ratak-monodosico: Frontal section through the head of newborn - region of molars The big empty space is where the brain would be, if it were left in the head, just to get a general orientation. The blue circle-shaped regions shown down near the tongue cross-section are odontoblasts (tooth germs). The deciduous (baby) teeth all begin their development early in gestation. By 20 weeks into pregnancy, the initial calcification has established the tooth germs throughout the mouth. Though the crowns of the teeth (harder tissues - dentin and enamel) are not deposited until roughly 5-6 months old in the case of the first molars, you can clearly see the development of the inner tissues of the teeth going on in this cross-section.

ratak-monodosico: Sagittal Cross-Section of Lower Male Trunk If you look up near the top of the illustration, you can see the left common iliac vein. The common iliac vein consists of both the internal and external iliac veins, which consist of the small veins and capillaries that connect to the intestines. This is the blood in your body that supplies you with nutrients - the acids and enzymes in the human digestive tract break down food into molecules small enough to pass through the wall of the intestine. When blood flows down to the lower abdomen, it drops off oxygen where it’s needed, and picks up the broken-down nutrients, before flowing to the organs where the nutrients will be processed, through the inferior vena cava. [De-oxygenated blood returns to the heart via the superior vena cava, not inferior.] Applied Surgical Anatomy, Regionally Presented, for the use of students and practitioners. George Woolsey, 1902.
