The tympanic artery is a very small vessel which passes along the Eusta- chian tube to the i:)ctro-tynipanic fissure and enters the middle ear. 4. The middle meningeal artery (A. meningea media) arises beneath the buc- cinator nerve, where the internal maxillary turns forward.

The tympanic artery is a very small vessel which passes along the Eusta- chian tube to the i:)ctro-tynipanic fissure and enters the middle ear. 4. The middle meningeal artery (A. meningea media) arises beneath the buc- cinator nerve, where the internal maxillary turns forward. It passes backward across the temporal wing of the sphenoid to the antero-lateral part (foramen spino- sum) of the foramen lacerum. Entering the cranium, it divides into branches which course in the grooves on the temporal and parietal bones and supply the dura mater. It anastomoses with the posterior meningeal. The size of this artery is variable, and is in inverse ratio to that of the posterior Fig. 565.—Sagittal Section of Head of Horse, Cut a Little to the Right of the Median Plane. ; 5, nasal bone; 3, frontal bone; 4, parietal bone; 4'. tentorium osseum; J, occipital bone; 5, sphenoid bone; 7, hard palate: S, premaxilla; 9, mandible; 10, hyoid bone; 11, septum between frontal sinuses; 12, alar cartilage; 13, transversus nasi; 1^, septum nasi with venous plexuses; 15, palato-labiai artery; 16, 16', upper and lower septal branches of/5; i7, septal branch of sphenopalatine artery and satellite vein; IS, septal branch of ethmoidal artery; 19, sphenoidal sinus: iO, guttural pouch; £1, pharynx; 23, pharyngeal orifice of Eustachian tube; 23, posterior naris; 24, soft palate; 25, palatinus muscle; 26, pharyngeal muscles; 27, cesophagus; 3S, dotted line indicating posi- tion of posterior pillar of soft palate: 29, lamina, 29', arch of cricoid cartilage: SO, arytenoideus transversus muscle; 31, epiglottis: 32, body of thyroid cartilage; 33, vocal process and cord; 34, arytenoid cartilage; 35, lateral ventricle of larynx; 36, trachea; S?, ventral straight muscles of head; 3S, longus colH; 39, atlas; 40, axis; ^-f. lig-nuchse; 42, dorsal spinal muscles; 4^, muscles of external ear
