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 hamstrings are the opposing muscles, or antagonists, to the quadriceps muscles located on the front, or ventral, side of the leg. When the quads contract to extend your knee, they pull your leg up and allow you to move it away from your body. In this way, they are the prime mover, or the agonist.
