What system controls the body with electrical signals?
the nervous systemThe signals sent by the nervous system are electrical signals called nerve impulses, and they are transmitted by special nervous system cells named neurons, or nerve cells, like the one in Figure 11.2.
What are the two control systems of our body?
The nervous system is comprised of two major parts, or subdivisions, the central nervous system (CNS) and the peripheral nervous system (PNS). … The brain is the body’s “control center.” The CNS has various centers located within it that carry out the sensory, motor and integration of data.
What are the four control systems in the body?
Describe the nervous, endocrine, reproductive, and sensory systems.
How does the nervous system control the body?
It is through the nervous system that we communicate with the outside world and, at the same time, many mechanisms inside our body are controlled. The nervous system takes in information through our senses, processes the information and triggers reactions, such as making your muscles move or causing you to feel pain.
What is the main function of the muscular system?
The muscular system is composed of specialized cells called muscle fibers. Their predominant function is contractibility. Muscles, attached to bones or internal organs and blood vessels, are responsible for movement. Nearly all movement in the body is the result of muscle contraction.
Which body parts are protected by your bones?
Although they’re very light, bones are strong enough to support our entire weight. Bones also protect the body’s organs. The skull protects the brain and forms the shape of the face. The spinal cord, a pathway for messages between the brain and the body, is protected by the backbone, or spinal column.

What gives your body its shape?
Bones provide support for our bodies and help form our shape. Although they’re very light, bones are strong enough to support our entire weight. Bones also protect the organs in our bodies. The skull protects the brain and forms the shape of the face.
What are the two main nervous systems?
The nervous system has two main parts:The central nervous system is made up of the brain and spinal cord.The peripheral nervous system is made up of nerves that branch off from the spinal cord and extend to all parts of the body.

What are the 3 main functions of nervous system?
The nervous system has three broad functions: sensory input, information processing, and motor output. In the PNS, sensory receptor neurons respond to physical stimuli in our environment, like touch or temperature, and send signals that inform the CNS of the state of the body and the external environment.
