The relative sizes of the external and internal jugular veins of a fetal pig and a fetal human are relatively the same size. This finding is similar in all mammals.
No, the carotid canal is larger than the jugular foramen in the human skull. The carotid canal transmits the internal carotid artery, while the jugular foramen transmits the internal jugular vein and cranial nerves.
The blood from the face and scalp is drained by the external jugular vein. This vein is responsible for carrying deoxygenated blood back to the heart from the head, face, and neck areas.
The venous blood from the brain is drained by a network of veins called the cerebral venous sinuses. The largest of these sinuses is the superior sagittal sinus, which ultimately drains into the internal jugular veins.
Dural venous sinuses are found between the periosteal and meningeal layers of the dura mater, which is the outermost layer of the meninges surrounding the brain. These sinuses drain blood and cerebrospinal fluid from the brain and ultimately connect to the internal jugular vein.
The deoxygenated blood leaves the brain via the dural sinuses. These are large veinous structures located in the dura mater that connect with the internal jugular vein.

In humans there is one external and one internal jugular vein. The internal jugular vein is much larger (about twice the diameter) of the external jugular. In the cat there are a pair of each vein but the external jugular vein is about twce as large as the internal. (Opposite of humans.)
The external jugular vein can be around 5-20 cm long, varying from person to person. The internal jugular vein is typically longer than the external jugular vein.
jugular veins...internal and external
1) internal jugular 2) external jugular 3) vertebral vein

The internal jugular vein The carotid arteries (common and internal) The vagus nerve
internal jugular!
The internal jugular vein is formed from the sigmoid sinus (after receiving the lesser petrosal sinus) just after passing through the jugular foramen to become the internal jugular vein.
Yes, it is. The external jugular passes over (superficially) to the sternocleidomastoid.
No, the jugular veins drain deoxygenated blood from the head. The internal and external carotid arteries carry blood to the brain.
