Flashcards in Chapter 6 Deck (32):
1

Surface features, can yield an abundance of anatomical information.

Bone Markings

2

The shaft of a long bone.

Diaphysis

3

The head of a long bone.

Epiphysis

4

The region of a long bone between the epiphysis and diaphysis, corresponding to the location of the epiphyseal cartilage of the developing bone.

Metaphysis

5

The space within a bone that contains the marrow.

Medullary Cavity

6

The outer layer or portion of an organ or bone.

Cortex

7

Calcium phosphate interacts with calcium hydroxide to form crystals of this.

Hydroxyapatite

8

A bone cell responsible for the maintenance and turnover of the mineral content of the surrounding bone.

Osteocytes

9

Concentric layers; the concentric lairs of bone within an osteon.

Lamellae

10

Microscopic passageways between cell.

Canaliculi

11

A cell that produces the fibers and matrix of bone.

Osteoblasts

12

The process of producing new bone matrix.

Osteogenesis

13

The organic matrix before calcium salts are deposited.

Osteoid

14

A cell that dissolves the fibers and matrix of bone.

Osteoclasts

15

The basic histological unit of compact bone, consisting of osteocytes organized around a central canal and separated by concentric lamellae.

Osteon

16

A connective tissue partition that subdivides an organ.

Trabeculae

17

Responsible for blood cell formation.

Red Bone Marrow

18

Adipose tissue important as an energy reserve.

Yellow Bone Marrow

19

The layer that surrounds a bone, consisting of an outer fibrous region and inner cellular region.

Periosteium

20

An incomplete cellular lining on the inner surfaces of bones.

Endosteum

21

The formation of bone.

Ossification

22

The deposition of calcium salts within a tissue.

Calcification

23

The conversion of a cartilaginous model to bone.

Endochondral Ossification

24

The cartilage pad that covers the surface of a bone inside a joint cavity.

Articular Cartilage

25

The cartilaginous region between the epiphysis and the diaphysis of a growing bone.

Epiphyseal Cartilage

26

The former location of the epiphyseal cartilage is detectable in x-rays is known as this. It remains after epiphyseal growth has ended.

Epiphyseal Line

27

The organic and mineral components of the bone matrix are continuously being recycled and renewed through this process.

Remodeling

28

A large blood clot.

Fracture Hematoma

29

An enlarged collar of cartilage and bone, forms and encircles a bone tat the level of the fracture.

External Callus

30

Organizes within the medullary cavity and between the broken ends of the shaft.

Internal Callus

31

When the reduction in bone mass is sufficient to compromise normal function.

Osteoporosis

32

Inadequate ossification is called _____, and all of us become slightly _____ as we age.

Osteopenia
