What are the four types of bones?
Long bone, short bone, flat bone, and irregular bone.
Structure of a long bone.
Longer than wider. Shaft made primarily of cortical ‘compact’ bone, two bulky ends with trabecular ‘spongy’ bone.
Structure of a short bone.
Same length and width/wider then longer. Consist mostly of trabecular ‘spongy’ bone with thin layer of cortical ‘compact’ bone.
Structure of a flat bone.
Mostly flat and curved. Layer of trabecular bone with a thin layer of cortical bone.
Structure of an irregular bone.
Come in various shapes and sizes. Layer of trabecular bone with a thin layer of cortical bone.
What are the four layers of the bone?
Periosteum - outer membrane.
Cortical - dense outer layer.
Trabecular - spongy struts and plates.
Medullary - bone marrow middle.
_ is the outer most layer of the bone.
Periosteum
_ is the dense outer layer of the bone.
