1

Two types of skeleton

Axial and appendicular

2

How many bones in Axial & list the main bones

Axial: 80 Main bones are skull, laryngeal skeleton, vertebral column, and thoracic cage

3

How many bones in Appendicular & list the main bones

Appendicular: 126 Main bones are Pectoral girdle, arms, forearms, hands, pelvis, legs, feet, and ankles

4

Total bones in human body?

206

5

Functions of the Skeletal System

Support and protection
Body Movement
Produces blood cells
Storage of minerals and fats

6

(5) The classifications of bones

Long, Short, Flat, Irregular, Seasomied

7

Epiphysis

End of both sides of a given bone

8

Diaphysis

The hollow inside of your bone

9

Articular Cartilage

Articular cartilage is the smooth, white tissue that covers the ends of bones where they come together to form joints. Protects bone from too much friction

10

Periosteum

The periosteum helps bone growth. The outer periosteum layer contributes to the blood supply of your bones and the surrounding muscles.

11

Medullary Cavity

hollow chamber filled with bone marrow

12

(2) Functions of Red/Yellow Bone Marrow

Red marrow produces blood and Yellow marrow stores fat

13

Compact Bone Tissue

Compact is solid w no holes (wall of the diaphysis)

14

Spongy Bone Tissue

Spongy has lots of holes in it (cancellous, epiphysis) - red marrow

15

Flexion/Extension

Flexion is a movement that decreases the angle between two body parts. Extension isa movement that increases the angle between two body parts

16

Abduction/Adduction/Circumduction

Abduction is the movement away from midline of body. Adduction is the movement towards the midline of body. Circumduction is the movement of a body region in a circular manner.

17

Rotation

Rotation is the movement of the vertebral column, at a pivot joint, or at a ball-and-socket joint

18

Supination/Pronation

Supination is hands facing up with bend in arm. Pronation is hands facing down like a push up

19

Dorsiflexion/Plantar Flexion

Dorsiflexion is toes in the air and Plantar is foot towards the ground

20

Inversion/Eversion

Inversion is feet facing towards midline of the body Eversion is feet facing away from the midline of the body

21

Protraction/Retraction

Protraction is shoulders moving forward and Retraction is shoulders back

22

Depression/Elevation

Depression is shoulders going down and Elevation is them going up

23

Opposition/Reposition

Opposition is thumb and index touching and reposition is back to normal

24

How many bones are in the cranium

The eight bones of the cranium form the “vault” that encloses the brain. They include the frontal, parietal, occipital, temporal, sphenoid and ethmoid bones

25

What is the only movable bone in your skull

The only bone in your skull that forms freely movable joints is your mandible, or jawbone.

26

What are the five vertebral regions (from superior to inferior)

Cervical, Thoracic, Lumbar, Sacral, Coccygeal

27

How many vertebrae are in cervical

7 vertebrae

28

How many vertebrae are in thoracic

12 vertebrae

29

How many vertebrae are in lumbar

5 vertebrae

30

Scoliosis

Lateral curvature of spine
