Question

Both the nervous and endocrine systems control body functions. How are they similar and dissimilar in the way they work, types of structures served, and speed of action?

Answer 1

Answer and explanation:

The nervous and the endocrine system are fundamental to the correct functioning of the body as they regulate and coordinate all of its function - the nervous system does so by using neurotransmitters that are transported by the nerves to the places that need that stimulus, while the endocrine system has glands that produce hormones that travel through the blood in order to reach a specific destination.

They are similar in how there's an organ that controls the whole process: in the nervous system, that's the brain; in the endocrine system, that role is mostly played by the hypophysis (also called pituitary gland).

Since hormones easily travel through the blood, the endocrine system has no need for direct connections like the nervous system does. Hormones are also very specific -they only act on certain cells-, while neurotransmitters are much more ambiguous. The time that takes each stimulus to reach its destination also differs in these two systems: the nervous system is much faster than the endocrine system.

Answer 2

Answer:

Similarity

Both nervous and endocrine system are similar in a way that they perform the regulatory function in the body and act as regulator in various body functions.

Difference

1. nervous  system uses  electrical impulses (neural)for signaling while endocrine system  uses chemical signals called hormones, which travel through the bloodstream and control the actions of cells and organs.

2. The nervous system can respond quickly to stimuli, through the use of action potentials and neurotransmitters. Responses to nervous system stimulation are typically quick but short lived. The endocrine system responds to stimulation by secreting hormones into the circulatory system that travel to the target tissue.
