The tongue is very important in the formation of certain sounds and “phonemes” in speech. To understand what we mean, take the letter “T” as an example. If you say “T” to yourself aloud, you’ll feel your tongue brace against your upper teeth, and then move downward to produce the sound.
What is the main function of smooth muscle?
The primary function of smooth muscle is contraction. Smooth muscle consists of two types: single-unit and multi-unit. Single-unit smooth muscle consists of multiple cells connected through connexins that can become stimulated in a synchronous pattern from only one synaptic input.
What are examples of smooth muscles?
Smooth muscle cells are found in the walls of hollow organs, including the stomach, intestines, urinary bladder and uterus, and in the walls of passageways, such as the arteries and veins of the circulatory system, and the tracts of the respiratory, urinary, and reproductive systems.
What does a normal tongue look like?

How does the tongue work as a sense organ?
It is not only very movable, which allows us to speak, suck or swallow in a coordinated way. It is also a sensory organ responsible for tasting and the most sensitive place for our sense of touch. In addition, the tongue contains many cells of the body’s defense system, and even plays a major role in body language.
What disease affects the smooth muscle?
Multisystemic smooth muscle dysfunction syndrome is a disease in which the activity of smooth muscle throughout the body is impaired.
Does the tongue contain smooth muscle?
Skeletal muscle Striated muscle tissue can be actively and intentionally controlled – in contrast to smooth muscle tissue. Besides tongue, larynx and diaphragm, it comprises the whole skeletal muscle tissue which is responsible for movement and stabilization of your skeleton and extremities.
Is the tongue a striated muscle?
The tongue consists of striated muscle and occupies the floor of the mouth.

Open your mouth and look at your tongue. That may sound strange, but your tongue can tell a lot about your health.

Is the tongue an organ or muscle?
The tongue is a muscular organ in the mouth. The tongue is covered with moist, pink tissue called mucosa. Tiny bumps called papillae give the tongue its rough texture. Thousands of taste buds cover the surfaces of the papillae.
Why Genioglossus is called Safety muscle of tongue?
The genioglossus (GG, tongue) muscle plays an important role in maintaining upper airway patency. The GG is responsible for tongue protrusion and stiffens the tongue and prevents posterior tongue displacement and upper airway closure. The GG is a phasic respiratory muscle.
