The main functions of the somatosensory system are the perception of external stimuli, the perception of internal stimuli, and the regulation of body position and balance (proprioception). [2] Mechanosensory information includes that of light touch, vibration, pressure and tension in the skin.
The sense of balance or equilibrioception is the perception of balance and spatial orientation. [1] It helps prevent humans and nonhuman animals from falling over when standing or moving. Equilibrioception is the result of a number of sensory systems working together; the eyes ( visual system ), the inner ears ( vestibular system ), and the ...
Maintaining balance requires coordination of input from multiple sensory systems including the vestibular, somatosensory, and visual systems. [3]Vestibular system: sense organs that regulate equilibrium (equilibrioception); directional information as it relates to head position (internal gravitational, linear, and angular acceleration)
The sensory nervous system is a part of the nervous system responsible for processing sensory information. 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 .
The vestibular system of the inner ear, vision and proprioception are the main three requirements for balance. [63] Moreover, there are specific devices designed for proprioception training, such as the exercise ball, which works on balancing the abdominal and back muscles.
In neuroanatomy, the primary somatosensory cortex is located in the postcentral gyrus of the brain's parietal lobe, and is part of the somatosensory system. It was initially defined from surface stimulation studies of Wilder Penfield , and parallel surface potential studies of Bard, Woolsey, and Marshall.
The somatosensory system is the nervous system pathway that is responsible for this essential survival ability used in adaptation. [1] There are various types of tactile discrimination. One of the most well known and most researched is two-point discrimination , the ability to differentiate between two different tactile stimuli which are ...
hearing and balance (the ear, which includes the auditory system and vestibular system) smell (the nose) taste (the tongue) 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 ...
