Question
1.(8 pts) Excitable cell function. Use the terms below to fil in this chart Neurons Skeletal myocyte Cardiac myocyte Cardiac er Cells List the channel types in the plasma membrane that open in response to depolarization List the channel types that are opening and closing to promote repolarization What is a primary role for calcium in this cell type? How is Ca2 released from intracellular stores? Place the following terms in the boxes above. exocytosis of neurotransmitter, removing tropomyosin block of actin (2x), depolarization (2x), prolonged absolute refractory period, mechanical activation by membrane depolarization, activation of Ca2 release channels by Ca, Na' (3x), Ca2 (3x), K (4x), K' opening (4x), Na closing (2x), Ca closing (3x)Explanation / Answer
