from Greek sphenoeides, "wedgelike"
The sphenoid bone is one of the seven bones that articulate to form the orbit. Its shape somewhat resembles that of a butterfly or bat with its wings extended.
It is located on the interior surface of the temporal bone, behind the rough surface of the apex.
It is proximal to the jugular foramen.
Sympathetics to the head also pass through the carotid canal. They have several motor functions: raise the eyelid (superior tarsal muscle), dilate pupil, innervate sweat glands of face and scalp and constricts blood vessels in head.
It is located behind the carotid canal and is formed in front by the petrous portion of the temporal, and behind by the occipital.
It is generally larger on the right than on the left side.
the carotid canal is proximal to the jugular foramen
It is formed by the palatine process of the maxilla and horizontal plate of palatine bone.
It forms a partition between the nasal passages and the mouth. This partition is continued deeper into the mouth by a fleshy extension called the soft palate.
- In sucking the soft palate and posterior superior surface of the tongue occlude the oral cavity from the orapharynx, creating a posterior seal.
- The soft palate prevents the escape of fluid and food up through the nose and with the tongue allows fluid and food to collect in the mouth until swallowed.
The anterior region of the nasal cavity, near the nostrils.
