Em nosso laboratório de dissecção do estômago lagosta é feito para acessar o sistema nervoso stomatogastric, uma rede que controla as contrações rítmicas do estômago. A anatomia do estômago lagosta foi bem descrito anteriormente 5-7, e nós recomendamos familiarizar-se com sua anatomia. Se o fizer, irá reduzir o risco de danificar os delicados nervos e músculos. Após a conclusão da dissecção do estômago, várias partes do STNS pode ser ainda mais dissecados. Por e...

gross dissection of the stomach of the lobster, homarus americanus

O estômago da lagosta americana (<i&gt; Homarus americanus</i&gt;) Está localizado no cefalotórax, entre a tribuna eo sulco cervical. A extremidade anterior do estômago é definida pela abertura da boca e da extremidade posterior por parte inferior do piloro. Ao longo do lado dorsal do estômago se encontra o sistema nervoso stomatogastric (STNS). Este sistema nervoso, que contém as redes que estão na base rítmica comportamento alimentar, é um sistema modelo estabelecido para o estudo de redes ritmo de geração e neuromodulação<sup&gt; 1,2</sup&gt;. Embora seja possível estudar este sistema<i&gt; In vivo</i<sup&gt; 3</sup&gt;, O STNS continua a produzir a sua atividade rítmica quando isolados<i&gt; In vitro</i&gt;. Para estudar este sistema<i&gt; In vitro</i&gt; O estômago deve ser removido do animal. Este artigo descreve como vídeo do estômago pode ser dissecada da lagosta americana. Em um artigo de vídeo que acompanha<sup&gt; 4</sup&gt; Demonstramos como o STNS pode ser isolado do estômago.
