What is the main difference between nervous coordination and chemical coordination?
What is the main difference between nervous coordination and chemical coordination?
- Chemical coordination relies on the brain, while nervous coordination involves the endocrine system.
- Nervous coordination only occurs in humans, while chemical coordination occurs in both plants and animals.
- Nervous coordination is slower than chemical coordination.
- Nervous coordination involves electrical signals, while chemical coordination involves the release of hormones. (correct)

Nervous Coordination
Nervous Coordination
Involves the transmission of electrical signals along nerve cells, enabling rapid and localized responses.
Chemical Coordination
Chemical Coordination
Relies on the release of chemical messengers called hormones, which travel through the bloodstream, leading to slower but widespread effects.

Study Notes
Nervous and Chemical Coordination
- Nervous coordination involves electrical impulses transmitted through neurons, whereas chemical coordination involves hormonal signals transmitted through the bloodstream.
Human Eye Anatomy
- The cone cells in the human eye are responsible for detecting color in bright light.
Insulin and Blood Glucose Regulation
- The main function of the hormone insulin is to regulate blood glucose levels by facilitating glucose uptake in cells.
- When blood glucose concentration rises, insulin is released to stimulate glucose uptake in cells, thereby reducing blood glucose levels.
Neuron Structure and Function
- The synapse is the structure responsible for transmitting nerve impulses between neurons.
Pancreatic Response to Blood Glucose Levels
- When blood glucose concentration drops below normal, the pancreas responds by releasing glucagon, which stimulates the liver to release stored glucose (glycogen) into the bloodstream.
Nervous System Disorders
- Functional disorders related to the nervous system include neuropathy, myopathy, and dystonia.
- Paralysis is a type of disorder characterized by the complete loss of function by one or more muscle groups.
Blood Glucose Levels and Diagnosis
- The normal blood glucose level after 8-10 hours of fasting is less than 100 mg/dL.
- A blood glucose level of 200 mg/dL or higher after consuming a 75-gram glucose drink indicates diabetes.
Hormonal Regulation and Feedback Mechanisms
- Testosterone is the hormone responsible for the development of male secondary sex characteristics like growth of facial hair and vocal changes.
- A negative feedback mechanism decreases or inhibits a process, such as insulin reducing blood glucose levels.
