Each sinus is lined by a ciliated pseudostratified epithelium, interspersed with mucus-secreting goblet cells. Each sinus is lined by a ciliated pseudostratified epithelium, interspersed with mucus-secreting goblet cells. The sphenoid bone is an unpaired bone of the neurocranium.It is situated in the middle of the skull towards the front, in front of the basilar part of the occipital bone.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. The inner ear is innervated by the vestibulocochlear nerve (CN VIII).It enters the inner ear via the internal acoustic meatus, where it divides into the vestibular nerve (responsible for balance) and the cochlear nerve (responsible for hearing):. The nerve is responsible for equilibrium and hearing. Pharyngeal Clefts. The skull can be further subdivided into: The disc has a low signal on all MRI sequences, but it may be possible to see intermediate signal centrally in the anterior and posterior bands.

The canal connects the posterior cranial fossa and the inner ear, transporting neurovascular structures to the auditory and vestibular apparatus. fossae) (L.) a trench or channel; in anatomy, a hollow or depressed area. Henneberts sign (i.e., vertigo or nystagmus caused by pushing on the tragus and external auditory meatus of the affected side) indicates the presence of a perilymphatic fistula. The perivertebral space is a cylinder of soft tissue lying posterior to the retropharyngeal space and danger space surrounded by the prevertebral layer of the deep cervical fascia and extends from the skull base to the upper mediastinum.. The opening of the IAM, the porus acusticus internus, is located within the cranial Surfaces External. The vestibulocochlear nerve is located in the internal auditory meatus (internal auditory canal). The head rests on the top part of the vertebral column, with the skull joining at C1 (the first cervical vertebra known as the atlas).The skeletal section of the head and neck forms the top part of the axial skeleton and is made up of the skull, hyoid bone, auditory ossicles, and cervical spine..
