Myelin is present in the central nervous system (CNS) and peripheral nervous system (PNS); however only the central nervous system is affected by MS. CNS myelin is produced by special cells called oligodendrocytes.PNS myelin is produced by Schwann cells.The two types of myelin are chemically different, but they both perform the same function â to promote efficient transmission of a nerve impulse along the axon.ach neuron is made up of a cell body and an axon (the extension of the cell body that carries messages).

Mission Cables, which makes accessories for Roku and Chromecast, thinks Echo owners want to unleash Alexa from their kitchen counters and bring the speaker along to the garage, garden, and patio. The Battery Base fits over the bottom of the Echo, sort of like a beer cozy, and powers the device for six hours. That means you can unplug your Echo and take it to any of the aforementioned locations and play music (via Bluetooth) or ask Alexa for gardening tips (provided thereâs still a Wi-Fi or hot spot connection). Afterwards, youâll need to recharge the Battery Base for 90 minutes before using it again. If the Echo is your only Bluetooth speaker, we can understand why youâd want to take it with you sometimes, like if youâre hanging with friends on your patio.
