If a person hyperextends the vertebral column, a tensile force would be imposed

Question

If a person hyperextends the vertebral column, a tensile force would be imposed on the posterior side of the intervertebral disc, and a compressive force imposed on the anterior side. a. true b. false Which variable is the best representation of how strong one is at a given joint (mechanical strength? a. maximum force generated in the muscle b. maximal torque generated about the joint center c. the amount fast twitch fiber in the muscle that cross the joint d. the distance from the joint center to the tendon insertion About which axis does the forearm rotate when or? frontal b. longitudinal When Austrian Felix Baumgartner performed his crazy sky-dive from 24 miles high, his terminal velocity that he achieved in the stratosphere was much higher than the terminal velocity that resulted once he entered the earth's atmosphere. a. true b. false Increasing the firing rate of one motor unit increases force production because a. more calcium enters each fiber which allows a greater number of cross-bridges to become strongly bound b. more fibers with the motor unit are recruited c. more fast twitch fibers are recruited d. larger fibers within the unit are recruited

Explanation / Answer

13 FALSE in hyperextension injuries produces tensile forces in the anterior spine and compressive or tensile forces applied to the posterior elements.
