analysis of the ovary of black Bengal goat (Capra hircus). Int. J. Morphol., 34(1):13-16, 2016. SUMMARY:Ovary plays the vital role in the reproductive biology and biotechnology of female animals. With the aim to study the ovarian morphometry of Black Bengal goat, both right and left ovaries were collected from the slaughter houses of different Thanas under Mymensingh district. For each of the specimens, gross parameters such as weight, length and width were recorded. Then they were processed and stained with H & E for histomorphometry. Our study revealed that the right ovary (0.53±0.02 g) was heavier than the left (0.52±0.02 g). The length of the right ovary (1.26±0.04 cm) was lower than the left (1.28±0.02 cm) but the width of the right (0.94±0.02 cm) was greater than the left (0.90±0.03 cm). The diameter of ovarian follicles in the cortex was measured as primordial 39.6±6.61 µm, primary single layer 54.0±4.06 µm, primary multi layer 147.6±11.04 µm, secondary with C-shaped antrum 449.5±75.71 µm and tertiary follicle of ovary 1.3±0.20 mm. In the graffian follicle, the thickness of granulosa cell layer was 79.2±11.04 µm, theca interna 75.76±6.82 µm, theca externa 130.07±12.53 µm and the oocyte diameter was 109.8±5.75 µm. These results will be helpful to manipulate ovarian functions in small ruminants.

The morphology of esophagus of Black Bengal goat was studied 6 Black Bengal goats of over six months of age of both sex in the Department of Anatomy and Histology, Bangladesh Agricultural University, Mymensingh-2202, Bangladesh using. The topography, shape, size, esophageal length including cervical and thoracic parts were measured. The esophagus was sampled at six sites - cranial cervical, middle cervical, caudal cervical, at the level of thoracic inlet, at the middle mediastinum and at the level of cardia. The esophagus was 45-50 cm long. The cervical part of esophagus was 13-15 cm long and the thoracic part was 32-30 cm long. The highest and lowest diameter was found 5.1 cm and 3.2 cm at the cardia and at the cranial cervical part of the esophagus respectively.

Detail histological features of esophagus of 12 Black Bengal goats were studied in the Department of Anatomy and Histology, BAU, Mymensingh-2202, Bangladesh during the period from July to December 2003. All specimens were collected from adult Black Bengal goats (over 6 months of age) irrespective of age and sex. The esophagus of Black Bengal goat was sampled at six areas- cranial cervical, middle cervical, caudal cervical, at the level of thoracic inlet, at the middle mediastinum and at the level of cardia. The histological layers of esophagus were-tunica mucosa (lamina epithelia, lamina propria and lamina muscularis mucosa), tunica submucosa, tunica muscularis and tunica scrosa/adventitia.

Int. J. Morphol., 34(3):909-917, 2016. SUMMARY:Bones of forelimb were studied from a prepared skeleton of an adult female Asian elephant (Elephas maximus) in Anatomy Museum of Chittagong Veterinary and Animal Sciences University to understand the morphological form and structure of Asian elephant forelimb. The angle was approximately 123º between caudal border of scapula and caudal border of humerus. The scapula, humerus and bones of the antebrachium (particularly the ulna) were massive bones. The bones of manus were the short and relatively small. The dorsal border of scapula extended from the level of proximal extremity of first rib to the middle of the 6 th rib. Ventral angle of scapula articulated with humerus by elongated shaped glenoid cavity (cavitas glenoidalis) of scapula and head of humerus (caput humeri). The major tubercle (tuberculum majus) of humerus was situated laterally to the head, which had smaller cranial part with large caudal part and extended cranially to the head. The crest of minor tubercle (tuberculum minus) was present as the rough line on the mediocaudal surface of humerus that ends in a slight depressed or elevated area, known as teres major tuberosity (tuberositas teres major). The lateral supracondyler crest (crista supra condylaris lateralis) at the caudal surface of the shaft limit the musculo-spiral groove in body of humerus. The radius and ulna are twin bones of forearm and the attachment between ulna and radius occurs in such a way, the radius articulates craniomedially with the ulna in the proximal part. But the shaft spirals laterally over the cranial surface of the ulna to articulate distally with the medial aspect of the ulna. There were 8 carpal bones, 5 metacarpal bones and 5 digits. The comparative size of the proximal and distal raw of carpal bones were ulnar carpal > radial > intermediate > accessory carpal and IV > III > II > I respectively. The gradual lengths of the metacarpal bones were III > IV > II > V > I. Digits I and V were vertical and digit II, III and IV were horizontal.
