_IN THE CELOMAN BOTH INVERTEBRATED AND VERTEBRATED, THE MOTOR ACTIVITY IS PRODUCED THANKS TO A TRIPLE UNIT CONSTITUTED P0R A SKETCH, A MUSCULATURE AND A NERVOUS SYSTEM WE WILL SEE IN THIS SECTION CASE OF THE INVERTEBRATES PROVIDED OF CELOMA THE PLATELMINTOS AND THE NEMALTEMITOS DISPOSE OF MUSCULATURA IN FORM OF A SUBCUTANEOUS STRATUM AND ITS MOTOR MOVEMENTS ARE REGULATED BY A NERVOUS PLEXUS THIS MUSCLE TUBE, ALONG WITH THE PRESSURE EXERCISED BY THE CELOMA, CONSTITUTES A HYDROSTATIC SKELETON WHICH SUPPORTS THE ANIMAL IN ITS DISPLACEMENTS, AMONG THE ARTICLES THE ANELIDS PRESENT EVANGELIZATIONS OF THE WALL OF THE BODY PARAPODIES OFTEN PROVIDED OF BREASTS QUETAS CONNECTED TO THE MUSCULATURE WHILE THE ARTHROPODS HAVE IN HIS EXOSQUELETO A EFFECTIVE MOTOR ELEMENT, THE CUTICLE PRODUCES ARTICULATED EVACUATIONS AND PROVIDED WITH MUSCLES IN ITS INTERIOR LIMBS THAT ALLOW THE ANIMAL ALL TYPE OF MOVIMETTES, MANY ALSO PRESENT OTHER APLAN ECAGINATIONS ADAS ALAS DOTADDAS OF POWERFUL MUSCULATURE BOTH TYPES ARE CONNECTED TO NERVOUS CENTER OF CONTROL AND AN ORGANIZED BRAIN, ALL THE MOVEMENTS OF DISPLACEMAMINETO HAS PLACE BY DEFECT OF LEVER BETWEEN THE RIGID PORTIONS OF THE EXOSQUELETO AND THE ACTIVATING MUSCLES, MANY MUSCLES ARE SESILES AND THE ONLY MOVEMENTS WHAT THEY DO ARE THE RESPIRATORY AND CAPTURE OF THE FOOD ALTHOUGH THEIR LARGE FREE MOVES ARE ACTIVELY MOVING, OTHERS LIKE SQUIDS HAVE ADOPTED A PROPULSOR SYSTEM THROUGH WATER JETS THAT PROJECT BY STRIKING AGAINST THE MIT, TERRESTRIAL MOLLUSCS LIKE THE SNAILS AND THE BABOUS DISPLACED REPTING ABOUT THE SUBSTRATE THROUGH THE FOOT PROVIDED WITH POWERFUL MUSCLES THE SEA URCHINS ARE MOVING WITH THEIR THORNS AND THE STARS THROUGH THE DIMINUTOS FEET THAT PRESENT IN THE ARMS THE AMBULACRAL SYSTEM THAT ALSO SERVES TO BREATHE ..... ........
