Morphology
The phrase is fully compositional: 'seventh' marks the ordinal, 'cranial' specifies location relating to the skull/brain, and 'nerve' names a nerve, so a learner who knows the constituents can infer it is the seventh nerve of the cranial (skull) nerves. Although detailed clinical functions (facial muscle control and taste) are domain-specific facts beyond simple composition, the referential identity of the expression is directly derivable from the parts.
Etymology
Seventh cranial nerve simply says it is the nerve number seven and that cranial means 'of the skull'. It controls the muscles of the face and taste at the front of the tongue, so the name points to its place and job.
