Action Potential diagram A) B) C) D) E) Membrane is unable to respond to further stimulation Sodium gates are open Threshold potential has been reached Repolarization occurs, Na gates close, and some K gates open Membrane is at resting potential What is the correct sequence for transmission at a chemical synapse? a) b) c) d) e) Neurotrans binds with receptors associated with postsynaptic membrane Ca2+ ions rush into neuron’s cytoplasm Action potential depolarizes the synaptic terminal membrane Ligand-gated channels open Synaptic vesicles release nerutrans into the synaptic cleft What the following “do” A. B. C. D. E. Meninges Ganglion Axon hillocks Myelin sheaths Postsynaptic membranes What is saltatory conduction? Inhibitory vs. excitatory neurotrans Areas of brain to include a) b) c) d) e) f) g) Neocortex Medulla Thalamus Pituitary Cerebellum Corpus callosum Cerebrum Blood-brain barrier Evolution of the CNS How Na-K pumps work Following hormones a) Ecdysone b) c) d) e) f) g) Glucagon Thyroxine Oxytocin GH ADH Prolactin Know difference between exo and endocrine glands Know antagonistic hormones (2 sets of them) Peptide vs. Steroid hormones 3 steps of cell signaling 2nd messengers What are prostaglandins? Paracrine vs. autocrine signaling Difference between synaptic and hormonal signaling What is a ligand? What is GTP and its significance? What are transcription and growth factors?
