AP Lab Ch 1

Contains collegen fibers, bone, and hydroxyapatite

Very strong and resistant to pulling (like floss); creates a mesh-like scaffold that develops during ossification

Hardened via crystallized calcium phosphate, MG, Na+, K+, and Fl (most minerals taken from diet)

Calcium phosphate complex that is primary mineral component of bone

• Has: High compressive strength (bears weight w/o breaking or bending)
• Poor tensile strength- cant be pulled

• Any marked bony prominence
• Ex: mastoid process

• connection between bones- may or may not permit movement
• ex: suphrahumeral articulation (of shoulder blade) and biipital groove (of humerus) or cartaralige connecting ribs to sternum

• Surface of bone that makes contact (articulates) with another bone to form a joint
• Ex: arm socket and shoulder blade

A projection from the surface of the bone

A large, rough projection (when a tendon attaches)

• Small, round projection
• Ex: articulart tubercle by the zygomatic process

• Very large, rough projection (only on the femur)
• Ex: greater trochanter

• A raised ridge
• Ex: on front of scapula

• Immovable joint between 2 bones; usually on skull
• Ex: Coronal suture

• Rouded protuberances on each side of the ankle
• Ex: medial malleolus

• Large, smooth and rounded surface for articulation
• Ex: occipital condyle

“above the condyle”; a projection to the next condyle; tendons usually attach to it

• An elongated, raised surface
• Ex: the femur

• Prominent, narrow ridge
• Ex: illac crest on hip bone

Small, flat and shallow surface for articulation; seen a lot between ribs and spine

• Round passageway through a bone
• Ex: Foramen magnum

• Flattened, shallow, depression
• Ex: subscapular fossa

• Passageway through a bone
• Ex: Carotid canal

Passage way through a bone; longer than a canal and mostly used w/ auditory

Cavity or hollow space in a bone; results in a lighter skull and creates residences chambers to change sound

• A groove or furrow
• Ex: longitudinal fissure ( separates left and right hemisphere of brain)

• Deep narrow depression
• Ex: intertubercular sulcus in humerus- for tendon to run through

• A slender projection from the back of a vertebra
• Ex: what you feel when you run your hand down your spine

Top and bottom of long bones

Middle of long bones

Bone which forms from epiphyseal plate (growth plate) after puberty

• A projection at the end of an elongated bone
• Ex: femoral head

• A narrow part of the bone typically below the head
• Ex: femoral neck

• Surrounds the longitunal axis of the body
• Ex: Head, ribs, coccyx

• Appendages and their attachments to the axial skeleton
• Ex: hips, arms, legs
