Difference Between Nervous System and Endocrine System

One important difference between the nervous system and the endocrine system is that nerves use electricity to send signals through nerves while endocrine glands use nerves to send signals to target cells through the blood.

Difference Between Nervous System and Endocrine System

What is Nervous System?

The nervous system receives, processes and processes stored information using electrical pulses. The nervous system is the part of the body of an animal that controls behavior and communicates with other parts of the body.

The central nervous system (CNS) and the peripheral nervous system (PNS) are major components of the spinal nervous system (PNS). The brain and spinal cord reside in the CNS.

The PNS consists of nerves, which are long fibers that connect the CNS to every other part of the body, as well as peripheral ganglia, sympathetic and enteric nervous systems.

This system is a semi-independent part of the nervous system that controls… the gastrointestinal tract, and the parasympathetic nodes.

What is Endocrine System?

The endocrine system uses chemical signals to control the activity of organs and cells. These chemical signals are transmitted through the bloodstream and are called nerves.

These glands produce hormones that are then transported through the bloodstream to various parts of the body. They give signals to the body parts and tell them what to do. When glands do not produce enough hormones, diseases develop that can have many complications.

  • Respiration
  • Metabolism
  • Reproduction
  • Sensory perception
  • Movement
  • Sexual development
  • Growth

Difference Between Nervous System and Endocrine System

Nervous System Endocrine System
Electrical impulses are the messengers in the nervous system Hormones are the chemical messengers in the endocrine system that target cells through the bloodstream
Brain and the spinal cord constitute the nervous system Glands and organs like thyroid, pituitary glands and reproductive organs (ovaries and testes) are involved in the endocrine system
Nerve impulses are transmitted through neurons Hormones are transmitted through blood vessels
The nervous system is under both voluntary and involuntary control The endocrine system is under involuntary control
Nerve impulses make use of the neurotransmitters at synaptic clefts and sodium and potassium channels and enter the target cells. The hormones enter into the target cells by diffusing through the plasma membrane or by binding to the cell receptors
Responses are localised Responses are widespread
