former osteoblasts that have become surrounded in bone matrix that is calcified
The space between cells can be called the extracellular space, the extracellular material, or the extracellular matrix. This space is not a vacuum; it is filled with material. If the material is gel-like it is called the ground substance, which is filled with many dissolved solute particles, and the tissue will be loose. If the material in the extracellular space has some fibers of protein in it, the entire tissue will have a stronger consistency.
Extracellular material is found outside of the cell.
The cell membrane, also known as the plasma membrane, separates the intracellular material from the extracellular material. This selectively permeable barrier controls the passage of substances in and out of the cell, helping to maintain cellular homeostasis.
Calcified opacity is a radiological word that means there was an opaque area in rays that could not penetrate and just appear like a bone. This also means that the light does not pass though the material being described.
The process you are describing is endocytosis. During endocytosis, the cell membrane envelops extracellular material forming a vesicle, which is then brought into the cell. This mechanism allows the cell to uptake nutrients or internalize signaling molecules.
Connective tissue is the class of tissue comprised of widely spaced cells and abundant extracellular material. This extracellular material can include fibers and ground substance that provide support and structure to the tissue. Examples of connective tissue include bone, cartilage, and adipose tissue.
Yes, interstitial fluid is a type of extracellular material. It surrounds cells in tissues and is composed of water, electrolytes, and various solutes that are essential for maintaining cellular functions.
Extracellular components include cellulose, teeth, bone cartilage, and connective tissue. To sum it up, extracellular components are material outside the cell membrane.
Receptor-mediated endocytosis.It is the mechanism that allows cells to concentrate material that is present only in very small amounts into the extracellular fluid.
You are looking for the term extracellular matrix.
Yes, connective tissue contains extracellular matrix, which is a non-living material that provides structural support and connects cells within the tissue.
The main extracellular material in connective tissue for resisting tension is collagen. Collagen fibers provide strength and support to connective tissues, such as tendons, ligaments, and the dermis of the skin.
