Based on the myocardial architecture, the myogenic heart of fish may be divided into four principal chambers arranged in series: the sinus venosus, the atrium, the ventricle, and the bulbus cordis (cous arteriosus) in elasmobranches and dipnoans, and in teleosts, the bulbus arteriosus (see also DESIGN AND PHYSIOLOGY OF THE HEART | Cardiac Anatomy in Fishes) bul·bus cor·dis. a transitory dilation in the embryonic heart where the arterial trunk joins the ventral roots of the aortic arches.

von lateinisch: bulbus - Zwiebel, cor - Herz Englisch: bulb of heart. 1 Definition. Der Bulbus cordis ist eine Embryonalstruktur, die nach der Ausbildung der Herzschleife kranioventral des Primitivventrikels liegt. Aus dem Bulbus cordis und dem Primitivventrikel formen sich die späteren Herzventrikel. siehe auch: embryonale Herzentwicklung. 2 Embryologi Bulbus cordis elongates and this part can be divided into: 1. Proximal bulbus cordis, 2. Middle conus cordis and 3. Distal truncus arteriosus
The bulbus cordis (the bulb of the heart) lies ventral to the primitive ventricle after the developing heart assumes its S-shaped form. Together, the bulbus cordis and the primitive ventricle give rise to the ventricles of the formed heart.The superior end of the bulbus cordis is also called the conotruncus.. The adjacent walls of the bulbus cordis and ventricle approximate, fuse, and finally. Estructura . En el corazón tubular temprano , el bulbus cordis es la vía de salida principal.

The bulbus cordis (to some extent) and the ventricle of the embryonic heart forms the main propulsive mechanism of the heart, while the atrium and sinus comprises the blood receiving areas The bulbus cordis forms the right arm of the U shaped heart tube and the primitive ventricle forms the left arm This looping of the bulboventricular segment causes the atrium and sinus venosus to become dorsal to the heart loop At this stage, the paired sinus venosus extends laterally and gives rise to the sinus horn The primitive ventricle or embryonic ventricle of the developing heart, together with the bulbus cordis that lies in front of it, gives rise to the left and right ventricles. The truncus arteriosus and bulbus cordis are divided by the aorticopulmonary septum. It develops from the bulbus cordis
Structure . In the early tubular heart, the bulbus cordis is the major outflow pathway. It receives blood from the primitive ventricle, and passes it to the truncus arteriosus. After heart looping, it is located slightly to the left of the ventricle.. Development . The early bulbus cordis is formed by the fifth week of development. The truncus arteriosus is derived from it later Bulbus Cordis Called Bulbar ridges These ridges are derived mainly from the neural crest The bulbus cordis is also some times named conus and therefore The ridges developed inside it are also called conal. And with those developed in the truncus arteriosus they also together calle

Embryology (from Greek ἔμβρυον, embryon, the unborn, embryo; and -λογία, -logia) is the branch of biology that studies the prenatal development of gametes (sex cells), fertilization, and development of embryos and fetuses.Additionally, embryology encompasses the study of congenital disorders that occur before birth, known as teratology The cardiovascular system is the first organ system to become fully functional in the vertebrate embryo and its development occurs in a similar way in all vertebrates. It is derived from angioblastic tissue, which arises from mesenchyme, an aggregation of mesenchymal cells derived from the mesodermal tissue of embryos.

The bulbus cordis section will form the right ventricular cavity, as well as the right and left ventricular outflow tracts (conus cordis). At approximately 28 days gestational age, the truncus arteriosus will divide to form the great vessels of the heart, the aorta and pulmonary artery.

Find Bulbus Cordis publications and publishers at FlipHTML5.com, download and read Bulbus Cordis PDFs for free The primitive ventricle is separated from the next region, called the bulbus cordis, by the bulboventricular sulcus. The first part of the bulbus cordis forms the right ventricle, as well as the outflow tracts for both ventricles The bulbus cordis and primitive ventricle are in communication with each other and form a common ventricle. There is a median ridge on the floor of the common ventricle near the apical aspect of the chamber. This is known as the muscular interventricular septum which is subsequently populated by myocytes.

Apoptosis in portions of each of the tubes results in their fusion to form a single heart tube suspended by a temporary dorsal mesocardium in the newly formed pericardial cavity (Figure 6-4).
