How many bones do we make up?
there 206 bones
true or false: Bones are considered and organ
true
Functions of the bones
Framework, Protection, Levers, Production (red & white blood cells and platelets) and storage
Framework
supports the bodies fat, muscles and skin
Protection
bones surround our vital organ’s, skull protects the brain and rib cage protect lungs
Levers
theyre attached to muscles to provide movement
Production
called hemopoiesis or hematopoiesis
Storage
bones that store most of the cranium
Types of bone
Flat and Long bones
Flat bones
protect internal organs like the brain, heart and pelvic organs
Ex. Cranium-brain, Sternum-ribs and Scapula
Long bones
supports weight and facilitates movement
Ex. Femur (longest bone)
Parts of the skeletal system
Axial and Appendicular
Axial
is made up of the main trunk, (chest, abdomen, pelvis, and back) skull, spinal column, ribs & breast bone
Appendicular
the extremities, (arms or legs) shoulder girdle, arm bones, pelvic girdle and leg bones
The shoulder is made up of -
2 clavicles and the scapula
Bones of each arm
Humerus, Ulna, Carpal, Metacarpals, Phalanges
Where is the Humerus
upper arm radius to lower arm on the thumb side (1 on each side)
Where is the Ulna
large bone on lower arm with a projection (1 on each side)
What’s the Olecranon process
the elbow area (1 on each side)
Where and the Caparls
the wrist area (8 carpals)
Where are the metacarpals
palm of the hand (5 meta)
What are the Phalanges
the fingers (3 each) & thumbs (2 each) (14)
Bones of each leg
Femur, Patella, Tibia, Fibula, Tarsals, Metatarsals, Phalanges
Where is the Femur
thigh (longest bone in our body)
Where’s the Patella
knee cap area
Where’s the Tibia
larger bone of the lower leg or shin
