MeSH

The process in which specialized SENSORY RECEPTOR CELLS transduce peripheral stimuli (physical or chemical) into NERVE IMPULSES which are then transmitted to the various sensory centers in the CENTRAL NERVOUS SYSTEM.

Disorders of the special senses (i.e., VISION; HEARING; TASTE; and SMELL) or somatosensory system (i.e., afferent components of the PERIPHERAL NERVOUS SYSTEM).

Year introduced: 1993

A feeling of a lump in the throat that occurs between meals in the absence of other gastrointestinal and motility disorders (e.g., DYSPHAGIA; GASTROESOPHAGEAL REFLUX).

Year introduced: 2020

Disorders of sensory information received from superficial and deep regions of the body. The somatosensory system conveys neural impulses which pertain to proprioception, tactile sensation, thermal sensation, pressure sensation, and pain. PERIPHERAL NERVOUS SYSTEM DISEASES; SPINAL CORD DISEASES; and BRAIN DISEASES may be associated with impaired or abnormal somatic sensation.

Year introduced: 2000

Absent or reduced sensitivity to cutaneous stimulation.

Subjectively experienced sensations in the absence of an appropriate stimulus, but which are regarded by the individual as real. They may be of organic origin or associated with MENTAL DISORDERS.

An illusion of movement, either of the external world revolving around the individual or of the individual revolving in space. Vertigo may be associated with disorders of the inner ear (EAR, INNER); VESTIBULAR NERVE; BRAINSTEM; or CEREBRAL CORTEX. Lesions in the TEMPORAL LOBE and PARIETAL LOBE may be associated with FOCAL SEIZURES that may feature vertigo as an ictal manifestation. (From Adams et al., Principles of Neurology, 6th ed, pp300-1)

Perception of painful and nonpainful phantom sensations that occur following the complete or partial loss of a limb. The majority of individuals with an amputated extremity will experience the impression that the limb is still present, and in many cases, painful. (From Neurol Clin 1998 Nov;16(4):919-36; Brain 1998 Sep;121(Pt 9):1603-30)

Increased sensitivity to cutaneous stimulation due to a diminished threshold or an increased response to stimuli.

An increased sensation of pain or discomfort produced by minimally noxious stimuli due to damage to soft tissue containing NOCICEPTORS or injury to a peripheral nerve.

Year introduced: 1991(1975)

Sense of movement of a part of the body, such as movement of fingers, elbows, knees, limbs, or weights.
