18
Q

Head

A

Bony expansion carried on a narrow neck

19
Q

Facet

A

Smooth, nearly flat articular surface

20
Q

Condyle

A

Rounded articular projection

Often articulates with a corresponding fossa

21
Q

Ramus

A

Arm like bar of bone.

22
Q

Foramen

A

Round or oval opening through a bone

23
Q

Groove

24
Fissure
Narrow slit like opening
25
Notch
Indentation at the edge of a structure
26
Fossa
Shallow basin like depression in a bone | Often serving as an articular surface
27
Meatus
Canal like passage way
28
Sinus
Bone cavity filled with air and lined with mucous membrane
29
Diaphysis
Shaft
30
Periosteum
Fibrous membrane covering
31
Perforating collagen fiber bundles
Sharpey's fibers | Fibers of the periosteum
32
Osteoblasts
Bone forming cells
33
Osteoclasts
Bone destroying cells
34
Epiphysis
End of the long bone
35
Articular cartilage
Covers epiphysis | hyaline cartilage
36
Epiphyseal plate
Thin area of hyaline cartilage that provides for longitudinal growth during youth Once long bone has stopped growing, these areas are replaced with bone and appear as thin remnants called Epiphyseal lines
37
Chemical composition of bone
Hardness from inorganic calcium salts | Flexibility from organic elements of matrix, particularly collagen fibers
38
Endochondral ossification
Bones of the body form in the embryo by this process | Uses hyaline cartilage bones as patterns for bone formation
39
Steps of ossification
Blood vessels invade perichondrium, convert it to periosteum Osteoblasts secrete bone matrix around hyaline cartilage model Cartilage in center calcifies, then hollows forming internal cavity Periosteal bud invades cavity and forms spongy bone
40
Hyaline cartilage
Most skeletal cartilages are composed of this | Sturdy support with some give
41
Elastic cartilage
More elastic fibers More flexible, more bending External ear and epiglottis
42
Fibrocartilage
Rows of chondrocytes alternating with rows of thick collagen fibers Withstands heavy compression Intervertebral disks and cartilage of knee joint
