Study Notes
Basic Types of Body Tissue
- Four primary types of tissues: Epithelial, Connective, Nervous, and Muscle.
- Epithelial tissue serves as protective covering and can be found in skin and linings of organs like the intestine.
- Connective tissue supports and binds other tissues, exemplified by adipose tissue.
- Nervous tissue transmits electric signals throughout the body, including neurons and glial cells.
- Muscle tissue is responsible for body movement.
Epithelial Tissue Functions
- Provides protection to underlying structures.
- Facilitates absorption of nutrients and water.
- Acts in filtration, particularly in kidneys, to regulate exchanges.
- Involved in secretion and excretion through glandular formations.
Special Characteristics of Epithelium
- Cellularity: Comprises tightly packed cells with minimal extracellular material.
- Specialized Contacts: Cells are interconnected via desmosomes and tight junctions, forming continuous sheets and preventing material leaks.
- Polarity: Contains an apical surface facing the body surface and a basal surface attached to connective tissue.
- Support by Connective Tissue: Epithelia are supported by underlying connective tissues, primarily collagen fibers in the reticular lamina.
- Innervated but Avascular: Tissue receives nourishment through diffusion from blood vessels in adjacent connective tissue.
- High Regeneration Capacity: Capable of rapid cell division for replacement of dead or damaged cells.
Shapes of Epithelial Cells
- Squamous Cells: Flattened shape, allowing excellent diffusion and filtration capabilities.
- Cuboidal Cells: Cube-shaped with roughly equal height and width, primarily responsible for secretion and absorption.
