The site in the neuron where EPSPs and IPSPs are integrated is the?
The Axon Hillcock is the site where EPSPs AND IPSPs are integrated in the neuron.
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.
Where in the body is lipase produced?
Lipase is produced in the Small Intestine and Pancreas.Lipase is produced in the pancreas.
Where is angiotensinogen produced?
Angiotensinogen in produced in the liver.
Is ATP produced in ribsomes?
No. ATP is produced mainly in mitochondria, or in the cytoplasm. Proteins are produced by ribosomes.
The site in the neuron where EPSPs and IPSPs are integrated is the?
The Axon Hillcock is the site where EPSPs AND IPSPs are integrated in the neuron.
EPSPs produced by many different presynaptic fibers converging on a single postsynaptic neuron causing summation on the postsynaptic dendrites and cell body best describes?
spatial summation
Will any two EPSPs override one IPSP?
false
What EPSPs will summate to a sustained value above threshold?
Generate a string of action potentials

How do different societies decide what will be produced by whom will it be produced and for whom will it be produced?
In a free market economy, you the owner gets to chose who it is produced by, how it is produced and what is prdouced. In a command economy, the government chooses how it is produced, who it is produced by and what is produced. A mixed economy is mixed with command and free market.
