The use of percutaneous autologous bone marrow transplantation in nonunion and avascular necrosis of bone
According to Wallden,71 intra-osseous injection of a therapeutic substance was first described by Josefson in 1934, who administered campolon by direct intrasternal puncture to treat pernicious anaemia. The osteoblasts are not numerous, have a low proliferative capacity and a short half-life of two to three months, which explains the difficulty in achieving bony union
A) interstitial growth of the epiphyseal plates B) the secretion of bone matrix into the medullary cavity C) differentiation of osteoclasts D) calcification of the matrixAnswer: A3636) Growth of bones is controlled by a symphony of hormones. Which of the following hypotheses may explain how mechanical forces communicate with cells responsible for bone remodeling? A) Increase in the synthesis of growth hormone directs the remodeling process
Breast Anatomy
Large pecs are the result of muscular development behind the breast (pectoralis major and pectoralis minor muscles), and should not be confused with breast development. Some nipples are exceptionally wide and some are exceptionally long, and some people attempt to modify their appearance by using various pieces of "jewelry" that stretches them or enlarges them

Within a given reticular Fiber, the Collagen fibrils that compose its core are covered by a Glycoprotein coat that resembles material of the Basement Membrane. A cell that can adopt many shapes, depending on its activity, the Fibroblast produces the two major classes of extracellular material found in connective tissue: fibers and Ground Substance
What is Fascia? (with pictures)
I had a partial knee replacement 5 months ago, and I have a great feeling of constriction around my knee, as if it's in a vise which restricts movement. My physical therapist has been doing some deep tissue massage because she thinks that perhaps the fascia is not lying smoothly and is sort of bunched up, which is causing the constriction
In fact the so-called annular ligament does not exist; it is an integrated part of the aponeurotic layer of connective tissue via which supinator muscle fibers insert to the lateral epicondyle. The patterns of distribution and orientation in such zones are understandable from the perspective of the architecture of the muscular tissue related to the connective tissue architecture

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 are the differences between collagen and reticular fibers? (See lecture notes.) Do all tissues associated with reticular fibers constitute a reticular connective tissue? C. CELLS OF THE CONNECTIVE TISSUE PROPER SOURCE OF CELLS CELL TYPES MOTI- LITY NUCLEUS CYTOPLASM FUNCTION Mesenchymal cell of the embryo or those persisting in the adult
Lab 2. Connective Tissue
What is the pink-staining material which is interspersed within the reticular framework? Note the variations in the architecture of reticular fibers which you will come to understand later on. You may not be able to discern the difference between chondrocytes and fibroblasts by nuclear shape, but if a lacuna surrounds the cell, it is a chondrocyte; if not, a fibroblast
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
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
Connective Tissue
The small blood vessels (capillaries) are the size of collagen fibers, but may be distinguished from the latter by the presence of thin nuclei (of endothelial cells) oriented parallel to the axis of the capillary. Reticular C.T., containing a 3-dimensional network of reticular fibers, make up the stroma of lymphatic and hemopoietic tissues such as lymph nodes, thymus, spleen and bone marrow
What is Connective Tissue? (with pictures)
Yes, massage is great, but if you combine massage, or, myofascial release together with therapeutic dosages of systemic enzymes you will get superior results. The "other" category includes bone, which makes up the majority of the skeleton in adult vertebrates; blood, which transports nutrients and hormones throughout the body; and lymphatic tissues, which help transport nutrients between the blood and other cells and produce immune cells
