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 two sides connect at the sternum, or breastbone. The pectoralis major moves each shoulder joint in four distinct directions, and also keeps the arms attached to the body. Injuries to this muscle are rare, but symptoms include pain in the chest, bruising, and decreased strength of the muscle. The pectoralis minor is located underneath the pectoralis major. This thin triangle-shaped muscle runs up and down along the upper ribs. The major muscles in the upper torso include: 1  Trapezius: This muscle extends across the neck, shoulder, and back. 2  It allows for movement of the shoulders and shoulder blades. 3  Rhomboid major: Attached to the shoulder blade, this muscle is one of many that aids shoulder movement.
