Accessory lungs are one of the most common anomalies and consist of distinctively lobulated masses of incompletely differentiated pulmonary tissue present in the thorax, abdominal cavity, or subcutaneous tissue virtually anywhere in the trunk. Large accessory lungs can cause dystocia. Ciliary dyskinesia (...
Also referred to as theperineumPerineumThe body region lying between the genital area and the anus on the surface of the trunk, and to the shallow compartment lying deep to this area that is inferior to the pelvic diaphragm. The surface area is between the vulva and the anus in the female...
The right common carotid artery arises from the brachiocephalic trunk at the level of the right sternoclavicular joint; thus, it has only cervical parts. Once in the neck, the right and left common carotid arteries have a similar course. They ascend in the neck to the level of the third ...
Thus, the phylogenetic analysis of these character–states supports the view that lamnoids are the sister–group of advanced carcharhinoids (carcharhinids and sphyrnids), sharing the dorsoventral coronary trunk pattern as a synapomorphy.R. Muñoz-Chápuli...
The venous trunk responsible for draining blood from the scalene muscles is the brachiocephalic venous trunk. The latter derives from a branch known as the vertebral vein. In the region of the cervical tract, there are about 300 lymphatic nodes. Those responsible for draining the lymph from the...
4. The Valves Are Like Doors to the Chambers of the Heart Four valves regulate and support the flow of blood through and out of the heart. The blood can only flow one way—like a car that must always be kept in drive. Each valve is formed by a group of folds, or cusps, that ope...
the trunk ribs are immobile and extend dorsolaterally into the dermis, where they are covered by dermal bone to form composite elements (costals). By contrast, the ventral portion of the bony shell (plastron) forms without any endoskeletal contribution but its origin has remained an open questi...
Transverse processes (TVP): A typical feature of most vertebrae in the spinal column; these project laterally with one on each side. In the cervical spine, the transverse processes are unique due to the presence of the foramen transversarium or transverse foramen. Within these foramen, or holes...

from the ethmoid bone, receive their blood supply from the sphenopalatine artery and ethmoidal arteries. In particular, the base of the sphenopalatine artery supplies blood to the middle turbinate. When resecting this turbinate, caution is necessary to maintain the integrity of the main trunk. ...
