Study Notes
Epithelial Tissue
- Abundant extracellular material is not a feature of epithelia.
- Epithelial tissues are strong membranes that bind the body together.
- A single layer of tall cells is classified as simple columnar epithelium.
- Tight junctions create seals between cells, while gap junctions allow communication.
Connective Tissue
- Aerobic connective tissue is not a recognized category; the main categories include connective tissue proper, supporting connective tissue, and fluid connective tissue.
- Adipose tissue is classified as loose connective tissue, not dense.
- Elastic connective tissue is found in artery walls and airways.
- Chondrocytes and osteocytes are located in lacunae.
Muscle Tissue
- Smooth muscle is present in the walls of hollow organs.
- Genetic inheritance affecting gap junctions can lead to abnormal cardiac and smooth muscle function, while skeletal muscle remains unaffected.
- There are three types of muscle tissue: skeletal, cardiac, and smooth.
Nervous Tissue
- Nervous tissue consists of specialized cells that monitor environments and initiate bodily responses.
- It comprises neurons and glial cells, which support neural activities.
Classification of Epithelial Tissue
- Epithelial tissue is classified by the number of cell layers and the shape of cells at the apical surface.
- Simple squamous epithelium is involved in diffusion, filtration, secretion, and protection based on location.
- Simple cuboidal epithelium functions in absorption, secretion, and protection.
- Stratified squamous epithelium provides protection for underlying layers.
- Pseudostratified columnar epithelium aids in moving secretions across the tissue surface.
- Transitional epithelium accommodates changes in organ volume through distension and relaxation.
