### Neuroglia of the CNS and PNS The provided image illustrates the neuroglia of the Central Nervous System (CNS) and Peripheral Nervous System (PNS). Below is a detailed description and transcription for educational purposes. #### (a) CNS 1. **Astrocytes (AS-troh-cytes)** - These are star-shaped cells in the CNS that maintain the blood-brain barrier, provide structural support, and regulate ion, nutrient, and dissolved gas concentrations. 2. **Ependymal (ee-PIN-dih-mahl) cell** - These cells line the ventricles of the brain and the central canal of the spinal cord. They are involved in the production, circulation, and monitoring of cerebrospinal fluid. 3. **Microglial (my-CROG-lee-al) cell** - These are the primary immune defense cells of the CNS. They act as macrophages, clearing cellular debris and dead neurons through phagocytosis. 4. **Oligodendrocyte (OL-ih-go-DEN-droh-site)** - These cells provide support and insulation to axons in the CNS by forming a myelin sheath. #### (b) PNS 5. **Satellite cell** - These cells surround neuron cell bodies within ganglia, providing support and nutrients to the neurons. 6. **Schwann (shh-WAN) cell** - Schwann cells are responsible for the formation of myelin sheaths around the axons of peripheral nerves, similar to the role of oligodendrocytes in the CNS. ### Diagram Description The image is divided into two primary sections labeled (a) CNS and (b) PNS. - The CNS section shows various components including cells of the pia mater, neurons, blood capillaries, microvilli, and specific neuroglia such as astrocytes, ependymal cells, microglial cells, and oligodendrocytes. Nodes of Ranvier and myelin sheaths surrounding neurons are also depicted. - The PNS section highlights a neuron cell body within a ganglion, showcasing the position and appearance of satellite and Schwann cells with an axon extending outward. This illustration helps in understanding the differences and functions of neuroglia in both the central and peripheral nervous systems.
