What is a resting motor neuron expected to do?
exhibit a resting potential that is more negative than the "threshold" potential
What must occur for the membrane to respond to another stimulus?
For a membrane to respond to another stimulus, it must first return to its resting potential after the previous stimulus has been processed. This involves the repolarization of the membrane, where ion channels reset and the concentration gradients of ions (like sodium and potassium) are restored. Additionally, the refractory period must elapse, during which the membrane is less excitable and cannot respond to new stimuli. Once these conditions are met, the membrane can be ready to respond to subsequent stimuli.
How do you measure refractoriness?
since most of the refractories are mixtures of metal oxides they donot have sharp melting points.so the refractoriness of arefractory is generally measured as the softening temperature and is expressed in terms of pyrometric cone equivalent (PCE)
What process occurs to the cell during interphase?
During interphase, the cell undergoes growth, DNA replication, and preparation for cell division. It consists of three stages: G1 (cell growth), S (DNA synthesis), and G2 (further growth and preparation for division). Overall, interphase is a critical period for the cell to ensure it is ready for mitosis or meiosis.
Is DNA condensed in S phase?
DNA is duplicated in the S phase because in the G1 phase the cell is growing and not yet ready to divide, then DNA copies as the first step for when it is getting ready to divide. In the G2 phase the cell continues to get ready to divide once the DNA is copied.
What does the relative refractory period of a t wave represent?
The relative refractory period of the T wave in the cardiac cycle represents a phase during which the heart muscle is partially repolarized and can be stimulated to contract again, but only by a stronger-than-normal stimulus. This period follows the absolute refractory period, where the heart cannot be stimulated regardless of the strength of the stimulus. The relative refractory period is crucial for maintaining the heart's rhythm and preventing arrhythmias, as it indicates the time during which the cardiac cells are recovering but not fully ready for another action potential.
Period during which potassium ions diffuse out of the neuron due to a change in membrane permeability?
Membrane potential - a nerve cell set and ready to fire;"The wave of reverse polarity" i.e. sodium versus potassium trans-cell-membrane ion passaging - a nerve cell firing; andRecharge period - the regeneration time.
Why do you stay hungry on your period?
As women we are emotional eaters. During your period, there is a hormonal imbalance. This imbalance is because your body is getting ready to be pregnant. And you have your period to get rid of the "equiptment" your body has made to get ready for child bearing. So as your hormones are going crazy, you want to eat. Hormones cause heightened emotions and there for you are more likely to eat a lot during your period.
The US was ready to suport a revolution in this region?
During which time period? Whatever the case, Cuba is probably the answer you're looking for.
If your wife is a big woman what is the best way to get her pregnant?
The best way to get a woman pregnant is right after her period. A woman is most fertile during this period. Her eggs are ready to be fertilized.
What is the time period called in which children are developmentally ready to learn a new language?
The time period when children are developmentally ready to learn a new language easily and naturally is called the "critical period." This window typically extends from infancy to around puberty, though individual differences exist. During this period, children's brains are highly adaptable and receptive to language acquisition.
What happen while a neuron is waiting for sufficient stimulation?
While a neuron is waiting for sufficient stimulation, it maintains a resting membrane potential, typically around -70 mV, due to the distribution of ions across its membrane, primarily sodium (Na+) and potassium (K+). During this time, the neuron is polarized, with the inside being more negative compared to the outside. If the neuron receives enough excitatory signals to reach the threshold potential, it will initiate an action potential, leading to the rapid depolarization and subsequent repolarization of the membrane. Until then, the neuron remains in a ready state, capable of responding to incoming signals.
What is the time period called where children are developmentally ready to learn a new language?
The time period is called the critical period for language acquisition, which typically occurs during early childhood. This is when children are most receptive to learning and acquiring language skills. It is believed that exposure to multiple languages during this period can result in bilingualism or multilingualism.
What is a resting motor neuron expected to do?
exhibit a resting potential that is more negative than the "threshold" potential
What happens during menstruation?
the uterus lining thickens ready for the egg to be fertilised . if the egg is not fertilised then it will pass through the vagina as blood (period).
How can you rush your period?
You can't, your period only comes when it's ready.
What do you have to do to start your period?
You don't have to do anything to start your period, it will start when it is ready to start. Menstruation is controlled by hormonal changes during the menstrual cycle, it will do this on it's own without you needing to do anything to help it along.
