Question

Compare and contrast nervous and hormonal mechanisms for control and coordination in animals.

Accepted Answer

Feature Nervous Control Hormonal Control

Relies on: Nervous control relies on the generation of electrical impulses and their conduction to bring about a suitable response. Hormonal control relies on the release of hormones which act on the effector organs to bring about the response.

Feature Nervous Control Hormonal Control

Transported through Nerve impulses are transported through neurons. Hormones are transported through the blood.

Feature Nervous Control Hormonal Control

Response The response is produced quickly. The production of response is slower.

Feature Nervous Control Hormonal Control

Effect The effect is transient and vanishes as soon as the response is generated. The effect of hormones is prolonged.
