2. How many bones are in an adult human body?
206

3. Function of the Skeletal System
Support- framework that supports body and cradles its soft organs
Protection- for delicate organs, heart, lungs, brain
Movement- bones act as levers for muscles
Mineral storage- calcium & phosphate
Blood cell formation- hematopoiesis
(Bone Marrow)

4. Types of Bones
Long Bones- metacarpals, metatarsals, phalangies, humerus, ulna, radius, tibia, fibula & femur
Short Bones- carpals, tarsals
Flat Bones- rib, scapula, skull, sternum
Irregular Bones- vertebrae, some facial bones
Sesamoid- patella

5. Bone Classification

6. Type of Bone Joints
Pivot (Ex: neck between C1 and C2 vertebrae- rotation, flexion, extension, abduction, adduction)
Ball & Socket (Ex: shoulder, hip- flexion, extension, abduction, adduction, rotation,)
Hinge (Ex: elbow, knee- flexion, extension)
Saddle (Ex: thumb- flexion, extension, adduction, abduction)
Gliding (Ex: ankle- flexion extension, rotation)
Condyloid (Ex: wrist- flexion, extension, abduction adduction)
