If you were to do a horizontal section of skull and look down into the cavity you would see a base made up of three levels. This is where the cerebrum sits and is called the cranial floor.
The sphenoid bone spans the width of the cranial floor. It is a butterfly-shaped bone located at the base of the skull, and it articulates with many other bones, forming part of the floor of the cranium.
Sphenoid bone: A prominent, irregular, wedge-shaped bone at the base of the skull. The sphenoid bone has been called the "keystone" of the cranial floor since it is in contact with all of the other cranial bones.The Greek physician Galen wrote that the sphenoid bone was "like a wedge thrust between the skull and the superior maxilla."
Where one cranial bone meets another is referred to as a suture line.
The Sphenoid (Sphenoidal Bone) this is why it is know as the keystone of the cranial floor *The sphenoid is not a facial bone, it is a cranial bone. There is no facial bone which 'articulates' with 'every other facial bone'. Articulation suggests jointed so sutures would make more sense & these sutures would be on all facial bones edges which knit them together
The Olfactory nerve. CN1 Cranial Nerve I, or the first cranial nerve called the Olfactory nerve.
The sphenoid bone spans the width of the cranial floor. It is a butterfly-shaped bone located at the base of the skull, and it articulates with many other bones, forming part of the floor of the cranium.
It is a sphenoid bone; single, irregular bat(a bird)-shape bone forming part of the CRANIAL Floor. Not many people think sphenoid bone being part of the cranial bone that is why they don't find any answer to this question. but Sphenoid bone is one of the cranial bone and can be found on the cranial floor when looking at the skull from its superior view.
The pituitary gland sits in the hypophyseal fossa, which is a bony depression on the cranial floor at the base of the brain. It is located in the sphenoid bone, specifically in the sella turcica region.
The cranial nerve responsible for moving the cheek muscles is cranial nerve V (the trigeminal nerve). However, cranial nerve IX (glossopharyngeal) and cranial nerve XII (hypoglossal) are also involved in moving the tongue, the throat for swallowing and the muscles along the floor of the jaw.

The brain lies within the cranial cavity which is inside the larger dorsal cavity
How many cranial nerves are there
Cranial Nerves 1-2 Cranial Nerves 3-4 belong to the midbrain. Cranial Nerves 5-8 belong to the pons. Cranial Nerves 9-12 belong to the hindbrain.
cranial nerve I: olfactory:smell cranial nerve II:optic:vision cranial nerve III: oculomotor: 4 of 6 eye muscles cranial nerve IV: trochlear: cranial nerve V: Trigeminal cranial nerve VI: Abducens cranial nerve VII: Facial cranial nerve VIII: Vestibulochlear: hearing cranial nerve IX: Grosspharnxgeal: saliva formation cranial nerve X: Vegus cranial nerve XI: Acessory Spinal: trapizious movement cranial nerve XII: Hypoglosseal: toungue movement
