Nervous System	Nervous Tissue	Action Potentials	The embryologic perspective	The Somatic Nervous System
100 What are the two main divisions of the nervous system? Central Nervous System(CNS) and Peripheral Nervous System (PNS)	100 What are the parts of a neuron? dendrites, soma, axon, myelin, node of ranvier	100 What is depolarization? reversal of charges -70mv to +35mv	100 True or False. 16 days after fertilization the nervous system develops from ectoderm True	100 What is sensation? A stimulus that has been recieved by the brain bringing awareness to the organism.
200 What are the general functions of the nervous system? Stimulate all movement, recieve sensory input, store and intergrate information, maintain homeostasis	200 What is the name of a neuron that is rare, found in retina of the eye? Bipolar	200 What is hyperpolarization potential briefly lower than -70mv	200 Fill in blank. Cells differentiate into___ that develops into a a neural tube (develops into parts of CNS) Neural folds	200 What is perception? How the brain interpets the sensation.
300 Diference between nucleus and ganglion Nucleus is locaed in the CNS and ganglion is located in the PNS.	300 Are microglial cells found in the CNS or PNS? CNS	300 What is the resting potential? -70mv	300 Fill in blank. Filure to close off tube during development may lead to defect called___ Spinal Bifida	300 What are the funtions in receptors? sense stimuli and send signal to CNS.
400 Difference between a tract and nerve A tract is a bundle of axon fibers in CNS and a nerve is bundle of axon fibers in PNS.	400 What are astrocytes? They provide support and connection between neurons and blood supply	400 True or False. The refractory period is during AP where another AP cannot be initiated; has 2 phases. true	400 Neural crest develops where ? Several parts of the PNS	400 What are the two categpries in receptors? general and special
500 What is a dendrite? process that branches off soma; recieves input from other neurons; may be many per neuron.	500 True or false. Multipolar neurons are majority of all neurons; most in brain are multipolar true	500 What are the 2 phases in the refractory period? Absolute refractory period and relative refractory period	500 The primary vesticle stage has has how many regions? three	500 What are general senses? widely distributed receptors
