Synovial fluid

have small gaps that contain synovial fluid. When you crack a joint the pressure of the synovial fluid decreases which releases the gases present in the form of a bubble. When the joints are extended there is an increase in the pressure surrounding the joint which causes the gas bubbles to collapse and create the popping sound you hear. After you have to wait around 20 minutes to crack your knuckles again because the gases have to dissolve back into the synovial fluid. Multiple studies have…

Synovial cysts arising from the intraspinal facet joint can directly cause thecal sac or nerve root compression. They are increasingly cited as a major source of spinal instability and mechanical back pain. In this case, we report a 51-year-old woman who has been treated conservatively for a unilateral synovial cyst for 15 months. She then presented with an acute exacerbation of lower back pain, neurogenic claudication and lower extremity weakness. Her magnetic resonance (MR) studies showed new…

Cartilage is what allows the bones to move more freely against each other. This articular cartilage covers the ends of the femur, top of the tibia and back of the patella, as pictured in Figure 4. It is kept slippery by the synovial fluid that is made by the synovial membrane (Marieb & Hoehn, 2013). The bones move easily since it is smooth and slippery. Finally the menisci are in the middle of the cartilage and those that the shock absorbers. According to the findings of Scuderi and Tria in…

a degenerative joint irregularity process. This disease is a serious long-term clinical syndrome with restricted treatment options and deprived outcomes. There are many subsets of this disease but essentially all of them will lead to “persistent synovial inflammation and associated damage to the articular cartilage and underlying bone.” This autoimmune immune disease affects three times more frequently in women after their forty’s and elderly people, suggesting this could be due to a hormonal…

classified as a type of synovial joint, which is one of the most common and complex joints found in the human body. The knee is a meeting point for the femur, fibula, tibia, and the patella. In order to maintain its flexibility and function, several other ligaments join the knee joint in order to keep the attaching bones in place. The knee is the joint where the femur and the tibia meet; the patella (kneecap) is made of bone and sits in front of the knee. The knee joint is a synovial joint…

Muscles bone and joints As we age so does our bodies, changes in the body is a result of changes muscles bone and joints. Our muscles will weaken, joins will ache and our bones will become brittle. Although this is a natural part of aging, how we treat our bodies now will affect how our body function in the future. Things like having a physically activate lifestyle, not doing a lot of physically activities, how we eat. What we eat will affect how well your body function when you age.…

painful swelling in the joints. Unlike primary or secondary gout, pseudo gout occurs when calcium pyrophosphate crystals form in the synovial fluid or deposit on the cartilage. Even though pseudo gout is more common in older population it should be ruled out in younger patients as well especially with no history of prior gout attacks. This can be done by obtaining synovial fluid with aspiration of the joint (Kennedy-Malone et al., 2014, p. 395).…

As we age, our bodies tend to slow down and produce much less of the gooey liquid known as synovial fluid, which lubricates our joints. Synovial fluid is like a clear and slippery water that is filled with lipids (predominant fat) and proteins, which cushion the cartilage, permitting the joints to move conveniently. As these main fluids shrink, wear on the cartilage increases, causing joint pains, weak spot and inflammation. Joint ache is particularly original and may restrict one from dwelling…

-The Skeletal System 1. Explain how and when bone is remodeled. Include the cells and hormones involved in the process. • Bone remodeling is essentially a lifelong process. The mature bone tissue is removed and replaced the new bone tissue. This promotes healthy bones and can also reshape the bones from injuries like fractures. Osteoblasts secrete new bone tissue while osteoclasts break down the old bone tissues. The body signals the correct amount of growth through parathyroid and growth…

The etiology and pathogenesis of RA are complex and multifaceted. A range of predetermined (genes) and stochastic (random events and environment) factors contribute to susceptibility and pathogenesis.(kelly). The initiation of RA probably begins years before the onset of clinical symptoms. This process involves certain specific genes that can help break tolerance and lead to autoreactivity. It is likely that the earliest phases are marked by repeated activation of innate immunity Cigarette smoke…
