Dendritic cells - Study guides, Revision notes & Summaries

Chapter 2 of the document explores the structure and function of the nervous system, focusing on the fundamental roles of neurons and glial cells. It begins by discussing the differentiation of embryonic stem cells into neurons and glial cells, which provide essential support to neurons. The chapter outlines the major external features of neurons, including the soma, dendrites, and axon, and emphasizes the significance of the semipermeable membrane, mitochondria, and ATP synthesis in neuron func...
