Bone Test Flashcards
Functions of Skeletal System
Support
Protection
Movement
Storage
Hematopoiesis- Blood cell
formation occurs in
red marrow
Diaphysis (DIAmond)
Shaft; composed of compact bone
Epiphysis (End)
End of bone; composed of mostly spongy bone
Shapes of bones
Long- Femur
Short- Lateral, Intermediate, medial cuneiform
Flat- Sternum
Irregular- Vertebra
Sesamoid- Patella
Osteoblasts (BLASTS)
Bone destroying cells (BLASTS)
Osteocyte (Old)
Mature bone cells
Purpose of Articular cartilage (ART = SMOOTH)
Cover Epiphysis for smooth movement (Art= paint= smooth)
Purpose of serous fluid (Sofa)
To lubrictae anf cushion organs and surfaces of the body
Purpose of elastic cartialige
Supports parts of the body that need to bend and move to function
Red bone marrow location and function
Location- In cavities of spongy bone in flat bones
Function- Site of hematopoiesis (Blood cell
formation occurs in
red marrow)
Remodeling
Breaking down and reforming of bone that occurs THROUGHOUT LIFE to maintain proportion and strength as well as healthy calcium levels
Yellow bone marrow location and function
Location- in medullary cavity
Function- fat storage
Where are the “soft spots”

Age of closed fotenels
18 months to 2 years
Lordosis (LOWER)
an exaggerated inwarad curve of the spine that effects the lower back

Cleft Palate
Midline of the hard palate does not close
Purpose of fontanels
Alloes for growth of brain and skull
Largest fontanels
Anterior Fontanelle
Kyphosis
An exaggerated, foward rounding of the upper back
5 vertebral regions
