Question

How do nerves and hormones control the body's actions?

Answer 1

Hormones are chemical messengers in a body that are secreted directly into the blood, which carries them to organs and tissues of the body to make them to do their functions. There are many types of hormones that act on different aspects of bodily functions and processes.

Complete answer:
Neurons are the structure squares of the body's correspondence framework, it is the organization of neurons that permit signs to move between the cerebrum and body. These coordinated organizations, made out of up to 1 trillion neurons, make up what is known as the sensory system.

The system through which hormones control the body functions is called the endocrine system.
Hormones are the chemical messengers in the endocrine system that target cells through the bloodstream. Glands and organs like thyroid, pituitary glands and reproductive organs (ovaries and testes) are involved in the endocrine system. Hormones are transmitted through blood vessels.
The endocrine system is under involuntary control. Responses are widespread in the endocrine system.

In nervous system electrical impulses are the messengers.Brain and the spinal cord constitute the nervous system.Nerve impulses are transmitted through neurons. the nervous system is under both voluntary and 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 In nervous system

Note: Nervous system is responsible for the physical movement in body while endocrine system is responsible for the chemical changes in body and physical changes in body.
