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 2 types of cells found in the nervous system and what does each do?
Cells of 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.
What are the two types of cells in the nervous system quizlet?
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 are 2 divisions of the autonomic nervous system?
Structure and Function
- Sympathetic Nervous System.
- Parasympathetic Nervous System.
- Enteric Nervous System (ENS)
What do glia cells do?
Primarily, glial cells provide support and protection to the neurons (nerve cells), maintain homeostasis, cleaning up debris, and forming myelin. They essentially work to care for the neurons and the environment they are in.
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.
Which are cells of the central nervous system?
The central nervous system (CNS) is now thought to consist of three main cell types: neurons, glial cells and vascular cells.
What are the two major characteristics of nervous tissue?
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 the two divisions of the autonomic nervous system quizlet?
The two major divisions of the autonomic nervous system are the sympathetic division and the parasympathetic divi- sion.
What is the autonomic nervous system made up of?
The autonomic nervous system is the division of the peripheral nervous system that carries motor information to the visceral organs and glands. It is made up of the sympathetic and parasympathetic autonomic nervous systems.
What are the 4 types of glial cells?
The total glial cell population can be subdivided into four major groups: (1) microglia, (2) astrocytes, (3) oligodendrocytes, and (4) their progenitors NG2-glia.
What are two roles of glial cells quizlet?
The glial cells are equally important because they provide support, compose the myelin sheath, bring nutrients to neurons, and they clean up environment around the neurons.
What do motor nerve cells do?
Motor neurons of the spinal cord are part of the central nervous system (CNS) and connect to muscles, glands and organs throughout the body. These neurons transmit impulses from the spinal cord to skeletal and smooth muscles (such as those in your stomach), and so directly control all of our muscle movements.
