Study Notes
Nervous Tissue Overview
- Nervous tissue is composed of neurons and neuroglia.
- Neuroglia are 10 times more abundant than neurons.
- Neuroglia perform various functions, including maintaining the blood-brain barrier, providing structural support, regulating ion levels, and removing waste products.
Learning Objectives
- Classify neuroglia based on function and location
- Identify neuroglial cells based on their location
- Understand the structure of neuroglia in relation to their function
- Describe the function of each neuroglia
Neuroglia Classification
- Neuroglia in the central nervous system (CNS):
- Astrocytes (Protoplasmic and Fibrous)
- Oligodendrocytes
- Ependymal cells
- Microglia
- Neuroglia in the peripheral nervous system (PNS):
- Schwann cells
- Satellite cells
Astrocytes
- Star-shaped glial cells with many radiating processes.
- Two types: fibrous and protoplasmic.
- Function:
- Participate in blood-brain barrier formation
- Provide structural support.
Oligodendrocytes
- Small glial cells responsible for myelination in the CNS.
- One oligodendrocyte can myelinate multiple nerve fibers.
Microglia
- Small glial cells with short irregular processes.
- Common throughout nervous tissue.
- Mobile phagocytic cells that remove damaged cells and microorganisms.
Ependymal Cells
- Cuboidal cells lining the central canal of the spinal cord and brain ventricles.
- Produce and circulate cerebrospinal fluid (CSF).
Schwann Cells
- Glial cells responsible for myelination in the PNS
- One Schwann cell myelinates a single axon segment.
Satellite Cells
- Surround neuronal cell bodies in ganglia
- Provide supportive, nourishing, insulating and regulating microenvironment for the neurons.
Nervous Tissue Organization
- Diagram illustrating the distribution of neuroglia in the central and peripheral nervous systems shows how the different types of neuroglia are found in specific locations.
