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.
The agonist is the main muscle responsible for a specific movement. The antagonist opposes the movement of the agonist, and is responsible for the opposing joint movement. For example, the triceps straighten the elbow joint. The biceps, which is responsible for bending the elbow joint, is the antagonist to the triceps.
