facet : In clinical anatomy, a smooth joint-forming surface.

fascia: A layer of fibrous connective tissue that covers muscle.

fibrocartilage: This cartilage has a larger number of collagen fibers and less matrix. It’s found in the discs in joint spaces including the temporomandibular joint, knee joint, and joints between the bodies of the vertebrae.

fibrous joints: The bones of a fibrous joint are connected by fibrous tissue. They range from being immovable (like joints between the bones of the skull) to being slightly moveable (joints between the tibia and fibula in the legs).

foramina: Openings.

frontal planes: Imaginary vertical planes that clinical anatomy uses to define regions of the body. They pass through the body at right angles to the midsagittal plane, so they divide the body into front and back. Frontal (coronal) planes can divide the body at any point, so you need to use a reference point to know where exactly the plane passes.
