Answer:
Muscle contraction is the activation of tension-generating sites within muscle fibers. In physiology, muscle contraction does not necessarily mean muscle shortening because muscle tension can be produced without changes in muscle length, such as by holding a heavy book or a dumbbell at the same position. The termination of muscle contraction is followed by muscle relaxation, which is a return of the muscle fibers to their low tension-generating state.

Answer:
C. Acute Epiglottitis
Explanation:
Before explaining why C is the correct answer, let's look at why the others are <u>not</u> correct:
- A. GABHS is a bacterial infection that is a type of streptococcus (aka Strep). It is also the most common cause of Tonsillitis! Symptoms of GABHS typically include: Sore Throat, fever, swollen lymph nodes, and tonsillar exudates. It sounds very like what we're looking for, but notice drooling isn't a symptom found with this one!
- B. Acute Tracheitis is inflammation of the trachea often resulting from a bacterial infection. Symptoms of this condition are more breathing-related such as severe dry cough, wheezing, and even shortness of breath and cyanosis. Not what we're looking at.
- D. Acute Laryngotracheobronchitis is a common disease found in young children that is more commonly known as Croup. This disease is most often characterized by a "barking cough." Other symptoms include fever, stridor and hoarseness.
Now, WHY is C the correct answer?:
Acute Epiglottitis is, like croup, commonly found in younger children and is defined as inflammation of the epiglottis (the flap that covers the trachea when swallowing). It is often characterized by fever, sore throat, difficulty swallowing, and (more specifically) drooling! The drooling coupled with the clear bilateral breath sounds and absence of a cough help to diagnose this illness.

The plural of digitus is <em>Digiti</em>

Dangerous conditions influencing sport injuries include all answers which you've mentioned (overuse, overexertion, and incorrect technique). It doesn't, however, include practicing and drills - d.
Practicing and drills is the thing which would help us become more profficient at a certain task and eventually sport through it.
In sardine fishing, the net is typically laid around the shoal and tightened like a bag. The net is then retrieved slowly to the side of the vessel and the fish are brought aboard. In the case of the Marazion deaths, the vessels involved will be relatively small and have limited storage space so keeping everything balanced is crucial. If by sheer bad luck the net encircled a shoal of fish that was larger than the skipper realised, the boat is immediately put in a dangerous situation. A large catch on one side of the vessel will create an imbalance that will make it much more prone to capsizing when in rough seas. A fisherman died off the coast of nearby Devon in 2012 when his heavily-laden trawler capsized in similar circumstances.
Therefore if the catch is physically too large to retrieve, the vessel would have no choice other than to release the bottom of the net so that the catch falls away.
So surely the fish will swim off? Sadly not in this case. Many midwater species like sardines and mackerel are quite delicate and vulnerable to damage due to the high number of fish caught in the net. In this instance the sardines would most likely likely have been incapacitated as a result of being hauled to the side of the vessel, and when released from the net they would have been washed ashore with the action of tide and waves.
