Damage to the medulla oblongata can cause several functions of the body to be thrown off and even death. Because cranial nerves run through this section of the brain injury there can cause several sensory problems. For instance, injury can cause numbness or paralysis of the palate and throat causing drooling and a lack of taste. This numbness can also obviously cause problems with speech. It can also cause gagging, inability to rotate the neck, and acid reflux. Surprisingly if a person suffers from brain damage their body can still function if the medulla oblongata is not damaged. However, damage to the medulla oblongata can cause the need for a breathing machine or other life support equipment. If the medulla oblongata is damaged sometimes the brain and body can recover and no longer need the use of a life support machine, but often the body cannot recover and a person is considered to be brain dead. In this stage, the removal of a life support machine will mean a person’s body will no longer function and that person will die. , The medulla oblongata has many connections to other areas of the brain. The medulla oblongata is the most inferior portion of the brainstem and is about three centimeters long., It is a tube-like bundle of nerve fibres, extending from the medulla oblongata to the lumbar region of the vertebral column and is made of two cell types, neurons and glia, and connective pathways called axons..
The nucleus tractus solitarious in the medulla oblongata receives stimulus from the cerebellum, cerebral cortex, limbic system, and area prostema, which provokes physiological changes resulting in the sensation of nausea, with or without vomiting. 1 Get Help With Your Nursing Essay, During homeostatic regulation of blood pressure if a baroreceptor located in the aortic arch and internal carotid arteries detects a decrease in blood pressure it will send fewer impulses to the controllers, the cardiac centre and the vasomotor centre located in the medulla oblongata of the brain simultaneously., The medulla oblongata in the brain receives these impulses and maintains homeostasis (Perez et al., 2015). When the body’s blood pressure is too high (greater than 120/80mmHg), the baroreceptors reflex increases which activate the parasympathetic stimulations of the heart, which leads to a fall in cardiac output., In an ischemic stroke, blood supply to the brain is decreased leading to dysfunction of an area of the brain, say, unable to speak or swallow if medulla oblongata of the brain is affected (Caplan, 2006). In a hemorrhagic stroke, bleeding from a ruptured vessel can also lead to dysfunction of an area of the brain (Caplan, 2006)., A disturbance in acid-base balance stimulated the respiratory centre in the medulla oblongata resulting in increased respirations to meet increased oxygen demand – TACHYPNOEA (Respiration Rate of over 20 breaths per minute) (Steen 2009) The hypothalumus is stimulated by the widespread blood-borne infection and microorganism invasion ., Medulla oblongata The medulla oblongata is a very interesting part of the brain. This very small section of the brain stem has a very large amount of responsibility in the human body. Studies concerni.
