Spider monkeys are found in many aspects of the Mesoamerican cultures. In the Aztec 260-day calendar, Spider Monkey (Nahua Ozomatli) serves as the name for the 11th day. In the corresponding Maya calendar, Howler Monkey (Batz) is substituted for Spider Monkey.
A migraine is a throbbing painful headache, usually on one side of the head, that is often initiated or triggered by specific compounds or situations (environment, stress, hormones, and many others). They occur more often in women (75%, approximately) and may affect a person's ability to do common tasks.
The new drugs are not a pill, but injections of laboratory-made molecules called monoclonal antibodies. They block the function of a small protein that widens blood vessels and helps transmit pain signals throughout the body. This protein, called CGRP, has been known to play a role in migraines for more than 20 years.
