) a neuron that has anencapsulated ending in which the dendrites are encapsulated in connective tissue that enhances their sensitivity; or (3) a specialized receptor cell, which has distinct structural components that interpret a specific type of stimulus (Figure 13.1.1). Rhodopsin absorbs light rays Within the realm of physiology, senses can be classified as either general or special. What type of papillae is the largest and least numerous? Free nerve endings are sensitive to painful stimuli, to hot and cold, and to light touch. That makes them finely sensitive to edges and they come into use in tasks such as typing on a keyboard. *Vestibular Earwax is a combination of dead skin cells and __________.

(Note that the special senses are all primarily part of the somatic nervous system in that they are consciously perceived through cerebral processes, though some special senses contribute to autonomic function). CN 8 has two divisions, the __________ branch and the __________ branch. Nociceptors are sensory receptors that detect signals from damaged tissue or the threat of damage and indirectly also respond to chemicals released from the damaged tissue.

These include receptors for taste and smell as well as visceral receptors that are sensitive to changes in the plasma level of O 2, pH, and osmolality. Somatosensation is the group of sensory modalities that are associated with touch and limb position. Listing all the different sensory modalities, which can number as many as 17, involves separating the five major senses into more specific categories, or submodalities, of the larger sense.
