The cell will become _____. depolarized What three things create myelin? Glial cells Schwann cells Oligodendrocytes A G Protein does not interact with the _____. ligand A G Protein interacts with at least _____ other proteins. two A G Protein cannot be an _____ ______. ion channel Otago, the food loving dog, was with two of her doggie family members last weekend. Whenever someone came to the door, the three all ran from different parts of the house to bark at the person. If the dogs were neurons, they would be providing an example of _________. convergence Typical neurons send messages via neurotransmitters by way of the neuron's ______. axon ______ is to ______ as epithelial cells are to ependymal cells. outside environment outside the CNS What type of receptors can function as an ion channel and enzyme but not at the same time? membrane bound What type of receptors can interact with JAK kinase to get more receptors or ion channels made? membrane bound Carmen found Brutus after a scrap with Bucky Badger, Brutus had several abrasions on his limbs that Carmen wrapped with gauze while they heal. If Brutus was a neuron in your arm, then we could correctly characterize his limbs as _____ and his bandages as _______. processes Schwann cells Graded potentials are the result of _____ _____ in the flow of ions. local change Graded potentials occur due to an _______ permeability of the plasma membrane. increased ________ may not formulate a response to afferent information received. interneurons Membrane-bound receptors only enter the cell if they are _______. endocytosed Electrical synapse messages move ________. bidirectionally There would be more pathogens present around the neurons if lost what type of glial cells? astrocytes ______ are extensions out of the plasma membrane? processes Which type of neurons do not have dendrites? afferent What structures gather information about neurotransmitters and are environmental stimuli? dendrites What exposes the axon to interstitial fluid? nodes of ranvier What are glial cells that are associated with the immune system? microglial Glial cells are only found in the ______. CNS An ____ could lead to the G proteins involment
