What are the green glands?
Paired maxillary and antennal glands (also called green glands) are the principal excretory organs in crustaceans. The “labyrinth” of the antennal gland is also involved in reabsorption of glucose, amino acids, and divalent ions from tubule fluids.
What animals have green glands?
Mollusks. Hint: Green glands or the antennal glands are paired glands in prawns, shrimps, etc. They help in the elimination of ammonia waste from the body. They are one of the excretory organs seen in Arthropods.
What is the function of a green gland?
antennal gland (green gland) Either of a pair of ducts (coelomoducts) found in the third segment of a crustacean and opening to the exterior at the base of the second antenna. They function as osmoregulatory organs.
What is a green gland in zoology?
n. (Zoology) one of a pair of excretory organs in some crustaceans that open at the base of each antenna.
Are green glands green?
In many higher crustaceans the excretory glands are located in the head. They are called antennal glands or maxillary glands, depending on whether they open at the base of the antennae or at the maxillae. If the tubule adjacent to the excretory pore is green, the gland is called a green gland.
Where are green glands located?
coxal gland
In many higher crustaceans the excretory glands are located in the head. They are called antennal glands or maxillary glands, depending on whether they open at the base of the antennae or at the maxillae. If the tubule adjacent to the excretory pore is green, the gland is called a green gland.
Do prawns have green glands?
The main excretory organs of prawn are paired green glands. They are located within the second antennae which are the second pair of appendages, attached to the anterior part of the body. Each green gland consists of on endsac, labyrinth and a bladder.
Do cockroaches have Coxal?
In cockroach, excretion is mainly performed by one or two pairs of malpighian tubules. One of this pair opens into the middle region of intestine and other pair of coxal glands are located in prosoma and opens at bases of fifth walking legs.
Do Scorpions have green glands?
<br> [R] : The coxal glands of scorpion are analogous with the green glands of crustacea and function as excretory organs .
Do sharks have salt glands?
The salt gland is an organ for excreting excess salts. It is found in the cartilaginous fishes subclass elasmobranchii (sharks, rays, and skates), seabirds, and some reptiles. Salt glands can be found in the rectum of sharks.
What is the meaning of preen gland?
preen gland, also called Uropygial, or Oil, Gland, in birds, an organ located on the back near the base of the tail. ... The secretions of the preen gland empty to the skin surface through one or more nipplelike pores.
Why do crayfish have antennal glands?
They function as osmoregulatory organs. For example, in the antennal gland of the freshwater crayfish (Astacus), fluid is filtered from the blood into an end sac and passes through a tubular labyrinth, where ions are reabsorbed, to produce a hypotonic urine that passes via a renal tubule to the bladder.
Do mites have Coxal glands?
Crustaceans and arachnids possess paired excretory organs (maxillary, antennal, or coxal glands) that open at the bases of certain appendages. Myriapods, insects, and some arachnids, such as spiders and mites, possess another type of excretory organ, Malpighian tubules, which open into the intestine.
What are endocrine glands?
An organ that makes hormones that are released directly into the blood and travel to tissues and organs all over the body. Endocrine glands help control many body functions, including growth and development, metabolism, and fertility. Some examples of endocrine glands are the pituitary, thyroid, and adrenal glands.
Where would you look Coxal glands?
The coxal gland is a gland found in some arthropods, for collecting and excreting urine. They are found in all arachnids (with the exception of some Acari), and in other chelicerates, such as horseshoe crabs. The coxal gland is thought to be homologous with the antennal gland of crustaceans.
