The best way to compare the nervous system and the endocrine system is to compare the characteristics of speed, specificity and plasticity (ability to respond and change permanently, particularly with respect to strength and speed.) The nervous system uses rapid electrical signals along nerve axons. Chemical signals are used between nerve cells at synapses. Although this chemical transmission is slower than electrical transmission, synapses are important in transmission between nerve cells. The endocrine system uses hormones, which are secreted into and transported to their target cells via the circulation of blood. Due to the delay of circulation, hormonal responses are generally slower than nervous response. Both systems involve diffusion (either diffusion out of blood and into tissue or diffusion across a synapse). However, the diffusion distances in synapses is considerably smaller in nervous communication so further increasing its speed over hormonal communication. The nervous system is not considered as specific as the endocrine system, with the nervous system supplying group of tissues or organs. For example, one motor neurone induces and effect of several muscle fibers. Organs such as skeletal muscle, smooth muscles and glands are targeted individually. Due to receptor sites on target cells, the endocrine system is able to be very specific is binding specifically to the appropriate cells. The nervous system is more associated with plasticity. Synaptic plasticity results in changes in the quantity of neurotransmitter released and how effectively the postsynaptic cells respond to the neurotransmitter. Although the effects of hormones are generally more permanent, the system is considered more elastic than plastic (changing but then returning to the original.) In conclusion, the body often combines the speed of the nervous system with the specificity of the endocrine system to create the neuroendocrine system. Neuroendocrine cells receive neurally transmitted information and release hormones in response which is carried via blood the the target cells. The neuroendocrine system is mainly organised by the hypothalamus.

What system regulates the body's metabolism growth and functions of the sexual organs?
The Endocrine System.
What system produces chemical signals hormones?
endocrine system
Which body system involves hormones?
The endocrine system.
System that consists of glands that secrete hormones?
The Endocrine System.
What body system manufactures hormones to regulate organ activity?
The endocrine system creates hormones and the glands of the system release them into the body.
Which system controls the endocrine system?
Endocrine is the correct answer for Apex
What human body system sends signals to glands in the endocrine system to release hormones?
what turns the endocrine on and what turns endocrine of
Is the endocrine system voluntary or involuntary?
The endocrine system is involuntary. A person cannot control the endocrine system by will.
What system regulates the body's metabolism growth and functions of the sexual organs?
The Endocrine System.
What system produces chemical signals hormones?
endocrine system
Which body system involves hormones?
The endocrine system.
What system sends out chemical messages?
The endocrine system
Is endocrine good or bad?
The endocrine system is a vital human organ system. In that sense, the endocrine system is good.
Is the endocrine system considered anatomy or physiology?
The endocrine system is an organ system. When studying the parts of the endocrine system and their structure, you are studying anatomy. When studying how the endocrine system works, you are studying physiology.
What system controls the the female reproductive system?
endocrine
What regulatory system controls the endocrine system?
The endocrine and nervous systems control the endocrine system. Messages from these systems cause the endocrine glands to change their production of hormones.
What are the effector tissues of the endocrine system?
The effector tissues of the endocrine system are the endocrine glands. Messages from the endocrine and nervous system cause these glands to alter production of hormones.
