ABSTRACT
The binturong or bearcat is the largest species of the family Viverridae. It is uncommon in much of its range and has been assessed as vulnerable on the IUCN red list. The size of the head was small, narrow and light in proportion to the body. The skull of the binturong was dolichocephalic as per the cephalic index (56.25). There was no prominent internasal suture and the orbits were incomplete with optic foramen present near the ventral surface. The mean skull length, skull width, skull base length, cranial length, cranial width, cranial height, were 14.95±0.10 cm, 8.47±0.10 cm, 15.07±0.02 cm, 11.16±0.09 cm, 6.56±0.11 cm, 3.16±0.08 cm, respectively. The mean facial length, facial width, maxilla length, maxilla height, distance between infraorbital foramen, diameter of infraorbital foramina, nasal length, nasal width were 4.95±0.08 cm, 6.14±0.12 cm, 4.46±0.01 cm, 3.83±0.02 cm, 4.68±0.10 cm, 0.49±0.07 cm, 2.94±0.03 cm, 1.97±0.11 cm, respectively. Scanty literature available on morphological and morphometrical studies of the skull of binturong. Therefore this present study was aimed to establish a morphometric database that will eventually guide the use of these measurements for diagnosis and treating different disorders
ABSTRACT
The aim of the research was to investigate the gross morphological, histological and histochemical structure of epididymis in local pig of Mizoram. The epididymis was collected from six apparently healthy adult Zovawk pigs. The epididymis appeared as a straight elongated tubular structure with reddish-white colour comprises of three regions; head, body and tail. The biometrical parameter including the weight, length and thickness (head, body and tail) were found to be higher in the left side of epididymis than the right side. Histologically, the duct of epididymis was surrounded by irregularly arranged tissue. The parenchyma of epididymis consists of tubules with distinct boundaries of connective tissues. The collagen and reticular fibers were abundant in tunica albuginea and connective tissue present between the tubules. However, few elastic fibers occurred in the capsule and only in the blood vessels in both the left and right epididymis of Zovawk pig. Histochemical studies revealed that basement membrane of tubules, blood vessels and stereocilia shows strong Periodic acid Schiff activity, whereas the basement membrane of tubules and stereocilia showed more concentration of acidic mucopolysaccharides. This is the first study to provide the detailed morphological, histological and histochemical structure of Zovawk epididymis
ABSTRACT
The Malayan sun bear is the smallest of the eight bear species. The aim of the research was to investigate the morphological and applied anatomical characteristics of the head region of the Malayan sun bear. The size of the head is large, broad and heavy in proportion to the body. The skull of the Malayan sun bear was mesocephalic according to the cephalic index (80.48). The skull length, skull width, cranial length and maximum skull height was 21.47 cm, 17.28 cm, 17.81 cm and 9.40 cm, respectively. The nasal length, nasal perpendicular height, nasal horizontal-transverse width and nasal circumference were 3.59 cm, 3.50 cm, 3.20 cm and 10.52 cm, respectively. The length and height of the mandible were 14.65 cm and 7.09 cm, respectively. There is no literature available on the regional applied anatomy of maxillofacial and mandibular regions of the Malayan sun bear. Therefore, this study was designed to provide information on morphological and applied anatomical studies on the head region of the Malayan sun bear. This is the first detailed study to provide morphological characteristics of the head region of Malayan sun bear and this information will aid the clinicians in the application of regional anaesthesia in Malayan sun bear
ABSTRACT
SUMMARY: Zovawk is newly identified breed of pig of Mizoram approved by breed registration committee of Indian Council of Agricultural Research (ICAR), New Delhi. This study was designed to provide maximum number of morphometrical parameters of skull and some valuable information on clinically important parameters of Zovawk. The skull of the Zovawk was dolichocephalic according to the cephalic index (53.56±0.11). The supraorbital foramina distance, infraorbital foramina distance, skull length, skull width, cranial length and nasal length of the Zovawk were 3.49±0.01 cm, 6.55±0.01 cm, 28.26±0.03 cm, 15.11±0.26 cm, 13.17±0.04 cm and 13.79±0.02 cm, respectively. The orbital margins were found to be incomplete with bilateral variation among the orbits of both the sides. The distance from the process of alveolar socket of canine tooth to the infraorbital canal and from the latter to the root of the fourth upper premolar alveolar tooth directly ventral to it was 4.77±0.04 cm and 1.20±0.01 cm, respectively in Zovawk. The data are of clinical importance as a guide for tracking the infra-orbital nerve, and necessary for its desensitization during the manipulations in the skin of the upper lip, nostril and face at the level of the foramen. The distance between the lateral end of the alveolus of the third incisor tooth to the mental foramen was 3.57±0.04 cm in Zovawk, which is an important landmark for achieving the location of the mental nerve for the regional nerve block Zovawk. The length and height of the mandible were 25.02±0.09 cm and 10.54±0.07 cm, respectively in Zovawk. The morphometric measurements of the skull and applied anatomy of the head region of the Zovawk provide an important baseline data for further research in the field of applied anatomy.
RESUMEN: Zovawk es una raza de cerdo de Mizoram recientemente identificada, aprobada por el comité de registro de razas del Consejo Indio de Investigación Agrícola (ICAR), Nueva Delhi. Este estudio fue diseñado para proporcionar el número máximo de parámetros morfométricos del cráneo y cierta información valiosa sobre parámetros clínicamente importantes de Zovawk. El cráneo de Zovawk es dolicocefálico según el índice cefálico (53,56 ± 0,11). La distancia de foramina supraorbital, la distancia de foramina infraorbital, la longitud del cráneo, el ancho del cráneo, la longitud craneal y la longitud nasal del Zovawk fueron 3.49 ± 0.01 cm, 6.55 ± 0.01 cm, 28.26 ± 0.03 cm, 15.11 ± 0.26 cm, 13.17 ± 0.04 cm y 13.79 ± 0,02 cm, respectivamente. Se encontró que los márgenes orbitales estaban incompletos con una variación bilateral entre las órbitas de ambos lados. La distancia desde el proceso de la cavidad alveolar del diente canino al canal infraorbitario y desde este último a la raíz del cuarto diente alveolar premolar superior directamente ventral fue de 4.77 ± 0.04 cm y 1.20 ± 0.01 cm, respectivamente, en Zovawk. Los datos son de importancia clínica como guía para el seguimiento del nervio infra-orbital y necesarios para su desensibilización durante las manipulaciones en la piel del labio superior, fosa nasal y cara a nivel del foramen. La distancia entre el extremo lateral del alvéolo del tercer diente incisivo y el foramen mental fue de 3.57 ± 0.04 cm en Zovawk, que es un hito importante para lograr la ubicación del nervio mental para el bloqueo nervioso regional Zovawk. La longitud y la altura de la mandíbula fueron 25.02 ± 0.09 cm y 10.54 ± 0.07 cm, respectivamente, en Zovawk. Las mediciones morfométricas del cráneo y la anatomía aplicada de la región de la cabeza de Zovawk proporcionan datos de referencia importantes para futuras investigaciones en el campo de la anatomía aplicada.
