I think it is more helpful to assist a person in doing their work than to just answer the question for them. For example: I provided hints that should have led the person to the correct answer. It is a diservice to the person seeking help, to just give them the answer. They will learn more by taking hints provided by us, and using this info as a tool to guide them. If your intent is to demonstrate your vast knowledge, then perhaps you may consider writing an article and posting it in the article section. I am not a mod, so what I say really has little significance, but this is my opinion.
I think it is admirable that you feel that way, and if it make you feel any better, I found the skeletal system to be one of the most hardest to learn in anatomy class. With that said, you are getting through the roughest part.
Best of luck.
i'll give some background info - you don't normally get the basic important information explained clearly from anatomy textbooks.
the main importance of the sphenoid bone that the pituitary gland lies over the sphenoid bone.
the other important things are the holes in the base of the skull is important.
the spheniod bone contains:
1) the internal carotid canal - containing the the major artery that supplies blood to the brain
2) three foramen - foramen ovale, foramen spinosum and foramen rotundem containing the artery that supplies the skull (middle meningeal artery) and two branches of the trigeminal nerve (nerve that innervates the face).
3) the optic canal and superior orbital fissure. the cranial nerves that move the eye muscles (abducent, occulomotor and trochlear nerves), the nerve that supplies the eye (optic nerve) and the blood vessels to the eye (opthalmic artery - branch of internal carotid artery) travel through these.
the ethmoid bone forms the part of the eye socket and parts of the nose.
it also forms a small part of the cranial base as it forms the top bones of the nose.
if you stuck two penils up your nose and wacked them on the table you would have to crush the relatively weak ethmoid bone full of holes before they enter your brain.
the reason for the holes in the bone is that the olfactory nerve travels through holes in the ethmoid bone and is responsible for smell.
the ethrmoid bone also contains the crista galli - a protrusion of the bone that connects to the falx cerebri (the portion of dura matter that separates the two hemispheres of the brain.
hope that clarifies things.
Wow this helped a lot to memorize the anatomy classes and remind me also whenever u see a cadever and the skull bones with out any fleshy parts u mainly found the cribriform plate of ethmoid bone totally damaged ...
Hope u all the best
The person asked the answer to the question, not how to figure it out for him/herself. If someone asks a question, expect it to be answered. While ultimately the person may have found it helpful to give him/her a clue rather than the actual answer, the person did not ask for a clue, he/she asked for the answer. I found the comment to the person who gave the anwer to be rather rude.
Because the policy on this forum is that we do not do someone else's homework. But giving a clue as MichaelXY did will help the poster find the answer by itself. And this policy is a bit older than your membership, so I suggest you learn to live with it.
