What is the difference and connection between neuromodulation and humoral modulation?

The relationship between neuromodulation and humoral regulation: Many endocrine glands themselves are directly or indirectly regulated by the central nervous system, and humoral regulation can be regarded as a link in neuromodulation Hormones secreted by endocrine glands can also affect the development and function of the nervous system. (Neuromodulation and humoral regulation exist simultaneously in animals, and both are the basic forms of the body's regulation of vital activities.)

On the one hand, most of the endocrine glands in the body are controlled by the central nervous system, such as the secretion of sex hormones is regulated by the central nervous system; On the other hand, hormones secreted by endocrine glands can also affect the function of the nervous system, such as thyroid hormones, which are necessary for the growth and development of the brain. In the above two regulatory roles, the life activities of animals are mainly regulated by the nervous system. )

Differences between neuromodulation and humoral modulation.

Compare items of neuromodulation and humoral regulation.

Mode of action Reflex arc transport of body fluids.

The reaction speed is rapid and slower.

The scope of action is accurate and relatively limited, and it is wide.

The duration of action is short-lived and relatively long.

The endocrine glands are directly or indirectly regulated by the central nervous system.

In turn, humoral regulation has an effect on the nervous system.

For example, one of the several functions of thyroid hormone involves its ability to increase the excitability of the nervous system and is related to the development of the nervous system.

On the other hand, hormones secreted by endocrine glands can also affect the development and function of the nervous system.

For example, thyroid hormone deficiency in early childhood will affect brain development; In adulthood, insufficient thyroid hormone secretion can reduce the excitability of the nervous system.

In short, the various life activities of the animal body are often regulated by both nerves and body fluids. It is precisely because of the coordination of these two modes of regulation that the activities of various organs and systems can be coordinated, the homeostasis of the internal environment can be maintained, the life activities of cells can be carried out normally, and the body can adapt to the continuous changes of the environment.

1. Different modes of action:

Neuromodulation is regulated by reflex arcs, whereas humoral regulation is regulated by humoral transport.

2. The reaction speed is different

The neuromodulation response is rapid, while the humoral modulation response is slower.

3. The action time is different

The neuromodulation time is relatively short, and the humoral adjustment time is relatively long.

Connection: The endocrine glands are regulated by the central nervous system, and humoral regulation can be regarded as a link of neuroregulation; Fluid regulation also has an effect on the nervous system, and hormones can affect the development and function of the nervous system, and both often regulate vital activities at the same time.

For example, one of the several functions of thyroid hormone involves its ability to increase the excitability of the nervous system and is related to the development of the nervous system. On the other hand, the hormones secreted by the endocrine glands can also affect the development and function of the nervous system, such as the lack of thyroid hormone in childhood, which will affect the development of the brain; In adulthood, insufficient thyroid hormone secretion can reduce the excitability of the nervous system.

Neuromodulation and.

The difference between fluid regulation:

1. Different pathways of action.

Neuromodulation is through the internal perflex arc, while fluid volume regulation is through fluid transport.

2. Reaction speed.

Neuromodulation is rapid, while humoral regulation is slower.

3. Scope of action.

Neuromodulation is more accurate, while humoral regulation is more limited and more extensive.

4. Action time.

The neuromodulation time is relatively short, and the humoral regulation is relatively long.

Relationship: The endocrine glands are regulated by the central nervous system, and humoral regulation can be seen as a link in neuromodulation.

Hormones can also affect the development and function of the nervous system, and both often regulate vital activities at the same time.

Examples: For example, the adrenal medulla is innervated by the sympathetic nervous system, and when the sympathetic nervous system is excited, the adrenaline medulla secretes an increase in adrenaline and norepinephrine, which are jointly involved in the regulation of the body.

There is a feedback regulation between hormones and the secretion system, and feedback regulation is that under the influence of the cerebral cortex, the hypothalamus can regulate and control the synthesis and secretion of hormones in some endocrine glands through the pituitary gland;

After hormones enter the bloodstream, they can in turn regulate the synthesis and secretion of hormones related to the hypothalamus and pituitary gland. Through feedback regulation, hormones in the blood are often maintained at relatively stable levels of normal.

What is the difference between neuromodulation and humoral modulation?

Neuromodulation is the direct action of transmitters on the body through neurons, which has a fast effect but a small range, and humoral regulation is the regulation of body secretions to the body through lymph, and the effect is slow.

The range of fast neuromodulation is small, and the range of slow humoral regulation is wide.
