The t-test and the one-way analysis of variance (ANOVA) are the two most common tests used for this purpose. The t-test is a statistical hypothesis test where the test statistic follows a Studentâs t distribution if the null hypothesis is supported.
Other causes of damage to these nerves include head traumaand tearing of the nerves, smoking, cocaine, or brain tumors impinging on the nerves. Optic Nerve (CN-II): Sensory for vision. Its nerve arise from the ganglion cells of the retina and pass through theoptic foramen (optic canal).agus Nerve (CN-X): Mixed: sensory and motor. Passes through the jugular foramen. It passes through the neck nextto the carotid arteries, after which the two travel together next to the esophagus through thediaphragm into the abdomen.
These nerves all pass through the superior orbital fissure, a foramen in the sphenoid bone at the rear of the eye socket. Cranial nerve 3, the oculomotor nerve, is a motor nerve that controls muscles around the eye, as well as the ability of the pupil to respond to light changes.ranial nerve 6, the abducent nerve, is a motor nerve that allows the eye to move laterally. Cranial Nerve 5, Maxillary Branch. The maxillary branch of the trigeminal nerve, a sensory branch that supplies the upper lip, sinuses and palate, passes through the foramen rotundum, an opening in the middle of the skull.
