Summary Introduction
To review:
The treatment leech therapy or an anti-inflammatory drug diclofenac that had the greater effect in reducing the pain of arthritis patients. The leech therapy has a prolonged effect or not, need to be discussed here.
Introduction:
Osteoarthritis is also called degenerative joint disease, which has the most common prolonged effect on the joints. The breakdown of cartilage between joints leads to an unbearable pain, stiffness, and swelling. The treatment of this disease is leeches therapy and an anti-inflammatory drug called diclofenac.

Tetanus is a disease caused by Clostridium tetani characterized by muscle spasms. Just like the toxin produced by Clostridium botulinum, this toxin produced by C. tetani interferes with muscle contractions. Where botulina toxin causes paralysis, C. tetani toxin causes muscle spasms and painful contractions lasting minutes at a time. Additional symptoms include stiffness and rigidity of muscles. Using your knowledge of how muscles contract explain what steps within a muscle contraction are being interfered with to cause these symptoms?
How is it that a mutation in the Ptx1 can allow it to stop being active in the pelvic area, but not in the other tissues of stickleback fish?
Group of answer choices
A- The mutation is in the GENETIC SWITCH that turns ON/OFF the genes that lead to PRESENCE/ABSENCE only of pelvic fins.
B- The mutation is in the GENE that makes the materials that build only the pelvic fins.
A 19-year-old male patient is admitted with a fracture of C6 and C7 that has progressed to quadriplegia. His career as a football player had been very promising. He was injured during a football game at the university where he is currently a senior. At the time of the injury, contract negotiations were in progress with a leading professional football team.
2.Consider what adaptations would be necessary in each of the following four adaptive modes: (1) physiological, (2) self-concept, (3) interdependence, and (4) role function.

How do they do this? a. Their bones are filled with water, which provides the weight of the skeleton. b. The change in body structure is caused by contraction of muscles compressing the watery body fluid. c. The muscles contain water vacuoles, which, when filled, provide a rigid internal structure. d. The term hydrostatic simply refers to moist environment. They generate movement just as arthropods do.arrow_forwardA 23-year-old male patient is admitted with a fracture of C6 and C7 that has resulted in quadriplegia.
