Head and body of a young girl with muscles and blood vessels

On the right half of the trunk the superficial layers can be seen. The obliquus externus abdominis is clearly visible, whose large aponeurosis covers the rectus abdominis in the middle while, below and medially, goes into the inguinal ligament (of Falloppio) forming the superficial inguinal ring. On the other side the pectoral is major muscle is hidden for the most part because over it lies the mammary gland partially dissected in order to show the vessels and the deep lactiferous ducts.

On the left, attention is drawn to deep layers of the abdomen, thorax and neck and the superficial layers of the head. In the abdomen, free large muscles have been dissected (obliquus externus, obliquus internus and transversus) and rectus abdominis removed; therefore the posterior part of the sheath of this muscle with the superior and inferior epigastric arteries connected to it can be seen. In the thorax, between the pectoral is major and the serratus anterior the costal arches are revealed under which is the internal mammary artery and, upon, the outer mammary artery.

In the neck we can see laterally the scaleni muscles and, in the middle, the longus colli and the longus capitis partly covered by the internal organs of the neck; moreover the common artery and both internal and external carotid arteries are easily recognizable.

There is also a great number of the branches of the external carotid, such as the superior thyroid artery which goes down to the thyroid and sends forth the superior laryngeal, the lingual artery hidden behind the angle of the mandible, the external maxillary artery going obliquely upwards on the face, the ascending pharyngeal artery surrounding the internal carotid, the occipital artery heading to the nape of the neck and the superficial temporal artery which branches on the temple towards the orbit.

Finally we note, resting on the dome of the pleura and partially hidden by the first part of the subclavian vein, the subclavian artery, among whose branches one can recognize the inferior thyroid artery heading towards the thyroid, the vertebral artery which goes vertically through the triangle of the vertebral artery (of Nunziante Ippolito) to get to the transverse foramen of the VI cervical vertebra, the internal mammary artery that descends behind the ribs and the superficial cervical and suprascapular arteries connected to the scalenus.

On the head the muscles of facial expression are highlighted together with the masseter and the temporal is muscle, the latter still covered by its fascia.
