Human olfactory system. Computer artwork showing the olfactory bulb (top) full of olfactory neurons (nerve cells), and an olfactory receptor cell (yellow, vertical). The olfactory bulb is situated in the forebrain (prosencephalon). It has many olfactory receptor cells that project into the epithelial lining (pink) of the nasal cavity. The receptors (bottom, long, thin) embedded in the membrane of the receptor cells pick up smell information from molecules inhaled through the nose. This information is transmitted to the olfactory bulb and sent as a nerve impulse to the brain.

Lactobacillus sp. bacteria, colored scanning electron micrograph (SEM). Lactobacillus bacteria are probiotic bacteria, which are useful for human and animal health as they produce bacteriocins (toxins that kill off competitive bacteria), which prevents infection by pathogenic bacterial strains. They are usually added to probacterial foods such as yogurts and health bars. Magnification: x12,350 when printed 10 centimeters wide.

One Shot Tops Acupuncture Pain Relief

In the news:

The transmission of pain. 
Pain messages are transmitted through a peptide transmitter known as Substance P (yellow spheres) to spinal neurone cells in the spinal cord. At center left a spinal neurone has been opened to show the relation between the Substance P and its receptor sites (yellow c-shaped). At bottom right a spinal interneurone is just visible with a short axon terminating on an axon of the spinal neurone. Here receptor sites (red c-shaped) of opiopeptins (red spheres) are found. Opiopeptins are contained in analgesic drugs and may alleviate pain because they inhibit the release of the Substance P.
