Cervical spine fractures can occur secondary to exaggerated flexion or extension, or because of direct trauma or axial loading. Pathology. The cervical spine is susceptible to injury because it is highly mobile with relatively small vertebral bodies and supports the head which is both heavy and acts as a lever.
The inactive molecule pepsinogen is cleaved in a strongly acidic environment to give off the active enzyme, pepsin. Pepsinogen is produced in the stomach by chief cells.
Another is to convert pepsinogen into pepsin. Pepsinogen is released from chief cells in your stomach wall. HCl, chemically changes pepsinogen into pepsin and is essential because pepsin doesnât function in an environment with a pH greater than 5. Pepsin begins protein digestion by breaking it down into peptide chains.
