10 14 SI A ECL 365 1 is the basic cellular unit in the nervous system 2 and are the two different kinds of processes Describe each 3 Name the 3 classes of neurons and describe them 4 Which neuron class corresponds to each of the following Motor Sensory 5 True False All classes of neurons are within the central nervous system 6 What cells covers the axon 7 What structure along the axon allow a signal to be passed along the axon so quickly 8 What does Binary mean and to what does it refer 9 Describe the resting state of a nerve cell 10 Describe the conduction of an Action potential which is also called a 11 During the depolarization stage the inside of the cell becomes and during the repolarization stage 12 Small axons conduct because resistance to current flow is high and axons with quick responses are 13 In what other way do vertebrates increase conduction speed in an axon This increases conduction 14 Name and describe the two types of nerve synapses 15 Describe synaptic transmission in a chemical synapse 16 In vertebrates and invertebrates the nervous system displays a in complexity from nerve net to linear to which includes a brain and spinal column 17 Vertebrates display of axons which connect the spinal cord and brain Unlike most invertebrates vertebrates have a nervous system The changed little over vertebrate evolution 18 There is an increase in and of brains when comparing birds and mammals to earlier lineages 19 Larger animals tend to have brains 20 Birds have enlarged lobes but reduced portions of the brain 21 True False There is no chance or potential for brain repair 22 True False Efferent and afferent neurons are sometimes bundled in the same nerve 23 Describe the peripheral nervous system 24 The nervous system includes skeletal muscle while the nervous system includes muscles and glands 25 The parasympathetic system increases decreases heart rate while the sympathetic system increases decreases heart rate
