Study Notes
Elasticity and Collisions
- Elastic property: A material’s ability to return to its original shape and size after the deforming force is removed is known as elasticity.
- Inelastic collision: During an inelastic collision, kinetic energy is not conserved; some energy is transformed into other forms, like heat or sound.
- Hooke's Law: This law establishes that the extension of a spring is directly proportional to the force applied, up to the material's elastic limit.
Deformation Limits
- Elastic limit: If a body is distorted beyond its elastic limit, it undergoes permanent deformation and will not return to its original shape or size.
Forces and Oscillation
- Restorative force: A restoring force acts in the direction opposite to the displacement of an oscillating body, helping it return to its equilibrium position.
Gallbladder Surgical Procedures
- Cholecystectomy: This surgical procedure involves the complete removal of the gallbladder, often performed due to gallstones or other gallbladder diseases.
- Cholecystostomy: This procedure creates an opening into the gallbladder to allow for drainage, typically used in cases where a cholecystectomy is too risky.
Gallbladder Conditions
- Common bile duct calculi: This condition involves the formation of calculi (stones) in the common bile duct, leading to potential blockages and complications.
Extrahepatic Biliary Tract Obstruction
- Causes of EHBO: Extrahepatic biliary tract obstruction can result from various factors, including gallstones, tumors, or strictures, hindering the bile duct's proper function.
