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.
The pancreas secretes zymogens partly to prevent the enzymes from digesting proteins in the cells in which they are synthesised. Enzymes like pepsin are created in the form of pepsinogen, an inactive zymogen.Pepsinogen is activated when chief cells release it into HCl which partially activates it.he pancreas secretes zymogens partly to prevent the enzymes from digesting proteins in the cells in which they are synthesised.
