Trachea front and sides of the trachea to protect and maintain the airway. In front of the rings lies connective tissue and skin. Several other structures pass or sit over it; the jugular arch, which joins the two anterior jugular veins, sits in front of the upper part of the trachea. The sternohyoid and sternothyroid muscles stretch along its length, and the thyroid gland sits below this; with the isthmus of the gland overlying the second to fourth rings. The first tracheal ring is broader than the rest, and often divided at one end; it is connected by the cricotracheal ligament
Catholic theology of the body creation of God. God created the body like a work of art in his image. This creation reflects God’s intelligence. The human body is (eikon) somehow similar to God. To be completed as a mirror of him, is the task for every Christian. Unlike the human body, the soul is an image of God. The body cannot be an image of God, otherwise God would look like a human being with a human body. Only the soul can see God, but it is caught between the flesh and spirit. It constantly has to make a choice between the two. Origen
