A sperm is the male reproductive cell. When the sperm has the usual single flagellum (or "tail") to propel it along, it is called a spermatozoon and may be described as uniflagellate. Unlike this motile cell, a sperm that lacks a flagellum is not motile and is termed a spermatium.

Drugs Targeting the 5-HT System

Serotonin or 5-hydroxytryptamine (5-HT) is a neurotransmitter that binds to 5-HT receptors in the central and peripheral nervous systems. Serotonin is an example of an inhibitory neurotransmitter that has general sedative effects on the brain and counteracts the effects of stimulants such as caffeine, for example.

What is Serotonin?

Serotonin is an example of a neurotransmitter, a chemical messenger that is passed between nerve cells. When a nerve impulse reaches the axon at the end of a nerve, neurotransmitters are released which cross an area called the synapse to be received by a specific receptor on the end of a target nerve. Once received by the target nerve, the neurotransmitter may either excite that nerve to fire its own signal or prevent it from firing the signal.

Tuberculosis Prognosis

Tuberculosis is a curable disease. Progress of tuberculosis from infection to frank illness involves overcoming of the immune system defences by the bacteria. As the bacteria start to multiply, it affects the immune system and finally overwhelms it to cause the disease.

Tuberculosis Treatment

Tuberculosis is a treatable and curable infection. Treatment for tuberculosis depends on the type of tuberculosis and a long course of antibiotics are prescribed. In most cases admission to the hospital is not necessary. As earlier believed, isolation also is not practiced widely these days.

Tuberculosis Screening

Screening for tuberculosis mainly involves screening for the presence of tuberculosis and the presence of latent tuberculosis.

Tuberculosis Prevention

Tuberculosis is a preventable and a curable disease if detected and treated early. It has a low prevalence in developed nations including the United Kingdom and the United States.

Tuberculosis Diagnosis

There are several investigations that may be used to diagnose tuberculosis. This may depend on the type of tuberculosis that is suspected.

Tuberculosis Transmission

Tuberculosis (TB) is transmitted from an infected person to a susceptible person in airborne particles, called droplet nuclei. These are 1–5 microns in diameter. These infectious droplet nuclei are tiny water droplets with the bacteria that are released when persons who have pulmonary or laryngeal tuberculosis cough, sneeze, laugh, shout etc.

Tuberculosis Causes

Tuberculosis is an infectious disease and is caused by a type of bacterium called Mycobacterium tuberculosis. One-third of the world's population is infected with the bacterium that causes tuberculosis. Each year about nine million people develop the disease and up to nearly two million people worldwide are killed by it.
