Although the nervous system is very complex, there are only two main types of cells in nerve tissue. The actual nerve cell is the neuron. It is the “conducting” cell that transmits impulses and the structural unit of the nervous system. The other type of cell is neuroglia, or glial, cell.
What is the main cell of nervous tissue called?
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. The main part of the cell, the part that carries on the general functions, is the cell body.

Which cells of nervous tissue are supporting cells quizlet?
Supporting cells, aka neuroglial cells are nonconducting cells located close to the neurons that hold nervous tissue together structurally. They establish compartments and monitor passage of materials through the tissue. You just studied 22 terms!What is the main cell of the nervous tissue What is a support cell found within nervous tissue quizlet?
Nervous tissue is composed of neurons and supporting cells called neuroglia, or ” glial cells.” There are six types of neuroglia.
What are the two major cell types found in nervous tissue?Although the nervous system is very complex, there are only two main types of cells in nerve tissue. The actual nerve cell is the neuron. It is the “conducting” cell that transmits impulses and the structural unit of the nervous system. The other type of cell is neuroglia, or glial, cell.
Article first time published onWhat is the base cell of the nervous system?
another. 3. Dendrites – are short, branching fibers that carry nerve impulses toward the cell body.
What is the main function of nerve cells?
Neurons (also called neurones or nerve cells) are the fundamental units of the brain and nervous system, the cells responsible for receiving sensory input from the external world, for sending motor commands to our muscles, and for transforming and relaying the electrical signals at every step in between.
What is a basic cell?
Cells are the basic building blocks of all living things. The human body is composed of trillions of cells. They provide structure for the body, take in nutrients from food, convert those nutrients into energy, and carry out specialized functions. … Cells have many parts, each with a different function.
What are the tissues of the nervous system?
Structure. 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. Two types of neuroglia found in the PNS are satellite cells and Schwann cells.
What are the 4 main functions of the nervous system?
- Control of body’s internal environment to maintain ‘homeostasis’ An example of this is the regulation of body temperature. …
- Programming of spinal cord reflexes. An example of this is the stretch reflex. …
- Memory and learning. …
- Voluntary control of movement.
Do nerve cells have cell membranes?
Cells of the nervous system, called nerve cells or neurons, are specialized to carry “messages” through an electrochemical process. … Neurons are similar to other cells in the body because: Neurons are surrounded by a cell membrane. Neurons have a nucleus that contains genes.
What are the 4 types of cells?
- Epithelial Cells. These cells are tightly attached to one another. …
- Nerve Cells. These cells are specialized for communication. …
- Muscle Cells. These cells are specialized for contraction. …
- Connective Tissue Cells.
What is the blood brain barrier?
The blood-brain barrier (BBB) is a crucial immunological feature of the human central nervous system (CNS). … The BBB also exists at other intersections of the CNS and periphery, including between blood and cerebrospinal fluid-producing cells. Its purpose is to protect and regulate the brain’s microenvironment.
What is spiral cord?
The spinal cord is a long bundle of nerves and cells that extends from the lower portion of the brain to the lower back. It carries signals between the brain and the rest of the body.
What is Neuroglia Class 11?
Hint: Neuroglial cells are specialized cells found in the brain and spinal cord supporting the neurons of both CNS and PNS and their fibers. Most of the cells in the glial system are the products of the neural crest. Complete answer: About 50% of all brain cells are neuroglial cells.
Which cells in the nervous tissue support and protect the cells that conduct action potentials?
Terms in this set (6) – Nervous tissue consists of neurons, which are responsible for its conductive ability, and support cells called neuroglia.
Are the supporting cells found in nervous tissue quizlet?
Glial cells. Provide a supportive scaffolding for neurons, cover all non-synaptic parts of the neurons.
What is the basic cell in nervous tissue it is responsible for the majority of the functions of the tissue including surroundings and conducting electrical impulses?
Nervous tissue is composed of two types of cells, neurons and glial cells. Neurons are the primary type of cell that most anyone associates with the nervous system. They are responsible for the sensory, integrative, and motor functions of the nervous system.
What is the general term for supporting cells of the nervous system?
Support cells are also called. Schwann cells. A type of support cell that surrounds all axons in the PNS. myelination.
What is the function of the Neuroglial cells in nervous tissue?
Glia or Neuroglia* The neuroglia are a diverse class of cells that provide developmental, physiological, and metabolic support for neurons. They are responsible for maintaining homeostatic control and immune surveillance in the nervous system.
What are the supporting cells in the central nervous system called quizlet?
Terms in this set (60) What are the supporting cells in the central nervous system called? A ganglion is a collection of nerve cell bodies outside of the CNS. Neuroglia are the supporting cells in the central nervous system Sometimes, neuroglia called glial cells or glia.
What are the 3 types of nervous tissue?
- Neuroglia.
- Astrocytes.
- Microglial Cells.

What are the two major cell types?
There are two main types of cells: prokaryotic cells and eukaryotic cells. Prokaryotic cells include bacteria and archaea. Prokaryotes—organisms composed of a prokaryotic cell—are always single-celled (unicellular). Prokaryotic cells don’t contain a nucleus.
What does a nerve cell consists of?
The basic unit of communication in the nervous system is the nerve cell (neuron). Each nerve cell consists of the cell body, which includes the nucleus, a major branching fiber (axon) and numerous smaller branching fibers (dendrites).
What is cell class8?
The cell is the basic structural and functional unit of life. All living organisms are made up of cells. Cells make tissues, tissues make organs, organs make organ systems and organ systems make a living organism. Thus, the cell is the building block, or the structural unit of the living body.
What are cells for kids?
The cell is the smallest unit with the basic properties of life. Some tiny organisms, such as bacteria and yeast, consist of only one cell. Large plants and animals have many billions of cells. Human beings are made up of more than 75 trillion cells.
