Study Notes
Cartilage
- Pubic symphysis is formed by hyaline cartilage.
- Epiphyseal plate is formed by hyaline cartilage.
- Articular cartilage of joints is formed by hyaline cartilage.
Collagen
- Type II collagen is found in cartilage.
- Type III collagen is not found in cartilage.
- Type VI collagen is not found in cartilage.
- Type I collagen is found in bone tissue.
Connective Tissue
- Macrophages are cells derived from monocytes, specialized in protein fiber turnover and removal of apoptotic cells, tissue debris, or other particulate material.
- Loose connective tissue is located beneath the epithelial lining of many organs and fills the spaces between fibers of muscle and nerve.
- Dense irregular connective tissue is found in skin, fascia, and tendon sheaths.
- Reticular fibers are present in the stroma of hemopoietic tissue (bone marrow), the spleen, and lymph nodes.
Blood Cells
- Plasma cells are lymphocyte-derived, antibody-producing cells.
- Basophils are granulocytes with surface receptors for immunoglobulin E (IgE).
- Eosinophils are granulocytes with large, blue granules that often obscure the nucleus.
- Monocytes mature into macrophages.
- Neutrophils are the most abundant in a peripheral smear of blood.
Blood Components
- Pus is a substance consisting of apoptotic neutrophils, bacteria, semidigested material, and tissue fluid.
- Histamine increases vascular wall permeability, leading to edema.
- Platelet-activating factor increases vascular wall permeability, leading to edema.
- Hematocrit is the volume of packed RBCs in a sample of blood.
Blood Functions
- Albumin maintains osmotic pressure.
- Eosinophils release enzyme histaminase to decrease the amount of histamine during allergic reactions.
- The approximate lifespan of circulating erythrocytes is 4 months.
Other
- Chondronectin is a glycoprotein of cartilage tissue.
- Osteonectin is a glycoprotein of bone tissue.
- Fibronectin is a glycoprotein of loose connective tissue.
- Aggrecan is a glycoprotein of cartilage tissue.
- Lymphocytes are associated with antibody production.
- The function of hematocrit is to measure the volume of packed RBCs in a sample of blood.
