sphenotic sphe·not·ic (sfē-nŏt'ĭk)
Relating to the sphenoid bone and the bony case of the ear.
Dorsal to the exoccipital are the opisthotic and pterotic, and dorsal to the pro-otic is the sphenotic.
On the side behind the posterior angle of the frontal is the sphenotic above the posterior part of the eye.
The pterotic and sphenotic together give rise to a large concave surface by which the hyomandibular articulates with the cranium.
They cover the posterior fontanelles and stretch over from the sphenotic to the lateral ethmoid, forming a roof for the orbit.
