The endocrine and nervous systems are both regulatory systems that help in allowing communications from different parts of the human body.
Key Takeaways
- The endocrine system secretes hormones while the nervous system transmits electrical impulses.
- The endocrine system has a slower response time than the nervous system, but its effects last longer.
- The nervous system is responsible for immediate responses to stimuli, while the endocrine system regulates long-term changes.
Endocrine System vs Nervous System
The difference between the endocrine system and the nervous system is that the signal is sent to the neurons of the brain through electrical impulses or signals of the body in a nervous system, and on the other hand, the signal is sent to the targeted cell of the body through blood streaming in the body by acting like a chemicals messenger by the endocrine system.
The system where glands in the human body produce and act like a chemical messengers, which are called hormones that result in sending signals to the target cell of the body, is known as the endocrine system in the human body.
The system that sends signals to the body through nerve impulses is known as the nervous system. The brain, spinal cord, and many more organs of the body come under the nervous system.
Comparison Table
| Parameters of Comparison | Endocrine System | Nervous System |
|---|---|---|
| Messengers | The chemical messengers in this system are hormones. | The messengers in this system are the nerve impulses. |
| Organs present | The different types of glands present in the human body are the organs present in this system. | The brain and spinal cord are the main organs in this system of the human body. |
| Cells | The cells in this system include the nerve cell neuron cell, Schwan cell, and the glial cell. | The cells in this system include the epithelial cell. |
| Effect | The effect is widespread on the body. | The effect is localized in the human body. |
| Transmission | The transmission happens through blood vessels in this system. | The transmission in this system happens through nerve cells. |
What is Endocrine System?
Each gland produces at least one secretion in an endocrine system, which later forms an organ. The adrenal gland is an example of the endocrine system that secretes adrenaline and cortisol.
The glands found in the human body’s brain area are called the pituitary gland and pineal gland. These glands secrete a kind of hormone that helps trigger the brain to send messages to the body.
In the neck region, the thyroid gland and parathyroid gland are found, which are continuous by the pancreatic gland and the adrenal gland, both found in the abdomen of the human body.
What is Nervous System?
In a nervous system, the process of its working is in such a way that from the brain, the impulses are travelled to the spinal cord, after which the messages are interpreted in the human body.
This helps create a nerve input that helps send and receive messages. The spinal cord and the brain are attached at a point. This point in the human body is known as the posterior region.
The nervous system is divided into the central nervous system and the peripheral nervous system. When a particular message in the body is transmitted as nerve impulses, it is said to be known as the action potential.
Main Differences Between Endocrine System and Nervous System
- The effect of the endocrine system is widespread in the human body; on the other hand, the effect of the nervous system is localized in the human body.
- Transmission is an endocrine system that happens through blood vessels, and on the other hand, transmission in a nervous system happens through nerve cells.
