Study Notes
Cartilage
- Elastic cartilage is commonly found in the external ear and epiglottis.
- The main function of elastic cartilage is to provide flexibility and maintain shape.
- Hyaline cartilage is the strongest type and does not have perichondrium.
- Fibrocartilage can be commonly found in intervertebral discs, pubic symphysis, and the temporomandibular joint.
- The distinguishing feature of fibrocartilage microscopically is the presence of dense bundles of collagen fibers.
Blood and Lymph
- The main function of blood is to transport oxygen and nutrients to cells and remove waste products.
- White blood cells (leukocytes) fight infections.
- The function of lymph in the body is to defend against disease and maintain tissue fluid balance.
- The liquid left after clotting proteins are removed from blood is called serum.
- Platelets help to form blood clots and stop bleeding.
Connective Tissue
- Loose connective tissue has very few protein fibers and becomes visible during clotting.
- The main function of dense regular connective tissue in tendons and ligaments is to provide tensile strength.
- The Achilles tendon is the structure most likely to be affected by Achilles tendonitis.
- Tendonitis in connective tissues is caused by inflammation or injury.
- If a ligament is torn, it can cause joint instability.
- The arrangement of collagen fibers in ligaments and tendons is parallel.
- The fluid-filled protective sheaths covering tendons are called synovial tendon sheaths.
- The extracellular matrix in connective tissue is primarily made of interstitial fluid, cell adhesion proteins, and proteoglycans.
Tissue Types
- Mesenchyme is the embryonic tissue from which all connective tissues arise.
- Loose connective tissue has a good blood supply and many nerves, except for some exceptions like cartilage and tendons.
- The main function of connective tissue related to 'binding and support' is to provide a framework for the body.
- Collagen fibers in the extracellular matrix of connective tissue determine tissue strength and rate of diffusion.
Glands
- Apocrine glands secrete products by shedding whole cells.
- Holocrine glands involve cells bursting to release cytoplasmic contents.
- Merocrine glands involve exocytosis for secretion.
- Tissue that is the most abundant and widely distributed is connective tissue.
General
- In connective tissue, the type and arrangement of fibers and the type of cells determine the role of the tissue.
- Apocrine glands involve pinching off a portion of the cell to release its secretion.
