What is the term used for the irritation and inflammation of the bursa?

The correct term for the irritation and inflammation of the bursa is bursitis. Bursae are small, fluid-filled sacs located throughout the body, particularly in areas where friction may occur between tissues, such as muscles, tendons, and bones. When these sacs become inflamed due to overuse, trauma, or other factors, it leads to bursitis. This condition is characterized by pain, swelling, and restricted movement in the affected area.

The other options refer to different conditions: hip bursitis specifically designates bursitis that occurs in the hip region, tendonitis refers to the inflammation of tendons, and arthritis is a general term for inflammation of the joints. Each of these terms describes different anatomical structures or conditions, which is why they do not apply to the irritation of the bursa specifically.
