Nervous control is faster than hormonal action because it relies on electrical impulses transmitted through neurons, allowing for immediate responses to stimuli. This rapid communication enables quick reflexes and coordination of bodily functions. In contrast, hormonal action involves the release of hormones into the bloodstream, which takes more time to reach target cells and elicit a response, resulting in slower physiological changes.

What advantage does the nervous system have over the endocrine system?
The messages of the nervous system are relayed by nervous impulses, which are very fast and short-acting. In contrast, the messages of the endocrine system are sent via chemical messengers (hormones) distributed by the circulatory system. This distribution in your blood is much slower than the electrical impulses of the nervous system.
What is the differences between hormonal and neural control of the body functioning?
The nervous system regulates the activity of muscles and glands via electrochemical impulses delivered by neurons, and those organs respond within milliseconds. The endocrine system influences metabolic activity by means of hormones, which are chemical messengers released into the blood to be transported throughout the body. Binding of a hormone to cellular receptors initiates responses that typically occur after a lag period of seconds or even days. The responses tend to be much more prolonged than those induced by the nervous system.
How do the nervous system and the endocrine system differ in their control of body activities?
Speed and duration. Nerves are faster, hormones last longer.
Does the endocrine system work faster than the nervous system?
nope. nervous system is much faster.
WHAT AUTONOMIC NERVOUS SYSTEM INCREASE HEART RATE?
The autonomic nervous system that increases heart rate is the sympathetic nervous system. When activated, it releases neurotransmitters like norepinephrine, which stimulate the heart to beat faster and with greater force. This response is part of the body's "fight or flight" mechanism, preparing it for quick action. In contrast, the parasympathetic nervous system works to decrease heart rate.
What type of cell enhances the velocity of electrical transmission of an action potential along an axon in the peripheral nervous system?
Schwann cells enhance the velocity of electrical transmission of an action potential along an axon in the peripheral nervous system by forming a myelin sheath around the axon. This myelin sheath insulates the axon, allowing for faster conduction of the action potential through a process known as saltatory conduction.
Which is faster Endocrine function compared to nervous function?
Nervous is much faster. Impulse transmission happens in mSecs to seconds, hormones are usually agonists of nuclear receptors, and affect gene transcription, which takes hours to days to take full effect.
What does Salutatory conduction of an action potential mean?
Saltatory conduction refers to the process by which action potentials jump between the nodes of Ranvier along myelinated axons. This occurs because the myelin sheath, produced by oligodendrocytes in the central nervous system and Schwann cells in the peripheral nervous system, insulates the axon, allowing electrical impulses to travel faster. As the action potential reaches a node, it triggers depolarization, which then rapidly propagates to the next node, enhancing the speed and efficiency of signal transmission in neurons.
What is the organ that enables heart beat faster when you exercise?
The nervous system causes the heart to beat faster when you exercise. It itself is not an organ but a system.
How does exercise help your nervous system?
helps you keep up and move faster with workout
What can help the nervous system?
Keep healthy so the nerves would go faster
Why does blood pressure increase?
The answer to this is very simple. When you get nervous,your blood pressure starts to increase. A player is always nervous before a game. They are nervous because they don't know if they will win or lose.
