Mouth Anatomy

The mouth, also known as the oral cavity, is the opening through which food enters the body. Reviewing the Mouth Anatomy can be handy when it comes to creating medical illustrations that involve structures within the oral cavity.

Parts of the Mouth Anatomy

  1. Lips: The lips are the fleshy, movable structures that surround the opening of the mouth. They are composed of skin, muscle, and connective tissue, and are important for speaking, eating, and protecting the teeth and gums.
  2. Tongue: The tongue is a muscular organ that is located in the mouth and is responsible for taste, speech, and the manipulation of food. It is covered in small bumps called papillae, which contain taste buds.
  3. Teeth: The teeth are hard, bony structures that are located in the jaw and are used for biting and chewing food. They are divided into four types: incisors, canines, premolars, and molars.
  4. Salivary glands: The salivary glands are located in the mouth and are responsible for producing saliva, a fluid that helps to moisten food and start the process of digestion. There are three main pairs of salivary glands: the parotid glands, the submandibular glands, and the sublingual glands.
  5. Gums: The gums, also known as the gingiva, are the soft tissues that surround the teeth and hold them in place. They are composed of connective tissue and blood vessels, and are important for protecting the teeth and supporting the jaw.
  6. Palate: The palate is the roof of the mouth, which separates the oral cavity from the nasal cavity. It is divided into two parts: the hard palate, which is made of bone, and the soft palate, which is made of muscle and connective tissue.
  7. Uvula: The uvula is a small, finger-like structure that hangs from the soft palate. It plays a role in speech and swallowing, and it helps to keep food and liquids from entering the nasal cavity.

How is your tongue attached to your mouth?

The tongue is attached to the floor of the mouth by several different structures. The most prominent of these is the frenulum, which is a thin band of tissue that connects the bottom of the tongue to the floor of the mouth. This band of tissue is called lingual frenulum.

The tongue is also attached to the floor of the mouth by several small muscle groups, including the genioglossus, hyoglossus, and styloglossus muscles. These muscles work together to control the movement of the tongue, allowing it to move up, down, and side to side.

The tongue is also supported by several ligaments, including the stylohyoid ligament, which connects the tongue to the hyoid bone in the neck, and the median and lateral glossoepiglottic ligaments, which attach the tongue to the epiglottis.

In addition to these structures, the tongue is also attached to the skull by the styloid process, which is a small bony protrusion located on the skull just behind the jaw.

Is the mouth considered an external organ?

The mouth is considered to be an internal organ, not an external organ. The mouth, also known as oral cavity, is located inside the body, and it is a part of the digestive system.


In summary, knowing about the mouth anatomy is very important and useful when it comes to producing accurate medical illustrations. The mouth is an important structure, via which food enters the body and is composed of several different structures such as Lips, Tongue, Teeth, Salivary glands, Gums, Palate, and Uvula. These structures work together to enable us to eat, speak and taste, as well as provide protection and support to the jaw.
