If the Health Savings Account (HSA) owner dies, the HSA becomes the property of the named beneficiary. If the spouse is the beneficiary, the HSA can continue and the surviving spouse is subject to income tax only on HSA distributions not used for qualified medical expenses.
Carotid sinus hypersensitivity (CSH) is an exaggerated response to carotid sinus baroreceptor stimulation. It results in dizziness or syncope from transient diminished cerebral perfusion. Although baroreceptor function usually diminishes with age, some people experience hypersensitive carotid baroreflexes.
(B) Ca2+ channels open in response, and Ca2+ ions diffuse into the end bulb. The influx of Ca2+ causes many of the synaptic vesicles to fuse with the neuron membrane. Thousands of acetylcholine (ACh) molecules are released into the synaptic cleft. A few diffuse across the synaptic cleft and bind to the acetylcholine receptors that are embedded in the membrane of the postsynaptic neuron. (C) When both ACh binding sites are occupied, the acetylcholine receptors open.
