Excessive aggressive, sadness, or jealousy is linked to the medulla oblongata. Acetylcholine is used in the motor division and cross over in the medulla oblongata. It is involved in muscle movement, autonomic body functions, and excitatory reactions. Many diseases and disorders affect the medulla oblongata.

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.

2020年2月11日 · 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. …

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).

This results in cellular hypoxia, generating anaerobic metabolism and increased oxygen demand. 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)

2020年9月24日 · It may include renal pelvis and medullary tissue. Both kidneys may be infected. The infection spreads, causing the kidney pelvis and calyces to fill with purulent exudate and cause the medulla to inflame. Abscesses and necrosis form in the medulla and may extend through the cortex to the surface of the capsule.
