A Spill at Parsenn Bowl:
* What mechanisms did Elaine’s body employ to maintain homeostasis?
In the extreme cold, Elaine’s cutaneous blood vessels would constrict, helping retaining heat. Elaine would also begin shivering as the body attempts to accumulate additional body temperature.
* What are the sensors for cold?
Thermoreceptors in the skin.
* Where is the “thermostat” of the body located?
Hypothalamus.
* What is the effector (i.e., what tissues are involved) for the blood vessel constriction? For the shivering?
Blood vessel constriction results from contraction of vascular smooth muscle. Shivering results from the contraction of the skeletal muscles, which produces heat.
* What areas of the body would be most vulnerable to frostbite?
Distal extremities and exposed tissues.
* Why was Elaine instructed to remove her parka?
Elaine’s Parka was wet from the conditions outside and once indoors the evaporation of the moisture would further heat loss.
* Why was she shivering?
Shivering is reflex triggered by early Hypothermia.
* Why was the Knee swollen?
Inflammation of the knee was caused by leaking fluids from torn tissues.
* Where would the dorsalis pedis pulse be taken? Why?
The Dorsalis Pedis pulse would be take at the foot to check for circulatory response. If the pulse is absent it would be wise to check a proximal area to see where the affected area could be.
* How do the bones that compromise the knee joint fit together?
The lateral meniscus articulates both lateral condyle of the femur and the lateral condyle of the tibia and the medial meniscus articulates both the medial condyle of the femur and the medial condyle of the tibia. Lastly the patellar is found in the quadriceps tendon ligament.
* What Structures are associated with the medial surface of the knee?
The medial collateral ligament and the medial meniscus.
* What type of injuries would be identifies most...
