Parental Care

Parental Care

Many animals exhibit parental care behavior, including feeding, grooming, and protecting young offspring. Parental care is universal in mammals and birds, which often have young that are born relatively helpless. Several species of insects and fish, as well as some amphibians, also care for their young.

What is Monogastric Digestion?

What is Monogastric Digestion?

The human body contains a monogastric digestive system. In a monogastric digestive system, the stomach only contains one chamber in which it digests food. Several other animal species also have monogastric digestive systems, including pigs, horses, dogs, and birds. This chapter, however, focuses on the human digestive system.

What is Behavior?

What is Behavior?

Behaviors are actions that an organism engages in—they can be related to finding food, reproducing, defending against threats, and many other possible actions. Behaviors include activities related to the environment around the animal—such as migration—as well as social interactions within a species or population. Many behaviors involve motor output—that is, muscle movements—while others involve less visible actions, such as learning.

Enteral Nutrition II: Nasointestinal and Gastrostomy Feeding

Enteral Nutrition II: Nasointestinal and Gastrostomy Feeding

Enteral nutrition encompasses various methods of delivering nutrition directly to the gastrointestinal (GI) tract, bypassing traditional oral intake. It is particularly beneficial for patients who cannot eat by mouth but have a functioning digestive system. Key methods include nasointestinal feeding, gastrostomy, and jejunostomy, each suited to different clinical scenarios based on the patient's needs and condition.

Optimal Foraging

Optimal Foraging

How animals obtain and eat their food is called foraging behavior. Foraging can include searching for plants and hunting for prey and depends on the species and environment.

Physiology of the Gastrointestinal System I: Ingestion and Propulsion

The physiology of the gastrointestinal system begins with ingestion as food enters the mouth.

Area of Science:

Neuroscience
Metabolism
Endocrinology

Background:

Mammalian feeding behavior and energy balance are complex processes.
The brain, particularly the hypothalamus, integrates numerous signals to regulate these processes.

Purpose of the Study:

To elucidate the intricate mechanisms of central appetite regulation.
To highlight the role of the hypothalamus as a key integrator of metabolic and nutritional information.
To explore the potential for novel therapeutic strategies for obesity based on appetite control.

Main Methods:

Review of central and peripheral signaling pathways involved in feeding.
Analysis of hypothalamic neuronal circuits and their integration of homeostatic feedback.
Examination of intracellular energy sensing mechanisms and their impact on neuronal activity.

Main Results:

The hypothalamus integrates humoral and neuronal signals related to nutritional and energy status.
Peripheral organs provide homeostatic feedback to the hypothalamus, influencing feeding behavior.
Intracellular adaptations, such as AMP-activated protein kinase activation, occur in hypothalamic neurons.

Conclusions:

The brain's complex integration of signals is crucial for maintaining energy homeostasis.
Understanding these regulatory pathways offers promising avenues for obesity treatment development.
