Study Notes
Oral Cavity
- The oral cavity is divided into two parts by the upper and lower dental arches.
Pharynx
- The pharynx is located behind the oral and nasal cavities and above the esophagus.
- It is responsible for modifying the sound produced in the larynx.
- The pharynx has four main muscles and is also made up of several other muscles, primarily totaling around 20-25 muscles.
- In addition to being a part of the gastrointestinal tract, the pharynx also plays a role in the respiratory system.
Functions of the Oral Cavity
- The three major functions of the oral cavity are: receiving food and preparing it for digestion, aiding in the process of speech, and facilitating the sensation of taste.
Vestibule
- The vestibule is a part of the oral cavity located between the teeth and lips, and is responsible for directing food and drink towards the oral cavity.
Oropharyngeal Isthmus
- The oropharyngeal isthmus is located at the border between the oral cavity and the pharynx.
