Grey matter IN the CNS is called nuclei Anything that ends in “ING” is what takes place in the medulla EX: sneezing, coughing, raising the heart They are all things in your body that you can not control The medulla is like the “foreman” of your brain The hypothalamus has input with the medulla Bigger than the hypothalamus is the cortex Which one does not belong? Sneezing, coughing, skeletal muscle motion ? Medullary rhythmicity center is in the medulla oblongata The pons means its bridge; it connects the medulla to the mesencephalon It contains axons that are not myelinated and myelinated Also in the pons there are computers, the two to know are the pontine together and separate they are the apnuestic and pneumotaxic These two work in breathing along with the medullary rhythmicity center These are also responsible for allowing you to breath rhythmically Also in the pons as well as in the medulla is the reticular formation The mesencephalon Two rounded masses and a little round mass and the pineal body The whole thing Is called the corpora quadragemina The big parts are called the superior canaliculus The little ones are called the inferior canaliculus The superior deals with visual reflexes (snapping fingers in someone’s face) The inferior deals with auditory reflexes (loud music in the car) What is the job of the superior canaliculus?
