Bone cells and Compact/Spongy bone Histology Flashcards
What is the primary function of osteoprogenitor cells?
Osteoprogenitor cells are responsible for developing into osteoblasts.
Fill in the blank: Osteocytes are mature bone cells that maintain ________.
bone tissue
What type of bone cell is primarily responsible for bone resorption?
Osteoclasts
Multiple Choice: Which of the following cells are responsible for the formation of new bone? A) Osteoclasts B) Osteoblasts C) Osteocytes D) Osteoprogenitor
B) Osteoblasts
Describe the role of osteocytes in bone tissue.
Osteocytes maintain bone tissue and communicate with other bone cells to regulate bone remodeling.
What is the origin of osteoclasts?
Osteoclasts originate from the fusion of white blood cells
True or False: Osteoprogenitor cells can be found in the periosteum and endosteum.
True
What is the main difference between osteoblasts and osteoclasts?
Osteoblasts build bone, while osteoclasts reobsorb and break down bone.
What is an osteon?
Compact cylinder of concentric lamellae which makes up compact bone
What is concentric lamellae made up of?
circular rings of calcified extracellular matrix
Where does the central canal run through?
central canal runs through the center of an osteon, housing blood vessels and nerves
When looking at an osteocyte what are the small channels which connect lacunae to each other?
canaliculi
what is an osteocyte?
mature bone cell which sits within lacunae
what is the small space between lamellae which house osteocytes?
lacunae
What canals perforate though to the periosteum?
perforating canal
What is the structural unit of spongy bone made up of an irregular network of concentric lamellae?
Trabeculae
