Articulations

two layers that surround and enclose a synovial joint. The outer layer is spongy fibrous connective tissue, and the inner layer is the synovial membrane.

hyaline cartilage that protects the surface of bones found in synovial joints

small, oval fibrocartilage structure that divides the synovial joint cavity

synovial fluid–filled thin connective tissue sac often associated with synovial joints that serves to reduce friction between adjacent structures, such as ligaments and bones

joint where bones are separated by cartilage

distance between the point of muscular force on a bone and the fulcrum

strong, flexible cartilage containing thick, fibrous collagen

joints that occur where bones are attached by the collagen fibers of a fibrous connective tissue

point a bar pivots around in a lever system. Physiologically, this occurs in the synovial joints of the body.

narrow fibrous peg-and-socket joint found between the roots of teeth and the sockets in the jawbones

firm, translucent cartilage found in joints

location where two bones meet

fluid-filled enclosed cavity found at synovial joints

simple machine that operates by pivoting around a fixed point, or fulcrum

tough, fibrous band of connective tissue that holds bones together at joints

when the effort arm is longer than the load arm, allowing levers to use little force to move a large load

large, C-shaped fibrocartilage structure that partly divides a synovial joint cavity

distance between the resistance (or load) a muscle is working against and the fulcrum (or joint) in a lever system

type of fibrous joint connecting bones in the skull

slightly movable and permanent cartilaginous joint where the bones are joined by fibrocartilage

cartilaginous joint where bones are joined together by hyaline cartilage

fibrous joint between bones that are held together by a ligament

bony junction that forms when connective tissue between two bones is replaced with bone tissue, fusing the two bones into one

lubricating fluid that fills synovial joint cavities

movable joint where two adjacent bones are separated by an enclosed fluid-filled cavity

dense form of connective tissue that attaches muscles to bones
