Study Notes
Cartilage and Bone
- Blood vessels are absent in cartilage matrix but present in bone, indicating a major difference in vascularization.
- Fibrous cartilage is involved in herniated discs between vertebrae, providing shock absorption and tensile strength.
- Hyaline cartilage differs from elastic and fibrocartilage in that its fibers are not normally visible.
Types of Fibers and Tissues
- Connective tissues contain three primary fiber types: collagen, reticular, and elastic.
- Simple columnar epithelium plays a role in digestion and is adapted for absorption or secretion with microvilli on the surface.
- Epithelial tissue is avascular (no blood vessels) but is innervated (contains nerve endings).
Epithelial and Connective Tissue
- Epithelial tissue always has a free surface exposed to an environment; it is categorized based on structure, such as simple and stratified.
- Stratified squamous epithelium has multilayered flat cells, while simple cuboidal epithelium features a single layer of cube-shaped cells.
- Goblet cells are wedged between simple columnar epithelial cells, indicating their role in secretion.
Glandular Epithelia
- Compound alveolar describes mammary glands, while compound tubuloalveolar represents salivary glands, both illustrating different exocrine gland structures.
- Endocrine glands, like the thyroid, secrete hormones directly into the bloodstream without ducts.
Muscle and Connective Tissue
- Skeletal muscle cells are multinucleated and primarily enable voluntary movements, while cardiac muscle tissue is branched and interconnected.
- Areolar connective tissue makes up the framework of mucous membranes, providing structural support.
Healing and Regeneration
- Bone injuries typically heal faster than cartilage injuries due to better blood supply in bones, which also continuously remodels tissue.
- Antiangiogenesis factor is a chemical produced by cartilage cells that inhibits blood vessel growth.
Intercellular Connections and Matrix
- Tight junctions refer to intercellular connections resulting from the partial fusion of lipid membranes for barrier functions.
- The extracellular matrix comprises fibers and ground substance, essential for structural integrity and function across various tissues.
