A/p: Anatomy Of A Long Bone

Front 1

A typical long bone has what two regions?

Back 1

diaphysis
epiphysis

Front 2

The long cylindrical shaft of a long bone is the

Back 2

diaphysis

Front 3

The hollow space within the center of the long bone shaft is the

Back 3

medullary cavity

Front 4

What color marrow is dominant in the medullary cavity?

Back 4

yellow

Front 5

Yellow marrow is filled with

Back 5

fat

Front 6

Blood cells formed in the medullary cavity can exit the bone and enter the bloodstream via what two systems?

Back 6

Haversian canals
Volkmann's canals

Front 7

Minute vascular canals that run longitudinaly through a long bone are called

Back 7

Haversian canals

Front 8

Canals that run horizontally through a long bone (and connect the other type of canals) are called

Back 8

Volkmann's canals

Front 9

The sheath around the diaphysis is called the

Back 9

periosteum

Front 10

The long bone's "life-support system" containing vessels, nerves, and osteoblasts is called the

Back 10

periosteum

Front 11

This is a tough membrane that interconnects the periosteum of certain bones

Back 11

interosseus membrane (aka interosseus ligament)

Front 12

The two ends of a long bone are the

Back 12

epiphyses

Front 13

The areas of a long bone where it grows in length are the

Back 13

epiphyses

Front 14

An epiphysis is covered with

Back 14

articular cartilage (hyaline cartilage)

Front 15

This area contains the growth portion of a long bone

Back 15

metaphysis

Front 16

Depending on the bone's age, the metapysis can contain one of these:

Back 16

epiphyseal plate (immature bone)
epiphyseal line (when growth is complete)

Front 17

This is a thin layer of cartilage between the epiphysis and the diaphysis , give three names:

Back 17

epiphyseal plate
epiphysea disk
growth plate

Front 18

osteoblasts are found in what specific layer?

Back 18

periosteum

Front 19

bone cells that are embedded in the bone matrix are the

Back 19

osteocytes

Front 20

Cells that break down bone tissue and often help repair bone are the

Back 20

osteoclasts

Front 21

five types of CT in the skeletal system:

Back 21

osseus tissue
cartilage
ligaments
periosteum
bone marrow

Front 22

two types of osseus tissue are

Back 22

spongy bone
compact bone

Front 23

spongy bone is found where, in long bones?

Back 23

center
ends

Front 24

compact bone is found where in long bones?

Back 24

the periphery, and a portion of the shaft bulk in some bones, eg the humerus

Front 25

The type of bone formation process found on the roof and sides of the skull is:

Back 25

intramembranous ossification

Front 26

The type of bone formation found in the bones of the extremities is:

Back 26

intracartilaginous ossification (aka endochondral...)

Front 27

Another term for synarthrotic joints is

Back 27

fibrous joints

Front 28

Another term for amphiarthrotic joints is

Back 28

cartilaginous joints

Front 29

Another term for diarthrotic joints is

Back 29

synovial joints

Front 30

Joints which allow movement in three dimensions are called

Back 30

diarthrotic

Front 31

Joints that are sligtly movable are called

Back 31

amphiarthrotic

Front 32

Joints that are extremely limited in movement are called

Back 32

synarthrotic
