Cardiac,skeletal, and smooth muscles have different characteristics and rolesin the body of a human being. Particularly, skeletal muscles aid inmovements, smooth muscles protect the wall of hollow structures whilecardiac muscles help in the maintenance of blood supply. In adifferent perspective, men and women have dissimilar muscle mass dueto their physical orientation and hormones (Sherwood, 2015). Thepaper, therefore, discusses the student’s post on the difference incardiac, skeletal and smooth muscles as well as the disparity betweenmen and women in regards to muscle mass.
Skeletalvs. Smooth vs. Cardiac Muscles
Thestudent focuses on structure, activity, purpose and action of themuscles to determine their difference. In the case of skeletalmuscles, the pupil asserted that they are always striated under amicroscope, and they help in the body movement through thecontraction while their objectives are to overcome fatigue. Accordingto the discussion, it is not scientifically evident that skeletalmuscles are all over the body because they are not present in theinternal organs like intestine. Furthermore, it is true that smoothmuscles are involuntary, and they majorly exist in hollow structures.Lastly, cardiac of muscles are available in the heart and tips ofblood vessels. Concerning the discussion of the learner’s postsmuscles it evident that muscles have different roles and structures(Sherwood, 2015).
Menvs. Women and Muscle Mass
Thelearner argued that the different muscle mass of men and women are asa result of evolution and nature of work within the society. Thediscussion of the student post, dispute the evolution theory as thecause of differences in the muscle mass between men and women.However, a valid explanation for muscle mass dissimilarity in womenand men is due to hormonal disparities. In other words, women have alot of estrogens which increases their fat content while men havetestosterone which helps in muscle build up (Sherwood, 2015).
Itis worth noting that a human being has different muscles which havevaried roles in the system. Moreover, men have more muscle mass thanwomen because of their body structure. It is, therefore, relevant formen to regulate testosterone to ensure the build-up of muscles whilewomen require estrogen as their body is made up of more fat thanmuscles.
