(7) Toral neurons project to the secondary visceral nucleus of the isthmus and to the central and anterior thalamic nuclei of the dorsal thalamus.
(8) However, of the four children with a residual gradient greater than 20 mm Hg, two were the youngest in the study, and in two the aorta was inadvertently dilated with a balloon 4 to 5 mm smaller than the isthmus diameter.
(9) Ventilatory conditions, or the existence of soft tissue density, were evaluated by HRCT at such locations as the supratubal recess, mesotympanum, anterior and posterior parts of the tympanic isthmus, epitympanum, and mastoid antrum.
(10) Ganglion cells innervating the posterior canal were located in the caudal part of the inferior ganglion, while those cells innervating the saccule were located in the rostral part of the inferior ganglion, scattered in the superior ganglion, and concentrated at the junction (isthmus) between the two.
(11) Examination of the characteristics of the EP reveals that there is a significantly higher proportion located in the isthmus in the group of patients without an IUD, whereas the fimbrial location is more frequent among patients with an IUD.
(12) In addition, labelled cells were found in the torus semicircularis, in and around the nucleus isthmus pars parvocellularis.
(13) Ova were consistently recovered from the ampulla 24 hours after ovulation, from both the ampulla and isthmus at 48 hours, and from the uterus 72 hours after ovulation.

(15) A biopsy was taken from the mucosa of the intramural part, isthmus, and ampulla in each tube.

(18) One of them was located at mid-descending thoracic aorta and another was aortic isthmus.
(19) Coitus induced ovulation produced a characteristic oviductal motility pattern consisting of (i) initial relaxation of both isthmus and ampulla (4-12 h) followed by (ii) increased isthmic motility in the face of a continually relaxed ampulla (36-48 h), and finally phase (iii) leading to restitution of both ampullary and isthmic motility to the base-line at 72-96 h. Estimation of ova positions indicated the presence of fertilized eggs in the ampulla and ampullo-isthmic junction at 48 h and the ova could come to the end of the isthmic segment only at 72 h or after.
(20) By their nature, intracoronal restorations provide resistance to nonaxial dislodging forces, and features such as the occlusal isthmus and proximal boxes and grooves will obviously also increase this resistance.
