SKULL Occipitofrontal Pineal Half-axial Lateral. Trauma and perhaps disease can likely be excluded congenital or epigenetic variation is more of a probable cause. ISOCENTRIC TECHNIQUE Basic equipment positions. Possible explanations for the presence of this anomaly are explored. Based on observations during ongoing research by the second author, this specimen was seen to exhibit a twinned right external auditory meatus. The ear is anatomically divided into three portions: External ear. The main functions of the ear are, of course, hearing, as well as constantly maintaining balance. It is situated bilaterally on the human skull, at the same level as the nose. Such is the case in a cranium recovered from the archaeological site of Carthage in Tunisia. The ear is a complex part of an even more complex sensory system. In contrast to this selection of points in the interior of the skull, the Frankfort horizontal plane was drawn from the porion present at superior contour of external auditory meatusto orbitale point positoned at lower margin of orbitale.4 Because both porion and orbitale are located in the external boder of the bony framework of the face. slight in expression, other anomalies are quite striking in appearance. You will find an oval to elliptical thin, slightly opaque membranous partition (tympanic membrane or eardrum) between a cat’s ear’s external acoustic meatus and tympanic cavity. Froment, A.Ĭranial anomalies vary in degree of expression. An external auditory meatus (ear canal) extends more or less ventrally and turns essentially medially to the tympanic membrane.
