A and P of the Skeletal System - Bones: Bone Projections and Depressions - Skeleton: Axial Skeleton/Appendicular Skeleton - Joints Flashcards
Bone Marrow
Soft tissue found inside cavities in bones; produces blood cells
Ligaments
Very strong bands of connective tissue that bind bones together at a joint
Bone
Type of connective tissue and organ of musculoskeletal system; they provide support for body and serve as sites of muscle attachements
Skeleton
Bones forming framework for body; site for skeletal muscle attachments
Joint
Point at which two bones meet; provides flexibility
Cartilage
Strong, flexible connective tissue found in several locations in body, such as covering ends of bones in synovial joint, nasal septum, external ear, eustachian tube, larynx, tracheae, bronchi, and intervertebral discs
Osteoblast
Embryonic bone cell
Osseous Tissue
Bony tissue; one of hardest tissues in body
Ossification
Process of bone formation
Osteocyte
Mature bone cells
Articular Cartilage
Layer of cartilage covering ends of bones forming synovial joint
Cancellous Bone
Bony tissue found inside a bone; contains cavities that hold red bone marrow; also called ‘spongy bone’
Compact Bone
Hard exterior surface bone; also called ‘cortical bone’
Cortical Bone
Hard exterior surface bone; also called ‘compact bone’
Diaphysis
Shaft portion of long bone
Epiphysis
Wide ends of a long bone
Flat Bone
Type of bone with thin flattened shape; examples include scapula, ribs, and pelvic bones
Irregular Bones
Type of bone having irregular shape; vertebrae are irregular bones
Long Bone
Type of bone longer than it is wide; examples include femur, humerus, and phalanges
Medullary Cavity
Large open cavity that extends length of shaft of long bone; contains yellow bone marrow
Periosteum
Membrane that covers most bones; contains numerous nerves and lymphatic vessels
Red Bone Marrow
Tissue that manufactures most of blood cells; found in cancellous bone cavities
Short Bone
Type of bone that is roughly cube shaped; carpals are short bones
Spongy Bone
Bony tissue found inside bone; contains cavities that hold red bone marrow; also called ‘cancellous bone’
Yellow Bone Marrow
Located mainly in center of diaphysis of long bones; contains mainly fat cells
Condyle
Refers to rounded portion at end of a bone
Epicondyle
Projection located above or on condyle
Fissure
Deep groove or slit-type opening
Foramen
Passage or opening through bone for nerves and blood vessels
Fossa
Shallow cavity or depression within or on surface of a bone
Head
Large ball-shaped end of a bone; may be separated from shaft of bone by area called neck
Neck
Narrow length of bone that connects ball of ball-and-socket joint to diaphysis of long bone
Process
Projection from surface of a bone
Sinus
Hollow cavity within bone
Trochanter
Large blunt process that provides attachment for tendons and muscles
Tubercle
Small, rounded process that provides attachment for tendons and muscles
