Sympatho-Adrenal (SA) system and the Hypothalamic-Pituitary-Adrenal (HPA) system.
Anatomical mechanisms refer to the physical structures involved in a particular function; physiological mechanisms involve the biochemical and biophysical processes that enable that function; cellular mechanisms involve the activities of individual cells that contribute to the overall function or structure. These mechanisms work together to dictate the performance parameters of a system, such as strength, speed, or endurance.
Physiological antagonists are substances that have opposing effects on effector organs but do not directly inhibit each other's action. They work by different mechanisms to achieve opposite physiological effects, such as regulating blood pressure or heart rate. This allows for fine-tuning of responses to maintain homeostasis in the body.
Hormones are released in response to feedback mechanisms that help regulate various physiological processes in the body.
Feedback mechanisms help an organism maintain homeostasis by detecting changes in internal conditions and initiating responses to counteract these changes. Negative feedback loops work to bring the system back to its set point, while positive feedback loops amplify the initial change. Together, these mechanisms help ensure that an organism's internal environment remains stable despite external fluctuations.
In addition to pain receptors in the brain, other mechanisms that can cause headaches include changes in blood flow, chemical imbalances, muscle tension, and nerve irritation.
Describe the body's mechanisms for controlling blood glucose levels under normal and stress conditions.?
Physiological mechanisms underlying a trade-off between growth rate and tolerance of feed deprivation in the European sea bass
psychophysiological - conditions/ stress responses that have both mind and body components
It's used by internal physiological mechanisms of several species of insects, fish, birds, and animals. When used by humans, we don't have those physiological mechanisms, or at least if we have them we don't know how to use them, so we use the magnetic compass.
Negative feedback mechanisms maintain homeostasis by detecting changes in the internal environment and initiating responses to counteract those changes. For example, when body temperature rises, mechanisms such as sweating are activated to cool the body down. Similarly, if blood glucose levels drop, the release of hormones like glucagon increases glucose production. This continual adjustment helps stabilize physiological functions despite external fluctuations, ensuring optimal conditions for survival.

Feedback mechanisms such as negative feedback play a key role in restoring normal function when a physiological variable gets out of balance. Negative feedback works by detecting changes in variable levels and initiating responses to counteract those changes, ultimately bringing the variable back into the normal range. This helps maintain homeostasis and ensure the body's optimal functioning.

Immediate mechanisms for a behavior refer to the proximate causes or triggers that directly influence an individual's action. These mechanisms can include physiological processes like hormone release, neural activation, or sensory stimuli that lead to the displayed behavior.
Physiological antagonists are substances that have opposing effects on effector organs but do not directly inhibit each other's action. They work by different mechanisms to achieve opposite physiological effects, such as regulating blood pressure or heart rate.

The medulla oblongata is located at the base of the brainstem and is responsible for controlling vital involuntary functions such as breathing, heart rate, and blood pressure. It also plays a role in reflexes like coughing, sneezing, and swallowing.
