tinuing

the direction of the s. cinguli from where the pars marginal is of that fi ure bends upward; it forms the upper boundary of the posterior portion of the gyrus cinguli. the under surface of the astragalus giving attachment to the intero eous ligament. occipitotemporal s., a sagittal fi ure on the under surface of the temporal lobe of the cerebrum, separating the inferior temporal from the fusiform (occipitotemporal) convolution. second temporal s. a sagittal fi ure on the lower part of the lateral surface of the temporal lobe of the cerebrum, separating the middle and inferior temporal convolutions. s., super temporal s., first temporal s., parallel s., a long deep fi ure running the whole length of the lateral surface of the temporal lobe of the cerebrum, parallel with the lateral (Sylvian) fi ure, separating the superior and middle temporal convolutions; its posterior extremity, running into the parietal lobe, is deflected upward and is capped by the angular gyrus. poral s., one of a number of transverse fi ures on the surface of the temporal lobe of the cerebrum bordering on the lateral (Sylvian) fi ure, running from the region of the superior temporal gyrus to the insula; they separate the transverse temporal convolutions from each other. apex pointing backward, on the surface of the tongue, marking the separation between the oral, or horizontal, and the pharyngeal, or vertical, parts of this organ; (2) a groove on the surface of the right atrium of the heart, marking the junction of the primitive sinus venosus with the atrium. the inner surface of the parietal bone, at its posterior inferior angle, which receives the lateral venous sinus. surface of the posterior border of the greater wing of the sphenoid bone, for the cartilaginous Eustachian tube. the tympanic ring in which the circumference of the drum membrane on the internal surface of the parietal bone, in which veins lie. cord.
