1. The neck is the part between the head and the trunk; the front part is called the larynx, behind this is the esophagus. The voice and the breath pass through the front part, the trachea, which is cartilaginous, but the esophagus is fleshy, and placed farther in, near the vertebra of the neck . The back of the neck is called the epomis. These are the parts as far as the thorax. The parts of the thorax are some before and some behind. First of all, below the neck is the breast with two mammæ; on these are two nipples, through which the milk of the female passes. The mamma is porous. There is also milk in the breasts of men. The flesh of the mamma in men is thick, in women it is spongy and full of pores.
2. The part below the thorax, in front, is the belly, and of this the navel is the centre. Beneath this centre, the part on each side is called the iliac region; the part in the centre, beneath the navel, is called the hypogastric region; the lowest part of this is called pubes; above the navel is the epigastric region; the lumbar region is situated between the epigastric and iliac regions.
3. Of the hinder parts the loin forms the division of the body, whence also its name is derived (in Greek). The part of the central region which is like a seat is the buttock; that on which the thigh turns, the cotyledon. The peculiar part of women is the uterus; of men the penis, it is external, at the extremity of the trunk in two parts; the upper part is fleshy and smooth, and is called glans; this is covered with an anonymous skin, which, if it is cut asunder, does not unite again, neither does the cheek nor the eyelid.
4. Common to this and the glans is the prepuce, the remaining part is cartilaginous, readily increases in size, and it is drawn in and out, contrary to that of the class of animals called lophuri. Beneath the penis are two testicles, surrounded by a skin called the scrotum; the testicles are not of the same nature as flesh, nor are they made of flesh. In another place we shall treat of the nature of all these parts more accurately.
5. The pudendum muliebre is contrary to that of the male, for it is hollow under the pubes, not projecting like that of the male, and the urethra is outside thewomb, for the passage of the semen of the male, and for the fluid excrement of both. The part of the body which joins the neck and the breast is called the jugulum; that which unites the side, the arm, and the shoulder is the arm-pit. The region between the thigh and the hypogastric region is calledthe groin; thepart common to the thigh and the buttock on the inside is the perineum, that of the thigh and buttock on the outside is called hypoglutis.
6. We have previously treated of the trunk. The hinder part of the breast is called the back: the parts of the back are two shoulder blades and the back-bone; below the thorax, and opposite the stomach, are the loins; the ribs belong both to the back and the front of the trunk, and are eight on each side, for we have never heard anything worthy of credit concerning the Ligyes, who are said to have seven ribs.
