Exam 2: Multiple Sclerosis Flashcards
MS definition
- Multiple - multiple areas of lost myelin (from myelin sheath, which wraps around the axon)
- Scleorosis - scarring
Autoimmune inflammatory disease affecting CNS
- Imapairs nerve abiity to send electrical impuse
- Inflammation and immune activity ( T and B lymphocytes, macrophages, destructie cytokines, Ab, and complement) → demyelination of axon
MS associated factors
- Vit D deficiency
- Smoking increases risk
- Infectious factors (measles, canine distemper, herpes, epstein-barr, an chlamydia can trigger
- Not being pregnant, somehow MS is less bitchy if youre pregnant
