This means that I have a Master's Degree in Social Work and have completed the necessary requirements to be fully licensed in the state of Michigan. Licensing requirements include completing 4,000 post-Master's level work hours under the supervision of an LMSW and passing the licensing exam in social work. The focus of my work is clinical, so I completed the licensing requirements in the area of clinical social work.
the section of the brain which contains the centres for cardiac, respiratory and vasomotor action is the medulla oblongata.
The respiratory center (RC) is located in the medulla oblongata and pons, which are part of the brain stem. The RC receives controlling signals of neural, chemical and hormonal nature and controls the rate and depth of respiratory movements of the diaphragm and other respiratory muscles. Injury to this center may lead to center respiratory failure, which necessitates mechanical ventilation; usually the prognosis is grave. In healthy individuals the presence of elevated carbon dioxide levels in the blood is the stimulant that the RC responds to in order to signal the respiratory muscles to breathe. Chemoreceptors found in carotid bodies and aortic bodies are responsible for detecting decrease in blood pH by this carbon dioxide.
