In this essay, I am going to write about the social and historical context of 'Of Mice and Men', and how the dreams of certain people in the ranch went wrong and ended in tragedy. Most of the characters in 'Of Mice and Men' admit, at one point or another, to dreaming of a different life.
The origins of both the triceps and the biceps are at the top of the humerus near the shoulder joint. As the bicep contracts, the lower arm (radius and ulna) moves up towards the shoulder. The triceps relax to allow this movement to happen. The bicep is the prime mover or agonist, while the tricep is the secondary mover or antagonist. Muscles are attached to bones at either side of the joints by tendons.
Although it may seem simple, stretching your arms over your head requires a complex, coordinated movement of your whole shoulder girdle, termed the scapulohumeral rhythm. Many muscles are involved in this action, including the rotator cuff muscles on your shoulder blade, the deltoid muscle on your outer shoulder and the trapezius and serratus anterior muscles on the back and side of your ribcage.
