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
What else can I help you with?
What are permanent genetic changes that occur in a body cell called?
rna A mutation.
In neurons where does protein synthesis occur?
Protein synthesis in neurons occurs in the cell body, also known as the soma. Messenger RNA (mRNA) produced in the nucleus is then transported to the cell body where ribosomes translate the mRNA into proteins that are necessary for the neuron's function and structure.
What is the accumulation of multiple EPSPs on a postsynaptic cell is called?
The accumulation of multiple excitatory postsynaptic potentials (EPSPs) on a postsynaptic cell is called temporal or spatial summation. Temporal summation occurs when multiple EPSPs are generated in rapid succession at the same synapse, while spatial summation involves simultaneous EPSPs from multiple synapses. Together, these processes can lead to the depolarization of the postsynaptic membrane and potentially trigger an action potential if the threshold is reached.
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.
When impulses from various sources have an additive effect on a neuron the process is called?
When impulses from various sources have an additive effect on a neuron, the process is called summation. This can occur through temporal summation, where multiple impulses from the same source rapidly fire in succession, or spatial summation, where impulses from different sources converge at the same time to reach the neuron's threshold for firing.
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 does two cell division occur?
anywhere in the body but it sometimes does depend on the cell type
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.
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.
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.
Lymphocytes that are responsible for monitoring the events that occur inside the body's cells are which type of cell?
T cells
What is the jelly like body of the plant cell where the chemical reactions of life occur?
cytoplasm
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.
