A: Long-term, untreated leprosy may cause people lose the use of their hands or feet due to repeated injury because they lack feeling in those areas of the body. Ultimately, all forms will cause nerve damage in the arms/hands and legs/feet, causing sensory loss in the skin and muscle weakness. This may cause the person with leprosy to lose an extremity affected by the disease.
B: Schwann cells are involved in many important aspects of peripheral nerve biology. The conduction of nervous impulses along axons, nerve development and regeneration, trophic support for neurons, production of the nerve extracellular matrix, modulation of neuromuscular synaptic activity, and presentation of antigens. The nerve impulses …show more content…
Once the body gets use to something not being present it will act as if it was never there.
J: Yes, not having that leg will set off the sensory nerves and not allow Sannu to stand and have proper equilibrium and sense of balance.
K: Leprosy bacillus can reproduce only at temperatures just a few degrees below core body temperature; CNS leprosy is rare if it exists at all. Leprosy produces a peripheral neuropathy, which is characterized by the involvement of nerves only in the cooler parts of the body. In persons with tuberculoid leprosy, nerve trunks are involved; the nerves situated immediately subcutaneously are affected. In lepromatous leprosy, terminal nerve endings are involved, producing a patchy sensory loss; the cooler areas of the skin (ears, back of the hands) are affected first. Leprosy is rare in the United States, but worldwide it is one of the most important causes of peripheral neuropathy (in the United States, peripheral neuropathy is diabetes mellitus). An invasion of new cases appeared in the U.S. when veterans who contracted the disease in Southeast Asia returned home. I would have to say that in Sannu’s case would have to sensory pathway
