Vesicular
Vesicular refers to something that is related to or characterized by vesicles. In the context of biology and medicine, a vesicle is a small structure within a cell, consisting of fluid enclosed by a lipid bilayer. Vesicles form naturally during the processes of secretion, uptake and transport of materials within the cell. They can also be artificially prepared.
Structure and Function[edit | edit source]
Vesicles are composed of a lipid bilayer membrane, surrounding a core consisting of a variety of substances. They are a basic tool used by the cell for organizing cellular substances. Vesicles are involved in metabolism, transport, buoyancy control, enzyme storage, and as chemical reaction chambers.
Types of Vesicles[edit | edit source]
There are several types of vesicles, including:
- Vacuoles: They are vesicles which contain mostly water.
- Lysosomes: These are vesicles that contain digestive enzymes to break down waste materials and cellular debris.
- Transport Vesicles: They move molecules between locations inside the cell.
- Secretory Vesicles: These vesicles hold various secretory products that are released into the extracellular environment.
Vesicular Diseases[edit | edit source]
Vesicular diseases are diseases that cause blisters and vesicles on the skin or mucous membranes. Some examples of vesicular diseases include:
- Herpes Simplex: This is a viral disease caused by the herpes simplex virus.
- Chickenpox: This is a highly contagious disease caused by the varicella-zoster virus.
- Hand, Foot, and Mouth Disease: This is a common viral illness that usually affects infants and children younger than 5 years old.
