Cocaine can be detected in the urine for 4-8 hours after a single snorted (nasal) dose, and up to 24 hours after a single ingested (oral) dose. A breakdown product of cocaine, benzoylecgonine can be detected in the urine for up to 60 hours after a single use, or up to 22 days after repeated use.
1. Agonist: The agonist in a movement is the muscle(s) that provides the major force to complete the movement. Because of this agonists are known as the âprime moversâ. In the bicep curl which produces flexion at the elbow, the biceps muscle is the agonist, as seen in the image below.
A antagonist muscle is the muscle that opposes the agonist. So using the same example, during a biceps curl, the triceps is the antagonist muscle. This muscle relaxes as the biceps contracts. A synergist muscle is one that stabilizes a joint around which movement is occurring and helps to create movement. So again with the curl example, the brachialis and brachioradialis are the synergists muscles. They assist the biceps muscle and stabilize the elbow. When dropping the weight back down during a biceps curl exercise, the triceps becomes the agonist muscle and the biceps becomes the antagonist.
