Coordination Between The Nervous System and The Endocrine System

14 Jan

Similarities:

(a) both respond to stimuli
(b) Coordinate the body’s activities and functions
(c) Have target organs

Differences:

The main difference between these two systems is that the nervous system co-ordinates the body through electrical impulses whereas the endocrine system also co-ordinates bodily functions but is composed of glands that excrete hormones. The nervous system controls muscle movement, senses, heartbeat, breathing, digestion, memory and speech whilst the endocrine system controls levels of glucose in the blood, hydration levels, heat productivity, sexual maturity, sperm and egg production and growth of cells and tissues.

The nervous system:
effect is localized
take shorter time to produce a reaction
duration of a reaction is shorter
do not require hormone

The endocrine system:
effect is widespread
take longer time to produce a reaction
duration of a reaction is longer
involve hormone as an organic messenger

Coordination between the nervous system and the endocrine system is very important.

This coordination :
Enable the body to carry out its activities and functions efficiently and smoothly.
Enables the body to respond to stimuli effectively so as to take action quickly and avoid injury.
Enables the nervous system to detect changes in the body or environment and relate it to the endocrine system for producing the hormones required for join response and action.
Without coordination between the nervous system and the endocrine system , the body cannot function as a whole .
