In a case of gustatory allochiria, a substance placed on one side of the tongue was said to have been tasted on the opposite side. Also, touches on that side of the tongue were also referred to the opposite side. In this type of allochiria, it is difficult to see how one can in this case dissociate the reference of taste from that of touch. [12]
Two-point discrimination (2PD) is the ability to discern that two nearby objects touching the skin are truly two distinct points, not one.It is often tested with two sharp points during a neurological examination [1]: 632 [2]: 71 and is assumed to reflect how finely innervated an area of skin is.
Neck-tongue syndrome (NTS), which was first recorded in 1980, [1] is a rare disorder characterized by neck pain with or without tingling and numbness of the tongue on the same side as the neck pain. [2] Sharp lateral movement of the head triggers the pain, usually lasting from a few seconds to a few minutes. Headaches may occur with the onset ...
Area S2 processes light touch, pain, visceral sensation, and tactile attention. S1 processes the remaining info (crude touch, pain, temperature). [13] [14] [15] BA7 integrates visual and proprioceptive info to locate objects in space. [16] [17] The insular cortex (insula) plays a role in the sense of bodily-ownership, bodily self-awareness, and ...
The lingual nerve supplies general somatic afferent (i.e. general sensory) innervation to the mucous membrane of the anterior two-thirds of the tongue (i.e. body of tongue) (whereas the posterior one-third (i.e. root of tongue) is innervated via the glossopharyngeal nerve (CN IX) [citation needed]), the floor of the oral cavity, and the mandibular/inferior lingual gingiva.
Tongue strength may be tested by poking the tongue against the inside of their cheek, while an examiner feels or presses from the cheek. [6] The hypoglossal nerve carries lower motor neurons that synapse with upper motor neurons at the hypoglossal nucleus. Symptoms related to damage will depend on the position of damage in this pathway.

At times, the mucous membrane around the uvula may swell, causing the uvula to expand 3–5 times its normal size. This condition is known as uvulitis. This condition is known as uvulitis.
