Question

Which of the following is critical to the function of most exoskeletons, endoskeletons, and hydrostatic skeletons?
a. Muscles interact with the skeleton in antagonistic groups.
b. Muscles attach to each of these types of skeleton via tendons.
c. Muscles extend joints by pushing skeletal elements.
d. Segments of the body or limbs are extended when paired muscles relax in unison.

Accepted Answer

Hi everyone. Let's look at the next question. It says which of the following makes a movement possible. When we think about movement in the body we recall that involves the musculoskeletal system. We have muscles attached to different points on our bones. The bones have joints and then the contraction and relaxation of the muscles moves the bones around the joints so to make a movement possible, you have to have interaction among the components of the musculoskeletal system. So let's look at our answer choices. Choice A says interaction of different senses in the body. Uh No that's not gonna be enough to cause movement. So not our answer choice B. Says interaction of the nervous and skeletal system. Um That's leaving out the muscles with which you're not without which you're not going to have movement. So that wouldn't be a complete answer there. Choice C interaction of muscles and bones and yes, those are the components of the muscular skeletal system. That's what makes movement possible. Is that interaction of muscle and bone And finally Choice. D. Says interaction of brain and heart. Well that may be great but that's not going to move cause movement. So that's not our answer here. So again, pretty straightforward here. Which of the following makes a movement possible. Choice C interaction of muscles and bones. See you in the next video
