Plicae in the ampulla refer to the small, fold-like structures found in the ampulla of the inner ear, specifically within the semicircular canals. These folds increase the surface area and are involved in the detection of angular motion and balance. They contain hair cells that respond to fluid movement, contributing to the body's sense of equilibrium. The plicae play a crucial role in converting mechanical stimuli into neural signals that the brain interprets for spatial orientation.

Which two ducts join together to form the ampulla of vater hepatopancreatic ampulla?
The common bile duct and the pancreatic duct join together to form the ampulla of Vater, also known as the hepatopancreatic ampulla. This structure empties into the duodenum and regulates the flow of bile and pancreatic juices into the small intestine for digestion.
What is the swollen area of semicircular canal?
The swollen area of the semicircular canal is known as the ampulla. Each of the three semicircular canals in the inner ear has an ampulla at its base, which contains sensory hair cells and supporting cells. These structures are responsible for detecting rotational movements of the head and help maintain balance and spatial orientation. The ampulla is crucial for the vestibular system's function, contributing to our sense of equilibrium.
What is the singular of plicae?

What is an ampulla of Vater?
An ampulla of Vater is a swelling which marks the union of the pancreatic duct and the common bile duct.

Yes.
What is an ampulla of Lorenzini?

What is plicae circularis?
Plicae circulares is a term used to describe permanent folds of mucous inside of the small intestine. These folds are within the membranes and are only in the lower part of the duodenum and jejunum.
