Bones

Tuberosity

A rough elevated surface that marks the attachment of a ligament or tendon

Tubercle

small rounded projection;

Crest

Narrow ridge of bone; usually prominent

Trochanter

Very large, blunt, irregularly shaped process on the femur.

Condyle

Rounded articular projection.

Line

Narrow ridge of bone, less prominant then crest vertically on a long bone or area horizontally on a long bone where a growth plate has closed.

Epicondyle

Raised area on or above a condyle.

Spine

Sharp, slender, often pointed projection.

Process

Any bone prominence.

Head

Bony expansion carried on a narrow neck.

Facet

Smooth, nearly flat articular surface.

Ramus

Armlike bar of bone.

*Groove

Furrow

*Fissure

Irregular elongated hole in a bone

*Foramen

Round or oval opening through a bone.

*Meatus

Canal-like passageway

*canal

canal

*Fossa

Shallow, basin-like depression in a bone, often serving as an articular surface.

Bone markings

Sites of muscle, ligament and tendon attachment, as joint surfaces, or as conduits for blood vessels and nerves.

types of tissue in bone

osseous, nervous, cartilage fibrous connective tissue, muscle and epithelial in blood vessels

types of bone

compact = dense made up of osteons , rigid outer bone

spongy=porous inner bone, small trabeculae of bone and lots of open space

classifications of bone

long =(humerus, femur, phalanges) more long then wide, shaft with head, mostly compact bone

short= (talas, tarsals, carpals) cube like, more spongy

flat= thin, flat, slightly curved (sternum, scapula, ribs, most skull bones)

irregular= all other shapes (vertebra and pelvic girdle)

Perichondrium

Dense irregular connective tissue membrane covering cartilage- delivers nutrients to cartlage via blood vessels

206, 8 cranial ,14 facial

skeletal classification

axial (80) (skull, vertebral, thoracic cage) and appendicular (126) (limbs and girdles)
