Hydrostatic skeleton

hydrostatic skeleton Fluid-?lled closed chambers that give support and shape to the body in organisms such as jelly?sh and earthworms. No to be confused with the water-vascular system of echinoderms.
hypertension High blood pressure; blood pressure consistently above 140/90.

hydrostatic skeleton
A skeletal system composed of fluid held under pressure in a closed body compartment; the main skeleton of most cnidarians, flatworms, nematodes, and annelids.

hydrostatic skeleton a water-based skeleton present in many animals (such as the earthworm) that lack structures, such as bone, for muscles to pull against.
hypothalamus the portion of the forebrain that serves as the control center for hunger, thirst, body temperature, and blood pressure.

hydrostatic skeleton . A mass of fluid or plastic parenchyma enclosed within a muscular wall to provide the support necessary for antagonistic muscle action; for example, parenchyma in acoelomates and perivisceral fluids in pseudocoelomates serve as hydrostatic skeletons.

A hydroskeleton, also called hydrostatic skeleton, occurs in many soft-bodied animals, such as earthworms. A hydroskeleton is not bony, but rather is a cavity filled by pressurized fluid.

The noncompressible fluid of the body cavity can function as a hydrostatic skeleton against which muscles can work.
The presence of a cavity enables the internal organs to grow and move independently of the outer body wall.

Locomotion is generally brought about by a system of muscles in conjugation with a skeleton. The skeleton may be an endoskeleton, an exoskeleton or a hydrostatic skeleton. The support system will be adapted to methods of locomotion for a particular animal (e.

Our own skeleton so whether you’re insect and you wear your skeleton on the outside or you’re jelly fish and you use water that’s on the inside of you as a hydrostatic skeleton.
