ANT334H5 Lecture Notes - Lecture 2: Loose Connective Tissue, Osteoid, Biomineralization
Document Summary
Consists of dense fibrous tissue and cellular layer. Fibres of ligaments and tendons blend with and pass through periosteum before anchoring to bone tissue below. Consists of loose connective tissue and cellular layer. Mensenchymal cells (stem cells; which differentiate into every other type of cell) which can differentiate into. Osteoprogenitor cells produce bone or produce into. Initiate mineralization by releasing calcium but if there are some problem with spaces (not enough vitamin d), this will not mineralized) Becomes embedded within the osteoid it continues its life as an osteocyte. Need supplies to be delivered to them to do their jobs, and therefore connected via canaliculi. Transportation and communication network throghout bone matrix. Ostetocytes maintain bone matrix quality in which they are embedded in. Work in combination with osteoblast (osteocyte-osteoblast pump) and together they maintain blood calcium levels. Cells that remove bone (lava monster of the body) Produced quickly which is why is it unorganized.
