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.
