incoming signals to cell body are summated
some signals are positive and some are negative
ESPS cause voltage to become more positive making ti easier for the cell to fire
ISPS cause voltage to become more negative so more difficult for cell to fire
At any moment , cell body is bombarded with many thousands of positive and negative influences
summation of inputs determines whether cell will fire an action potential :needs to exceed threshold

rna A mutation.
What is the egg cell in a female's body?
The egg cell, also called the haploid cell, is the female gamete. A pair of gametes, egg and sperm, are what are needed in order for reproduction to occur.
Where do the different stages of photosynthesis occur in the cell?
in the chloroplast cell
Where does reactions occur in a electrolytic cell?
In an electrolytic cell
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
Where did osmosis occur in your body?
Cell
Where do most biochemical reactions occur in the body?
In the cell.
Does mitosis or meiosis occur in all body tissue's?
Mitosis does not in fact occur in all of the tissues of the body. Mitosis occurs in all tissues of the body that are not sex tissues.
Where does two cell division occur?
anywhere in the body but it sometimes does depend on the cell type
Why is it important that summation not occur in heart muscle?
Basic muscle summation -an increase in the frequency with which a muscle is stimulated increases the strength of contraction. With increased stimuli to the heart if summation occurred the contractions would keep increasing.
In neurons where does protein synthesis occur?
in the neuron cell body
Is the summation of a drug present in the body after repeated medication?
Accummulation
Does cellular respiration occur in all cells?
Yes! It is in every body cell.
Where does synapses occur in the spinal cord?
Cell body of sensory neuron - in dorsal root ganglion. Cell body of motor neuron - in anterior gray horn.
What are permanent genetic changes that occur in a body cell called?
rna A mutation.
Why is a summation greater than an integral?
It's not. It depends on the method you use for summation whether summation > integral or integral > summation.
