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 the bicep (on top) contracts, the tricep (bottom) relaxes, thus hindering the movement of the arm, ie the lower section. By upper arm, I think you mean the part a â¦ bove your elbow. That is moved by the collar bone and no muscle is involved, although the movement described above could be considered here. ~.
