Originating from the left aortic sinus, the LCA passes between the left auricle and pulmonary trunk to traverse the coronary sulcus
(Drake et al.
Upper lip sulcus
depth (USD): The measurement between the upper lip sulcus
and a perpendicular line drawn from the vermillion to the Frankfort plane;
Perhaps, because of the small sample size and the lack of standardization of the ultrasonographic views, these studies showed significant variation in the measurements of fetal sulcus
According to Hold away, upper lip sulcus
depth has an acceptable range of 1-4 mm, with the mean of 3mm being ideal.
D J Apple et al (1985)  compared indications, advantages and disadvantages of ciliary sulcus
and capsular fixation of PC IOL.
Initial IOL implantation was in the sulcus
for 50%, in-the-bag for 27.
However the immature Sooty Albatross has a clearer pale head, gray or black sulcus
and the tail lacks pale shafts, while the adult of the Light-mantled Albatross has bluish sulcus
and white shafts (Figures 1c and d) (Harrison, 1983; Onley and Scofield, 2007).
1- Central Sulcus
; 2- pars opercularis; 3- Short gyrus of insula; 4- Central Sulcus
of Insula; 5- Long Gyrus of Insula; 6- Middle temporal gyrus (Thomas Frigeri).
There are several conventional techniques that can be used for reducing isolated zygomatic arch fractures such as: the Gillies temporal approach, hook elevation, upper buccal sulcus
technique, intranasal transantral approach, and open reduction.
Hall (1982) said that the width of attached gingiva is determined by subtracting the sulcus
or pocket depth from total width of gingiva.
Some authors presume that such meningiomas arise from arachnoid cells of the pia mater that stretches into the surface of brain or sulcus
with perforating blood vessels, while others suggest that the arachnoid cells rest in the brain during the migration progress .
