If you broke the distal end of the two bones that articulate with the carpals, which bones did you break?

Anaerobic respiration can lead to a burning sensation caused by lactic acid. During intense physical activity or when oxygen availability is limited, cells may resort to anaerobic respiration, which involves the breakdown of glucose without the use of oxygen. As a byproduct of this process, pyruvate is converted into lactic acid. Accumulation of lactic acid in the muscles can lead to a burning sensation, muscle fatigue, and discomfort during strenuous exercise. Therefore, the presence of lactic acid is associated with the burning sensation experienced during anaerobic respiration.

The cell membrane, also known as the plasma membrane, regulates the transport of substances in and out of a cell. It acts as a selective barrier, controlling the passage of molecules and ions based on their size, charge, and lipid solubility. This regulation is essential for maintaining cellular homeostasis and ensuring that the cell's internal environment remains stable.

When antidiuretic hormone (ADH) is secreted, cells in the collecting tubules of the nephrons respond by increasing water reabsorption from the urinary filtrate. This action helps to concentrate urine and conserve water in the body, ultimately reducing urine output.

If you broke the distal end of the two bones that articulate with the carpals, you would have broken the ulna and radius. These two bones are part of the forearm and articulate with the carpals, which are the bones of the wrist. The distal ends of the ulna and radius form the wrist joint, allowing for movement of the hand. Therefore, a fracture at the distal end of the ulna and radius would affect the integrity and function of the wrist joint.
