Bivalve - Bivalve - Internal features: The general classification of the bivalves is typically based on shell structure and hinge and ligament organization. They direct the trapped food toward the mouth. How do clams breathe? Where are the palps found and what is their function? 13. 8. What is the function of the tooth-like projections at the dorsal edge of the clam’s valves? What is its function? Why are clam's referred to as "filter feeders"? Where are the palps found and what is their function? 12. Where are the palps found and what is their function? The obvious question to anyone who sees this species is, “Why the curiously enlarged palps?” Both males and females exhibit this character (even as juveniles), so it seems clear that there is no special sexual or hypersensory function. The histology of the pit sensilla and their central projec- tion have been studied in Pieris rapae (Pieridae) by Lee et al. These are commonly found on the antennae, though they also occur on the maxillary palps of Lepidopteran larvae and the ovipositor of the Blowfly Phormia regina. … 7. Where are the palps found and what is their function? How do clams breathe? The probable function of the maxillary and labial palps of grasshoppers are chemosensory function. 10. 9. 12. About 35 trichoid sensilla, sorted into three different classes according to their lengths, are present on the two labellar lobes. Scanning electron microscopy was also used to assess the types of sensilla found on the two organs. What is the mantle cavity? Pedipalp definition is - either of the second pair of appendages of various arthropods (such as an arachnid or horseshoe crab) that lie on each side of the mouth and often perform a specialized function (such as grasping or feeling). 10. Where is the mantle located in the clam? 11. Pedipalps of spiders have the same segmentation as the legs, but the tarsus is undivided, and the pretarsus has no lateral claws. 10. Where is the mantle located in the clam? Carefully peel away the muscle layer to view the internal organs. 13. 14. The maxillary palp between the antennae pick up the odor of ocentol and other chemicals released in human sweat. 11. Where are the palps found and what is their function? Where is the clam's heart located? Proboscis . These sensilla measured approximately 16 μm (16.2 ± 1.30 μm) in length, and the tip, a bulbous structure like a club head, was 2.62 ± 0.18 μm wide ( Figure 1 c). 9. palp (pălp) n. One of a pair of elongated, often segmented appendages usually found near the mouth in invertebrate organisms such as mollusks, crustaceans, and insects, the functions of which include sensation, locomotion, and feeding. In some crustaceans, palps perform a locomotory function and in others are associated with feeding, as they are in bivalve molluscs where they produce feeding currents. 11. 17. 15. 8. Where are the palps found and what is their function? 8. The internal anatomy is also a tool in classification, particularly the organs of the mantle cavity, the pattern of water movement through it, and the structure and functioning of the ctenidia and labial palps. Where is the mantle located in the clam? 11. Sensilla coeloconica or pit-peg organs, these are always situated in a pit as their common name suggests, unlike the previous two which project above the insect’s cuticle. How to Cook Clams. The types and distribution of the sensilla on the maxillary and labial palps were highly similar between males and females. Where are the palps found and what is their function? 14. 11. What helps direct water over the gills? What is the function of the tooth-like projections at the dorsal edge of the clam’s valve? In insects, palps are found on the first and second maxillae, where they are thought to be associated with olfaction. Describe the movement of food from the current siphon through the dig How do clams breathe? 14. Describe the clam’s foot. Describe the clam's foot. Results showed that only oocytes co-expressing HarmGr1 and HarmGr3 or co-expressing HarmGr1, HarmGr2 and HarmGr3 gave robust responses to NaHCO3. • Muscle attachments are roughly similar to those of the mandibles. - 13878161 Why are clam's referred to as "filter feeders"? Where are the palps found and what is their function? How do clams breathe? Also called palpus. What helps direct water over the gills? Where is the clam's heart located? (1986). Describe the movement of food from the current siphon through the digestive system of the clam. The ciliation and structure of the labial palps of the nuculid Acila castrensis have been investigated and found to be extremely complex. Why are clam's referred to as "filter feeders"? Where is the mantle located in the clam? These authors found a peculiar combina- Next, we employed the Xenopus laevis oocyte expression system and the two-electrode voltage-clamp recording to study the function of the three genes. The controversy about the number of articles making up the ovigers and palps is an open question. The labial palps consist of three segments. Describe the movement of food from the current siphon through the digestive system of the clam. Where is the clam's heart located? What is its function? Describe the movement of food from the current siphon through the digestive system of the clam. 8. What helps direct water over the gills? 10. 12. Labial palp function in freshwater bivalves requires further study. Their antennae, long feathery organs, jut forward from their heads and contain sensitive receptors that detect carbon dioxide in human breath from distances of more than 100 feet. Where is the clam's heart located? Their density did not vary across the length or over the dorsal or ventral surface. 6. What helps direct water over the gills? 7. Beneath the palps, find the mouth. *the posterior end of the clam. 8. Where is the mantle located in the clam? In addition, the maxillary palps were relatively less sensitive to plant-derived odorants than the antennae, perhaps related to their anatomical position. 11. What is the mantle cavity? 16. With scissors, cut off the ventral portion of the foot. How do clams breathe? 9. Cano and López-Gonzalez discussed the 10- or 11- articled nature of the ovigers in the Colossendeis species based on their similarities with the basal parts of palps. *The inside layer of the shell. What is its function? What helps direct water over the gills? 18. Also called palpus. Which type of cell has organelles that are bound? If a 10- articled palp is considered, an 11- articled oviger should not be rejected; both considerations seem to be linked. of their labial palps are responsive to CO2. 13. 10. Describe the clam’s foot. Use the scalpel to carefully cut the muscle at the top of the foot into right and left halves. 9. What is the function of the tooth-like projections at the dorsal edge of the clam's valves? (1985) and Lee and Altner (1986) and in Manduca sexta (Sphingidae) by Kent et al. What is the mantle cavity? This is a question and answer forum for students, teachers and general visitors for exchanging articles, answers and notes. Where are the palps found and what is their function? What is the function of the tooth-like projections at the dorsal edge of the clam’s valve?
