Furthermore, areolar tissue is the same as loose connective tissue, adipose tissue is a subset of specialized connective tissue, and reticular tissue is the presence of reticular fibers and reticular cells together forming the stroma of hemopoietic tissue (specifically the red bone marrow) and lymphatic tissue organs (lymph nodes and spleen but ...
Connective tissue is one of the four primary types of animal tissue, a group of cells that are similar in structure, along with epithelial tissue, muscle tissue, and nervous tissue. [1] It develops mostly from the mesenchyme , derived from the mesoderm , the middle embryonic germ layer . [ 2 ]
The connective tissue of the lamina propria is loose and rich in cells. The cells of the lamina propria are variable and can include fibroblasts, lymphocytes, plasma cells, macrophages, eosinophilic leukocytes, and mast cells. [2] It provides support and nutrition to the epithelium, as well as the means to bind to the underlying tissue.
Adipose tissue (also known as body fat or simply fat) is a loose connective tissue composed mostly of adipocytes. [ 1 ] [ 2 ] It also contains the stromal vascular fraction ( SVF ) of cells including preadipocytes , fibroblasts , vascular endothelial cells and a variety of immune cells such as adipose tissue macrophages .
The lamina propria, a layer of connective tissue within the mucosa. The muscularis mucosae, a thin layer of smooth muscle. The epithelium, the most exposed part of the mucosa, is a glandular epithelium with many goblet cells. Goblet cells secrete mucus, which lubricates the passage of food along and protects the intestinal wall from digestive ...
The subcutaneous tissue is derived from the mesoderm, but unlike the dermis, it is not derived from the mesoderm's dermatome region. It consists primarily of loose connective tissue and contains larger blood vessels and nerves than those found in the dermis. It is a major site of fat storage in the body.
Loose connective tissue contains fibers, extracellular matrix, cells, nerves and blood vessels. The extracellular compartment consists of Type 1, 3, and 5 collagen fibers bundles embedded in intercellular substance. The PDL collagen fibers are categorized according to their orientation and location along the tooth.
The fibrous pericardium is the outside layer of the pericardium, made up of dense and loose connective tissue. [5] While capable of some change in shape, it is largely non-pliable, which acts to protect the heart against blunt forces and sudden pressure change from the outside.
