Nociception (pain); Equilibrioception (balance); Mechanoreception (vibration, discriminatory touch and pressure); Proprioception (positioning and movement).
These sensory neurons have receptors that are classified according to the stimulus they respond to - there are mechanoreceptors for touch and proprioception, nociceptors for pain, and thermoreceptors for temperature.
Mechanoreceptors are one of the neural receptors in a somatosensory system. They are primarily involved in recognizing different mechanical stimuli. Example is the touch receptor in the skin. Insects are popular example of group of organisms with specialized structures for mechanoreception.
Somatosensation is also known as tactile sense, or more familiarly, as the sense of touch. Somatosensation occurs all over the exterior of the body and at some interior locations as well.
Somatosensation is a mixed sensory category and includes all sensation received from the skin and mucous membranes, as well from as the limbs and joints. Somatosensation is also known as tactile sense, or more familiarly, as the sense of touch.
Definition. A somatosensory sensation; the perception of sensory stimuli coming from the skin that involves senses of touch, temperature, body position, and pain.
Four major types of encapsulated mechanoreceptors are specialized to provide information to the central nervous system about touch, pressure, vibration, and cutaneous tension: Meissner's corpuscles, Pacinian corpuscles, Merkel's disks, and Ruffini's corpuscles (Figure 9.3 and Table 9.1).
mechanoreceptors. detect mechanical deformation e.g. touch or pressure in the skin; stretch receptors in muscles. * mechanoreceptor cells respond to a change in the external stimulus (pressure, temperature, etc) by producing voltage pulses across neurons (i.e. generator potentials) .
Mechanoreceptors are a type of somatosensory receptors which relay extracellular stimulus to intracellular signal transduction through mechanically gated ion channels. The external stimuli are usually in the form of touch, pressure, stretching, sound waves, and motion.
An individual sensory modality represents the sensation of a specific type of stimulus. For example, the general sense of touch, which is known as somatosensation, can be separated into light pressure, deep pressure, vibration, itch, pain, temperature, or hair movement.
The somatosensory systems process information about, and represent, several modalities of somatic sensation (i.e., pain, temperature, touch, proprioception).
Somatosensation (Touch) Somatosensation is considered a general sense, as opposed to the special senses discussed in this section. Somatosensation is the group of sensory modalities that are associated with touch, proprioception, and interoception.
