Explain what is meant by epithelial tissue being avascular but innervated.

Blood vessels do not penetrate epithelial sheets, making it avascular. It is, however, penetrated by nerve endings, making it innervated. Signup and view all the answers

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.
