consists of many structures. We distinguish between the central- and the peripheral nervous system. The two major subdivisions of the central nervous system are the brain and the spinal cord‚ which is found in the spinal column. The peripheral nervous system consists of the nerves outside the brain and the spinal cord. The spinal cord communicates with all the sense organs and muscles except those of the head. It is compromised of grey matter which is densely packed with cell bodies and dendrites and white

ascending pathway which projects to the Thalamus in the brain. Sensations of pain are controlled by the ascending and descending pathways in the central nervous system. The feelings of pain are conducted through the peripheral nerves‚ through the spinal cord and the brain stem and finally into the brain itself. The Descending pathway The descending pathway is triggered during pain. The is an example of

The sensory receptors in the integumentary system communicate with the brain and spinal cord via the nerves (the three parts of the nervous system). 6.

Percutaneous Nephrostomy Percutaneous nephrostomy‚ or nephropyelostomy‚ is an interventional procedure that is used mainly in the decompression of the renal collecting system. percutaneous nephrostomy catheter placement has been the primary option for the temporary drainage of an obstructed collecting system. With proper training‚ technical success is achieved in more than 95% of cases. Diagnostic imaging often demonstrates the level and cause of obstruction; however‚ at the time of tube placement
