What layers are just inside the periosteum?
The periosteum consists of an outer fibrous layer, and an inner cambium layer (or osteogenic layer). The fibrous layer is of dense irregular connective tissue, containing fibroblasts, while the cambium layer is highly cellular containing progenitor cells that develop into osteoblasts.
What is in the inner layer of the periosteum quizlet?
This connective tissue is made up of two different layers: The fibrous periosteum is the outer layer furthest away from the bone. The cells in this layers are densely packed, and it contains lymphatics, blood vessels and nerve endings. The osteogenic periosteum is the inner layer that lies right on top of the bone.
What is the inner layer of bones called?
Endosteum: A membrane lining the inner surface of the bony wall also identified as the lining membrane of the Bone marrow cavity is endosteum; The endosteum lines the Haversian canal and all the internal cavities of the bone.
What tissue is in the outer layer of the periosteum?
The outer layer of the periosteum is mostly made of elastic fibrous material, such as collagen. It also contains blood vessels and nerves. The blood vessels of the periosteum contribute to the blood supply of the body’s bones. They can pass into the dense and compact layer of bone tissue below, called the bone cortex.
What type of tissue makes up the periosteum?
The periosteum consists of an outer “fibrous layer” and inner “cambium layer”. The fibrous layer contains fibroblasts while the cambium layer contains progenitor cells which develop into osteoblasts that are responsible for increasing bone width.
What is the periosteum composed of?
What tissue type is in the outer layer of the periosteum?
dense fibrous membrane
periosteum, dense fibrous membrane covering the surfaces of bones, consisting of an outer fibrous layer and an inner cellular layer (cambium). The outer layer is composed mostly of collagen and contains nerve fibres that cause pain when the tissue is damaged.
What type of connective tissue is periosteum?
The periosteum is a dense, fibrous connective tissue sheath that covers the bones. The outer layer, made up of collagen fibers oriented parallel to the bone, contains arteries, veins, lymphatics, and sensory nerves.
