This session will introduce the general structure and function of the biological macromolecules: lipids, carbohydrates, and nucleic acids. Learning Objectives. 1  To understand the general structure and properties of lipids and phospholipids and their function in the cell.
Postherpetic neuralgia is a nerve pain due to damage caused by the varicella zoster virus. Typically, the neuralgia is confined to a dermatomic area of the skin, and follows an outbreak of herpes zoster (commonly known as shingles) in that same dermatomic area.
The cause of postherpetic neuralgia is shingles, an infection caused by the chickenpox virus. The likelihood of having this infection increases with age. Lyme disease, HIV, and syphilis can also cause neuralgia.he myelin on nerves can be worn away by pressure. The pressure may come from a bone, ligament, blood vessel, or a tumor that is pressing on the nerve. The pressure of a swollen blood vessel is a common cause in trigeminal neuralgia.
