In the abdomen, general visceral afferent fibers usually accompany sympathetic efferent fibers. This means that a signal traveling in an afferent fiber will begin at sensory receptors in the afferent fiber's target organ, travel up to the ganglion where the sympathetic efferent fiber synapses, continue back along a splanchnic nerve from the ganglion into the sympathetic trunk, move into a ...
The concept of interoception was introduced in 1906 by the Nobel Laureate Sir Charles S. Sherrington.He did not use the noun interoception, but did describe as interoceptive [12] those receptors that are within the viscera—what are today called "visceroceptive"—and thus excluded all other receptors and information from the body, which he grouped as either exteroceptive or proprioceptive.
A sensory system consists of sensory neurons (including the sensory receptor cells), neural pathways, and parts of the brain involved in sensory perception and interoception. Commonly recognized sensory systems are those for vision , hearing , touch , taste , smell , balance and visceral sensation.
Awareness is a relative concept.It may refer to an internal state, such as a visceral feeling, or on external events by way of sensory perception. [2] It is analogous to sensing something, a process distinguished from observing and perceiving (which involves a basic process of acquainting with the items we perceive). [4]
Visceral pain is pain that results from the activation of nociceptors of the thoracic, pelvic, or abdominal viscera (organs). Visceral structures are highly sensitive to distension (stretch), ischemia and inflammation , but relatively insensitive to other stimuli that normally evoke pain such as cutting or burning.
The distinction between special and general senses is used to classify nerve fibers running to and from the central nervous system – information from special senses is carried in special somatic afferents and special visceral afferents.
Sensory processing is the process that organizes and distinguishes sensation (sensory information) from one's own body and the environment, ...
The first is the "visceral" level which is about immediate initial reactions people unconsciously do and are greatly determined by sensory factors (look, feel, smell, and sound). Norman argued that attractive products work better because they can engage multiple senses to evoke emotional responses and bonds through use of visual factors of ...
