Nervous system,
the nervous system of an earthworm. Operators have a two-lobed brain. Because of esophageal ganglion front welded together over one pair of esophageal ganglia brain over the nerves around the larynx, pharynx articulate the three second bypass line around the side of the throat. The stomach is a large nerve. The segmental ganglion over every segment. Earthworms also Without any sense organ. Only cells sense (Sensory Cells) scattered areas of skin. The cells sense each cell has tiny hairs. Held out to get a feel from the external environment. Which cells sense these are connected to the nervous system. The cells then feel There are photoreceptors (Photoreceptor cells) in the episode der Miss. There will be more on the lips. Segment header and footer of the body. Has been feeling about the light to the nervous system. If there is too much light, it moves away into the
reproductive system
of earthworms are animals that have both ovaries and testes. In the same Generally do not mix in itself because the reproductive organs of both sexes and not connected with reproduction and not simultaneously. Earthworms do so on a reciprocal exchange sperm
reproductive organs include
the testes 1. (Testes) is a small white lumps protruding from the wall of the segment
two. Hopper capacity of sperm (Sperm funnel) to channel sperm from the testis
3. Sperm duct (Vas deferens) sperm from a pipe hopper to. Male Reproductive channel
4. Prospect Estates gland (Prostate gland) is a large white shaped gland. A cube-like branching twigs one pair generates liquid nourish sperm
fifth. Detective channel breeding males (male pores) in the ventral segment has one pair of 18
6. bag sperm (Seminal Vesicles) with two doubles, a large bag in the crater at 11 and 12 acts and development. sperm from the testes to create organs. Breeding females include : 1. ovaries (Ovaries) generates eggs one pair stuck to the membrane barrier (Septum) of the 12/13 segment in Pheretima eggs arranged in a row in puma ovarian second. Hopper capacity eggs (Ovarian funnel) served with eggs. Full-grown from the egg sac 3. Oviduct (Oviducts) oviduct is a tube that goes from the hopper supports 13 eggs in that segment open to female holes. The center of the segment at 14 4. sperm to the Ravens (Spermatheca or Seminal receptacles) a bag with sperm from another pairing exchange. To keep the eggs are mixed with three pairs of earthworms 1.3 Appearance Appearance depictions of earthworms is that the body is. Segment from the head to the end. The shape is cylindrical, with a length of each type is different. When fully grown, they are articulate about 120 segments, each segment will have a small spur. Sort by around hydrothermal No clear head without eyes Crichton Tellus, which is obvious. Reproduction in It also contains important organs (Figure 3) 1. Prosser's speakers (Prostomium) has a retractable pool area attached to the top surface of the mouth is the front end of an earthworm. Acts like lip Not considered a segment Is responsible for sweeping the food into his mouth 2. peristome speakers (Peristomium) This is the first segment of the earthworm. Features a thin beef Around the mouth and retractable three. Oral 1-3 in the crater at the channel entrance of food into the body. Which are the salivary glands in the lining of the mouth by 4 months or wool (Setae) looks like a stubby short. The substance chitin. That grew out of the outer wall. Can stretch, shrink or expand This month there To help with adhesion and movement of earthworms 5. Open the back (Dorsal pore) is the small openings in the grooves between the segments along the middle after opening this type can be found in almost all species of earthworms. The earthworm species that live in water or half water. During the first segment in the groove The header will not find an opening on the back. Such openings are connected to the torso and fluid in the body. Is responsible for driving fluid or mucus in the body to help the body outside and moist. Anti-inflammatory Make simple movements 6. True excrete waste (Nephridiopore) is a very small hole. Noticeable The hole for the drive waste out of the body. The external orifice Which is almost every segment except the first segment 3-4 7. Male Reproductive channel (Male pore) is a channel for releasing sperm will have one pair located on the belly or side of the body. In each species, the reproductive segment is not the same. The basin is similar to a long tube into the female reproductive channel 8. (Female pore) is the channel for eggs. Generally located in the crater next to articulate the ovaries (avary) usually found only one couple in the groove on the segment or segments. The location is different in each nematode species 9. openings sperm to the Ravens (Spermathecalporse) as channels sperm from another doubles as earthworms. The exchange sperm fertilize each other. When sperm is stored in a storage bag sperm (Seminal Receptacle) 10. Reproduction lever (Genital papilla) is the organ that helps to hold as earthworms. Pair mating 11. Crichton Tellus m (Clitellum) is an organ that is used to create egg white coat. And create mucus cocoon Tellus client will be found in earthworms grow together only at mating. It is located near the front segment header. Plong Plong comprehensive 2-5 12. anus (Anus) is open to the board. The narrow opening in the last segment. Which is used to drive through food waste digestion and absorption, and then out of the body.
