The major anatomical difference between hominids and the apes is that the foramen magnum of hominids islocated at the bottom of the skull.
located at the bottom of the skull
It's at the bottom of the skull. Have fun cheating on the test, I don't judge! :D
The foramen magnum is positioned in the center of the basicranium (the bottom of the skull).This is a change from the foramen magnum being further back as it is in normal quadrupeds such as in apes as the upright spinal shape requires a more central entrance into the skull in order toalso keep the head upright, in the optimum visual position.The location of the foramen magnum also means that the head is better balanced and that the facial muscles are not required to support the skull upright but instead are used purely for facial expressions.
Foramen: Any opening Fossa: A depression, eg. the base of skull that cradles occipital lobe
The foramen in males is large and oval shaped (almost a flattened isoceles triangle). The foramen in females is much more triangular, as well as smaller.
A transverse foramen is located on the transverse process of cervicle vertebra. The vertebral foramen is the large (more anterior) opening in the body of a vertebra through which the "spinal chord" passes. when the vertebra are stacked in the vertebral column, the series of vertebral foramen is called the vertebral canal.
bottom of the skull because early hominids walked upright
You have the foramen between the wall of the atria in case of the fetus. It is called as foramen ovale.
The jugular foramen lies between the occipital bone and the temporal bone.
A fissure can mean a split in the geological structure of the earth or any opening in the body. A foramen is an opening that can connect the bodily systems together. Foramen does not pertain to geological structures but just biological things. See related links below for more information and sources
Foramen ovale is a window between the 2 auricle before birth
There is the hole between two atria in the fetus. That is called as foramen ovale. You have one foramen ovale at the base of the skull. Mandibular nerve passes through this foramen ovale.
When you look on the side of a vertebral column, the intervertebral foramen is an opening that can be found between the two bodies and inferior articular processes of an adjacent, stacked pair of vertebrae. (There is a picture of the intervertebral foramen attached in the related links) A Way to Remember: Inter means between Vertebral means pertaining to the vertebrae Foramen means hole It literally means "hole between the vertebrae!"

The interventricular foramen are referred to as the foramen of Monro
The obturator foramen is the largest foramen in the human body.
