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 does nervous tissue contain?
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 is an example of nervous tissue?
Nervous tissue is found in the brain, spinal cord, and nerves. … Nervous tissue also includes cells that do not transmit impulses, but instead support the activities of the neurons. These are the glial cells (neuroglial cells), together termed the neuroglia.
How many types of nervous tissue are there?
Nervous tissue is composed of neurons and supporting cells called neuroglia, or ” glial cells.” There are six types of neuroglia. Four are found in the central nervous system, while two are found in the peripheral nervous system.
Which organ is formed by nervous tissue?
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 four tissues organized into?
Although there are many types of cells in the human body, they are organized into four broad categories of tissues: epithelial, connective, muscle, and nervous.
What are the characteristics of nervous tissue?
Characteristics of Nervous Tissue
- Nervous tissue compensates for nervous system CNS and PNS.
- Contains two different cells – neurons and glial cells.
- It consists of dendrites, ends of the cell body, axons, and nerves.
- The neurons secrete chemical neurotransmitters that stimulate other neurons as a result of stimuli.
