Which organs make up the nervous system?
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 different types of nervous systems?
What is the nervous system?
- Central nervous system. This consists of the brain and spinal cord.
- Peripheral nervous system. This consists of all other neural elements, including the peripheral nerves and the autonomic nerves.
What is nervous system with diagram?
The Central Nervous System is the integration and command center of the body. It consists of the brain, spinal cord and the retinas of the eyes. The Peripheral Nervous System consists of sensory neurons, ganglia (clusters of neurons) and nerves that connect the central nervous system to arms, hands, legs and feet.
Why is the nervous system the most important system in our body?
The human nervous system is responsible for coordinating every movement and action your body makes. More importantly, it controls every function inside the human body as well. For your heart to beat, your lungs to breath, and your feet to walk, your nervous system must be functioning properly.
What is nervous system of human body?
Human nervous system, system that conducts stimuli from sensory receptors to the brain and spinal cord and conducts impulses back to other parts of the body.
What is the major function of our nervous system?
The nervous system is the major controlling, regulatory, and communicating system in the body. It is the center of all mental activity including thought, learning, and memory. Together with the endocrine system, the nervous system is responsible for regulating and maintaining homeostasis.
What are the 5 main parts of the nervous system?
The nervous system consists of the brain, spinal cord, sensory organs, and all of the nerves that connect these organs with the rest of the body. Together, these organs are responsible for the control of the body and communication among its parts.
What is the main function of nervous system?
What makes up the nervous system of the body?
The nervous system is the information processing and communications network of the body. It includes all the nerves, the sensory organs, the spinal cord, and the brain. However, the nervous system is separated into two different categories known as the central nervous system and the peripheral nervous system.
How many organ systems are there in the human body?
There are eleven organ systems in the human body. All of these are required for survival, either of the person or of the species. When we think of—and speak about—the circulatory system, we are usually talking about the cardiovascular system, which includes the heart and blood vessels (arteries and veins), as well as the blood itself.
How many neurons are in the human brain?
The human brain contains about 100 billion neurons. A neuron has a cell body, which includes the cell nucleus, and special extensions called axons (pronounced AK-sonz) and dendrites (pronounced DEN-drahytz ). Bundles of axons, called nerves, are found throughout the body. Axons and dendrites allow neurons to communicate, even across long distances.
What are the functions of the central nervous system?
The central nervous system (CNS) controls most functions of the body and mind. It consists of two parts: the brain and the spinal cord. The brain is the center of our thoughts, the interpreter of our external environment, and the origin of control over body movement. Consequently, what protects the organs of the central nervous system?
