PDF-Structure of Myelin Sheaths in the Central Nervous System of Xenopus l

Studies on the structure of peripheral and central myelin using xray diffraction 1 2 polarised light 3 and electron microscopy 2 46 show that in both cases the myelin has the same basic st.

To sense, interpret, and respond to internal and external environmental changes to maintain a steady state in the . body (homeostasis). The nervous system is divided into two major structures: . THE CENTRAL . NERVOUS SYSTEM. The nervous system is divided into two subunits. Central nervous system . (. CNS. ) . Brain . spinal cord.. Peripheral nervous system.

In the Biology 20 course, you studied some of the major body systems in the context of achieving homeostasis.. Homeostasis. : the process by which a constant internal environment is maintained despite changes in the environment.. Chapter 6: The Nervous System. Our nervous system has the ability to simultaneously direct multiple functions taking place in in our bodies.. Two major divisions:. Central nervous system (CNS). . It directs the activity of the entire nervous system.. Brain. Spinal Cord. (also includes 4 chambers in brain called ventricles).

(CNS) AND THE PERIPHERAL NERVOUS SYSTEM (PNS) Learning objectives: The nervous system in humans is a complex integration of organs like brain, spinal cord and sensory organs along with nerves. N Figure 1. Nervous System Hierarchy Characteristics of the Central Nervous System The most fundamental way of categorizing groups of neurons that make up the central nervous system is as nuclei and synthetase in astrocytes (see Figure 10.13), glutamine isformed from glutamate. Glutamine is then uptaken byneurons and transformed back in glutamate.2.2OLIGODENDROCYTES FORM THE MYELIN SHEATHS OF AXO
