The tongue's intrinsic muscles allow some people to form their tongues into specific shapes. Rolling the tongue into a tube shape is often described as a dominant trait with simple Mendelian inheritance, and it is commonly referenced in introductory and genetic biology courses, although there is some disagreement.

Gorlin's sign. Gorlin’s sign is a medical term that indicates the ability in humans to touch the tip of the nose with the tongue. [1] Approximately ten percent of the general population can perform this act, but fifty percent of people with Ehlers–Danlos syndrome (an inherited connective tissue disorder) have the ability.
Mendelian traits behave according to the model of monogenic or simple gene inheritance in which one gene corresponds to one trait. Discrete traits (as opposed to continuously varying traits such as height) with simple Mendelian inheritance patterns are relatively rare in nature, and many of the clearest examples in humans cause disorders.
Human genetics is the study of inheritance as it occurs in human beings.Human genetics encompasses a variety of overlapping fields including: classical genetics, cytogenetics, molecular genetics, biochemical genetics, genomics, population genetics, developmental genetics, clinical genetics, and genetic counseling.
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.
Oral tongue cancer is a cancer that happens in the front two-thirds of the tongue, while oropharyngeal tongue cancer forms at the base of the tongue in the back portion of the mouth and can extend ...
“I broke down, crying, trying to put thoughts together and ask questions but physically couldn’t, all I heard was ‘option 1, surgery, 100% removal of your tongue,’” Chung wrote.
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 ...
