What are the 4 main organs tissues of the nervous systems?

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 are the 4 types of nervous system?

The PNS is divided into three separate subsystems, the somatic, autonomic, and enteric nervous systems. Somatic nerves mediate voluntary movement. The autonomic nervous system is further subdivided into the sympathetic and the parasympathetic nervous systems….

What type of nervous system do humans have?

central nervous system
The human nervous system consists of two main parts: the central nervous system (CNS) and the peripheral nervous system (PNS). The CNS contains the brain and spinal cord….Peripheral nervous system.

What are the 3 major organs of the nervous system?

The Human Nervous System: The major organs and nerves of the human nervous system. The CNS is comprised of the brain, cerebellum and spinal cord. Remaining neurons, and associated cells, distributed throughout the body form the PNS.

What type of tissue is nervous tissue?

Nervous tissue is one of four major classes of tissues. It is specialized tissue found in the central nervous system and the peripheral nervous system. It consists of neurons and supporting cells called neuroglia. The nervous system is responsible for the control of the body and the communication among its parts.

What are the nervous tissues?

Nervous tissue is found in the brain, spinal cord, and nerves. It is responsible for coordinating and controlling many body activities. The cells in nervous tissue that generate and conduct impulses are called neurons or nerve cells. These cells have three principal parts: the dendrites, the cell body, and one axon.

How many nervous system are there in human body?

It is essentially the body’s electrical wiring. Structurally, the nervous system has two components: the central nervous system and the peripheral nervous system. According to the National Institutes of Health, the central nervous system is made up of the brain, spinal cord and nerves.

How many types of nerves are there in the human body?

There are three types of nerves in the body: Autonomic nerves. These nerves control the involuntary or partially voluntary activities of your body, including heart rate, blood pressure, digestion, and temperature regulation. Motor nerves.

What type of cells does nervous system contain?

The nervous system is composed of two basic cell types: glial cells (also known as glia) and neurons . Glial cells, which outnumber neurons ten to one, are traditionally thought to play a supportive role to neurons, both physically and metabolically.

How is nervous tissue different from other tissues?

Nervous tissue is composed of neurons, also called nerve cells, and neuroglial cells . Four types of neuroglia found in the CNS are astrocytes, microglial cells, ependymal cells and oligodendrocytes .

What are some examples of nervous tissue?

Examples of nervous tissue include the brain, spinal cord, and the peripheral nervous system. All of these systems regulate and control various functions in the body.

What are the types of nerve tissue?

There are two main categories of nerve tissue: that found in the central nervous system and that in the peripheral nervous system. The central nervous system is made up of tissue found in the brain and spinal cord, while the peripheral nervous system contains nerve cells, fibers,…
