Study Notes
Dental Anatomy
- The crown of a tooth is covered by enamel.
- The root of a tooth is covered by cementum.
Thermoregulation
- Newborn infants lose heat the fastest in cold environments compared to adults and children.
Metabolism
- Glycolysis can proceed without the presence of acetyl-CoA.
- During lipolysis, triglycerides are broken down into glycerol and fatty acids.
- Lipogenesis typically starts with acetyl-CoA.
Digestive Tract Functions
- The fusion of the hepatic duct and cystic duct forms the common bile duct.
- A structure preventing premature entry of food into the pharynx is the uvula.
- The middle segment of the small intestine is the jejunum.
- Functions of teeth include crushing, clipping, cutting, and tearing.
Salivary Glands
- Blockage of parotid gland ducts inhibits carbohydrate digestion in the mouth.
Nutrient Digestion
- Pepsin is the enzyme responsible for protein digestion.
- Carbohydrate digestion begins in the mouth.
- Absorption of monosaccharides does not occur in the oral cavity.
Digestive System Functions
- The digestive system's functions include ingestion, mechanical processing, compaction, and absorption; filtration is not a function.
Muscle Function and Essentials
- Calcium is essential for muscle contraction, nerve function, and blood clotting.
Absorptive State
- During the absorptive state, the liver forms glycogen from excess glucose.
Deglutition Process
- During deglutition, all listed processes occur: the soft palate elevates, the larynx lifts, and the lower esophageal sphincter opens.
Gingiva
- The ridge of oral mucosa surrounding a tooth's base is called the gingiva.
Digestive Layer Structure
- The submucosa layer of the digestive tract consists of dense irregular connective tissue that supports the muscularis mucosae.
