The tongue anatomy. The tongue is a muscular organ in the mouth of most vertebrates that manipulates food for mastication and is used in the act of swallowing. Anatomy of the tongue. The tongue and its muscles are laterally symmetrical.

The tongue is made up of two types of muscles. It lies partly in the mouth cavity and partly in the oropharynx. The tongues upper surface is covered by taste buds housed in numerous lingual papillae.

The tongue is unique in that it is the only muscle that isnt connected to bone at both ends. It has a rough dorsal superior surface that abuts the palate and is populated with taste buds and lingual papillae and a smooth ventral inferior surface that is attached to the floor of the oral cavity by the lingual frenulum. It is connected to the mouth by the frenulum a thinly layered stretch of tissue that prevents the tongue from being swallowed.

Tongue anatomy parts pictures diagram of human tongue. The tongue has a lot of movement due to eight pairs of muscles. Different speech organs include tongue teeth lips palate and uvula etc.

The tongue is covered with moist pink tissue called mucosa. Four pairs are intrinsic and four pairs are extrinsic. The tip of the tongue the body and the back significantly contribute to the production of vowel and other sounds.

Your mouth cavity is home to various organs of speech. Extrinsic muscles originate from elsewhere in the body and attach to the tongue. There are four paired intrinsic muscles of the tongue and they are named by the direction in which they travel.

It is connected on one end to the hyoid bone which is also unique as it is the only bone not connected to any other bone in the body. The human tongue is a muscular organ that is covered by a thin mucous membrane. Here tongue is of incredible importance.

They connect with surrounding bones and help the organ move up and down from side to side and in and out. A median septum divides the organ into two halves. The tongue is a muscular organ in the mouth.

It has importance in the digestive system and is the primary organ of taste in the gustatory system. Taste buds are collections of nerve like cells that connect to nerves running into the brain. Thousands of taste buds cover the surfaces of the papillae.

The tongue also serves as a natural means of cleaning the teeth. The superior longitudinal inferior longitudinal transverse and vertical muscles of the tongue. These muscles affect the shape and size of the tongue for example in tongue rolling and have a role in facilitating speech eating and swallowing.

Theyre divided by the lingual septum. It is highly mobile and can be shifted into a number of different positions and also assume various shapes. The anatomy of the tongue consists of a series of eight muscles with a covering of mucous membrane and small bumps known as papillae.

Tiny bumps called papillae give the tongue its rough texture. The tongues primary physiologic function is gustatory sensation tasting and aiding in mastication chewing. Tongue as an organ of speech.

It is sensitive and kept moist by saliva and is richly supplied with nerves and blood vessels.
