what muscles are in the front of your arm
The shoulder forms a base for the arm with most of the upper arm muscles originating from this area. In the upper arm, the biceps and triceps are arranged to give the forearm power to thrust and bend. The two muscles join at the elbow and allow you to bend and straighten your arm and also rotate your wrist and hand.The forearm muscles transmit power to the wrist, hands, and fingers.he biceps brachii (two-headed arm muscle) consists of the long head and the short head. It extends from the shoulder to the elbow and is the main flexor of the elbow joint. When working with other nearby muscles, it can also move the shoulder, since its upper ends are attached to the scapula (shoulder blade).
