Module 06 Case Study: Articulations and Nerve Tissue
Part I— “Jill” Questions
1. What is the difference between a tendon and ligament? (1 point)
--The difference between a tendon and a ligament is that a tendon attaches to muscle. (ie. muscle-bone, muscle-muscle, muscle- skin) A ligament, however, attaches to cartilage. (ie. cartilage-bone, cartilage-cartilage, bone-bone)
2. What bones form the articulation (joint) of the ankle? Did Jill most likely sprain or strain her ankle? Explain your reasoning and the difference between the two? (1 point)
--There are 3 joints that form the ankle, they include the talocrural joint, the subtalar joint, and the Inferior tibiofibular joint. Jill most likely sprained her ankle. I feel this is the …show more content…
What are the four major ligaments of the knee along with their individual function in respect to the femur? (1 point)
--The 4 ligaments of the knee are the ACL, LCL, MCL, and PCL. The Anterior cruciate ligament is located in the center of the knee. This ligament controls rotation and forward movement. Lateral collateral ligament is located on the outside side of the knee, giving stability to the outer knee. Medial collateral ligament is located on the inside of the knee, giving stability to the inner knee. Posterior cruciate ligament is located in the center of the knee, and controls backward movement of the tibia.
4. If you were the trainer that initially saw Jill after her fall, describe what her knee probable looked at (Hint-inflammation). Why did the trainers put ice on her knee right away? (1 …show more content…
What happens to the myelin in Multiple Sclerosis? (1 point)
--Multiple Sclerosis is causes the demyelination of axons in the spinal cord and brain. This is a result of loss of oligodendrocytes and scarring of white matter in the nervous system. Also, demyelination in MS is inflammation caused by an autoimmune response. The inflammation prevents proper recovery and repair of axonal myelination.
10. How does an MRI and spinal tap help confirm the diagnosis of Multiple Sclerosis? (1 point)
-- An MRI helps confirm the diagnosis of MS because it examines the cerebrospinal fluid detecting any abnormalities. A spinal tap shows inflammation in the deep parts of the brain and/or spinal cord. However, it is not 100% accurate in diagnosing a doctor has to perform other test to confirm the findings.
11. Why would steroids help alleviate Kathy’s symptoms? (1 point)
--Kathy was given a steroid because it can help ease pain of inflammation and help slow the disease. It won’t attack the myelin sheath as fast because it suppressing the immune system, therefore lessoning her symptoms.
12. Why did Kathy experience the altered sensation in her lower body? Was there something wrong with her skin? Why couldn’t she stand? Was there something wrong with the muscles of her right leg? (2
