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.
When your biceps muscle in your upper arm contracts, it pulls your lower arm in towards your shoulder. However, when it relaxes, your biceps cannot push your arm back out. To do this, your triceps muscle, on the underside of your upper arm, contracts and straightens your arm out.
