The sphenoid bone, from the Greek sphenoeides meaning wedge-shaped, is one of 8 cranial bones – the top portion of the skull that encloses and protects the brain.
One bone leads to another. I draw the ethmoid bone and that study leads into this one. I admire the shape, location, and the symbolic aspects of the sphenoid bone.
When I complete the superior view of the cranial bone and post it, people note its resemblance to a moth and a butterfly. You might also imagine a bat with its wings extended. This makes sense when you consider it is a body paired with – yes – greater and lesser wings and two pterygoid processes that project from below.
This bone sits at the anterior base of the skull, in the very center of the head. It is here where the nerves leave the brain to connect with the spinal column and the lower spine.
Within it you find the sella turcica ( a saddle shape mass) which houses the pituitary gland (that hangs from the base of the brain by a stalk). It helps to form the septum of the nose and the nerves of the eyes pass through it.
… the nerves of the eyes pass through it. As a visual artist I can’t help but take note of this. And it is this detail that might explain why sphenoid bone is known as the gateway into the mind.
Cranial-Sacral therapy recognizes the bone as a keystone of the cranial floor. There is a cranial pulse, a subtle pulsing (and flexing) of this particular bone signifying health – making the wings that much more magical for me. And I can’t help but think of the Caduceus, the medical symbol showing two snakes winding around a winged staff (life-force rising from the base of the spine). Could the winged crown be the wings of the sphenoid?
The sphenoid considered a sacred bone at the top of the spine, equally as powerful as the sacrum at the bottom.
Meditate on the beautiful sphenoid bone – breath deep and fly.
