Skull Bones

Background: There is scanty information on the morphometry of the skull of Indian mithun; therefore, the present study was designed to provide morphometric data of the skull of Indian mithun. Methods: The study was conducted on the skull bones of twelve (n=12) adult Indian mithun of either sex (n=6, male and n=6, female). The head region samples of naturally died mithun were collected from different parts of the Mizoram and Nagaland states of India from September, 2019 to March, 2020. In the present study, altogether, a total of forty-five parameters were taken in the skull bones of males and females of Indian mithun. Result: The biometrical observations on the different parameters of the skull of Indian mithun were found to be significantly (P less than 0.01, P less than 0.05) higher in the males than females. The measurements demonstrated that the skull of the mithun was elongated and dolichocephalic as per the value of the skull index. The skull index/ cephalic index was 48.76±0.03 in males and 48.71±0.02 in females of the mithun. The length, width of the skull was 44.52±0.02, 44.41±0.02 in males and 21.62±0.04, 21.57±0.05 in females of mithun, respectively. The orbital margin was circular and complete in mithun. The cranial cavity of mithun was oval in outline with a capacity of 530.00±0.27 cm3 in males and 523.00±0.31 cm3 in females. The foramen magnum was large, roughly oval with a foramen index as 96.93±0.06 in males and 97.19±0.04 in females. The present morphometrical studies on the skull of mithun can be useful to the wildlife professionals and zoo veterinarians for the determination of sex of this animal and distinguish from other domestic and wild animals for solving veterolegal cases.

Background: There is scanty information on the skull morphology of Indian mithun. Therefore, the present study has been designed to provide information on the morphology of the skull of Indian mithun. Method: The study was conducted on the skull bones of twelve (n=12) adult Indian mithun of either sex (n=6, male and n=6, female). The head region samples of naturally died mithun were collected from different parts of the Mizoram and Nagaland states of India from April, 2019 to March, 2020. Result: The skull of mithun was roughly triangular in shape from the dorsal side. The cranial and facial bones were the major components of the skull, with a total of thirty-two bones. There were three single and four paired cranial bones with a total of eleven bones. There was one single and the rest were paired facial bones with a total of twenty-one bones. The cranial bones were occipital, parietal, interparietal, sphenoid, ethmoid, frontal and temporal. The facial bones were maxilla, premaxilla (incisive), palatine, pterygoid, nasal, lacrimal, zygomatic (malar), vomer, turbinate, mandible and hyoid. The present morphological studies on the skull of mithun can be useful to the wildlife professionals and zoo veterinarians for the determination of sex of this animal and differentiation from other domestic and wild animals for solving veterolegal cases.

Background: The topographic and morphometric anatomy of various foramina provides an easy approach in performing nerve blocks by their proper tracking for regional anesthesia in surgical interventions. There is no previously reported information on the applied anatomy and clinical significance of the maxillofacial and mandibular regions of the Indian mithun. The present study was designed to provide important clinical landmarks related to tracking of the infraorbital, mental and mandibular nerves with its clinical significance in regional anesthesia in mithun. Methods: The study was conducted on the maxillofacial and mandibular regions of twelve (n=12) adult Indian mithun of either sex (n=6, male and n=6, female). The head region samples of naturally died mithun were collected from different parts of the Mizoram and Nagaland state of India and processed as per the standard maceration technique. Altogether, a total of twelve measurements were taken in the maxillofacial and mandibular regions of mithun by using a digital vernier caliper and the results were expressed as mean±standard deviation. The obtained parameters from the present study can be useful for an extraoral and intraoral approach for nerve block of the infraorbital, mental and mandibular nerve in the maxillofacial and mandibular regions of mithun. Result: The present study revealed that all the obtained parameters related to regional anesthesia showed a significant statistical difference (P less than 0.01** and P less than 0.05*) between the males and females of mithun. It can be concluded from the present study that the various applied parameters of the present study will aid the clinicians in the implication of regional anesthesia in the head region of mithun.

Background: The present study was conducted for analysis of the morphometry shape and determination of sex by foramen Magnum. Methods: After applying inclusion and exclusion criteria 30 dried human skull of unknown age and sex were slected for present study from the Department of anatomy, S.M.S. Medical College, Jaipur, Rajasthan. In case of skull bones, all 30 cranial bases were visually assessed for FM shape classification. Each FM shape was classified into one of the 8 types: oval, egg, round, tetragonal, pentagonal, hexagonal, combination of 2 different semicircles and irregular. Results: The mean anteroposterior diameter of foramen magnum male and female skull bones were found to be 37.17±1.76 mm  and 33.92±3.50 mm respectively.The mean transverse diameter of foramen mgnum in male and female skull bones were found to be 29.49±2.68 mm and 29.38±2.47 mm respectively.The mean area of foramen magnum male and female skull bones were found to be 818.05±119.66 mm² and   847.57±105.85 mm² respectively.The mean index of foramen magnum in male and female skull bones were found to be 84.00±5.41 and 80.27±5.79 respectively.Overall skull bones showed a medium type of foramen magnum index . Conclusion: We concluded that the several anatomic parameters such as shape and dimensions of foramen magnum should be taken into consideration during surgery involving the craniovertebral junction. Also these can be used during forensic and anthropological investigation of unknown individuals for determining gender, ethnicity, etc Keywords: Skull, foramen magnum, skull.

Morphological Differences

It has been demonstrated that cross sections of bundles of hair can be effectively studied using image analysis. These studies can help to elucidate morphological differences of hair from one region of the body to another. The purpose of the present investigation was to use image analysis to determine whether morphological differences could be demonstrated between male and female human Caucasian terminal scalp hair.Hair samples were taken from the back of the head from 18 caucasoid males and 13 caucasoid females (Figs. 1-2). Bundles of 50 hairs were processed for cross-sectional examination and then analyzed using Prism Image Analysis software on a Macintosh llci computer. Twenty morphological parameters of size and shape were evaluated for each hair cross-section. The size parameters evaluated were area, convex area, perimeter, convex perimeter, length, breadth, fiber length, width, equivalent diameter, and inscribed radius. The shape parameters considered were formfactor, roundness, convexity, solidity, compactness, aspect ratio, elongation, curl, and fractal dimension.

This study examined the traditional knowledge of fishermen at Mamirauá Reserve about sex determination of pirarucus, Arapaima gigas Schinz 1822. We evaluated the criteria used for by fishermen in the sector Jarauá at Mamirauá Reserve for this determination, during the fisheries season, from October to November 2004. We analyzed responses of a group of about 15 fishermen collected in structured interviews regarding 109 individual pirarucus, 65 males and 44 females. From this sample, only 64 fish have their sex correctly predicted by the fishermen. Although the traditional knowledge of local fishermen is a key component of the sustainable fisheries of this species, this knowledge is not functional in all ranges and aspects, as in sex distinction. We found that the local fishermen evaluated are not able to recognize the sex of pirarucus, although some criteria applied for this purpose are consistent with their biology. The rates of correct forecasts for recognition of males and females were similar to those obtained by chance, even when the criteria applied were consistent, as the criterion “coloration”, which was significantly consistent for identification of males. Yet the group of fishermen interviewed in this study apparently did not apply this criterion correctly.

The aim of this study was to evaluate interrelationships of body weight and bone weight and densitometric properties of the tibiotarsus in White Koluda Geese (W31) in the post-hatching period. The study was performed using dual-energy X-ray absorptiometry (DEXA) and peripheral quantitative computed tomography (pQCT) at two different parts of tibia: proximal metaphysis and mid-diaphysis. The investigation was performed on 100 bones obtained from males and females at the age of 1, 14, 28, 42 and 56 days of life. All the calculations were performed using the Statistica 9.0 software (StatSoft, Inc. Tulsa, USA). Pearson’s correlation coefficient of body weight and bone weight with all the investigated variables of bone was determined. Depending on the method used for densitometric measurements – DEXA or pQCT, the current study has revealed significant differences in the number of correlations of bone weight and body weight with the evaluated densitometric parameters. Sex-related differences in the investigated interrelationships were also found. In the case of proximal epiphysis, negative correlations of vBMD, tBMC, CTR_DEN and CRT_CNT with body weight and bone weight dominated in one-day-old males. Based on the current observations and the negative correlations of body weight and vBMD, CRT_DEN and TRAB_DEN obtained in the mid-diaphysis of tibiotarsus at the age of 14 days of life, it was concluded that this bone is much more prone to deformations and fractures in males than in females.
