Gizzard Wikipedia

The gizzard, also referred to as the ventriculus, gastric mill, and gigerium, is an organ found in the digestive tract of some animals, including archosaurs (pterosaurs, crocodiles, alligators, dinosaurs including birds), earthworms, some gastropods, some fish, and some crustaceans.This specialized stomach constructed of thick muscular walls is used for grinding up food, often aided by

Evidence for a persistent Na+ conductance was obtained in identified motor neurons of the gastric mill network in the stomatogastric ganglion of the spiny lobster Panulirus interruptus. The cells studied were the lateral gastric and lateral posterior gastric motor neurons, which in vivo control chew

7: Lobsters Have Two Stomachs 10 Weird Facts About

This stomach contains teeth-like features (called a gastric mill) that are used to crush the lobster's food. Once the food is fine enough, it passes to the other stomach. Most of a lobster's abdomen is taken up by a digestive gland that serves as the filtration system -- sort of like your liver.

Neural mechanisms underlying the generation of the lobster

The lobster gastric mill central pattern generator (CPG) is located in the stomatogastric ganglion and consists of 11 neurons whose circuitry is well known. Because all of the neurons are identifiable and accessible, it can serve as a prime experimental model for analyzing how microcircuits generate multiphase oscillatory spatiotemporal patterns.

Malacostracan Form and function Britannica

Malacostracan Malacostracan Form and function: The chitinous exoskeleton, or cuticle, covering the body and limbs of malacostracans is divided into segments interconnected by strong, flexible membranes, allowing for articulation at the joints. The cuticle is usually soft and thin in small, wormlike, generally subterranean species, in parasitic species, or in the respiratory surfaces of

Stomatogastric ganglion Scholarpedia

Oct 30, 2013· The stomatogastric ganglion is a collection of about thirty neurons that sits on the dorsal surface of the foregut (stomach) in decapod crustaceans. The neurons it contains form two central pattern generators (CPGs), namely the pyloric and gastric mill CPGs. The pyloric CPG controls striated muscles that dilate and constrict the pyloric region of the stomach in a cyclic three phase rhythm.

Additionally, while the dorsal gastric neuron in the crab most often fired in strong bursts that were independent of the remaining gastric mill neurons, the enhanced firing induced by pyrokinins in the dorsal gastric neuron in the lobster was always coordinated with the other gastric mill neurons.

Crustacean Form and function of internal features

Crustacean Crustacean Form and function of internal features: The crustacean nervous system consists basically of a brain, or supraesophageal ganglion, connected to a ventral nerve cord of ganglia, or nerve centres. In primitive forms, like the anostracan fairy shrimps, the brain has nerve connections with the eyes and antennules, but the nerves to the antennae come from the connecting
