While the t-test is used to compare the means between two groups, ANOVA is used to compare means between 3 or more groups. There are several varieties of ANOVA, such as one-factor (or one-way) ANOVA, two-factor (or two-way) ANOVA, and so on, and also repeated measures ANOVA.
If you recall, CN VII is responsible for taste sensation in the anterior two-thirds of the tongue. Well, it's the glossopharyngeal nerve, also known as cranial nerve IX, that is the nerve responsible for the sensation of taste in the posterior one-third of the tongue. In addition, cranial nerve IX is a nerve that innervates one of the three major salivary glands, called the parotid gland.
The twelve cranial nerves serve the head and neck. The vagus nerve (cranial nerve X) has autonomic functions in the thoracic and superior abdominal cavities. The special senses are served through the cranial nerves, as well as the general senses of the head and neck.The movement of the eyes, face, tongue, throat, and neck are all under the control of cranial nerves.he olfactory, optic, and vestibulocochlear nerves (cranial nerves I, II, and VIII) are dedicated to four of the special senses: smell, vision, equilibrium, and hearing, respectively. Taste sensation is relayed to the brain stem through fibers of the facial and glossopharyngeal nerves.
