Abstract


ABSTRAK

Jantung merupakan organ vital yang berfungsi untuk memompa darah melalui pembuluh darah. Penelitian ini bertujuan untuk mendapatkan informasi mengenai gambaran histologi dan morfologi jantung gurita (Octopus sp.) yang terdapat di perairan Lampuuk, Lhoknga, Aceh Besar. Sampel penelitian ini masing-masing berjumlah tiga ekor gurita. Jantung sistemik dan kedua jantung branchial gurita masing-masing diproses hingga menjadi sediaan histologi dengan ketebalan 5 μm, kemudian diwarnai menggunakan pewarnaan Haematoksilin-Eosin (HE). Hasil penelitian menunjukkan Jantung sistemik gurita terdiri dari tiga lapisan yaitu epikardium, miokardium dan endokardium. Lapisan epikardium terdiri dari mesothelium dan jaringan ikat. Lapisan miokardium terdiri dari otot-otot jantung. Lapisan endokarkardium terdiri dari endothelium, jaringan ikat dan lapisan subendokardium. Sedangkan kedua jantung branchial gurita terdiri dari lapisan jaringan ikat, lapisan otot dan lapisan sel bundar yang berukuran besar, tidak terdapat struktur yang berbeda antara kedua jantung branchial gurita. Sehingga dapat disimpulkan bahwa Jantung sistemik gurita terdiri dari tiga lapisan yaitu epikardium, miokardium dan endokardium. Sedangkan jantung branchial gurita terdiri dari lapisan jaringan ikat, lapisan otot dan lapisan sel bundar yang berukuran besar.

Kata kunci : Gurita, histologi, jantung branchial, jantung sistemik, morfologi.

ABSTRACT

The heart is a vital organ that functions to pump blood through blood vessels. This study aims to obtain information about the histology and morphology of the octopus’s (Octopus sp.) heart coastal area of Lampuuk, Lhoknga, Aceh Besar. The samples of this study amounted to three octopus each. The systemic heart and the two branchial hearts of each octopus were processed into histological preparations with a thickness of 5 μm, then stained using Haematoxylin-Eosin (HE) staining. The results showed that the systemic heart of octopus consists of three layers, namely epicardium, myocardium and endocardium. The epicardium layer consists of mesothelium and connective tissue. The myocardium layer consists of the heart muscles. The endocardium layer consists of the endothelium, connective tissue and subendocardium layers. While the two octopus branchial hearts consist of a layer of connective tissue, a layer of muscle and a layer of large round cells, there are no different structures between the two octopus branchial hearts. So it can be concluded that the octopus systemic heart consists of three layers, namely epicardium, myocardium and endocardium. Meanwhile, the octopus branchial heart consists of a connective tissue layer, a muscle layer and a layer of large round cells.
