Hormones are chemical messengers produced by glands that travel through the bloodstream to target organs, regulating various physiological processes over longer durations, such as growth, metabolism, and mood. In contrast, motor nerves are part of the nervous system that transmit electrical signals from the brain and spinal cord to muscles, facilitating immediate and precise movements. While hormones typically exert broader, slower effects on the body, motor nerves enable rapid and specific responses to stimuli.

What are differences between hormones and nerves?
Hormones are chemical messengers that travel through the bloodstream to target cells, while nerves are specialized cells that transmit electrical signals between different parts of the body. Hormones tend to have slower and longer-lasting effects, whereas nerve impulses are rapid and short-lived. Hormones are produced by glands such as the pituitary or adrenal glands, while nerves are made up of neurons that form the nervous system.
Why use nerves and hormones?
Without hormones, many functions cannot happen in your body. If you don't have hormones, you will get Diabetes. Without nerves, you cannot touch anything or feel anything.
How brain control our body?
Via voluntary nerves, via autonomic nerves, and via hormones.
What is the functional classification for voluntary nerves?
somatic motor
What controles the other body systems?
Nerves & hormones.
What is the difference between veins and nerves?
There is a big difference, both structural and functional between the veins and the nerves.Structural differences:1. The nerves are composed of nerve cells called NEURONS. A neuron is composed of the body which has NUCLEUS inside, long extension branch called AXON (which is surrounded by MYELIN in some nerves), short extension branches called DENDRITES and SYNAPTIC TERMINAL.2. A vein is a tubular organ composed of 3 layers:a) tunica externa (epithelial cells)b) tunica media (smooth muscle cells)c) tunica interna (endothelial cells)Functional differences1. The nerves function is to carry information from the receptor (f.e. skin) to the brain and from the brain to the effector (f.e. striated muscle). This is called reflexive arch.2. The definition about a vein is: a blood vessel that transports blood to the heart.Both arteries and veins are types of nerves
What is the nutrient that forms a coating on nerves?
The class of nutrient that is necessary for production of certain hormones and that forms a coating on nerves is
How do the endocrine and nervous systems work together?
Nerves tell glands when to release chemicals. Nerves send messages to glands. Apex- Nerves instruct glands to send out hormones.
Is the nerve the functional unit of the nervous system?
No. The functional unit of the nervous system is the neuron. Neurons group together to form nerves.
What is the difference between sensory nerve and motor nerves?
Sensory nerves carry impulses to the brain (as sights seen, sounds heard, etc.). Motor nerves carry impulses from the brain to cause the body to do things such as move muscles.
The class of nutrient that is necessary for production of certain hormones and that forms a coating on nerves is?
fat
How are the messages of the endocorine system moved around the body?
By blood (hormones) and nerves (autonomic).
