Skeletal System

Front 1

Functions of the skeletal system

Back 1

Protects organs
Assists in movement
Stones minerals
Supports body

Front 2

What kind of tissue is bone?

Back 2

Connective

Front 3

Elastic Cartilage

Back 3

Thread like network of elastic fibres within the matrix.
Provides strength and elasticity maintains structure.
Examples: Outer ear

Front 4

Fibrocartilage

Back 4

-Strongest type of cartilage
Alternating layers of hyaline cartilage matrix and thick layers of dense collagen fibres.
Examples: Found in vertebral discs, joints and ligaments

Front 5

Hyaline

Back 5

Glassy appearacnce fine collagen fibres.
Weakest of the 3
ribs, nose, trachea

Front 11

Compact bone

Back 11

Dense, compact, small holes
Found on outer part of bone

Front 12

Spongy bone

Back 12

Weaker, very porous, found in inner part of bone

Front 13

Parts of bone

Back 13

Articular cartilage
Diaphysis
Epiphyseal plate
Epiphysis
Medullary cavity
Periostem

Front 14

Articular cartilage

Back 14

Smooth white tissue that covers the ends of bone to form joints

Front 15

Diaphysis

Back 15

Hollow center portion of bone made of compact tissue

Front 16

Epiphyseal plate

Back 16

Thin layer of cartilage. shaft of plate

Front 17

Epiphysis

Back 17

Wide ends of a long bone

Front 18

Medullary cavity

Back 18

hollow space within the shaft of the long bone filled with marrow

Front 19

Periosteum

Back 19

Outermost fibrous layer that supplies blood and nerves to the bone

Front 20

Red Marrow

Back 20

Mostly found in children
required in the formation of RBC's
red from hemoglobin

Front 21

Yellow Marrow

Back 21

Produces fat, cartilage and bone.
Yellow from high number of fat cells

Front 22

Function of inorganic salts ans collagen in bone

Back 22

The hardness and strength of a bone is determined by inorganic salts such as calcium and collagen

Front 23

Ossification

Back 23

The bone remodeling process in which connective tissues are turned into bone tissue

Front 24

Bone growth hormone

Back 24

Growth hormone from the anterior pituitary

Front 25

Osteocytes

Back 25

star shaped cells found in bones

Front 26

Osteoblasts

Back 26

Bone making cell. Produces matrix and synthesizes

Front 27

Osteoclasts

Back 27

Breaks down bone and is responsible for reabsorption

Front 28

Hormone in bone formation

Back 28

Parathyroid hormone effects bone formation, reabsorption and will also work to raise blood calcium levels by stimulating osteoclasts

Front 29

What are the parts of a joint?(6)

Back 29

Aticular Cartilage- tough elastic connective tissue that can be turned into bone.

Joint Capsule- thin fibrous sac containing fluid used for joint lubrication
Ligament-Tough band of connective tissue that holds two bones together
Synovial cavity- space between two bones filled with fluid
Synovial fluid- found in synovial cavities that reduces friction (lubrication
Synovial Membrane- Thin membrane of joints comprised of smooth connective tissue and secreted synovial fluid
