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.
Information concerning olfaction goes directly to the cerebrum in the olfactory tract. This is the only cranial nerve whose sensory information goes directly to the cerebrum rather than being relayed by the thalamus. The optic nerve is a special sensory cranial nerve that carries visual information. The ganglion cells of the retina have axons that pass through the optic nerves.
