Final answer:
The correct answer is C) Bursa, which is a sac filled with lubricating fluid that reduces friction between soft tissues like muscles or tendons and bones at or near joints.
Step-by-step explanation:
The term for a sac of fluid that reduces friction between a soft tissue and a bone is C) Bursa. Bursae are fluid-filled sacs that serve to prevent friction where soft tissues such as skin, ligaments, muscles, or muscle tendons rub against bone, usually near a joint. They contain a lubricating fluid that allows for smooth movement and serves as a cushion. For instance, the prepatellar bursa is located over the kneecap and the subacromial bursa protects the tendon of the shoulder muscle as it passes under the acromion of the scapula.
A bursa is a sac of fluid that reduces friction between a soft tissue and a bone. It acts as a cushion and allows smooth movement between these structures. Bursae are located in regions where skin, ligaments, muscles, or muscle tendons can rub against each other, usually near a body joint.
