Ossification

The normal process of bone formation

1

Osteoblasts

a cell that secretes the matrix for bone formation.

2

Osteoclasts

a large multinucleate bone cell that absorbs bone tissue during growth and healing.

3

Periosteum

a dense layer of vascular connective tissue enveloping the bones except at the surfaces of the joints.

4

Compact bone

The compact noncancellous portion of bone that consists largely of concentric lamellar osteons and interstitial lamellae.

5

Spongy bone

Bone in which the spicules form a latticework, with interstices filled with embryonic connective tissue or bone marrow

6

Medullary

of or relating to a medulla and especially the medulla oblongata

7

Medullary cavity

The medullary cavity (medulla, innermost part) is the central cavity of bone shafts where red bone marrow and/or yellow bone marrow (adipose tissue) is stored; hence, the medullary cavity is also known as the marrow cavity.

8

Endosteum

is a thin layer of connective tissue that lines the surface of the bony tissue that forms the medullary cavity of long bones.

9

Hemopoietic

the formation of blood or of blood cells in the living body

10

-poietic

Productive

11

Cartilage

a usually translucent somewhat elastic tissue that composes most of the skeleton of vertebrate embryos and except for a small number of structures

12

Articular cartilage

Cartilage that covers the articulate surfaces of bones l

13

Meniscus

A thin fibrous cartilage between the surfaces of some joints

14

Diaphysis

The shaft or central part of a long bone

16

Epiphyses

The end part of a long bone, initially growing separately from the shaft.

17

Foramen

an opening, hole, or passage, especially in a bone.

18

Process

a prominence or projection, as from a bone.

19

Red bone marrow

bone marrow in which the stroma primarily contain the developmental stages of erythrocytes, leukocytes, and megakaryocytes; it is present throughout the skeleton during fetal life and at birth.

20

Yellow bone marrow

Lymphocytes mature in the lymphoid organs (see lymphoid tissue). All other blood-cell formation occurs in red marrow, which also takes part in destruction of old erythrocytes (red blood cells). Yellow bone marrow mainly stores fats.

21

Arthro

joint

22

Chondr

cartilage

23

Myel

bone marrow

24

Oss

bone

25

Chondroma

a benign tumor containing the structural elements of cartilage
