Regulation of tissues, organs, and systems through nervous system activity

Quick, accurate, short duration

Mainly regulates muscles and glands, regulated by reflexes

Certain chemicals secreted by certain cells are transported to target cells through body fluid transport (blood, tissue fluid, lymph) and act on the corresponding receptors, thereby changing the physiological activities of the receptors.

slow, persistent, diffuse

Mainly regulates body metabolism, growth and development, reproduction

Classification

The process by which certain tissues or organs respond adaptively to stimuli without neural or humoral regulation.

The adjustment is weak, the range is small, and the sensitivity is low

Assists in neuroregulation and body fluid regulation

The glomerular afferent arteriole regulates glomerular filtration rate, myocardial heterogeneity regulates itself, and maintains blood pressure stability according to renal/cerebrovascular perfusion pressure.

plasma, tissue fluid, lymph, cerebrospinal fluid

Negative feedback

Positive feedback

Athletes are nervous before a race, and people secrete gastric juices while looking at the food before eating.
