EXERCISE 10 CONNECTIVE TISSUE Flashcards
This tissue is distributed throughout the body but is never exposed to the outside environment
CONNECTIVE TISSUE
Three basic components of Connective Tissue
Specialized Cells
Fibers
Ground substance
It fibers and ground substance from the matrix that surrounds the cells
CONNECTIVE TISSUE
Areolar or Loose Connective Tissue
COLLAGEN FIBER - numerous and the largest. This fiber is thick and somewhat wavy and exhibit faint longitudinal striations. They are present in varying abundance in all types of connective tissue. It is flexible but offer great resistance to a pulling force and abundant in the dermis, bone, tendon, dentin etc.
ELASTIC FIBER - is fine, single fiber, which is usually straight and form branching and anastomosing network. This fiber has the ability to be stretched by a small force and return to its original dimension when the force is removed. The aorta and lungs are rich in elastic fibers
RETICULAR FIBER - is very slender fiber which tends to form delicate network rather than coarse bundles. This fiber persist in delicate networks surrounding adpose cells, smooth muscle cells, sarcolemma of striated muscle, endoneurium of nerve cells and in close association with the basal lamina of most epithelia.
CELLS - a fibroblast is one of the fixed cells of a loose connective tissue. The cell is flattened with oval nucleus. Inactive macrophage appear like fibroblast but nucleus is smaller. Most cells are ovoid with small pale centrally placedd nuclei. Blood lymphocytee and eosinophil.
Tissue is found where great tensile strength is required, such as in ligament and tendon
Dense Regular Connective Tissue
In this tissue the collagenous fibers are larger, more numerous, and more concentrated. Elastic fibers are also larger and more numerous
Dense Irregular Connective Tissue
is a specialized form of connective tissue characterized to have no nerves or blood vessels of its own
Cartilage
Has the perichondrium, matrix, lacuna, and chondrocyte
Hyaline Cartilage
It has the presence of elastic fiber in the matrix. The fiber enter in the cartilaginous matrix from the perichondrium.
Elastic Cartilage
The matrix is permeated with collagenous fibers. Small chondrocytes in lacunae are usually distributed in rows within the fibrous matrix. Perichondrium is absent because fibrous cartilage forms a transition area between hyaline and tendon or ligament
Fibro Cartilage
It has the periosteum, periosteal lamella, and haversian systems
Haversian Canal
Concentric Lamella
Lacunae
Canaliculi
Osteocyte
Bone or Osseous Tissue
This tissue fills up spacesbetween organs. It can be seen in subcutaneous layer of the skin and other parts.
Adipose or Fat Tissue
