The gastrointestinal tract, responsible for the digestion and absorption of nutrients, is safeguarded by the intestinal barrier, which consists of secretory, physical, and immune components. At the forefront is the secretory barrier, composed of essential elements such as mucus, gut microbiota, and defense proteins. They collaborate to break down food particles, facilitate nutrient absorption, and maintain optimal gut health. These secretory components ensure the smooth functioning of the...

This study outlines a protocol for generating 2D monolayers of porcine organoids derived from the small and large intestines. The growth of these monolayers is marked by increasing TEER values, indicating robust epithelial integrity. Additionally, these monolayers exhibit physiological secretory responses in Ussing chamber experiments following the application of forskolin.

In this report we demonstrate techniques that can be used to investigate the biology of the crayfish hindgut. We show how to dissect a crayfish abdomen and study the associated anatomy, physiology and modulation of activity. The peristaltic activity and strength of contractions are measured using a force transducer.

Homeostasis Conditions in the external environment of an organism can change rapidly and drastically. To survive, organisms must maintain a fairly constant internal environment, which involves continuous regulation of temperature, pH, and other factors. This balanced state is known as homeostasis, which describes the processes by which organisms maintain their optimal internal conditions. To maintain homeostasis, organisms have developed structures with distinct functions. Physiology is the...

Sensory neurons monitor mechanical and chemical conditions within the gastrointestinal tract. Their signals activate local reflexes that coordinate smooth-muscle activity for peristalsis and adjust secretion according to the gut environment. This arrangement allows the intestine to respond locally while linking sensory detection to the movement and processing of contents through the digestive system.
The enteric nervous system provides neural control within the gastrointestinal tract, coordinating functions such as motility and secretion through local circuits. Autonomic pathways connect gut activity with broader nervous-system regulation. Considering both systems helps explain how digestion can be organized locally while remaining responsive to signals associated with whole-body homeostasis and gut-brain communication.
Epithelial cells help maintain the gut’s barrier while participating in the regulated environment through which neural and chemical signals operate. Endocrine signals add another layer of coordination between gastrointestinal activity and nervous-system control. Together with smooth muscle and neural elements, these components influence how digestion, secretion, and intestinal conditions are integrated rather than controlled by a single cell type.
Gut-brain signaling carries information between gastrointestinal processes and neural systems that regulate internal balance. These signals contribute to visceral sensation, meaning awareness of internal gut conditions, and influence appetite and homeostasis. The same communication framework also helps researchers examine how stress responses relate to gastrointestinal function, making it important for neuroscience studies of body-brain integration.
A neuroscience-focused investigation should examine how neural circuits interact with smooth muscle, epithelial cells, endocrine signals, and autonomic pathways. It should also consider the sensory information generated by mechanical and chemical conditions in the gut. This broader view connects digestive activity with motility, secretion, visceral sensation, appetite, stress responses, and maintenance of homeostasis.
Research can identify how altered communication among enteric circuits, sensory neurons, autonomic pathways, and gut tissues affects gastrointestinal function. Examining these interactions provides context for disorders involving digestion, motility, secretion, or gut-brain signaling. It also supports investigation of therapies that target communication between the gastrointestinal tract and the nervous system rather than focusing on one component alone.
