Nerve impulses are far faster then responses to hormones. Nerve impulses involve the depolarization of neural membranes, which is as simple as the movement of sodium and potassium ions through channels. This is very very fast. The time this takes to happen is the time from when something touches you, such as your finger touching a keyboard to the time it takes you to feel that your finger is touching the keyboard. Another example of the speed of a nerve impulse is if you have ever accidentally touched a hot element on the stove, or a hot bowl and how fast your hand recoils. A nerve impulse must travel to the brain and back down again to tell your arm muscles to contract and move from the heat. This impulse is followed by a very brief period of non responsiveness but then the membrane repolarizes and the system can fire again. This whole process takes such a small time one could not measure it without special instruments
A hormonal response is slower and longer lasting. A signal must be sensed for a hormonal response, this could be anything from high or low sugar in the blood stream, to stress. Upon receiving this signal the hormone must be made. This is a time consuming event, as must hormones are proteins they must be transcribed and translated from DNA and appropriately processed in the hormone molecule. From here the hormone is transported into the bloodstream where it is distributed throughout, even though it may only act on certain areas, this is another time consuming process. For reference it takes the heart about 1 minute to completely circulate all the blood in the system, much longer then the fractions of seconds needed for nerve impulses. Once the hormones reaches its proper tissue it has its effect, which in most cases is a long and complex pathway, which can be turned on for a long period of time given that low concentrations of hormone can activate the pathway. Also another signal is also needed to counteract the effect of the pathway and turn it off. An example of this is adrenaline in a stressful situation, think back to a time where you nearly crashed your car, or went on a crazy ride at an amusement park, or something like that, the feeling of being on high afterwards is due to release of adrenaline also called epinephrine. The feeling does not occur instantly, but is still relatively fast and the feeling lasts well after the situation is over. Insulin in the blood stream is another hormonal response. When glucose is in high concentration in the blood insulin is secreted and travels through the bloodstream, it causes cells to have more glucose transporter at their surface so the high amount of glucose in the blood can move into cells and be used or stored. This is also a seemingly needlessly complex pathway involving at last 8 different reactions involving phosphorylation of proteins and lipid molecules, which certainly takes longer then the motion of ions through a channel.

How are hormones different from neurotransmitters in terms of their functions and modes of communication within the body?
Hormones and neurotransmitters are both chemical messengers in the body, but they have different functions and modes of communication. Hormones are released into the bloodstream by endocrine glands and travel throughout the body to target cells, affecting various processes like growth, metabolism, and reproduction. In contrast, neurotransmitters are released by neurons in the nervous system and act locally at synapses to transmit signals between nerve cells. Hormones have slower and longer-lasting effects, while neurotransmitters have faster and more immediate effects.
What hormones act as hormones and neurotransmitters?
Epinephrine & Norepinephrine (NE)
A major difference between neurotransmitters and hormones is that hormones reach their destination via?
blood
What are the instructons for a cell called?
Neurotransmitters, enzymes or hormones
How are hormones and neurotransmitters similar?
they both communicate stuff in the body
How do neurotransmitters differ from hormones in terms of their functions and modes of action within the body?
Neurotransmitters are chemical messengers that transmit signals between nerve cells, while hormones are chemical messengers that regulate various bodily functions. Neurotransmitters act locally at synapses, while hormones travel through the bloodstream to target cells.
What does hormones and neurotransmitters not have in common?
They are both from different systems. Hormones are from the endocrine system and neurotransmitters are from the nervous system. They both also have different ways of how they communicate with the body to change or have a reaction. Hormones travel through the blood to the location that needs to be changed or balanced. Neurotransmitters travel along nerves. A third thing is that they affect the body differently. Hormones affect the systems that we generally don't notice, like our growth. Whereas neurotransmitters our typically immediately noticed, like tickling or pain.
How do hormones and neurotransmitters work together in the body to regulate various physiological processes?
Hormones and neurotransmitters work together in the body to regulate physiological processes by communicating messages between cells. Hormones are chemical messengers released by glands into the bloodstream to target specific organs, while neurotransmitters are released by nerve cells to transmit signals between neurons. Both hormones and neurotransmitters bind to receptors on target cells, triggering a response that helps regulate processes such as growth, metabolism, and mood.
How are neurotransmitters and hormones different in terms of their functions and modes of action within the body?
Neurotransmitters are chemicals that transmit signals between nerve cells, while hormones are chemicals that regulate various bodily functions by traveling through the bloodstream. Neurotransmitters act quickly and have localized effects, while hormones act more slowly and have widespread effects throughout the body.
