Skeletal system Flashcards
capsule
structure surrounding the synovial joint made up of fib
Compact bone consists of units called
Haversian systems or osteons
Concentric layers of bone
lamellae
Concentric layers of bone called lamellae surround a central….
Haversian canal
Haversian canal carries
nerves, blood and lymph vessels.
Between the lamellae layers are
lacunae
lacunae contain - O
osteocytes
canaliculi
Tiny canals that run between each lacunae to allow adjacent cells to make contact and pass materials from cell to cell
Haversian Systems run..
parallel to the long axis of the bone, giving maximum strength
The function of the skeletal system - P
Protect internal organs
The function of the skeletal system- Su
Support body structures
The function of the skeletal system- A
Provide for attachment of the muscles to allow movement (articulation)
The function of the skeletal system- St
Storage of: Minerals (calcium, phosphorus, sodium & potassium) &Fat
The function of the skeletal system- F
Formation of blood cells (in red bone marrow)
Gliding joints
allow movement back and forth in any direction (restricted by ligaments)
