Knowledge of the anatomy laboratory animals is important for experimental research. Erectile dysfunction has been studied using penises different such as rats, mice, rabbits, dogs, etc. However, these have with characteristics to human penis. If differences are not taken into account, conclusions may be questionable. The Rhesus monkey (Macaca mulatta), due its similarities humans, could a good model. To characterize and quantify components penis qualifying it model studies. Ten adult were...

A onça-parda (Puma concolor) é a segunda maior espécie de felídeo no Brasil, podendo ser encontrada em algumas regiões da América do Norte, estando amplamente distribuída toda Sul. Estudos morfológicos envolvendo felinos silvestres são importantes, pois contribuem para compreensão das características ecológicas uma espécie. O trabalho teve como objetivo determinar as variáveis morfométricas e vascularização renais onça-parda. Durante dissecção realizada laboratório, observou-se morfologia...

Rabbits have been used as an experimental model in many diseases and for the study of toxicology, pharmacology surgery universities. However, some aspects their macro anatomy need a more detailed description, especially abdominal pelvic arterial vascular system, which has huge variability distribution trajectory. Thirty cadaveric adult New Zealand rabbits, 13 male 17 female, with average weight rostrum-sacral length 2.5 kg 40cm, respectively, were used. The thoracic aorta was cannulated...

After 10 weeks, killed using sodium thiopenthal. Midshaft...

Variations of the renal veins are well described in literature, although variations concerning ureter considered a rare finding cats. The circumcaval is one rarest and characterised by loop posterior to caudal vena cava. This variant also known as preureteral cava retrocaval ureter. It thought be caused deviation during embryonic development aforementioned vein. Due its rarity, there scarce reports cats, association with two makes it less common well. These should preoperatively identified...

Descriptive and comparative analyses showed similarity with other canids terms topography tendon insertions. Differences domestic dog observed pectoralis profundus, triceps brachii interflexorii muscles. Intraspecific variations rhomboideus capitis, serratus ventralis cervicis, extensor carpi radialis, digiti I II, lumbricales, flexor brevis, abductor V muscle architecture carried...

Twenty thoracic limbs of ten Lycalopex gymnocercus were dissected to describe origin and distribution the nerves forming brachial plexuses. The plexus resulted from connections between ventral branches last three cervical (C6, C7, C8) first nerve (T1). These connected suprascapular, subscapular, axillary, musculocutaneous, radial, median ulnar intrinsic musculature brachiocephalic, thoracodorsal, lateral thoracic, long cranial pectoral caudal extrinsic musculature. C7 contribute most...

Objectives This study was undertaken to verify the possible modifications caused by hormonal deprivation in extracellular matrix penises of neutered cats. Methods Twenty-seven from domestic shorthair cats were collected: 14 samples intact and 13 Sections stained with Weigert’s resorcin-fuchsin, hematoxylin eosin, picrosirius red. Histomorphometric analysis performed using light microscopy image software. The following parameters analyzed: density elastic fibers collagen corpus spongiosum;...

The brachioradialis is an important muscle that acts in the external rotation of forearm (supination). However, its occurrence controversial and little studied order Carnivora. Thus, this study investigates anatomo-functional arrangement wild carnivorans species. Fifty-eight thoracic limbs specimens from species Canidae, Procyonidae, Mustelidae Felidae were dissected. Measurements length (ML), (FL), latero-medial width (MW) lateral-medial diameter (FD) obtained to establish ratios MW/FD...

Morphology studies provide knowledge that allows us to understand how animals interact with their natural environment or in captivity. In this context, comparative anatomy on the formation of brachial plexus has been a matter interest since 19th century, and remains one most intriguing topics contemporary anatomy. The aim study was describe origin antimeric distribution nerves Macaca mulatta, as well muscles innervated by it. Ten male rhesus monkeys (Macaca mulatta) were used. Animals came...

The aim of this study was to evaluate the impact body condition on pregnancy rate Nellore cows, commercial herd undergoing artificial insemination programs in fixed time (TAI). 181 cows were used multiparous Nellore, coastal plains region state Rio de Janeiro, with more than one hundred days after birth, kept pasture and divided into two groups subjected same synchronization protocol for TAI (D0-2 , 0 mg estradiol benzoate + device 1.0 g bovine intravaginal progesterone implant removal...

Background: Considered the most common congenital testicular abnormality of companion animals and a predisposition factor to development neoplasia, cryptorchidism is defined as non-descent one or both testes their normal anatomical location. Data on occurrence in Brazil are scarce. The purpose this work was verify dogs different sizes breeds. Materials methods: Cryptorchidism identification carried out by ultrasound scanning, from November, 1994 March, 2007, at Centre for Veterinarian...

PURPOSE: To update the gross and sonographic anatomy propose landmarks to perform ultrasound-guided (US-guided) axillary brachial plexus block (BPB) in rabbits. METHODS: Forty New Zeeland's rabbit (NZR) cadavers were dissected nerves trimmed, identified, measured, photographed. Additionally, twenty NZRs, images of (BP) performed through a simple-resolution ultrasound device. The US-guided was achieved minimum volume lidocaine necessary surround BP roots. effectiveness assessed on sensitivity...
