Compbelli Biolosy Chapters 48 , 49.1 1. How does information flow in the nervous system? How is the nervous system organized? What are the two major divisions of the nervous system? What types of neurons is each composed of? What are the two branches of the peripheral nervous system (PNS)? What are the two branches of the efferent PNS? What are the two major branches of the autonomic system? 2. What are the two basic types of cells that constitute the nervous system? What functions do they perform? Give examples of each. What glial cells did we discuss and what functions do they perform? What are the three basic structural parts of a neuron? What are their functions? What is a nerve? How is it different from a neuron? 3. What is a synapse? What roles to the presynaptic and postsynaptic cells play in signal transmission? What type of cels can be presynaptic? Postsynaptic? What roles do neurotransmitters play in this process? What cells (pre/postsynaptic) release them? Detect them? 4. What gradients exist for sodium and potassium in a neuron? Which direction are they? What established these chemical gradients? What is an equilibrium potential (E Eumi? What equilibrium potentials exist for potassium and sodium in neurons (Eic arid Ema)? 5. What is a membrane potential ( V m ) ? What contributions do the Na / K + ATPase, K channels, and Na' channels make to neuronal membrane potential? What is the resting membrane potential in neurons? Why is it this value? What three things establish the resting (unstimulated) membrane potential in neurves? What contributions does each make to the establishment of resting membrane potential?.

How is the nervous system organized? What are the two major divisions of the nervous system?
What types of neurons is each composed of? What are the two branches of the peripheral
nervous system (PNS)? What are the two branches of the efferent PNS? What are the two major
branches of the autonomic system? 2. What are the two basic types of cells that constitute the
nervous system? What functions do they perform? Give examples of each. What glial cells did
we discuss and what functions do they perform? What are the three basic structural parts of a
neuron? What are their functions? What is a nerve? How is it different from a neuron? 3. What is
a synapse? What roles to the presynaptic and postsynaptic cells play in signal transmission?
What type of cels can be presynaptic? Postsynaptic? What roles do neurotransmitters play in this
process? What cells (pre/postsynaptic) release them? Detect them? 4. What gradients exist for
sodium and potassium in a neuron? Which direction are they? What established these chemical
gradients? What is an equilibrium potential (E Eumi? What equilibrium potentials exist for
potassium and sodium in neurons (Eic arid Ema)? 5. What is a membrane potential ( V m ) ?
What contributions do the Na / K + ATPase, K channels, and Na' channels make to neuronal
membrane potential? What is the resting membrane potential in neurons? Why is it this value?
What three things establish the resting (unstimulated) membrane potential in neurves? What
