Answer 2

Nervous Regulation vs. Humoral Regulation

The nervous system and the humoral system are two major systems involved in regulating the activities of the body. While both systems play important roles, there are several characteristics that suggest that nervous regulation is a more progressive system compared to humoral regulation. These characteristics include:

A) Evolutionary Younger Form of Regulation: The nervous system is considered to be a more evolutionarily recent form of regulation compared to the humoral system. The development of a centralized nervous system allowed for more precise and rapid control over the body's functions. This is supported by the fact that even simple organisms like worms have a basic nervous system, whereas humoral regulation is found in a wider range of organisms, including plants and invertebrates [[1]].

B) Signal Transmission - Nerve Impulses: The nervous system relies on the transmission of electrical signals called nerve impulses to communicate information throughout the body. Nerve impulses are generated by specialized cells called neurons and can travel rapidly along nerve fibers. This allows for fast and precise communication between different parts of the body. In contrast, humoral regulation relies on the release of chemical messengers called hormones into the bloodstream, which then travel to target cells or organs. Hormonal signaling is generally slower compared to nerve impulses [[2]].

C) Faster Signal Propagation: Nerve impulses can propagate at high speeds, allowing for rapid communication between different parts of the body. The speed of nerve impulse propagation can reach up to several meters per second in some cases. This is significantly faster than the speed at which chemical signals can be transported through the bloodstream in humoral regulation. The difference in speed can be on the order of hundreds or even thousands of times faster for nerve impulses compared to chemical signaling [[3]].

In summary, the nervous system's characteristics, such as being an evolutionarily younger form of regulation, the transmission of nerve impulses, and the faster propagation of signals, suggest that it is a more progressive system of regulating the activities of the organism compared to the humoral system.
