What is difference between chemical control and nervous control?
What is difference between chemical control and nervous control?
Answer Expert Verified 1) Nervous control is a very fast process whereas chemical control is a very slow process. 2) Neurons are less persistent, and chemical control is a highly persistent process. 3) Nervous control is valuable for connected cells only and chemical control is a universal process.
What is the difference between nervous and hormonal system?
Like the nervous system, hormones can control the body….Hormones and nerves.
| Nervous | Hormonal | |
|---|---|---|
| Transmission of signal | By nerve cells | By the bloodstream |
| Effectors | Muscles or glands | Target cells in particular tissues |
| Type of response | Muscle contraction or secretion | Chemical change |
| Speed of response | Very rapid | Slower |
What are three differences between the nervous and endocrine system?
Both the nervous system and endocrine system give signals to the internal body parts….Nervous System vs Endocrine system.
| Nervous System | Endocrine System |
|---|---|
| Electrical impulses are the messengers in the nervous system | Hormones are the chemical messengers in the endocrine system that target cells through the bloodstream |
Why nervous co ordination is quick as compared to the chemical coordination?
Explanation: Chemical co-ordination is maintained with help of hormones whereas neural coordination is maintained through change in membrane potential across the neurons which is done chiefly by Na+ – K+ pump. That is why neural coordination is faster than chemical coordination.
What is chemical and nervous control?
For one, the endocrine system uses chemical signaling (hormones, produced by glands) while the nervous system uses electrical signaling (neural impulses). The signal transmission of the nervous system is fast because neurons are interconnected, but the functions are more short-lived.
What is chemical control?
Chemical control is based on substances that are toxic (poisonous) to the pests involved. When chemical pesticides are applied to protect plants from pests, diseases or overgrowth by weeds, we speak of plant protection products. Then there are herbicides which are used against weeds.
What is the similarities between nervous and endocrine system?
The nervous system and endocrine system both use chemical messengers to signal cells, but each has a different transmission speed.
Is the nervous system faster than the endocrine system?
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. Responses to endocrine system stimulation are typically slow but long lasting.
What are two differences between the nervous and endocrine system?
Ans. The primary difference between nervous system and endocrine system is in nervous system electrical impulses are used, whereas the endocrine system involves chemical signal called hormones. Secondly, the nervous system is formed by a collection of neuron cells, glands and organs operate the endocrine system.
What are the steps involved in nervous coordination?
17.1: Steps Involved in Nervous Coordination (Practice Test)
- Stimuli, Receptors,Effectors, Response.
- Coordinated Action, Stimuli, Receptors.
- Coordinators and Effectors, Response.
What is meant by nervous coordination?
1. “ Nervous coordination is brought about by means Stimuli Receptors of nervous system which is the quickest way of communication CNS Effectors in the body of an animal by electro-chemical messages called nerve Response impulse.”
What is nervous system with diagram?
The Central Nervous System is the integration and command center of the body. It consists of the brain, spinal cord and the retinas of the eyes. The Peripheral Nervous System consists of sensory neurons, ganglia (clusters of neurons) and nerves that connect the central nervous system to arms, hands, legs and feet.
What is the most important part of the nervous system?
Neurons are the basic unit of the nervous system. The nervous system consists of two main parts. Peripheral Nervous System – PNS….Thank you.

Chemical control is using pesticides, fungicides and bactericides to control pests and diseases. Problems with chemical control include residues, crop damage, killing of beneficial insects and poisoning of humans and their animals.
What are 3 methods of pest control?
Biological pest control methods
- Natural predators. This method of pest control is by no means modern.
- Microorganisms. Another popular natural pest control method used by gardeners is the use of beneficial microorganisms on plants.
- Elimination of breeding grounds.
- Poison bait.
- Field burning.
- Trap cropping.
- Traps.
What are the similarities between the central and peripheral nervous system?
Both central and peripheral nervous systems are the two components of the nervous system of vertebrates. Both nervous systems are involved in responding different environmental stimuli in the environment, maintaining the life. Both nervous systems comprise neurons with the same physiology.
What are the similarities between hormones and nerves?
The basic similarities between the nervous and the endocrine systems are that they provide the body with methods to communicate with its internal and external environments in order to coordinate responses. They both employ chemicals to transmit messages and respond to stimulus caused by changes in their environments.
What are the similarities between nervous system and endocrine system?
What are the similarities between the nervous system and the endocrine system? Both the nervous system and endocrine system are devoted to maintaining homeostasis by coordinating and regulating the activities of other cells, tissues, organs, and systems. Both systems are regulated by negative feedback mechanisms.
Why do we need both endocrine and nervous system?
The endocrine system works together with the nervous system to influence many aspects of human behaviour, including growth, reproduction, and metabolism. And the endocrine system plays a vital role in emotions.
What is coordination in nervous system?
Nervous coordination involves the participation of our sense organs, nerves, spinal cord, and brain. The changes, which occurs around us can be easily detectable by our sense organs. This is because the nervous system has neurons at their tips, which consist of dendrites, cell body, nucleus, and axon.
