Morfologia dos músculos superficiais do Quati (Nasua nasua)

Abstract

The coati is an animal that belongs to the Phylum Chordata, the Mammalia Class, the Carnivorous Order and the Procyonidae Family. The striking feature of the Procyonidae family is the presence of five digits in the paws, that is, these animals are classified as plantigrade, being able to perform manual movements in different directions. He has habits of climbing trees to breed, escape danger and stay overnight. It feeds on fruits, small vertebrates, insects, nectar, eggs and vegetables. For this work, 3 orthothanized animals were used, coming from the Scientific Creatory (CECRIMPAS) - UNIFEOB authorized by IBAMA as Process: nº 02027.003731 / 04-76. The techniques used were latex injection into the abdominal aorta to replenish the arterial bed, followed by fixation in a 10% formaldehyde solution. Muscles are individualized structures that cross one or more joints and by their contraction are able to transmit movements. In the coati the superficial muscles are: platysma, cutaneous trunk, orbicularis eye, orbicularis mouth, zygomatic, masseter, nasolabial lifter, pectoralis, abdominal, deltoid, brachycephalic, great dorsal, triceps brachial, biceps brachii, extensors, flexors, brachial, semitendinosus, semimembranosus, sartorius, biceps femoris, quadriceps, tensor fascia lata, gluteus. In this species studied, anatomical adaptations were found in the brachial and pelvic muscles that developed more than the other species (Puma, Alpaca, Dog, Cat), due to their climbing habit.
