Uncinate process
The uncinate process of the cervical spine is a hook-shaped process found bilaterally on the superolateral margin of the cervical vertebral bodies of C3-C7.
The uncinate processes are more anteriorly positioned in the upper cervical spine and more posteriorly location in the lower cervical spine.

The foramen singulare, also known as the singular foramen, is a small opening at the posteroinferior aspect of the fundus of the internal auditory canal (IAC)
It carries the singular or posterior ampullary nerve, a branch of the inferior vestibular nerve which carries afferent information from the posterior semicircular canal
