- Cranium
- Sternum
- Ribs
- Vertebral Column

whoops
2 of 23
Appendicular skeleton - movement
- scapula
- clavicle
- humerous
- radius
- ulna
- carpals
- metacarpals
- phalanxes
- illium, ischium, pubis
- femur
- patella
- tibia
- fibula
- tarsals
- metatarsals
3 of 23
Functions - shape
- gives us our unique shape
- rigid frame
- your bones give you shape
- support soft tissues
4 of 23
Functions - support
- support for organs
- something for them to attach or suspend
5 of 23
Functions - protection
- protects vital organs in the body
6 of 23
Functions - movement
- allows movement of the body as a whole
- bones act as levers and also form joints that allow muscles to pull on them and produce joint movements.
7 of 23
Functions - mineral storage
- the bones themselves are made of minerals and act as a mineral store for calcium and phosphorus.
8 of 23
Functions - blood cell production
- certain bones in the skeleton contain red bone marrow.
- bone marrow produces red blood cells, white blood cells and platelets
EXAMPLES: pelvis, sternum, vertebrae, clavicle
9 of 23
Bone type - sesamoid
- protects tendons from stress and wear
- holds the tendon slightly further away from the joint, this increases it's movement
BONES: patella
10 of 23
Bone type - irregular
- protect the spinal cord
- protect internal organs
BONES: vertebral column, talus
11 of 23
Bone type - short
- provide stability and some movement
BONES: carpals, tarsals
12 of 23
Bone type - flat
- protect vital organs
- provide large areas of attachment for muscles
BONES: cranium, sternum, ribs, scapula, pelvis
13 of 23
Bone type - long
- support the weight of the body and facilitate movement.
- mostly located in the appendicular skeleton
BONES: clavicle, humerous, radius, ulna, tibia, fibula, femur, metacarpals, metatarsals, phalanges
14 of 23
Joint type - fixed/fused
- no movement is possible at these joints
BONES: skull
15 of 23
Joint type - Cartilaginous
- slightly moveable
- connected by cartilage
16 of 23
Joint type - synovial
- large range of movement
- 6 different types
17 of 23
Synovial
Hinge
- allow for flexion and extension
JOINTS: elbow, knee
18 of 23
Synovial
Ball and socket
- freely moving, can rotate on any axis
JOINTS: hip, shoulder
19 of 23
Synovial
Gliding
- move against each other on a single plane
JOINTS: vertebral column
20 of 23
Synovial
Condyloid
- allows for circular motion, flexion and extension
21 of 23
Synovial
Saddle
- allows for flexion, extension and other movements but no rotation
JOINTS: thumb
22 of 23
Synovial
Pivot
- Provides rotation
