ネコのA. malarisについて

抄録

The a. malaris of the cat was studied by utilizing the acryl plastic injection method. This artery generally arose from the infraorbital artery in common with the anterior nasal dorsal artery, or rarely in common with the anterior superior alveolar artery. It gave rise to the inferior oblique and the third palpebral branches at the superoanterior end of the origin of the obliquus inferioris muscle. The former always was a stout vessel as it was also in some mammals. The latter was especially developed in the cat and divided into the third palpebral glandular branch and others to supply the whole third palpebra. The a. malaris gave rise to the periosteal and the nasolacrimal branches on the orbital surfaces of the lacrimal and frontal bones. It finally terminated in the medial superior and inferior palpebral arteries. They, however, did not form superior and inferior arterial archs in the respective palpebra as observed in the rabbit. The medial inferior palpebral artery gave rise to the nasolacrimal, the lacrimal sac, the nasal radical, the ocular orbicular, the infraorbital marginal, the conjunctival and the cutaneous branches. The medial superior palpebral artery gave rise to thesuperior palpebral levator and the supraorbital marginal, after giving off the lacrimal sac and the nasal radical branches. The cutaneous branch anastomosed with the branches of the superficial temporal artery.
The anterior nasal dorsal artery arising in common with the a. malaris in most cases formed a fine network with many fine branches of the a. malaris, which spread on the face, especially in an area centeral to the medial canthus.
