Anatomy & distribution of coronary arteries in pig in comparison with man.

Background & Objective: The suitability of pig as an animal model for research in coronary artery disease is well established. As coronary arteries (CAs) of the pig are reportedly closely resemble those of man. We investigated the CAs of the pig (Sus scrofa) and study differences between the two, if any.

Facial soft tissue thickness in northwest Indian adults.

In order to reconstruct the face from a bare skull, the facial soft tissue thickness (FSTT) was determined at 29 standard anthropological landmarks by magnetic resonance imaging (MRI) in 173 male and 127 female adult subjects of northwest Indian origin. Repeatability and accuracy of the measurements was assessed by paired t-test and 95% confidence intervals. A stepwise discriminant function analysis selected nine landmarks for better sex classification in FSTT measurements.

Variations and anomalies of the posterior communicating artery in Northwest Indian brains.

Background: The PCoA is a major branch of the supraclinoid internal carotid artery. Thorough knowledge of the anatomy and awareness of the variations and anomalies are of clinical importance.

Methods: The PCoA was studied in 200 male and 80 female adults and in 20 male and 25 female children.

Weight and dimensions of the pituitary in northwestern Indians.

Weight and dimensions of the pituitary (hypophysis cerebri) obtained from medicolegal autopsies of northwestern Indian subjects, which included 87 children and adolescents and 798 adults were recorded. Volume of the pituitary was determined in 100 specimens. In addition, anteroposterior and vertical measurement of pituitary were taken in mid-sagittal sections of the head in magnetic resonance images (MRI) of 130 living adults.

Filiform papillae in the mucosa of the human vaginal wall.

Background & Objective: While giving the gross anatomy of the mucosa of the vagina, textbooks of Anatomy and Obstetrics and Gynaecology describe the presence of a median longitudinal ridge on its anterior wall (columna rugarum anterior) and another similar ridge (columna rugarum posterior) on its posterior wall is described, and transverse rugae separated by sulci of variable depth, extend bilaterally from these ridges. While conducting autopsy of female cases the routine examination of vaginal mucosa did not show the presence of longitudinal ridges. In addition, some small areas bearing filiform papillae were seen in the lower third of the vagina in young subjects.
