A fundamental similarity between nervous and hormonal system is that both
A
involve chemical transmission
B
have widespread effects
C
shed chemicals into the blood stream
D
evoke rapid responses
medium Difficulty
Verified Correct Answer: Option A
Biological Concept & Syllabus Guide
The fundamental similarity between the nervous and hormonal systems is that they both use chemical signals to communicate and coordinate bodily functions. The nervous system uses neurotransmitters to transmit signals rapidly through nerve impulses, while the hormonal system uses hormones to transmit slower, more general signals throughout the body via the bloodstream. Both systems contribute to maintaining homeostasis and regulating various physiological processes.
Chemical transmission is a fundamental similarity between the nervous and hormonal systems. Both systems utilize chemicals to transmit signals, but they differ in the type of chemical and the method of transmission.
