Skeletal System #1 WK3 L2 Flashcards
WHAT ARE THE FUNCTIONS OF THE SKELETON?
PROTECTION MOVEMENT SUPPORT BLOOD CELL PRODUCTION ELECTROLYTE BALANCE
HOW DOES THE SKELETON ASSIST IN PROTECTION?
FORMS A COVERING FOR VITAL ORGANS
HOW DOES THE SKELETON ASSIST IN MOVEMENT?
MUCELS ATTACH TO BONE FOR MOVEMENT
HOW DOES THE SKELETON ASSIST IN SUPPORT?
BONES PROVIDE STRUCTURAL FRAME WORK
HOW DOES THE SKELETON ASSIST IN BLOOD CELL PRODUCTION?
ERETHROCYTES, LEUKOCYTES, THROMBOCYTES MADE IN RED BONE MARROW
HOW DOES THE SKELETON ASSIST IN ELECTROLYTE BALANCE?
SKELETON STORES CALCIUM AND OHSOHATE IONS AND RELEASES THEM WHEN NEEDED
WHAT IS A SUTURE
A JOIN THAT CONNECTS TO BONES TOGETHER LIKE THE SKULL
WHAT ARE THE BONE CELL TYPES?
OSTEOPROGENITOR
OSTEOBLAST
OSTEOCYTE
OSTEOCLAST
WAT ARE OSTEOPROGENITORS?
STEM CELLS FOUND IN MEMBRANEOUS PERIOSTEUM AND ENDOSTEUM
ABLE TO DIFFERENTIATE INTO SECOND CELL TYPE WHEN STIMULATED
WHAT ARE OSTEOBLASTS?
BONE BUILDING CELLS THAT SECRETE BONE MATRIX
WHAT ARE OSTECYTES?
OSTEYOCYTES ARE OLD OSTEBLASTS THAT HAVE BECOME COMPLETELY SURROUNDED IN MATRIX
CANALIQUILI FORM FORM FROM THE MATRIX BUILDUP TO MAKE CHANNELS FOR COMMUNICATION
WHAT ARE OSTEOCLASTS?
BREAK DOWN BONE AND REABSORBS IT
WHAT IS THE DRY WEIGHT OF BONE?
1/3 ORGANIC
2/3 INORGANIC
WHAT IS ORGANIC MATTER?
CONSISTS OF COLLAGEN AND PROTEOGLYCANS
WHAT IS INORGANIC MATTER?
85% HYDROXYAPETIE (CALCIUM AND PHOSPHATE CRYSTAL)
10% CALCIUM CARBONATE AND OTHER MINERALS LIKE POTASSIUM, FLOURIDE, AND MAGNESIUM
