Situs inversus is a congenital positional anomaly characterized by transposition of abdominal viscera and when associated with right sided heart (Dextrocardia) is referred to as Situs inversus totalis. It is not so uncommon congenital positional anomaly but can be a diagnostic problem at times. The case was detected in the Department of Anatomy, Gauhati Medical College during the routine dissection. Situs inversus was first described by Aristotle in animals and by Fabricius in humans. Its incidence has been reported between 1 in 4000 to 20,000 live births. The exact etiology is unknown but Autosomal recessive and X-linked inheritance have been reported. It can also occur in association with syndromes such as Kartagener syndrome or Primary Ciliary Dyskinesia (PCD). Many people with situs inversus totalis are unaware of their unusual anatomy until they seek medical attention for any condition.

Background and aims: The uterus is subjected to a wide range of normal variation in both its anatomy and physiology e.g. the changes of childhood to puberty and into the reproductive years, the variations of menstrual cycle, the changes consequent to pregnancy and parturition and fmally regression associated with menopause and postmenopausal years. It is a very important organ of female reproductive system and is subjected to investigation for size, shape and position in cases of infertility. The study of normal morphological architecture is of prime importance to have the basic knowledge of the various pathological entities. Materials and methods : 30 samples each from reproductive and postmenopausal women were collected from fresh unembalmed human cadavers. Biometrical values of the two different groups were recorded and statistically analyzed for Mean. The 'z' test was employed to find out the significant difference between mean values of length, breadth, thickness and weight. Results: The Length, Breadth , Thickness and weight of uterus in Reproductive age group and Post - menopausal age group differ significantly. The length, breadth, thickness and weight ranged from 6.2-9.0 em, 4.9-6.1 em, 2-3.5 em, 35.4-73 gm respectively in reproductive age group. In the postmenopausal group the length, breadth, thickness and weight ranged from 3.8-6.5 em, 1.8-5.0 em, 1-2.3 em, 18-40.0 gm respectively. Conclusion: A clear conception of the age related morphological changes ofuterus is a prerequisite for the radiologists for pelvic imaging and for clinicians for diagnosis and management of various diseases like benign and malignant neoplasms and infertility.

Background and aims: The "Uterus" or "Womb" is a part of the female reproductive tract that receives the fertilized ovum from the oviduct, provides the bed for implantation and establishes the vascular connections necessary for sustenance of the embryo throughout its development. Due to increasing rate of infertility, the reproductive organs are gaining importance. The aim of the study is to ascertain that the research work could be utilized for investigation and guidance for management of infertility cases. The knowledge of normal histological architecture of the uterus will be of help to isolate any pathological changes. Materials and methods: Ten samples each from reproductive and postmenopausal women were collected from fresh unembalmed human cadavers. The slides were prepared using the standard laboratory procedure. Stress was given on the structure of endometrium, cervical mucosa and squamocolumnar junction. Endometrial and cervical mucosal thickness were measured in both groups. Results: Significant differences of histological architecture were noted between the two groups. The average endometrial thickness as measured by micrometer scale was 4.29 mm and 1.64 mm in reproductive and post-menopausal women respectively. The average cervical mucosal thickness was 2.76 mm and 1.55 mm in reproductive and postmenopausal women respectively. Conclusion: Knowledge of the normal histological structure of the uterus is of prime importance to have the basic knowledge of various pathological entities.
