Which type of stimulus is detected by photoreceptors?
light
What determines the modality of the stimulus?
The scientist, or "operator" of the experiment, gets to determine the type of stimulus used (as long as it is within ethical bounds).
Will you get a stimulus check in 20010?
who will get a stimulus check in 2011
What are the pros and cons of the stimulus plan?
for a stimulus plan to me it means a financial bailout or a type of insurance to keep your economy afloat. It depends on what the stimulus plan is used for to determine the pros and conns like for instance. If the government plans a stimulus plan for wall street will it be for the right reasons and how will you benifit form it if you are under a ressecion..
What type of diffusion is Economic development through international trade is an example of?
stimulus diffusion
Which type of membrane channels are found at the axon?
Voltage-gated Na+ and voltage-gated K+ channels
Type of membrane channel that opens when distorted?
Mechanically-gated
Which membrane potential occurs because of the influx of Na plus through chemically gated channels in the receptive region of a neuron?
An excitatory postsynaptic potential, a type of graded potential, occurs because of the influx of Na+ through chemically gated channels in the receptive region, or postsynaptic membrane, of a neuron. Graded potentials are generated by chemically gated channels, whereas action potentials are produced by voltage-gated channels.
What type of channels that are present within the varicosities of autonomic neurons are absent from the axon terminal of other neurons?
Voltage-gated Sodium ions and Potassium ions channels
What type of ion channels does an actions potential in the axon terminal of a motor neuron open?
voltage-gated calcium ion channel
An action potential in the axon terminal of a motor neuron opens what type of ion channels?
Exocytosis
Which type of stimulus is an allergen such as pollen?
External Stimulus
What is the channel responsible for absolute refractory period?
Na+ channels influx (phase 0) then L-type Ca 2+ (slow calcium channels) to maintain the plateau (phase 2) then the first half of phase 3 - where voltage-gated and the delayed (iK1) k+ channels are starting to open and the Ca++ are starting to close. Phases 0-3.5 this is the absolute refractory period - PERIOD
What type of stimulus do thermoreceptors react?
Thermoreceptors react to variation in temperature.
What type of channel on the postsynaptic membrane binds neurotransmitter?
a chemically gated channel
Which type of stimulus do mechanoreceptors detect?
Sound
What type of stimulus is detected by photoreceptors?
Light
