The Malpighian tubule system is a type of excretory and osmoregulatory system found in some insects, ... Malpighian tubules of a dissected cockroach, indicated by ...
They act by increasing cyclic AMP production in Malpighian tubules and appear to stimulate cation (K + /Na +) transport. Originally known as the myokinins because of their myotropic activity, the kinins were first isolated from the Madeira cockroach, Leucophaea maderae and the cricket, Acheta domesticus. Kinins are smaller than the CRF-related ...
Plasmodia inhabit and feed on Malpighian tubule cells where they are in direct contact with the cytoplasm. Multi-nucleate plasmodia are eventually released into the lumen, some attach to the brush border of the tubule cells using pseudopodia that interdigitate with the microvilli of the cells. Other plasmodia form merozoite-like cells.
An insect uses its digestive system to extract nutrients and other substances from the food it consumes. [3]Most of this food is ingested in the form of macromolecules and other complex substances (such as proteins, polysaccharides, fats, and nucleic acids) which must be broken down by catabolic reactions into smaller molecules (i.e. amino acids, simple sugars, etc.) before being used by cells ...
Stylized diagram of insect digestive tract showing malpighian tubule, from an insect of the order Orthoptera. The first section of the alimentary canal is the foregut (element 27 in numbered diagram), or stomodaeum. The foregut is lined with a cuticular lining made of chitin and proteins as protection from tough food.
Cockroaches are experts at surviving indoors, hiding in kitchen pipes or musty drawers. A new study uses genetics to chart cockroaches' spread across the globe, from humble beginnings in southeast ...
Polytene chromosomes are present in secretory tissues of dipteran insects such as the Malpighian tubules of Sciara and also in protists, plants, mammals, or in cells from other insects. Some of the largest polytene chromosomes described thus far occur in larval salivary gland cells of the chironomid genus Axarus.
