Title: is the medulla oblongata part of the reticular formation? Post by: DennisO on May 17, 2014 My textbook states that the medulla oblongata is a portion of the brain stem that helps to regulate cardiovascular and respiratory functions including heart rate, respiration rate, and homeostatic activities (like the pH of the blood).
It also states that the reticular formation is a diffuse network of neurons found throughout the brain stem that oversees respiration and circulation and helps to separate important signals to the brain from unimportant signals (hence why we can block out certain odors after a while). So... is the medulla oblongata part of the reticular formation? Title: Re: is the medulla oblongata part of the reticular formation? Post by: vanbu on May 17, 2014 Hello,
The reticular formation (an inner core of gray matter found in the midbrain, pons, and medulla oblongata) of the pontine tegmentum contains multiple cell groups that influence motor function. It also contains the nuclei of several cranial nerves. The facial nerve and the two components of the vestibulocochlear nerve, for example, emerge from and enter the brainstem at the junction of the pons, medulla, and cerebellum. |
