Sannu's Story
Sannu’s Story A. Leprosy, caused by the bacterium Mycrobacterium leprae, is a leading cause of peripheral neuropathy worldwide; although it is treatable, the damaged caused by the disease is irreversible. In Sannu’s case, why is there both sensory loss and muscle weakness?
Sannu contracted leprosy from an unknown source and went untreated due to limited medical care. Because of limited medical care and the lack of treatment the sores that were caused by leprosy started to damage the free nerve endings and soon started to cause muscle weakness because of the infection spreading into the muscles. B. Leprosy can affect the skin and Schwamm cells of peripheral nerves. Which events of sensation processing are most likely not functioning properly in Sannu’s Leporsy?
Sensory neurons send out signals from the peripheral nervous system, so when it is affected by leprosy, the Schwamm cells are not sending the signals out to the sensory imput. C. Were somatic, visceral, or special senses being investigated when Dianna evaluated Sannu’s Achilles and Babinski reflex activity?
No, she was just investigating just his somatic and visceral. D. Sannu has lost sensations of pain, temperature, light touch, and pressure. What types of receptor endings mediate the detections of the sensations?
By losing sensations of pain, temperature, light touch, and pressure, Sannu has lost encapsulated nerve endings that are receptors for pressure and vibration as well as Free nerve endings which are the receptors for pain, temperature, itch, and some touch sensation. Sannu’s Exteroceptors will be affected by this as well because these receptors are sensitive to what is going on outside the body, such as pain, temperature, pressure, touch, and vibration E. Leprosy infects the body via the skin, typically in the cooler regions of the body. Based on this information, would Sannu’s interoceptors be affected?
Yes, because the interoceptors are to monitor the blood vessels,
