Question

what is epidermis and Hyoid bone And synovial fluid​

Answer 1

Synovial fluid is a viscous solution found in the cavities of synovial joints. The principal role of synovial fluid is to reduce friction between the articular cartilages of synovial joints during movement.

Together with its attached muscles, the hyoid bone has two important functions: it holds up the tongue, which sits above it, and it holds up the larynx, which hangs below it. It also transmits the force of muscles that help to open the jaw.

Explanation:

The epidermis is the outermost of the three layers that make up the skin, the inner layers being the dermis and hypodermis. The epidermis layer provides a barrier to infection from environmental pathogens and regulates the amount of water released from the body into the atmosphere through transepidermal water loss.
