An activated neuron will send an action potential from upper motor neurons to lower motor neurons to effector organs. It is able to propagate the action potential to the motor end plate by release of neurotransmitters, chiefly acetylcholine. On the terminal bouton the action potential opens voltage gated calcium channels. There is an influx of calcium in the pre-synaptic cell and it pushes the vesicles that contain acetylcholine. These vesicles will pass through the synaptic cleft and bind to cholinergic receptors on the post synaptic neuron. Each vesicle has a miniature end plate potential of 0.5mV. In a normal action potential, it will depolarize the post synaptic motor neuron from -85mV to approximately 0-15mV. So that's approximately 180 vesicles.* The influx of neurotransmitters (primarily acetylcholine) will depolarize the motor end plate and propagate the action potential.
*Threshold of an action potential is approximately -55mV so technically the minimum required to continue an action potential is around 60 vesicles.

What ray does not affect the photographic plate?
Gamma rays do not affect the photographic plate as they are highly penetrating and pass through without creating an image.
How long will 185 C of electric charge take to pass through the motor with a current of 350 mA?
To calculate the time it takes for the charge to pass through the motor, you can use the formula Time = Charge / Current. Plugging in the values, Time = 185 C / 0.35 A = 528 seconds. So, it will take 528 seconds for 185 C of electric charge to pass through the motor with a current of 350 mA.
Is a paper plate a thermal conductor?
Yes, a paper plate is a thermal conductor because it allows heat to pass through it easily due to its thin and porous nature. Heat can transfer from one side of the plate to the other, making it unsuitable for holding hot foods without insulation.
Is a plate a conductor?
No, a plate is not a conductor as it is typically made of ceramic, glass, or other insulating materials that do not allow the flow of electricity. Conductors are materials that allow electricity to pass through them easily, such as metals like copper and aluminum.
As electrons pass through a particular device magnets begin to rotate. This rotation is then used to power devices such as ceiling fans. This is a description of what happens in a(n) .?

What is the relationship between a stimulus and a reponse?
The stimulus is your bodies reaction to something, say you burnt your hand, this is the stimulus. The reaction is your bodies response to it. In this sense the stimulus will be sensed by sensory neurones which pass an electrical impulse through relay neurons until the impulse gets to the Central Nervous System. This then, gives out another impulse which travels down a Motor Neuron to the muscle telling your hand to be removed from the surface.....
How do spikes and receptors interact?
It reacts in these following steps: 1) A spike (the stimulus) is touched by receptors in the skin. 2) Receptors in the skin detect the stimulus and send electrical impulses down neurones to the sensory neurone. 3) The sensory neurone will pass these electrical signals to the CNS (Central Nervous System). 4) The CNS will pass these electrical signals to the motor neurone which once connected to the brain (through nervous cells reaching the carotid area of the body), the brain will detect and understand the feeling of the spike and will send this information the receptors.
How many functions of neurons in the nervous system?
Neurons are pathways for electrical messages to pass through. Their main function is to pass a message from one neuron to another. As a whole, they transmit these messages between a receptor (something that picks up a stimulus. A stimulus includes things such as temperature, pressure, pain etc.), the brain and an effector (something which carries out the response to the stimulus). There are three main types of neurons: Sensory neurons - receive message from receptor and transmit it to the -> Interneurons - receive message from sensory neurons and pass it on to the brain*. The brain responds and the interneurons pass the message on to the -> Motor neurons - receive message from interneurons and pass it on to an effector. *In the case of a reflex arc, where there is an unconscious response (e.g. touching a hot object) the message will bypass the brain and go straight from receptor to sensory to interneuron to motor to effector.

Are you all set with your Good To Go license plate pass for tolls?
Yes, do you have your Good To Go license plate pass for tolls?
How does the passage of a touch signal pass from skin to the cerebral cortex?
Pressure receptors in the skin pick up the stimulus. It passes along a sensory neurone to the central nervous system. Within the CNS it is transferred to the cerebral contex via an association neurone, relay neurone.
Did Gregg Sulkin play on Pass The Plate?
Yupp!
Describe the 'all or nothing' principle of muscle fiber recruitment?
HORRIBLY CONDENSED. An electrical event of sufficient strength from the end of a nerve to pass into a muscle fiber(s) (end plate) resulting fiber(s) tension. The more electrical events 'spikes" per second (rate coding) to a point the greater, to a point, the tension(s).
How is reflex handled in the nervous system?
I'm not positive, but I think that reflexes are controlled by the sympathetic nervous system (SNS). The sympathetic nervous system is part of the autonomic nervous system (ANS), which is part of the peripheral nervous system (PNS). The SNS is responsible for fight-or-flight responses. For example, if you see a shark coming directly at you, you decide to try to either get away from it (flight) or fight it off (fight). Reflexes are mediated by reflex arcs, which are neural pathways. Some sensory neurons pass directly to the synapse of the spinal cord, rather than the brain. This allows reflexes to occur relatively quickly.
Does EZ Pass use license plate information to process toll payments?
Yes, EZ Pass uses license plate information to process toll payments when a transponder is not detected.
