Tissue - definition of tissue by Medical dictionary
This term is especially used in relation to muscles, tendons, ligaments, skin, fat, and other connective tissues that are occasionally the source of pain when they are injured. brown adipose tissue a thermogenic type of adipose tissue containing a dark pigment, and arising during embryonic life in certain specific areas in many mammals, including humans; it is prominent in the newborn
Although cartilage cells are not abundant, they are arranged in scattered clusters in parallel arrays, reflecting the direction of stresses placed upon the tissue. The cells that produce cartilage are called chondroblasts, and, in mature cartilage where the cells are housed in lacunae, they are termed chondrocytes
Cells of the Connective Tissue Proper Although the connective tissue has a lower density of cells than the other tissues you will study this year, the cells of these tissues are extremely important. How would you distinguish a fibroblast, macrophage, and mast cell under the light microscope? Answer: Fibroblast may be very basophilic because it has a lot of RER, and you may actually be able to see it releasing collagen
Connective tissue - definition of connective tissue by Medical dictionary
The supporting or framework tissue of the body, arising chiefly from the embryonic mesoderm and including collagenous, elastic and reticular fibers, adipose tissue, cartilage, and bone.

All of the above are fibers found in connective tissue Answer: d There are three types of fibers found in connective tissue: collagen fibers, elastic fibers, and reticular fibers
Connective Tissues - Jim Campbell
Back to top of page Hyaline Cartilage Connective Tissue (100X) This tissue has a matrix that is firm enough to bear a lot of pressure without permanent distortion. Back to top of page Osseous Connective Tissue (Bone - 100X) The slide you will be looking at is a slice of dense bone from the shaft of a long bone that hase been ground down to become extremely thin and translucent (hence the slide name, "ground bone")
Connective Tissue
101 of Ross et al.) In routine histological preparations, only the nucleus of the fibroblast can be identified, the cytoplasmic processes blend in with the surrounding collagen. A family of seven distinct GAGs is recognized, based on differences in the specific sugar residues, the nature of the linkages and the degree of sulfation
THE CONNECTIVE TISSUES
Tissues and organs subject to expansive forces contain elastic fibers, such as, the walls of arteries, the vocal cords, skin, the trachea and the bronchi. The tough, inelastic tendonous sheets and cords formed by tendons provide great resistence to pulling forces, e.g., a pencil thick tendon has been found to support up to 1000 pounds
CONNECTIVE TISSUE
Their main function is to plug (patch) small breaks in blood vessels and prevent bleeding (hemorrhage); they adhere to connective tissue exposed at the damaged site and initiate clot formation. Acute inflammatory responses in loose connective tissue are characterized by changes in blood vessel permeability, migration of cells involved in clearing debris as well as by healing or walling off the damaged area
Classification CONNECTIVE TISSUE PROPER (examples of these are shown below) loose irregular connective tissue dense irregular connective tissue SPECIALISED CONNECTIVE TISSUES dense regular connective tissue which is found in tendons and ligaments, and is shown below. Cells are the predominant feature in tissues specialised for protection (haemopoietic tissue, blood - white blood cells) or metabolic maintenance (adipocytes, blood - red blood cells)
Blue Histology - Connective Tissues
For example, in the palms of the hands, on the plantar surface (sole) of the feet and in the gluteal region (buttocks) it has a structural, cushioning function. Elastic fibres Elastic fibres are coloured in fresh tissues - they are light yellow - but this colouration is only visible if large amounts of elastic fibres are present in the tissue, for example, in the elastic ligaments of the vertebral column
What Is Dense Irregular Connective Tissue? (with pictures)
Connective tissue provides support to the organs and tissues of the body and is separated into two types: loose connective tissue, which is more abundant, and dense connective tissue. The human body is so well designed and well thought out! Every little cell has a purpose, and the fact that we have cushions in the form of tissue surrounding all our important organs is astounding to me
SIU SOM Histology INTRO
The major determinant of the mechanical properties of most connective tissue is the extracellular matrix which is secreted by the cells within it (fibroblasts in ordinary connective tissue, osteoblasts and chondroblasts in bone and cartilage respectively). Collagen is secreted by fibroblasts as procollagen molecules, converted extracellularly into tropocollagen which self-assembles into microscopically visible fibers and grossly evident mechanical structures such as tendons
