What happens with the many synaptic inputs on a cell body?
Ca ions bind to their binding sites that in turn allows Na ions to flood into the cell body and cause depolarization. this will continue down the cells axon until it bombardes the next cell with synaptic input
What 2 things go into photosynthesis?
The two main inputs for photosynthesis are sunlight and carbon dioxide. Plants use these inputs to produce glucose (energy) and oxygen as byproduct.
What is reaction inputs of photosynthesis?
6 carbon dioxide molecules and 6 water molecules.
What is the input in for aerobic respiration?
The inputs for aerobic respiration are glucose and oxygen. Glucose is broken down in a series of chemical reactions to produce ATP (energy), while oxygen is the final electron acceptor in the electron transport chain.
How does the brain create connections between the microscopic cells?
Axons and dendrites make neuronal signal connections via synapses, which are small spaces between the output (axon) and inputs (dendrites) of neurons, through which chemicals released by axons, called neurotransmitters, diffuse to and stimulate new neural impulses in dendrites, thus functionallyconnecting the brains neurons.There are also small molecules called synaptic adhesion molecules which protrude from both the end of an axon and the beginning of a dendrite, into the synapse, which then stick to each another, thus holding the axon and dendrite in position together, although the cell membranes of the two neurons do NOT touch nor merge, and there is no exchange of cytosol between them.

What is there term temporal summation refers to?
Temporal summation refers to the process by which a neuron combines multiple excitatory signals that occur in quick succession over a short period of time. When these signals arrive closely together, their effects can accumulate, increasing the likelihood of generating an action potential. This phenomenon is essential for the processing of information in the nervous system, allowing for more nuanced responses to stimuli. It highlights how the timing of synaptic inputs can influence neuronal activity.
Factors that influence the elasticity of supply?
1. Flexibility of inputs 2. Mobility of inputs 3. Availability to produce substitutes 4. Time
What is the firing rate of a neuron?
The firing rate of a neuron refers to the frequency at which it generates action potentials, typically measured in spikes per second (Hz). This rate can vary significantly depending on the type of neuron and its physiological state, ranging from a few spikes per second to hundreds. Factors such as synaptic inputs, membrane potential, and the overall activity of the neuronal network can influence a neuron's firing rate. It plays a crucial role in encoding information and communicating within the nervous system.
What are inputs and outputs with an example?
Activity/Function : Ceiling Fan. Input : Electric current. Output : Moving air.
What is an example of an input in activity-based costing?
Resources are inputs, such as materials, labor, equipment, and other economic elements consumed by an activity in the production of an output. Outputs are products, services, and accompanying information flowing from an activity.
What is the difference between a diverging circuit and a converging circuit?
A diverging circuit is one neuron sending impulses to multiple post-synaptic neurons. A converging circuit is many neurons converging on one post-synaptic membrane.
How global macro economic factor influence demand and supply of agricultural inputs?
There are many economic factors that influence the demand and supply of agricultural inputs, although the main ones are, when price goes up demand goes down, when the price of one product rises this in turn increases demand for other products. The weather also plays a major part in this.
What are the inputs of TQM?
inputs of TQM
What is Composition of inputs at Starbucks?
what the composition of inputs for Starbucks
How does money greases the wheels of the economic activity?
source of inputs; used to purchase capital goods. payment of labour. medium of exchange in economies. it is central in all economic activities.
Numerous nerve impulses arriving at a synapse at the same time exert a cumulative effect?
Kind of. Each neurone can have thousands of inputs from other neurones arriving at the same time. It all depends on the types of signal arriving from the other neurones. There are 2 types of incoming signal; 1. Excitatory Post-synaptic potentials (EPSPs) - These inputs depolarise the neurone (bring the negative voltage of the neurone closer to 0mV). 2.Inhibitory Post-synaptic potentials (IPSPs) - These inputs hyperpolarise the cell (make the neurone voltage more negative). Some of the inputs coming to the neurone will be EPSPs, some IPSPs. If all the inputs come in and there are more EPSPs then the neurone will depolarise. If the neurone depolarises to the firing threshold (around -40mV) then an action potential will be propagated and the neurone will transmit the message to the next neurone in the chain. If the majority of the inputs are IPSPs then the neurone will hyperpolarise and will not fire. If there are more EPSPs than IPSPs but the neurone still doesn't depolarise enough to reach the firing threshold then the neurone will not fire.
