Study Notes
Tissues of the Body
- A tissue is a group of cells with similar morphological characteristics, specialized to perform specific functions.
- There are 4 basic tissues in the body: epithelial, connective, muscular, and nervous tissue.
Epithelial Tissue
- Epithelial tissue forms continuous sheets of cells that line internal cavities and cover the external surfaces of the body.
- General characteristics of epithelial tissue:
- Cells are tightly joined together.
- Cell boundaries are ill-defined.
- Cells rest on a basement membrane.
- Originate from the three germ layers: ectoderm, mesoderm, and endoderm.
- Avascular but highly innervated.
- Cells can regenerate.
- Can modify to form other types (glandular epithelium, neuro-epithelium, and myo-epithelium).
Classification of Epithelial Tissue
- Surface Epithelium: covers surfaces of the body or lines luminal cavities within the body.
- Types of epithelial tissue:
- Simple epithelium: one layer of cells.
- Stratified epithelium: more than one layer of cells.
- Squamous epithelium: flat, plate-like cells.
- Squamous keratinized epithelium: found in skin.
- Transitional epithelium: found in urinary tract.
- Glandular epithelium: forms glands.
- Neuro-epithelium: forms sensory receptors.
- Myo-epithelium: found in exocrine glands.
- Columnar epithelium: tall, column-like cells.
- Cuboidal epithelium: cube-like cells.
- Pseudo-stratified columnar epithelium: appears multi-layered but is not.
- Ciliated epithelium: has hair-like structures.
- Pseudo-stratified columnar epithelium with goblet cells: found in respiratory tract.
- Respiratory epithelium: lines the upper respiratory tract (nasal cavity, trachea, and bronchi).
- Simple squamous epithelium: lines blood vessels.
- Simple columnar epithelium: lines the digestive tract.
- Simple cuboidal epithelium: lines the kidneys and adrenal glands.
- Pseudostratified columnar epithelium: lines the respiratory tract.
