The foramen magnum is a very important feature in bipedal mammals. One of the attributes of a biped's foramen magnum is a forward shift of the anterior border of the cerebellar tentorium; this is caused by the shortening of the cranial base. Studies on the foramen magnum position have shown a connection to the functional influences of both ...
The foramen magnum is located inferiorly under the skull, which puts much of the weight of the head behind the spine. The flat human face helps to maintain balance on the occipital condyles . Because of this, the erect position of the head is possible without the prominent supraorbital ridges and the strong muscular attachments found in, for ...
The forehead of the chimpanzee receded to form a heavy browridge and a jutting jaw; the Taung Child's forehead recedes but leaves no browridge. Its foramen magnum, a void in the cranium, where the spinal cord is continuous with the brain, is beneath the cranium so the creature must have stood upright. [33] This is an indication of bipedal ...
The skull was an indicator of orthograde posture because of the location and orientation of the foramen magnum. The foramen magnum is the space in the skull that acts as the bridge to the central nervous system from the spinal cord to the brain. For animals with "pronograde posture, the foramen magnum is dorsally oriented, whereas in humans it ...
The foramen magnum (Latin: large hole) is a large oval foramen longest front to back; it is wider behind than in front where it is encroached upon by the occipital condyles. The clivus, a smooth bony section, travels upwards on the front surface of the foramen, and the median internal occipital crest travels behind it. [3]

The occipital sinus commences around the margin of the foramen magnum [2] by several small venous channels (one of which joins the terminal part of the sigmoid sinus). It terminates by draining into the confluence of the sinuses .
The formed nerve enters the skull through the foramen magnum, the large opening at the skull's base. [1] The nerve travels along the inner wall of the skull towards the jugular foramen. [1] Leaving the skull, the nerve travels through the jugular foramen with the glossopharyngeal and vagus nerves. [8]
