The human body contains two large hollow structures; the anteriorly-located ventral cavity and the posteriorly-located dorsal cavity. Both the ventral and dorsal cavities are further subdivided into smaller compartments. Answer and Explanation: The ventral cavity cont...
The dorsal cavity is then further divided into the cranial and spinal cavities, and the ventral cavity is further divided into the thoracic, abdominal and pelvic cavities. Answer and Explanation: Blood in the pleural cavity: f) Hemothorax The th...
3E-H). Posteriorly, it is confluent with its surroundings. The ventral tritocerebral neuropil (VTN) extends longitudinally along the ventral side of the tritocerebrum (III; Figures2K,3E-H). It is situated directly posterior to the nerve root of the labral nerve (Figures2K,3E-H). Posteriorl...
In Dipnoi, the lungs are paired pouches with alveolate walls that perform the respiratory function (the Australian lungfish has a secondarily unpaired lung). The respiratory surface of the lung is increased by trabeculae that protrude into the lung cavity and give its walls alveolarity. In Cladis...
Lung development is subdivided into three main periods (Table1); the embryonic period, the fetal period and postnatal lung development. Lung organogenesis is part of the embryonal period. While fetal lung development consists in the pseudoglandular, canalicular and saccular stages, postnatal lung deve...
In fishes the heart is basically a simple tube which becomes subdivided into four successive chambers, the sinus venosus, atrium, ventricle, and conus arteriosus. Blood from the body enters the sinus and leaves the conus to go to the gills to be oxygenated. The ventricle supplies the main pum...
A thin, subvertical 'accessory' lamina subdivides this fossa, which extends posteromedially beyond the prezygoparapophyseal lamina, forming a deep, probably pneumatic cavity. This cavity is in turn subdivided by a second, anterodorsally–posteroventrally oriented 'accessory' lamina that is visible...
The muscle complex is subdivided into two populations at the middle point (open arrowhead): anteromedially-located CM precursor and posterolaterally located precursor for CC and HP (CC þ HP) in subsequent stage. The posterior tip of the latter directs towards the primordium of the plagiopata...
