What organelles are in an osteocyte?
Osteocytes, also known as bone cells, have all the organelles found in other eukaryotic cells, such as a nucleus, mitochondria, cell membrane and endoplasmic reticulum. They have only one nucleus.
What is the structure of osteocytes?
osteocyte, a cell that lies within the substance of fully formed bone. It occupies a small chamber called a lacuna, which is contained in the calcified matrix of bone. Osteocytes derive from osteoblasts, or bone-forming cells, and are essentially osteoblasts surrounded by the products they secreted.
What is osteocytes in biology?
Osteocytes are defined as cells embedded within the bone matrix. As the osteocyte is the longest-lived bone cell, it should be considered a memory cell that can undergo senescence with aging.
Do osteocytes have a Golgi apparatus?
The cell also exhibits a reduced size endoplasmic reticulum, Golgi apparatus and mitochondria, and cell processes that radiate largely towards the bone surfaces in circumferential lamellae, or towards a haversian canal and outer cement line typical of osteons in concentric lamellar bone.
What are osteogenic cells?
Osteoprogenitor cells, also known as osteogenic cells, are stem cells located in the bone that play a prodigal role in bone repair and growth. These cells are the precursors to the more specialized bone cells (osteocytes and osteoblasts) and reside in the bone marrow.
What is the function of osteocyte?
The potential functions of osteocytes include: to respond to mechanical strain and to send signals of bone formation or bone resorption to the bone surface, to modify their microenvironment, and to regulate both local and systemic mineral homeostasis.
What is the function of the osteocytes?
Which statement characterize central canals of Osteons?
it contains a central canal. it is also called a Haversian system. which statements characterize central canals of osteons? they contain osteocytes.
What do osteocytes cells do?
How osteocytes get nutrients?
Osteocytes receive nutrients and eliminate wastes through blood vessels in the compact bone. Blood vessels in the periosteum and endosteum supply blood to blood vessels in the central canals. Nutrients leave the blood vessels of the central canals and diffuse to the osteocytes through the canaliculi.
Do osteocytes have lysosomes?
Under the electron microscope, there were a few lysosomes, mitochondria, and rough endoplasmic reticulum in the cytoplasm, and the Golgi complex was also underdeveloped. Therefore, osteocytes form an extensive connecting syncytium network via small cytoplasmic/dendritic processes in canaliculi.
