-
Osseous tissue Matrix
Contains collegen fibers, bone, and hydroxyapatite
-
Collagen fibers
Very strong and resistant to pulling (like floss); creates a mesh-like scaffold that develops during ossification
-
Bone
Hardened via crystallized calcium phosphate, MG, Na+, K+, and Fl (most minerals taken from diet)
-
Hydroxyapatite
Calcium phosphate complex that is primary mineral component of bone
-
Osseous Tissue
- Has: High compressive strength (bears weight w/o breaking or bending)
- Poor tensile strength- cant be pulled
-
Process
- Any marked bony prominence
- Ex: mastoid process
-
Articulation
- 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
-
Articular Process
- Surface of bone that makes contact (articulates) with another bone to form a joint
- Ex: arm socket and shoulder blade
-
Eminence
A projection from the surface of the bone
-
Tuberosity
A large, rough projection (when a tendon attaches)
-
Tubercle
- Small, round projection
- Ex: articulart tubercle by the zygomatic process
-
Trochanter
- Very large, rough projection (only on the femur)
- Ex: greater trochanter
-
Spine
- A raised ridge
- Ex: on front of scapula
-
Suture
- Immovable joint between 2 bones; usually on skull
- Ex: Coronal suture
-
Malleolus
- Rouded protuberances on each side of the ankle
- Ex: medial malleolus
-
Condyle
- Large, smooth and rounded surface for articulation
- Ex: occipital condyle
-
Epicondyle
“above the condyle”; a projection to the next condyle; tendons usually attach to it
-
Line/Ridge
- An elongated, raised surface
- Ex: the femur
-
Crest
- Prominent, narrow ridge
- Ex: illac crest on hip bone
-
Facet
Small, flat and shallow surface for articulation; seen a lot between ribs and spine
-
Foramen
- Round passageway through a bone
- Ex: Foramen magnum
-
Fossa
- Flattened, shallow, depression
- Ex: subscapular fossa
-
Canal
- Passageway through a bone
- Ex: Carotid canal
-
Meatus
Passage way through a bone; longer than a canal and mostly used w/ auditory
-
Sinus
Cavity or hollow space in a bone; results in a lighter skull and creates residences chambers to change sound
-
Fissure
- A groove or furrow
- Ex: longitudinal fissure ( separates left and right hemisphere of brain)
-
Sulcus
- Deep narrow depression
- Ex: intertubercular sulcus in humerus- for tendon to run through
-
Spinous Process
- A slender projection from the back of a vertebra
- Ex: what you feel when you run your hand down your spine
-
Epiphysis
Top and bottom of long bones
-
Diaphysis
Middle of long bones
-
Epiphyseal line
Bone which forms from epiphyseal plate (growth plate) after puberty
-
Head
- A projection at the end of an elongated bone
- Ex: femoral head
-
Neck
- A narrow part of the bone typically below the head
- Ex: femoral neck
-
Axis
- Surrounds the longitunal axis of the body
- Ex: Head, ribs, coccyx
-
Appendicualr
- Appendages and their attachments to the axial skeleton
- Ex: hips, arms, legs
-
