Can You Influence The Sex Of Your Baby Or Whether You Have A Boy Or A Girl. What determines the sex of your baby? When it's time to have a baby, some couples are intent on trying various methods â such as diet, sexual position and timing â to try to conceive a boy or girl.
The biceps tendons attach the biceps muscle to the shoulder. Your shoulder is a ball-and-socket joint made up of three bones: your upper arm bone (humerus), your shoulder blade (scapula), and your collarbone (clavicle). The head of your upper arm bone fits into a rounded socket in your shoulder blade.
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.
