What are the names of the mouth parts?
The mouth consists of two regions: the vestibule and the oral cavity proper. The vestibule is the area between the teeth, lips and cheeks. The oral cavity is bounded at the sides and in front by the alveolar process (containing the teeth) and at the back by the isthmus of the fauces.Its roof is formed by the hard palate at the front, and the soft palate at the back.
What is the tooth in the mouth?
Teeth are the more characteristic part of the mouth's anatomy. They are white colored calcified organs embedded partially in sockets of the lower and upper jaws. The crown is the visible part of the tooth above the gums, while the root of the tooth keeps it in place with the help of the periodontal ligament that anchors it to the alveolar bone.
What are the soft parts of the mouth?
The lips are the soft parts of tissue at the front edge of the cheeks that form the anterior boundary of the mouth. They are covered externally by skin and internally by the same mucous membrane (mucosa) that lines the entire oral cavity. The lips help keep saliva and food inside the mouth and move it over the teeth for chewing. They are also important in the formation of speech and in several behavioral expressions such as kissing or laughing.
What are the two main salivary glands?
The salivary glands provide our mouth with saliva. There are three pairs of major salivary glands (one on each side of the face): 1 The parotids are the largest salivary glands located near the masseter muscle below the ear. They secrete saliva on the inside of the cheek next to the upper molar teeth. 2 The submandibular salivary glands are located deep into the mandible (lower jaw bone). They release saliva underneath the front of the tongue, behind the front teeth. 3 The sublingual salivary glands, the smallest ones, are located under the tongue secreting saliva from many small openings under the tongue. 4 Hundreds of smaller salivary glands can be found in the oral cavity at the cheeks, lips, tongue, hard and soft palates, and the floor of the mouth.
