Define adaptation - Answer Reduction of sensory responsiveness when stimulation is unchanging. It prevents us from having to respond continuously to unimportant information Explain the adaptation process for the visual pathway - Answer Low levels of Ca++ activate recoverin which activates rhodopsin kinase, phosphorylates rhodopsin, arrestin binds and shuts off pathway Explain the adaptation process for the auditory pathway - Answer (prolonged stimulus) Stereocilia are bent, tip links...

1. Which statement regarding the sodium-potassium pump is correct? 1. The cell’s plasma membrane is more soluble to sodium ions than potassium ions. 2. The concentration of sodium ions should be higher inside the cell compartment. 3. The concentration of potassium ions should be higher outside the cell compartment. 4. The active transport involves pumping out three sodium ions and pumping in two potassium ions. 2. What is the process in which glucose is used to create energy? 1. Autol...

NSG 531 Rush Advanced Pharmacology: Exam 3 Questions With Correct Answers Latest Updated 2024/2025 / Graded A+. what is the difference between cardiac myocyte action potential and that of the CNS or ANS? - ANSWER nerve cell action potential is very short cardiac action potential is much longer they are longer to have adequate filling time in order to get a good contraction for a reasonable bolus of blood the only way this can happen is if the action potential is longer this will also mean ...

The Sliding Filament Mechanism - ️️- A sarcomere goes from z-line to z-line and has thick filaments (myosin) in the middle within the thin filaments (actin) on the sides - During contraction, the thin filaments move inwards over the thick filaments - When this happens, the z-lines move closer together - This occurs simultaneously along the entire fibre and all sarcomeres shorten to the same degree - Neither the length of the thin filaments or thick filaments themselves changes, just th...
