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.
The optic nerve, cranial nerve II, transmits visual information to occipital cortex. The nerve is easily found by locating a large X-shaped structure just caudal to the olfactory bulbs. The fibers anterior to the intersection of the X, are optic nerve fibers. Axons caudal to the intersection, called the optic chiasm, are optic tract fibers. Take time now to consider these facts:
