Compare and contrast skeletal, cardiac, and smooth muscle tissue relative to structure, body location, and specific function.

Hi, everyone. Let's look at our next question. The skeletal, cardiac and smooth muscles in the human body can be classified as voluntary and involuntary, which among the following muscles is considered voluntary muscles. Choice, a smooth muscles of the digestive system. B, cardiac muscle, C, triceps, bray I or D reflex muscles. So somewhat, obviously, voluntary muscles are muscles used to make voluntary movements that we have a conscious control over. So that would lead us to skeletal muscles and choice C triceps bra is an example of one of those skeletal muscles in the arm. So that is a voluntary muscle. We know we will only have one correct answer. But it's somewhat obvious when we look at our other answer, choices that they would not be involved in voluntary motion, choice, a smooth muscle of the digestive system. Those are obviously involuntary muscle contractions in the process of digestion. So not our answer. Uh cardiac muscle choice B obviously, we don't control the muscles in our heart and then finally, reflex muscles, these would be muscles behind involuntary reflex movements. So things like um blinking when an object comes at you, blinking can be a voluntary movement but the muscles that control blinking as a reflex would be reflux muscles and then say, are your pupil contracting or dilating when in a darker or lighter environment? So those are not voluntary muscles and therefore, aren't our answer. So again, the example of voluntary muscles in this question, choice C triceps break. See you in the next video.
