Study Notes
Nerve Tissue
- Nerve tissue is 10 times more abundant than neurons consisting of neuroglia cells.
Learning Objectives
- Students will be able to classify neuroglia.
- Students will be able to identify neuroglia cells based on their location.
- Students will be able to describe the structure of neuroglia.
- Students will understand the function of each neuroglia in relation to its structure.
Types of Neuroglia
-
Astrocytes: Star-shaped glial cells with radiating processes. Two types:
- Fibrous astrocytes: few, long, and relatively straight processes.
- Protoplasmic astrocytes: many, short, and branching processes
- Function:
- Participate in the formation of the blood-brain barrier (BBB)
- Provide structural support
-
Oligodendrocytes: Glial cells responsible for the myelination of nerve fibers within the central nervous system (CNS). One oligodendrocyte can myelinate several nerve fibers.
-
Microglia: Small glial cells with short, irregular processes.
- Common throughout the nervous tissue.
- Mobile cells; migrate throughout the tissue, scanning for damaged cells and microorganisms.
- Phagocytic cells of the nervous tissue.
-
Ependymal cells: Cuboidal cells lining the central canal of the spinal cord and the brain ventricles.
- Secrete cerebrospinal fluid (CSF)
-
Schwann cells: Glial cells responsible for myelination of nerve fibers in the peripheral nervous system (PNS). One Schwann cell can myelinate a short segment of one axon compared with oligodendrocytes.
-
Satellite cells: Often called capsular cells, these cells form a covering layer around neuronal cell bodies in ganglia. -Provide supportive, nourishing, insulating and regulating micro-environment for the neuron.
