Question

Scenario: The above picture illustrates a whiplash injury. As shown in the abuse picture, the impact causes John's neck to be forced into hyperextension. As John's head is forced into hyperextension. what type of force is being exerted on his anterior neck musculature (scalene and sternocleidomastoid)? Tensile Compressive Shear Torsion None of the above What type of contraction are John's anterior neck muscles performing to help slow. down the forced neck hyperextension? Isometric Concentric Eccentric Isokinetic The ultimate tensile strength of a tendon is HIGHER when the tensile load is applied ___to the tendon's fibers. Parallel Perpendicular None of the above (the tensile strength is the same)

Explanation / Answer

6Ans:

In the whiplash injury compression force is affected at neck , it causes the formation of an abnormal S-shaped curve to form.

So the answer is b. Compressive force

7 Ans:

Neck muscle damage takes place coming from eccentric contractions.

So the answer is C. Eccentric

8.Ans:

The tensile load is applied parallel to the tendons fibers , it shows tensile strength of a tendon is higher.

So the answer is a. parallel
