The muscular system consists of skeletal muscles which help move the skeleton and control movement, smooth muscles which are involuntary and control the stomach and intestine, and cardiac muscles which include the heart muscles.NVERTEBRATES & VERTABRATES. MUSCULAR Porifera-has no muscular system and is limited myocyte capability in some pinacocytes and although sponges have cells with specialized functions they do not have tissues. There is no endoderm, mesoderm, or ectoderm.
The somatic nervous system allows us to consciously control our skeletal muscles, and the autonomic nervous system controls activity that humans cannot consciously control, such as the pumping of the heart and the movement of food through the digestive tract.
