Respiration contributes to the maintenance of physiological balance, including the regulation of body temperature.

TMJ Covered with

work together to facilitate biting, chewing, and other oral functions.

encompasses various components, including the teeth, jaws, temporomandibular joint (TMJ), muscles of mastication, salivary glands, taste buds, and other oral structures

transitory, gliding movement.

RESPIRATION 3 purposes

oral cavity is innervated by a complex neural system that includes

provide the framework for the teeth and play a crucial role in the process of mastication.

provide feedback regarding touch, temperature, and taste sensations

refers to the collective structures and functions involved in the process of chewing, swallowing, breathing and voice production.

Protection of the individual from undesirable food components

deglutition/swallowing

Composed of structures of the mouth and jaws considered collectively as they subserve the functions of mastication, deglutition, respiration and speech.

control the movements of the muscles involved in chewing, swallowing, and speech.

once the food is chewed, the next step is to swallow it.

6 Main Components of TMJ

produced by bringing air from the lungs to the larynx where the vocal folds may be held open to allow the air to pass through or may vibrate to make a sound (phonation).

muscular organ located in the oral cavity composed of muscles and covered with taste buds

for rotary or opening movement.

earliest means of food transport

4 FUNCTIONS OF THE STOMATOGNATHIC SYSTEM

Speech involves the precise movements of the mouth and vocal organs to produce clear and correct sounds.

elevates the mandible

Help further develop or allow jaw bone to grow

Large, flat teeth at the back of the mouth, responsible for crushing and grinding food.

2 cranial nerves contribute to the neural innervation of the oral cavity.

elevates and positions the mandible

chewing process.

muscles work together to coordinate the complex motions required for effective chewing and grinding of food.

Basal bones inferiorly

Basal bones superiorly

Speech enables the exchange of thoughts, ideas, and emotions between individuals.

Sublingual gland

External/Lateral Pterygoid

play a role in the body's immune response by trapping and filtering harmful bacteria and viruses that enter the body through the mouth and nose.

Respiration facilitates the exchange of oxygen and carbon dioxide between the body and the environment.

main nerve supply of the oral cavity.

4 parts of Periodontium

swallowing is a complex group of reactions to move food onwards in the digestive tract while preserving the airway

joint that connects the mandible to the skull.

elevates the mandible.

transport of material from mouth to esophagus:

Branch of dentistry concerned with the study of functions and activities of the different structures found in the oral cavity

main nerve involved in oral sensation and motor control

The process of respiration generates energy in the form of ATP (adenosine triphosphate) through cellular respiration.

Wharton’s duct

filter and help eliminate toxins, bacteria, and other harmful substances.

allows for the movement of the jaw, including opening and closing of the mouth, as well as side-to-side and forward-backward movements.

Broad teeth with cusps, involved in chewing and grinding.

STOMA

part of the lymphatic system and are located at the back of the throat.

Sharp-edged teeth at the front of the mouth used for cutting and biting.

deliver oxygen and nutrients to the oral tissues,

ventilation wherein there is the entrance of oxygen & release of carbon dioxide.

2 Outer limiting structures

aqueous solution which moistens the oral cavity

Inner limiting structure

sucking/drinking

a continuous process closely associated with deglutition.

responsible for the movement of the jaw during chewing.

an expression of thought either written or spoken.

Stensen’s duct

separates upper and lower compartments.

Pointed teeth next to the incisors, used for tearing and gripping food.

GNATHIA

3 speech purposes

Speech requires coordination and control of the muscles involved in breathing, phonation, and articulation

physiologic activity formed when there is normal occlusion in a cyclic movement.

4 Muscles of Mastication

only movable bone in the skull and is connected to the skull through the temporomandibular joint (TMJ).

part of the body's defense mechanism against infections.

4 Functions of Muscles of Mastication

communication network that transmits information by electrical signal in and out of the CNS.
