Periosteum
Tough fibrous tissue that forms the outermost covering of bone
Peri- surrounding
Oste- bone
Compact bone
Also know as cortical bone
dense, hard, very strong bone that forma protective outer layer of bones
Spongy bone
Known as cancellous bone
Lighter, not as strong,
Commonly found in the ends and inner portions of long bones
Red bone marrow is located with spongy bone
Medullary cavity
Central cavity located in the shaft of long bone
Medullary means pertaining to inner section
Endosteum
The tissue that lines the medullary cavity
End- within
Oste- bone
Um- noun ending
Red bone marrow
Located within spongy bone,
Hemopoietic tissue that manufactures red blood cells, hemoglobin, white blood cells, and thrombocytes
Hemopoietic
Pertaining to the formation of blood cells
Hem/o- blood
Poietic- pertaining to formation
Yellow bone marrow
Fat storage area, composed of fat cells and is located in the medullary cavity of long bones
Cartilage
Smooth, rubbery, blue-white connective tissue, shock absorber between bones, more elastic then bone
Articular cartilage
Covers the surfaces of bones where they come together to form joints
Makes move joint movement possible and protects the bone from rubbing agains each other
Meniscus
The curved fibrous cartilage found in some joints, such as the knee and the temporomandibular joint of the jaw
Diaphysis
Shaft of a long bone
Epiphyses
Wider ends of long bone
Covered with articular cartilage
Foramen
Opening in a bone through which blood vessels, nerves, and ligaments pass
Process
Normal projection on the surface of a bone
Most commonly serves as an attachment for a muscle or tendon
Sticks out
Joints
Also known as articulations
Place of union between two or more bones
Fibrous joints
Consisting of inflexible later o dense connective tissue,
Hold bones tightly together
In adults known as sultures
Do not allow any movement
Fontanelles
Known as the soft spots
Normally present on the skull of a newborn
Cartilaginous joints
Allow only slight movement and consist of bones connected entirely by cartilage
Synovial joints
Where two bones articulate to permit a verity of motions
Two types of synovial joints
Ball and socket joints - allow. Wide range of movement in many directions
Hinge joints - allow movement primarily in one direction or plane
Synovial capsule
Outermost layer of strong fibrous tissue
Resembles a sleeve as it surrounds the joint
Synovial membrane
Lines the capsule and secretes synovial fluid
Synovial fluid
Flows within the synovial cavity
Acts as a lubricant to make the smooth movement of the joint possible
Ligaments
Are bands of fibrous tissue that form joints by connecting one bone to another bone or by joining a bone cartilage
Bursa
Fibrous sac that acts as a cushion to ease movement in areas that are subject to friction
Axial skeleton
Protects major organs of the nervous, respiratory, and circulatory systems
80 bones
Appendicular skeleton
Makes body movement possible and also protects the organs of digestion, excretion, and reproduction
126 bones
