D312 Skeletal System: Questions with 100% correct
answers
The 4 types of bone cells?
osteogenic cells, osteoblasts, osteocytes, osteoclasts
Compact bone
Hard, dense bone tissue that is beneath the outer membrane of a bone
Function: Provide support and protection. Stronger than spongy bone
Spongy bone(Cancellous)
Layer of bone tissue having many small spaces and found just inside the layer of compact bone.
Contains osteocytes
ossification
process of bone formation
cartilage
Connective tissue found on the skeleton in area where flexibility and smooth surfaces support
movement.
Osteogenic cells
Undifferentiated w/ high mitotic activity, and are the only bone cells that divide. stem cell
osteoblast
Bone growth
Growing portion including periosteum and endosteum
, Osteocytes
Mature bone cell. It is the most common type of bone cell.
Maintain mineral concentration
Osteoclasts Cells
Bone resorption and breakdown.
Bone surfaces and at sites of old, injured, or unneeded bone
Lacuna
Space where the osteocyte is located
diagram of spongy bone
Spongy bone is composed of trabeculae that contain the osteocytes. Red marrow fills the spaces
in some bones.
Lamelle
They are rings of calcified extracellular matrix.
It allows the bone to withstand torison pressure
Lacunae
small cavities in bone thats located b/w the lamella and contain osteocytes
tracbeculae
Found in spongy bones, forms along lines of stress to provide strength of bones
What is the relationship b/w bone and cartilage?
