Final answer:
The resistance in the lever system for the deltoid muscle can vary depending on the specific movement being performed. The deltoid muscle is responsible for abducting the arm and flexing it at the shoulder joint.
Step-by-step explanation:
The resistance in the lever system for the deltoid muscle can vary depending on the specific movement being performed. The deltoid muscle is responsible for abducting the arm and flexing it at the shoulder joint. When only the anterior fascicle of the deltoid is stimulated, the arm will abduct and flex. The resistance encountered by the muscle will depend on the load being lifted or the force being exerted.
