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 CTNcarries taste from the anterior two thirds of the tongue. TheGSPN, which is also a branch of facial nerve, mediates tastefrom the palate. Lingual branches of the glossopharyngealnerve carry taste from posterior third of the tongue.Thefibers from the pharyngeal plexus of the vagus nerve formspecial visceral afferents from the tongue base and epiglottis 2 .Glossopharyngeal nerve is normally inhibited by the CTN inthe taste network.This inhibition is abolished when CTN isdamaged, which can serve as a compensatory mechanism totaste loss.hefibers from the pharyngeal plexus of the vagus nerve formspecial visceral afferents from the tongue base and epiglottis 2 .Glossopharyngeal nerve is normally inhibited by the CTN inthe taste network.
