oral physio sas2

What is the definition of physiology?

• The study of the structure of the human body.
• The study of the functions and activities of living matter.
• The study of the chemical composition of living organisms.
• The study of the interaction between organisms and their environment.

Oral physiology specifically focuses on:

• The functions of the digestive system as a whole.
• The functions of the oral cavity and associated structures.
• The mechanics of speech and language production.
• The development of teeth and supporting structures.

The term "stomatognathic" comes from the Greek words for:

• Teeth and gums.
• Saliva and swallowing.
• Mouth and jaw.
• Chewing and digestion.

Which of the following is NOT a component of the stomatognathic system?

• Teeth and their supporting structures.
• The esophagus.
• The temporomandibular (jaw) joints.
• Muscles, blood vessels, and nerves in the region.

What is the primary function of the jaws in the stomatognathic system?

• Producing saliva for digestion.
• Providing attachment points for muscles and supporting teeth.
• Controlling the movement of the tongue.
• Regulating airflow during breathing.

Besides mastication, what other function do teeth serve?

• Phonation (speech production).
• Temperature regulation.
• Sensory perception of taste.
• Facial expression.

The tongue is characterized as a:

• Rigid and bony structure.
• Highly muscular and adaptable organ.
• Passive organ with limited movement.
• Primary site of taste bud concentration.

What is the influence of muscles on the teeth and supporting structures?

• Muscles only affect teeth during active chewing.
• Muscles exert constant force, both active and at rest.
• Muscles play a minimal role in dental arch integrity.
• Muscle function primarily affects facial expressions.

The arrangement of teeth within the dental arches is a result of:

• Genetic factors alone.
• Dietary habits and food choices.
• Morphogenetic patterns and muscle forces.
• Random variations during development.

What is the definition of mastication?

• The movement of food through the digestive tract.
• The absorption of nutrients from food.
• The process of crushing and grinding food with teeth.
• The swallowing of food.
