There are two main cell types: neurons and neuroglia. The nerve cell known as the “functional unit”. Transmits the impulses of the nervous system.
What is the main cell of the 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.
What are the cells 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 make up nervous tissue quizlet?
Nervous tissue consists of two types of cells, nerve cells or neurons, and neuroglia.
Which term is the basic cell of the nervous system?
What is a neuron? The basic functional cell of the Nervous System.
Where is nervous tissue not found?
Solution : Tendons are the connective tissue, which join skeletal muscels to bones, hence nervous tissue is absent is them .
What is nervous tissue with diagram?
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 is nervous tissue and its types?
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 3 types of nervous tissue?
There are three types of nerves in your body: autonomic nerves, motor nerves, and sensory nerves. SOURCES: National Institute of Neurological Disorders and Stroke: “NINDS Peripheral Neuropathy Information Page.” Neuropathy Association: “About Peripheral Neuropathy: Facts.”
How many types of nervous tissue are there?
Nervous tissue is grouped into two main categories: neurons and neuroglia. Neurons, or nerves, transmit electrical impulses, while neuroglia do not; neuroglia have many other functions including supporting and protecting neurons.
What is the function of the nervous system called?
Functions of the Nervous System
The nervous system has 3 main functions: sensory, integration, and motor. Sensory. The sensory function of the nervous system involves collecting information from sensory receptors that monitor the body’s internal and external conditions.
What are the general functions of the 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.
Which two types of cells make myelin quizlet?
There are two types of Schwann cell, myelinating and nonmyelinating. Myelinating Schwann cells wrap around axons of motor and sensory neurons to form the myelin sheath.
What are the two major types of cells in the nervous system?
There are two broad classes of cells in the nervous system: neurons, which process information, and glia, which provide the neurons with mechanical and metabolic support. Three general categories of neurons are commonly recognized (Peters, Palay, & Webster, 1976).
What is the most important cell in the nervous system?
Neurons are the central building blocks of the nervous system, 100 billion strong at birth. Like all cells, neurons consist of several different parts, each serving a specialized function ([link]).
What are the two major subdivisions of the nervous system?
The nervous system as a whole is divided into two subdivisions: the central nervous system (CNS) and the peripheral nervous system (PNS).
