match from #51 to 60 and mark true or false from #61 to 75 please :)
Matchthe following. Each choice is used only once. 51) Intracellular Ca2+ a)0.0001mM 52) Intracellular K+b)150 mvl 53) Extracellular K+C)1.0 mM 54) Extracellular Nat d)5 mM 55) Extracellular Ca2+ e)135-145 mlu 56) Alphareceptors 57) B1 receptors 58) B2 receptors 59) Nicotinicreceptors 60) Muscarinic receptors a) Norepinephrine only b) Both Epinephrine and norepinephrine. c) Epinephrine only d) secreted by preganglionicfibers. e) secreted by post ganglionicfibers For the following true/false items mark "A" for trueand "B" for false. 61) Sympathetic pathways havevery long post-ganglionicfibers. 62) Parasympathetic pathways haveaganglionvery close to the target organ. 63) A touch receptor will generate an action potential 64)A motor neuron will carry a graded potential down its axon. 65) Charged particles like ions can cross cell membranes more easily thannonpolar molecules like oils 66) Proprioception isthe awareness of lateral acceleration. 67) Nociceptors are small but elaborate multicellular structures. 68) Equilibrium isconsideredto be a special sense. 69) Lateral inhibition can enhance visual acuity 70) Lateral inhibition occurs where aneuron sensitizes adjacent neurons to stimuli 71)A Neuron has enough potassium ions to generate about ten action potentials if the Na/K pumps wereto stop working 72) Cerebrospinal fluid completely recirculatesthreetimes a day 73) Viscerosensory input is sent directly to the thalamus 74) Autonomic pathways only irvolve one neurorn. 75) The axons and dendritesthat run between ganglia are typically heavily myelinated.Explanation / Answer
