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.
Arm Abduction. Abduction of the arm is also called abduction of/at the shoulder. This motion actually can be divided into two motions: true abduction of the arm at the shoulder and upward rotation of the scapula. Muscles: supraspinatus (initiates abduction - first 15 degrees), deltoid (up to 90 degrees), trapezius and serratus anterior (scapular rotation, for abduction beyond 90 degrees).
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).
