The frontal lobe represents more than a third of the entire human hemisphere and its complete maturation is associated with the acquisition of complex cognitive functions and behaviors characteristic of the adult life. The central role of the frontal lobe in primate evolution is reflected not only ...
Below C6, the artery is located between the scalenus anterior and longus colli muscles and anterior to the sympathetic trunk, vertebral vessels, inferior thyroid artery and subclavian artery. Carotid sheath dissected in a cadaver: Notice the position of the left external carotid artery; the artery...
Theparotid gland (PG)is the largest of the three major salivary glands. It is located between the sternocleidomastoid muscle and the masseter, extending from the mastoid tip to just below the angle of the mandible. A small tail projects from the inferior edge of the gland, separated by...
PerineumPerineumThe 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, and between the scrotu...

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...
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...
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...
