- Earthworm-Nervous System. The earthworm has a simple yet sensitive nervous system. Its cerebral ganglion, or brain, is connected to the ventral nerve cord, which runs the length of its body. At each segment, segmental ganglion branch off from the ventral nerve cord, thus connecting every segment to the earthworm's brain.

- Pulsed electromagnetic field therapy (PEMFT), also called pulsed magnetic therapy, pulse magnetotherapy, or PEMF, is a reparative technique most commonly used in the field of orthopedics for the treatment of non-union fractures, failed fusions, congenital pseudarthrosis and depression.f you intend to use the system for more than one treatment cycle in a row, you may want to put a towel between you and the paddle so that the heat does not become uncomfortable. I have been using pulsing electro-magnetic field therapy for about three years now.

- We got the oppertunity to disect a dead earthworm and to explore the inside of the worm. The objectives of this dissection was to describe the appearance of various organs found in the earthworm, and also to name the organs that make up the various systems of the earthworm.n the intestine, which extends over two-thirds of the body lenght, digestion and absorbsion take place. The gizzard is a muscular organ used to churn the food and then it moves onto the intestine where absorbtion of the food occurs. 8. Your dissection of the earthworm did not go beyond segment 32.

Earthworm An earthworm is a tube-shaped, segmented worm found in the phylum Annelida. They are commonly found living in soil, feeding on live and dead organic matter.Its digestive system runs through the length of its body. It conducts respiration through its skin.arthworm is the common name for the largest members of Oligochaeta (which is either a class or a subclass depending on the author).

Brain 1 In some primitive fishes, such as lampreys, this region is the largest part of the brain. 2  The superior colliculus is part of the midbrain. 3  The pallium is a layer of gray matter that lies on the surface of the forebrain and is the most complex and most recent evolutionary development of the brain as an organ.he brain is small and simple in some species, such as nematode worms; in other species, including vertebrates, it is the most complex organ in the body. Some types of worms, such as leeches, also have an enlarged ganglion at the back end of the nerve cord, known as a tail brain.

Earthworm An earthworm has a double transport system composed of coelomic fluid that moves within the fluid-filled coelom and a simple, closed blood circulatory system. Chemical: In addition to dead organic matter, the earthworm also ingests any other soil particles that are small enough—including sand grains up to 1/20 of an inch (1.25 mm)—into its gizzard, wherein those minute fragments of grit grind everything into a fine paste which is then digested in the intestine.

- We will use in the earthworm as our model animal, an Oligochaete (Evolutionary school-subclass, phylogenetic school, not sure), belonging to the class or clade Clitellata, or Annelids with a clitellum, a swelling towards the head of the animal. The other two major clades are the Polychaeta and Echiura.e will be comparing the earthworm to a typicalleech, (Subclass Hirudinea), also a Clitellate. The Hirudinea resemble the oligochaetes in their major habitats (fresh water and land) as well as in lack of parapodia and reduction of specialized head structures that we will find in the Polychaeta.

What structure in the eathworm has a similar function as the human heart explain? Best Answer: The earthworm has a closed circulatory system. An earthworm circulates blood exclusively through vessels. There are three main vessels that supply the blood to organs within the earthworm. These vessels are the aortic arches, dorsal blood vessels, and ventral blood vessels. The aortic arches function like a human heart. There are five pairs of aortic arches, which have the responsibility of pumping blood into the dorsal and ventral blood vessels. The dorsal blood vessels are responsible for carrying blood to the front of the earthworm’s body.

Types of Worms Earthworms can be found at just about every corner of the earth. They live in trees, in bark, and under rocks as well as along rivers and near springs, and ponds.orms feed off of leaves and dead grass which contain organisms that provide a healthy diet of bacteria, algae, and fungi to the worm. Worms feast on dirt as well, especially if they live deeper inside the earth. Worms also eat plants, fruits, and vegetables. Believe it or not, worms do have mouths.

Earthworm Digestive system The gut of the earthworm is a straight tube which extends from the worm's mouth to its anus. It is differentiated into a buccal cavity (generally running through the first one or two segments of the earthworm), pharynx (running generally about four segments in length), esophagus, crop, gizzard (usually) and intestine.

earthworm dissection The mixture enters the pharynx, which is located in segments 1 6. The esophagus, in segments 6 13, acts as a passageway between the pharynx and the crop. The crop stores food temporarily. The mixture that the earthworm ingests is ground up in the gizzard. In the intestine, which extends over two-thirds of the body length, digestion and absorption take place. Soil particles and undigested organic matter pass out of the worm through the rectum and anus.

Earthworm An earthworm is a tube-shaped, segmented worm found in the phylum Annelida. They are commonly found living in soil, feeding on live and dead organic matter.Its digestive system runs through the length of its body. It conducts respiration through its skin.arthworms are hermaphrodites, that is, they have both male and female sexual organs. The sexual organs are located in segments 9 to 15. Earthworms have one or two pairs of testes contained within sacs. The two or four pairs of seminal vesicles produce, store and release the sperm via the male pores.

- The brain is located in the head, usually close to the primary sensory organs for such senses as vision, hearing, balance, taste, and smell. The brain is the most complex organ in a vertebrate's body.In a typical human, the cerebral cortex (the largest part) is estimated to contain 15–33 billion neurons, each connected by synapses to several thousand other neurons.he brain is small and simple in some species, such as nematode worms; in other species, including vertebrates, it is the most complex organ in the body. Some types of worms, such as leeches, also have an enlarged ganglion at the back end of the nerve cord, known as a tail brain.

Nervous system Flatworms, for example, have a pair of ganglia that function like a simple brain. The ganglia are attached to two nerve cords that run the length of the worm's body. These two cords are attached to each other by other nerves. This kind of nervous system is sometimes described as a ladder-type nervous system.

Earthworm: Digestive System The blood carries the nutrients to all parts of the earthworm’s body. 7. anus The worm’s intestine basically runs the length of the worm’s body. At the worm’s rear end the intestine ends. The end of the intestine, called the anus, is open and it is here where waste is excreted from the worm’s body.

How can you tell a worm's head from his tail? The earthworm's long body is tapered at both ends and there are no eye catching features to tell which end is which. However, with a little patience plus a small helping of know how you can tell his head from his tail. This information may not seem too important to a human, but it is vital to an earthworm.
