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
