1, how does the body encode intensity changes in sensory stimuli? Primarily with frequency coding; greater intensity leads to a higher frequency. Also with population coding; a greater number of receptors will be triggered by a stimulus of increasing intensity. What is sensory adaptation? The dynamic change in the frequency of triggered AP’s with a static stimuli; this occurs at the level of the receptor What types of adaptation do sensory receptors exhibit? Tonic (slowly adapting) and phasic (rapidly adapting) Which type of sensory adaptation detects the beginning of (onset) and the end of (offset) of a stimulus?
1. Depolarization of the cell membrane opens voltage-gated Ca2+ channels 2. SR may release additional Ca2+ with depolarization 3. SR can be stimulated by hormones and neurotransmitters to release Ca2+ via IP3gated Ca2+ channels Describe excitation-contraction coupling in smooth muscle: Intracellular [Ca2+ ] increases ↓ 2+ Ca binds to calmodulin activating myosin light-chain kinase ↓ Myosin is phosphorylated and binds to actin ↓ Shortening occurs What causes relaxation in smooth muscle? Dephosphorylation of myosin CLINICAL VIGNETTES A researcher has found a new drug, but to be most effective, it has to get across the lipid bilayer.
Either increasing the oil/water partition coefficient or decreasing the overall size of the molecule. A young man is inadvertently given a dose of tetrodotoxin and his excitable cells are no longer able to generate action potentials, how did this occur? Voltage-sensitive Na+ channels are blocked and action potentials cannot be produced Some of a patient’s blood is collected and an unknown solution is added to the sample. When the technician views the slide, all of the red blood cells (RBCs) have lysed.
