-
Spiral ganglia --> cochlear nucleus --> brachium of inferior colliculi---> superior olivary nuclei & inferior colliculus ---> lateral geniculate nucleus ---> MGN ---> auditory cortex
-
Spiral ganglia --> lateral lemniscus---> superior olivary nuclei & inferior colliculus ---> brachium of inferior colliculi ---> MGN ---> auditory cortex
-
Spiral ganglia --> cochlear nucleus --> lateral lemniscus---> superior olivary nuclei & inferior colliculus ---> brachium of inferior colliculi ---> auditory cortex
Correct Answer
A. Spiral ganglia --> cochlear nucleus --> lateral lemniscus---> superior olivary nuclei & inferior colliculus ---> brachium of inferior colliculi ---> MGN ---> auditory cortexExplanation
The correct sequence of auditory information starts with the spiral ganglia, which receive auditory signals from the cochlea. These signals are then transmitted to the cochlear nucleus, where they are processed further. From the cochlear nucleus, the signals travel to the lateral lemniscus, which is a pathway in the brainstem that carries auditory information. The lateral lemniscus then projects to the superior olivary nuclei and inferior colliculus, which are involved in sound localization and processing. The signals continue to the brachium of the inferior colliculi, which is a bundle of nerve fibers that connects the inferior colliculus to other parts of the brain. From there, the signals are relayed to the medial geniculate nucleus (MGN), which acts as a gateway to the auditory cortex, where sound perception occurs.Rate this question:

Correct Answer(s)
A. Abdominal viscera
A. Thoracic visceraExplanation
CN X, also known as the vagus nerve, is responsible for innervating various organs in the body. The abdominal viscera refers to the organs located in the abdominal cavity, such as the stomach, liver, and intestines. The thoracic viscera refers to the organs located in the thoracic cavity, such as the heart and lungs. Therefore, CN X outputs to both the abdominal viscera and thoracic viscera, making them the correct answers.Rate this question:

Correct Answer(s)
A. Thoracic viscera
A. Abdominal visceraExplanation
The dorsal efferent nuclei of the vagus nerve are responsible for carrying motor signals from the brain to various organs. The thoracic viscera and abdominal viscera are both innervated by the vagus nerve, so they are outputs of the dorsal efferent nuclei. The hypothalamus and reticular formation, on the other hand, are not directly innervated by the vagus nerve and therefore are not outputs of the dorsal efferent nuclei.Rate this question:
