They pass laterally and slightly upward, over the crura of the diaphragm, to the suprarenal glands,... -
Ulnar artery
The ulnar artery is the main blood vessel, with oxygenated blood, of the medial aspect of the forearm. It arises from the brachial artery and terminates in the superficial palmar arch, which joins with the superficial branch of the radial artery.

Azygos arteries of the vagina
The uterine artery supplies branches to the cervix uteri and others which descend on the vagina; the latter anastomose with branches of the vaginal arteries and form with them two median longitudinal vessels—the vaginal branches of uterine artery (or azygos arteries of the vagina)—one of which runs... -
Left marginal artery

Deep auricular artery
The deep auricular artery often arises in common with the anterior tympanic artery. It ascends in the substance of the parotid gland, behind the temporomandibular articulation, pierces the cartilaginous or bony wall of the external acoustic meatus, and supplies its cuticular lining and the outer... -
Deep artery of the penis
The deep artery of the penis (artery to the corpus cavernosum), one of the terminal branches of the internal pudendal, arises from that vessel while it is situated between the two fasciæ of the urogenital diaphragm (deep perineal pouch). It pierces the inferior fascia, and, entering the crus penis... -
Medial palpebral arteries
The medial palpebral arteries (internal palpebral arteries) are arteries of the head. They are two in number, superior and inferior, arise from the ophthalmic, opposite the pulley of the Obliquus superior. They leave the orbit to encircle the eyelids near their free margins, forming a superior and... -
Posterior interosseous artery
The posterior interosseous artery (dorsal interosseous artery) is an artery of the forearm. It passes backward between the oblique cord and the upper border of the interosseous membrane.
