- Making the world better, one answer at a time. Mollusks have reduced coeloms for body cavities. These are made of layers of mesoderm and are used for suspending the mollusk's internal organs.pithelial tissue is one of the four types of tissue in the body (nervous, muscular, and connective being the other three) that lines the body cavities. It is also found in th … e skin, which is the organ that covers most of the body's surface. + 2 others found this useful. Pam Hurston.

- The Alexander Technique is an educational method used worldwide for over 100 years. By teaching how to change faulty postural habits, it enables improved mobility, posture, performance and alertness along with relief of chronic stiffness, tension and stress.nother reason people take lessons in the Alexander Technique is to enhance performance. Athletes, singers, dancers, and musicians use the Technique to improve breathing, vocal production, and speed and accuracy of movement.

BIOLOGICAL DIVERSITY: ANIMALS III The Phylum shares features with other animal phyla. The mollusks are bilaterally symmetrical, have an organ system level of body organization, have a complete digestive system, and a coelom (small in size). Additionally these animals have a circulatory system and a respiratory system.

Physical Therapist's Guide to  Hip Labral Tears Further Reading. Hip labral tears occur when the labrum, a band of cartilage surrounding the hip joint, is injured. Labral injuries can be the result of trauma, such as a fall or a car accident, but are most commonly caused by repetitive trauma to the hip joint.

Characteristics of Mollusks Characteristics of Mollusks. Mollusks are soft-bodied invertebrates with bilateral symmetry and usually one or two shells. Their organs are in a fluid-filled cavity; the word mollusks in Latin means soft. Most of the mollusks live in water but some live on land.

- Snails, oysters, clams, octopuses, and squids are examples of mollusks. • The body cavity in mollusks is a true coelom. – In animals that have a coelom, the gut and other internal organs are suspended from the body wall and are cushioned by the fluid within the coelom. Respiration – Most mollusks respire with gills, which are located in the mantle cavity. The mantle cavity is a space between the mantle and the visceral mass. – Mollusk gills extract 50% or more of the dissolved oxygen from the water that passes over them.

- All mollusks have a muscular foot used for locomotion, as well as a mantle, an outgrowth that covers the animal. Many mollusks have an external calcium carbonate shell, hanging over the mantle, that is actually produced by the mantle. The mantle is also used in respiration, waste disposal, and sensory reception.

- Other gastropod species have developed the ability to breathe air later. All marine gastropods, as well as some fresh water gastropods, breathe with gills. Snails originally possess the so-called comb-gills (ctenidia), which are also located in the pallial cavity.nails' excretion organs originally were derived from the segmented worms' (Annelida) metanephridia. While water snails excrete a very much diluted primary urine, terrestrial pulmonate snails have developed the ability to resorb most of the water.

What is a bivalve mollusk? A roughfile clam from the Flower Garden Bank National Marine Sanctuary—just one of many different bivalve mollusk species. Like fish, bivalve mollusks breathe through their gills. As filter feeders, bivalves gather food through their gills.Some bivalves have a pointed, retractable foot that protrudes from the shell and digs into the surrounding sediment, effectively enabling the creature to move or burrow.Bivalves even make their own shells. roughfile clam from the Flower Garden Bank National Marine Sanctuary—just one of many different bivalve mollusk species.

Body cavity A body cavity is any fluid-filled space in a multicellular organism other than those of vessels (such as blood vessels and lymph vessels).he term usually refers to the space located between an animal ’s outer covering (epidermis), and the outer lining of the gut cavity, where internal organs develop. ‹The template Elucidate is being considered for deletion.›.

What type of body cavity do mollusks have? Mollusks have reduced coeloms for body cavities. These are made of  layers of mesoderm and are used for suspending the mollusk's  internal organs.he basic body structure, consisting of a foot, visceral mass, and mantle, is similar in most mollusks. The foot is located below the visceral mass.

- Mollusks usually have a shell (although some do not). Mollusks also have an extension of the body wall called the mantle. This portion of the animal's anatomy is responsible for secreting the shell. The mantle encloses the mantle cavity which contains the Ctenidia (gills), anus and excretory pores. Many mollusks have a radula, a tongue of sorts, which is rough like sandpaper and is used to rasp away at food. The radula is made of a hard material called chitin, the same material of which Arthropod exoskeletons are made.

How do you replace the ignition switch on a 1997 Chevy S-10 Blazer? Now remove the nut holding the steering wheel on and remove the steering wheel. BE VERY CAREFUL WITH THE AIRBAG MODULE!! Now remove the lower column cover with 2 Torx screws. You will now have access to 2 inverted Torx screws that hold the top column cover in place.Remove the hold-down ring that holds the cover to the shaft. Look on the top of the ignition cylinder housing and find the small hole.Insert a small Allen wrench into the hole and turn the key to run position and the ignition cylinder will come out, now the top cover will come off, giving access to the ignition switch.You will need the smallest inverted Torx bit for the 2 screws that hold the ignition switch in.ou will need the following tools: Steering wheel puller Torx bits (get a set, you need 3 sizes) Inverted Torx (a set is available at Schucks/Kragen/Checker Screwdriver A few zip ties Wire cutters. Start by disconnecting the yellow wire under the dash for the airbag.

- In general, mollusks have 3 body regions: a head, a visceral mass, and a foot.. The head contains the sense organs and brain, while the visceral mass contains the internal organs. The foot is the muscular lower part of the body which is in contact with the substrate.Mollusks usually have a shell (although some do not).Mollusks also have an extension of the body wall called the mantle.here are over 50,000 known species of Mollusks, which makes them second only to the Arthropods in invertebrate phylum size. Among the Mollusks are some of the most well known of invertebrate sea creatures, like snails, clams, mussels, squid, and octopods.

What is a Mollusk? In many bivalves and snails, and in cephalopods, part of the mantle is modified into a siphon, which can be used to pump water through the mantle cavity for respiration, feeding and/or jet propulsion. Freshwater and marine mollusks have gills (called ctenidia) for respiration, located in the mantle cavity. In most bivalves, these are enlarged and serve to trap food particles as well (Morton 1983).

Bivalves The mollusks that have a hinged, two-part shell joined by strong muscles are called bivalves. Clams, Oysters, and Scallops are bivalve mollusks and are a familiar food source.These three animals pull their shells closed by contracting powerful muscles near the hinge. The open these shells they have to relax their muscles.quid and octopuses have a well-developed nervous system and large eyes which are similar to human eyes. Cephalopods are the only mollusks that have closed circulatory system, which the blood contains food and oxygen that moves through the body in a series of closed vessels.

What is the visceral mass in mollusks and their function? Answers. Relevance. Rating Newest Oldest. Best Answer: Visceral mass in any animal means the soft organs lying in thorax & abdomen ----accordingly called as thorax viscera & abdominal viscera. In mollusks, the visceral mass consists of digestive, circulatory, excretory, reproductive & other organs. Each organ or organ system performs its specific function.
