Nervous tissue is a group of specialized cells that serve to transport information in the body. Nerve cells are found throughout the body and are made up of a cell membrane that covers a nucleus and cytoplasm. The cytoplasm contains the organizers of the nerve impulse, which are the neurofilaments.
Nerve cells are divided into two main groups: neurons and glial cells. Neurons are the cells responsible for transporting information, while glial cells serve to protect and nourish neurons.
Neurons are further divided into three types: sensory neurons, motor neurons, and interneurons. Sensory neurons receive information from outside the body through sensory receptors. Motor neurons send nerve impulses to muscles or glands, causing them to move or secrete. Interneurons are located in the central nervous system and serve to interconnect other neurons.
The nervous system consists of the brain, spinal cord, and peripheral nerves. The brain is the central organ of the nervous system and consists of the cerebrum, cerebellum, and brain stem. The spinal cord is a cord of nervous tissue located in the spinal column. Peripheral nerves are nerve fibers that connect the central nervous system to the rest of the body.

What is nervous tissue Wikipedia?
Nervous tissue is a set of specialized cells that allow the transmission of nerve impulses and the coordination of body activities. The nervous system consists of the brain, brain stem, peripheral nerves, and sensory organs.
What is nervous tissue and how is it composed?
Nervous tissue is a structure that is composed of nerve cells (neurons) and supporting cells (glia). Neurons are specialized cells that conduct nerve impulses, while supporting cells serve to protect and maintain neurons. Nervous tissue is divided into the central nervous system (CNS) and the peripheral nervous system (PNS). The CNS is composed of the brain and spinal cord, while the PNS is composed of peripheral nerves.
What is the nervous system and what is its function?
The nervous system is a set of organs and tissues that allow animals to perceive the world around them and respond to stimuli. In vertebrates, the nervous system is made up of the brain, the cerebrum, and the spinal cord. The functions of the nervous system are very varied, but in general they can be divided into three: the reception of stimuli, the integration of information, and the response.
What is the organ of nervous tissue?
The organ of nervous tissue is the brain, which is located in the skull. The brain is made up of several parts, including the cerebrum, the cerebellum, and the brain stem. These structures are responsible for controlling the physiological, motor, and cognitive functions of the body.
What is nervous tissue?
Nervous tissue is one of the three main categories of tissue in the human body. Nervous tissue is made up of cells called neurons, which transmit messages from one part of the body to another.
What are the functions of nervous tissue?
Nervous tissue is a specialized type of tissue that is made up of nerve cells, or neurons. Neurons are responsible for receiving, processing, and transmitting information in the form of electrical impulses. These electrical impulses travel through neurons and allow the body to respond to stimuli in the environment.
How is nervous tissue structured?
Nervous tissue is made up of cells called neurons and non-nervous cells called glia. Neurons are responsible for receiving, transporting, and sending information throughout the nervous system. Glia have a supporting function and insulate neurons from each other.
How does nervous tissue work?
Nervous tissue is made up of cells called neurons. Neurons have a cell body, a nucleus, and a long projection called an axon. Axons carry nerve impulses (messages from the brain) and are covered in a substance called myelin, which speeds up the passage of nerve impulses. Neurons are connected to each other by extensions called dendrites.
