Study Notes
General Characters of Epithelium
- Can be ectodermal, endodermal, or mesodermal in origin
- Formed mainly of cells with few intercellular substances
- Cells rest on basement membrane
- Avascular (no blood, no lymphatic penetration)
- Highly innervated
- Has high power of regeneration
Types of Epithelium
- Surface Epithelium
- Simple Epithelium
- Stratified Epithelium
- Glandular Epithelium
- Neuro-Epithelium
- Myo-Epithelium
Types of Simple Epithelium
- Simple Squamous Epithelium
- Formed of single layer of flat cells with flat nucleus
- Site: lining blood vascular system, serous cavities, lung alveoli, Bowman's capsule, and loop of Henle in kidney
- Function: facilitates flow of fluids, easy movement, gas exchange, filtration, and diffusion
- Simple Cubical Epithelium
- Formed of single layer of cube-like cells with central rounded nucleus
- Site: secretory units, convoluted tubule of kidney, and covering eye lens
- Function: responsible for secretion or reabsorption
- Simple Columnar Epithelium
- Formed of single layer of tall columnar cells with basal oval nuclei
- Site: stomach, intestine, cervical canal of uterus, and convoluted tubule of kidney
- Function: secretion or absorption
- Simple Columnar Ciliated Epithelium
- Formed of single layer of columnar cells with basal oval nuclei and cilia on surface
- Function: helps in secretion or absorption, with additional function of movement of substances due to cilia
Stratified Epithelium
- Stratified Cuboidal Epithelium
- Site: ducts of sweat glands
- Transitional Epithelium
- Site: lines urinary system (ureter and urinary bladder)
- Can change shape according to state of organ
Glandular Epithelium
- Epithelial cells modified for secretion
- Classified by:
- Presence or absence of ducts (exocrine, endocrine, or mixed glands)
- Number of cells (unicellular or multicellular)
- Mode of secretion (merocrine, apocrine, or holocrine)
Neuro-Epithelium
- Specialized epithelial tissue for receiving stimuli
- Consists of hair cells, supporting cells, and basal cells
- Site: taste buds, olfactory epithelium, and organ of Corti
Myo-Epithelium
- Specialized epithelial tissue with contractile cells
- Site: around secretory cells in exocrine glands
- Function: helps secretory cells to squeeze and evacuate secretion
