Study Notes

Mouth Anatomy Overview

Upper Lip: The fleshy fold that forms the top part of the mouth.
Uvula: A small, fleshy extension at the back of the soft palate that helps with speech and prevents food from entering the nasal cavity.
Palatine Tonsil: Lymphoid tissue located on either side of the oropharynx, playing a role in immune function.

Pharynx and Cavity Structures

Oropharynx: The part of the pharynx located behind the oral cavity, involved in both respiratory and digestive functions.
Tongue: A muscular organ in the mouth important for manipulation of food, taste sensation, and speech.
Trachea: The airway leading from the larynx to the lungs, allowing air passage in respiratory processes.

Bone and Frenulum Functions

Hyoid Bone: A U-shaped bone in the neck that supports the tongue and aids in swallowing.
Lingual Frenulum: A thin fold of tissue that connects the underside of the tongue to the floor of the mouth, regulating tongue movement.
Oral Cavity: The space within the mouth that contains the tongue, teeth, and gums, crucial for digestion and speech.

Palate Types

Hard Palate: The bony front portion of the roof of the mouth, providing structure for the oral cavity.
Soft Palate: The flexible back portion of the roof of the mouth, aids in swallowing and separating the nasal cavity during speech.

Additional Pharyngeal Structures

Nasopharynx: The upper part of the pharynx that connects with the nasal cavity, important for respiratory function.
Epiglottis: A flap of cartilage located at the base of the tongue that prevents food from entering the trachea during swallowing.
Laryngopharynx: The lower part of the pharynx that connects to the esophagus, serving both respiratory and digestive purposes.

Esophagus and Dental Structures

Esophagus: The muscular tube that conveys food from the throat to the stomach.
Incisors: The front teeth primarily used for cutting food.
Cuspid (Canine): The pointed teeth located next to incisors, suitable for tearing food.
Premolars: The flat-topped teeth located behind canines, effective for crushing and grinding food.
Molars: The large, flat teeth at the back of the mouth, responsible for grinding food during chewing.
