Motor system Flashcards
The skeletal framework of bones supporting and protecting vital organs. Skull, ribcage spine
axial skeleton
The skeletal framework consisting of the bones of the limbs and their attachments to the axial skeleton, facilitating movement and mobility
appendicular skeleton
Bone type: compact and spongy
dense and cancellous
Cylindrical shaft of a bone, providing support and serving as the primary site for bone growth and mineralization. Compact bone is found here.
diaphysis
Structure of compact bone composed of rings of bone matrix surrounding a central canal, containing blood vessels and nerves
osteons
Bone cells embedded in the bone matrix, responsible for maintaining bone tissue by participating in bone remodeling processes. Found in cavities (lacunae) of osteons surrounding blood vessels.
Osteocytes
Microscopic channels that radiate from lacunae in osteons, allowing osteocytes to communicate.
Canaliculi
Where is Spongy bone found in relation to a bone?
epiphyses
Branching bony structures within cancellous bone, providing structural support.
trabeculae
Where is marrow found
In the shaft of long bones and between the trabeculae of spongy bone
What type of marrow produces red and white blood cells by haemopoiesis
Active
What type of marrow is inactive
Yellow
Bone cells that remove and build bone (2 words)
osteoclasts and osteoblasts
Appendicular skeleton has freely moveable joints. What are they called?
Synovial
What allows freely moving joints (synovial) be movable
hyaline cartilage and synovial fluid
