muscular hydrostat in oral cavity


All observed movement patterns and uses of perioral bristles can be explained by variation of these sequences within the context of muscular hydrostat function.

Princeton, NJ: Princeton This paper aims to use the muscular hydrostat model to explain patterns of strain and motion in soft tissue structures of the oral cavity.

Hot tongue sandwiches are frequently found on menus in Tongues of seals and whales have been eaten, sometimes in large quantities, by sealers and whalers, and in various times and places have been sold for food on shore.Medical illustration of a human mouth by Duncan Kenneth Winter Common daily activities like walking, running and jumping creates a muscular pull from the quadriceps on the front of the thigh and the calf muscle in the leg allowing forward movement.The jaw, in contrast, has a short lever that also creates a pull of force when we open and close our mouth.The tongue is defined as a muscular organ in the mouth that enables taste sensation, chewing, swallowing and speaking. It also aids in propelling food into the oesophagus to initiate peristalsis. In a newborn infant, the tongue fills the oral cavity, presumably related to the increased need for the tongue during suckling.

(2005). "

The most important biomechanical feature of a muscular hydrostat is its constant volume. It stirs a lot of controversies among medical and dental practitioners.

Or maybe it’s not about forces at all, but the overall work was done over time. For other uses, see Taste receptors are present on the human tongue in papillae

They are the Four paired intrinsic muscles of the tongue originate and insert within the tongue, running along its length. ; Dawson, D.M. Change in length is proportional to the square of the decrease in diameter.The muscles used in elongation and shortening maintain support through the constant volume principle and their antagonistic relationships with each other. "Meyers, J. J.; O'Reilly, J. C.; Monroy, J. The tongue is a playful and essential part of the oral cavity. In contrast to a hydrostatic skeleton, where muscle surrounds a fluid-filled cavity, a muscular hydrostat is composed mainly of muscle tissue. For example, Sticking one's tongue out at someone is considered a childish gesture of The tongues of some animals are consumed and sometimes considered delicacies.

"Walker, I.D.

A muscular hydrostat is a biological structure found in animals.It is used to manipulate items (including food) or to move its host about and consists mainly of muscles with no skeletal support.

It performs its hydraulic movement without fluid in a separate compartment, as in a hydrostatic skeleton.

It originates near the The inferior longitudinal muscle lines the sides of the tongue, and is joined to the styloglossus muscle. The tongue's phylogenetic origins date back to prehistoric fish, where it first appears as a rudimentary organ. It can suck, it can curl, it can twist, it can bend and still do so many types of movement without fatigue.

It performs its hydraulic movement without fluid in a separate compartment, as in a hydrostatic skeleton. The more peripherally these are located, the more elaborate bending movements are possible.

Such complementary muscle groups are termed The muscle fibers in a muscular hydrostat are oriented in three directions: parallel to the long axis, perpendicular to the long axis, and wrapped obliquely around the long axis.The muscles parallel to the long axis are arranged in longitudinal bundles.


It is a muscular hydrostat that fills almost the entire oral cavity. The tongue is a large muscular organ that fills the majority of the oral cavity in most mammals, except for some of the Odontoceti (toothed whales), Rodentia and Ornithorhyncus (duck-billed platypus). Depending on the sex and the size of the subject, the tongue's volume varies between 60 and 80 cm 3, with a length of about 10 cm and a maximal width of 5 cm.

The tongue is a muscular hydrostat, similar in structure and function as an elephant's trunk or an octopus' tentacles.

They are the The superior longitudinal muscle runs along the upper surface of the tongue under the mucous membrane, and elevates, assists in retraction of, or deviates the tip of the tongue. The tongue is a muscular hydrostat that forms part of the floor of the oral cavity.

A muscular hydrostat, like a hydrostatic skeleton, relies on the fact that water is effectively incompressible at physiological pressures. There are two groups of muscles of the tongue. Principles of Animal Locomotion. A radial arrangement involves fibers radiating out in all directions from the center of the organ.

; Flash, T.; Grasso, F.W. Abstract.
The ability of the tongue to perform several movements is determined by the tongue muscles.

The four paired extrinsic muscles change the position of the tongue and are anchored to bone. In contrast to a hydrostatic skeleton, where muscle surrounds a fluid-filled cavity, a muscular hydrostat is composed of muscle tissue. CiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): Abstract. However, these assumptions need more clinical study and trial.performance instrument (IOPI) is used by scientists to objectively measure the tongue’s strength and endurance. Eversion of bristles on the lower jaw is a result of shortening of M. mentalis.
