Exclusively breastfed babies do not require additional water even when it is very hot outside, as long as baby is allowed to nurse as needed. Even in extremely hot, dry weather your baby can get all the liquids needed via breastmilk.
Smooth muscles contract very slowly, whereas skeletal muscles can contract at different rates. Skeletal muscles can be composed of fast-contracting fibers, slow-contracting fibers or a mixture of both.
Cardiac muscles and skeletal muscles are also different in their shape. While the cardiac muscles are semi-spindle, the skeletal muscles are cylindrical in shape. Another difference is that the cardiac muscles are short in comparison to skeletal muscles.The skeletal muscles are attached to the bone through tendons. The skeletal muscles also contain myoblasts, which form the fibers in the muscles. The cardiac muscles are seen in the myocardium of the heart.hen looking at the T-tubules, the skeletal muscles contain more of it than the cardiac muscles. Moreover, the T-tubules in cardiac muscles are also wider. Summary. 1. Cardiac muscles are involuntarily controlled, whereas the somatic nervous system controls the movement of the skeletal muscles.
