The Musculoskeletal System Flashcards
Osseous tissue
Another name for bone tissue
Ossification
Process of bone formation
Osteoblast
Bone cell that forms bone tissue. Also known as immature bone cell
Osteoclast
Bone cells that absorbs and removes tissue. Also known as phagocyte of bone
Osteocyte
Bone cell
Articulate cartilage
Thin layer of cartilage covering the surface of bones at a joint
Calcium
The most abundant mineral in the body. When combined with phosphorus it forms calcium phosphate, which is the principal calcium salt and hard material found in bones and teeth
Cancellous bone
Spongy or porous bone found at the ends of long bones and in the inner portions of long bones
Collagen
Structural protein making up the white fibrous strands found in bone
Compact bone
Hard, dense bone tissue that forms the outer layer of bone. Also known as cortical bone
Diaphysis
The shaft of a long bone. The plural is diaphyses
Endosteum
The inner lining of bone. This forms the lining of the medullary cavity
Epiphyseal plate
Cartilaginous region of long bones where lengthwise growth takes place. This is also known as the physis or growth plate
Epiphysis
Each end of the long bone. It is composed of cancellous bone and covered with articular cartilage. The plural I’d epiphyses
Medullary cavity
Central, hollowed-out portion in the shaft of a long bone that contains yellow bone marrow
Metaphysics
The flared portion of a long bone between the epiphyseal plate and diaphysis
Periosteum
Membrane surrounding bone. This fibrous tissue contains blood vessels and nerves
Red bone marrow
Found in cancellous bone and its site of hematopoiesis (blood formation)
Yellow bone marrow
Found in disphysis of bone and consists of fatty tissue
Acetabulum
Cup-like depression in the pelvis that creates the hip joint
Bone head
Rounded articular process separated from the shaft of the bone by a neck. The bone head is usually covered in articular cartilage. Examples include the femoral head and numeral head
Condyle
Knuckle-like projections at the distal end of some long bones. They are usually covered by articular cartilage articulate with other bones. Examples include the femoral and numeral condyles
Crest
High projection or border projection of a bone. An example is the crest of the ilium
Foramen
A hole in bone that allows for the passage of nerves and vessels. Examples include the obturator foramen and the foramen magnum
Fossa
Shallow cavity or depression in bone. An example would be the trochanteric fossa which lies between the greater and lesser trochanter
Groove
A narrow linear depression. Also known as a sulcus. An example is the bicipital groove on the humerus
Olecranon
Bony process at the proximal end of the ulna
