Bone Structure And Bone Fractures Flashcards
Epiphysis
Ends of bone proximal and distal
Metaphysis
Growth zones where epiphyses meet the diaphysis
Epiphyseal disk
A plate of hyaline cartilage that exists at metaphysic during growth years (growth plate)
Medullary cavity
Hello chamber along diathesis hold the yellow marrow
Endosteum
Membrane that lines the medulary cavity and is continuous with the haversian canals
Yellow marrow
Fatty material that fills the medullary cavity
Red marrow
Phil’s ribs and sternum vertebrae calcaneous humorous and femur in adults
Periosteum
Top covering envelope in the surfaces of the entire bone except areas of articulation or the outer covering
Articular cartilage
Covers each epiphysis which contact adjacent bones
Volkmanns canal
Canal for blood vessels that run horizontal and spongy bone
Haversian Canal
Can now for blood vessels that run along the length of compact bone
Osteoblast
Creates bone
Osteoclast
Breaks down old bones
Hematopeosis
Red marrow produces red blood cells and white blood cells
Osteoporosis
Loss of bone mineral density osteoblast activity slows down well osteoclast activity increases
Closed or simple bone fracture
Bones stay within the confines of the skin
Open or compound fracture
Bone and stick through the skin
Incomplete fracture
Greenstick fracture it doesn’t break through the full thickness of the bone
Fissured fracture
Crack that goes along the length of the bone
Complete fracture
Breaks through the full thickness of the bone
Transverse fracture
Across the long axis of the bone
Oblique fracture
On an angle or diagonal across the bone
Spiral fracture
From rotational factors bone will break in multiple places looking like a spiral
Segmental fracture
Breaks in three or more pieces
