The occipital bone forms the region of the back of the head. It consists of three parts-the squamous part, the basilar part and the two condylar parts on either side of the foramen magnum. The squamous part of the occipital bone consists of two parts-the upper interparietal and the lower supraoccipital part. Usually the interparietal part fuses with the supraoccipital part but sometimes it may remain separated by a suture. Then it is called interparietal bone or Inca bone. AIM & OBJECTIVES: The aim of the present study is to find out the incidence of interparietal or Inca bones in this part of north east India as data regarding its incidence rate and number of fragments of Inca bones from Assam is still underreported. MATERIALS & METHOD: In the present study, a total of 126 dry adult skulls were examined to know the incidence of Inca bones. All the specimens were procured from various departments in Assam Medical College, Dibrugarh, Assam. They were first examined for presence or absence of Inca bones and then for number of fragments. RESULTS & OBSERVATIONS: The incidence of Inca bone was found to be 1.58%. One skull presented with a single triangular Inca bone while another skull presented with two fragments of Inca bones. CONCLUSIONS: The knowledge regarding interparietal bones and that it may present with many fragments is certainly very useful for neurosurgeons, radiologists and anthropologists.
BACKGROUNDThe styloid process is a slender, pointed bony projection that extends downward and forward from the inferior surface of the petrous part of the temporal bone, anterior to the stylomastoid foramen. The normal length of the styloid process ranges from 20 -30 mm. It is said to be elongated if it measures > 30 mm. An elongated styloid process could compress the important structures in its vicinity and give rise to a number of clinical symptoms described as the Eagle's syndrome. Severe cases of Eagle's syndrome call for surgical excision of the styloid process. Aim-The present study is aimed to find out the incidence of elongated styloid process in the population of North-East India, as stylalgia can be a disturbing complaint. MATERIALS AND METHODSThe study was carried out on 140 dry human skulls with intact styloid processes, procured from the Department of Anatomy,
BACKGROUND The Upper Assam region is known for different tribes and groups with distinct genetic makeup. No systematic study of human kidneys in the population of this part of India has been carried out before. The present work is an attempt to study the kidneys of young human adult population of Upper Assam region of India with the following aims and objectives. Aims and Objectives: 1. To study the normal gross kidney morphology. 2. To study the diameter of the cortical renal corpuscles. 3. To study the differences between the right side and left side and male and female kidneys. MATERIALS AND METHODS Kidneys were collected from Forensic Department of a referral hospital of the region. The kidneys were cleaned of the extra tissues attached to it. The length, breadth and thickness were measured using Vernier calipers and weight was measured using electronic weighing machine. The kidney tissues were sectioned with a thickness of 5 microns and examined under low power microscope. Diameters of cortical renal corpuscles were measured using Motic software (Motic Images Plus-Version 2). The average morphological parameters and diameters of renal corpuscles were calculated and compared with the opposite side and sex using unpaired 't' test. RESULTS In the present study, no significant differences of morphological parameters were observed when compared with the opposite side and sex. Average diameter of cortical renal corpuscles of the left and right kidneys were found to be 120.73 um and 121.68 um respectively. Average diameter of the renal corpuscles in female on both left and right side were slightly less than that of the average diameter of the renal corpuscles in male. No significant differences in the diameter of cortical corpuscles were observed among the study groups. CONCLUSION The gross morphological measurements of kidneys observed in young human adult population of Upper Assam region were found to be less than that of the observations by other authors of other regions. The diameters of the renal corpuscles in the present study were also much less than that of the findings of other authors. This difference is probably due to difference in study population.
