cervical curvature
cervical, thoracic, lumbar, and sacral curvature.
Lordosis an anteriorly convex curvature of the vertebral column; the normal lordoses of the cervical and lumbar regions are secondary curvatures of the vertebral column, acquired postnatally
The cervical curvature is the most superior spinal curvature.
You have the convex anteriorly curve of cervical vertebrae. You have the concave anteriorly curve of thoracic vertebrae. Again you have the convex anteriorly curve of lumber vertebrae. The sacrum goes steep backward from the last lumber vertebra. Here no curve is described probably. So you have lardosis of cervical and lumber vertebrae. You have kyphosis of the thoracic vertebrae.
Secondary
a slight curvature of the spine near the neck
No, the cervical curvature is considered the secondary curvature, the primary curvatures are the thoracic and sacral curvatures. The lumbar curvature is also considered the Secondary Secondary curvature (yes that's two secondarys, as in the second secondary)

In the human the level of cricoid is the 6th cervical vertebra.
