Study Notes
Salivary Glands and Functions
- Parotid, submandibular, and sublingual glands are major salivary glands; the palatine gland is NOT a major gland.
- Myoepithelial cells assist in the expulsion of saliva along the duct.
- Saliva serves multiple functions including lubrication, food digestion initiation, and maintaining oral hygiene.
Digestive System Development
- The pancreas develops from the gut tube and maintains contact with digestive organs via ducts.
Salivary Gland Functionality
- The submandibular gland produces a watery secretion that accounts for about 60% of total saliva production.
Hormonal Regulation
- Glucagon stimulates glucose production through gluconeogenesis and glycogen breakdown in the pancreas.
Human Anatomy
- The liver is the largest and heaviest internal organ, weighing approximately 1.5 kg in an adult.
Liver Histology
- The portal triad consists of a bile duct, hepatic artery, and portal vein, and is essential for liver function and blood supply.
- Hepatic sinusoids are specialized capillaries in the liver that allow for the exchange of substances between blood and liver cells, increasing surface area for this function.
- Bile canaliculi are small channels between liver cells that transport bile to bile ducts, crucial for digestion.
- The gallbladder stores and concentrates bile; histologically, it has a muscular wall that facilitates bile release into the duodenum.
