Question

compare and contrast nervous And hormonal mechanism for control and coordination in animal

Answer 1

Hi.....


Here's the answer to your question...

Nervous control || Hormonal Control

It consists of nerve impulses between PNS, CNS and Brain. 1 It consists of endocrine system which secretes hormones directly into blood.

Here response time is very short. 2 Here response time is comparably long.

Nerve impulses are not specific in their action. 3 Each hormone has specific actions.

The flow of information is rapid. 4 The flow of information is slower as compared to nervous control.

Hope this helps you....

Please mark as the brainliest answer.

Answer 2

Nervous mechanism:-

1. It is performed by nervous system which sent an electrical impulse along axons and as a chemical across synapse and acts through effectors.

2. The information is transmitted instantaneously.

3. the effects are short lived.

Hormonal mechanism:-

1. It is performed by chemical sub. called hormones , secreted by endocrine glands.

2. the information is transmitted slowly not as fast as nervous mechanism.

3. the effects are generally more prolonged.
