Nervous tissue the most complex of the four basic tissues, is composed of nerve cells, the neurons and supporting cells, the neuroglia. Unlike other basic tissues, the nervous tissue almost lacks intercellular substance.
What makes nervous tissue unique?
Nervous tissue is characterized as being excitable and capable of sending and receiving electrochemical signals that provide the body with information. Two main classes of cells make up nervous tissue: the neuron and neuroglia (Figure 4.5.
How is nervous tissue different?
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 difference between muscle tissue and nervous tissue?
The key difference between muscular tissue and nervous tissue is that the muscular tissue is a tissue specialized for contraction, while the nervous tissue is a tissue specialized for communication. … There are three types of muscular tissue: skeletal muscle, cardiac muscle and smooth muscle.
What 2 capabilities makes nervous tissue different from other tissues?
Integration and communication are the two major functions of nervous tissue. Nervous tissue contains two categories of cells — neurons and neuroglia. Neurons are highly specialized nerve cells that generate and conduct nerve impulses.
What are two characteristics that distinguish nerve cells from other cells?
However, neurons differ from other cells in the body because: Neurons have specialize cell parts called dendrites and axons. Dendrites bring electrical signals to the cell body and axons take information away from the cell body. Neurons communicate with each other through an electrochemical process.
What are the special features or characteristics of the nervous system?
Nervous system cells are called neurons. They have three distinct parts, including a cell body, axon, and dendrites. These parts help them to send and receive chemical and electrical signals.
What are 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.
What tissues are in 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 different types of cells 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.
Why is the main difference between muscle cells and nerve cells?
The main difference between muscle cells and nerve cells is that muscle cells are responsible for the contraction and relaxation of muscles whereas nerve cells are responsible for the coordination of the functions of the body through the transmission of nerve impulses between the body and the central nervous system.
What’s the difference between muscle cells and nerve cells?
Muscle cells are found specifically in muscles and possess the ability to shorten themselves due to the presence of motor proteins in them. Nerve cells are functional units of the nervous system. They are granular cells and help in the transmission of nerve impulses throughout the body.
How are nerve cells and muscle cells similar?
The origin of the membrane voltage is the same in nerve cells as in muscle cells. In both cell types, the membrane generates an impulse as a consequence of excitation. This impulse propagates in both cell types in the same manner.
What are the two main functions of nervous tissue?
Function Of Nervous Tissue
- Neurons generate and carry out nerve impulses. …
- Responds to stimuli.
- Carries out communication and integration.
- Provides electrical insulations to nerve cells and removes debris.
- Carries messages from other neurons to the cell body.
What two distinct cells form nervous tissue?
Nervous tissue contains two major cell types, neurons and glial cells.
