Histology notes

The cells are flattened and their internal organelles exhibit the characteristics of cells that have reduced synthetic activity.

Sections can be cut through the tissue in a number of directions. Dominant component of extracellular matrix is collagen fibers.

These are in addition to the cavities already formed in spongy bone. Since the decision is to treat or not to treat, we believe that ovarian carcinomas should be classified either into either low Histology notes or high grade, with chemotherapy withheld for low grade stage I cases.

Mesenchymal cells aggregate and begin to secrete matrix that is characterized by bundles of collagenous fibers.

Dogs do not seem to use this form of communication with one another and only look for visual Histology notes from the eyes of humans. As this calcification takes place, the mesenchymal cells undergo morphological changes. The osteoid matrix becomes mineralized forming cancellous bone in the shaft of the diaphysis.

Actual osteogenesis bone ossification begins with the establishment of a periosteum on the shaft or diaphysis of the cartilage template and the laying down of an intramembranous collar of bone on the circumference of the cartilage diaphysis.

If pressure is applied slowly, the eye is actually very elastic. Sufficiently small objects which become embedded and which are subsequently left untreated may eventually become surrounded by a benign cystcausing no other damage or discomfort. May be more than one cell in a lacuna.

On the Word

What we have just discussed is endochondral bone formation. These passageways provide a means through which blood vessels, nerves and undifferentiated mesenchymes cells can enter into the lacunae spaces in the remnants of the cartilage matrix that have been left by the degenerating chondrocytes.

Actual osteogenesis bone ossification begins with the establishment of a periosteum on the shaft or diaphysis of the cartilage template and the laying down of an intramembranous collar of bone on the circumference of the cartilage diaphysis.

The reabsorption and redeposition of compact and spongy bone continues throughout life. Most easily seen in articular disks such as the intervertebral disks.

These cells reside in small spaces within the matrix that are called lacunae. Inner layer next to cartilage matrix contains cells that are thought by some to be fibroblasts and by others to be undifferentiated mesenchyme cells. The end result is a cartilage template of the bone in miniature that contains chondrocytes embedded within the cartilage matrix.

Secrete extracellular matrix, but are not yet rigidly embedded in that matrix. As bone is being formed, there is also localized removal of the bone matrix by another set of connective tissue cells known as osteoclasts.

It contains embedded osteocytes that are in communication via gap junctions at their contacting cytoplasmic processes. These cells either aggregate where bones are to form intramembranous bone formation and lay down the matrix that will later become calcified, or they migrate into pre-existing cartilage "models " of the presumptive bone and replace the cartilage with a calcareous matrix endochondral bone formation.

This takes place as discussed above via the action of chondroblasts that have migrated to the area.

In areas where these Histology notes occur, they are located on the surfaces of forming bone and are not yet embedded in the extracellular matrix. These passageways provide a means through which blood vessels, nerves and undifferentiated mesenchymes cells can enter into the lacunae spaces in the remnants of the cartilage matrix that have been left by the degenerating chondrocytes.

Individual lab sections begin with a short list of Suitable Slides and stains. Each page begins with a table of contents which lists the topics, lab guides and images contained in the page. As this occurs, the chondrocytes loose their ability to maintain the remaining cartilage matrix and it becomes partially calcified.
