Cocaine normally stays in the system for approximately 48 hours. Although the method of administration and the dose administered affects how long it takes for the body to metabolize this drug. When coca leaves are chewed, absorption time is around 30 minutes.
In this article, we shall look at the anatomy of the muscles of the upper arm â their attachments, innervation and actions. There are three muscles located in the anterior compartment of the upper arm â biceps brachii, coracobrachialis and brachialis. They are all innervated by the musculocutaneous nerve. A good memory aid for this is BBC â biceps, brachialis, coracobrachialis.
The Adductors are a group of muscles that include: the Adductor Magnus, Longus and Brevis, the Gracilis and the Pectineus. The Adductor Hiatus (not pictured) is simply a space in the attachment of the Adductor Magnus. The Adductors originate on the pelvic bone and attach at intervals along the length of the femur. This interval attachment provides the most power and stability for the hip joint and the femur. The Sartorius muscle is also included in this diagram though it's not technically an adductor-it acts at the hip to internally rotate the femur (a movement like you're crossing one leg over the other).
