Study Notes
Epithelial Tissues
- The epithelial tissue responsible for protecting the skin is the epithelium.
- Elevation of sex hormones in epithelia leads to hypertrophy.
- Examples of merocrine glands include salivary glands, sweat glands, and pancreas.
- Epithelial tissues are characterized by:
- close packing of cells
- minimal intercellular substances
- cells that are attached to each other through cell junctions
- apical and basolateral surfaces
Connective Tissues
- The connective tissue characterized by a gelatinous matrix is mucous connective tissue.
- The primary function of connective tissues is to provide support, connect, and separate different organs and tissues.
Cartilage
- Chondrocytes in cartilage are responsible for producing and maintaining the cartilage matrix.
Zoology
- The main focus of Zoology is the study of animals and their evolution, structure, behavior, and classification.
- The main divisions of Zoology are:
- Embryology
- Comparative anatomy
- Morphology
- Ethology
- Ecology
- Systematics
- NOT one of the main divisions of Zoology mentioned in the text is Biotechnology.
Tissue Development
- The tissues originate from the three primary germ layers: ectoderm, endoderm, and mesoderm.
General Characteristics
- A general characteristic of epithelial tissues is that they are avascular, meaning they do not have blood vessels.
- The primary function of epithelial tissues is to form a barrier against the external environment and to regulate the exchange of substances between the external environment and the body.
