What are the main bones used to surf?
Leg bones including Femurs
What are the various potentials used in antenna theory?
scaler electric potential vector magnetic potentials retarded potentials
Why is the term action potential used to describe a nerve impulse?
It is a difference in charge supplied by ion position. In resting potential the tendency is for the inside of the cell membrane to have a negative ionic charge, while the outside of the membrane has a positive charge. The change, back and forth in these two charge potentials is the conduction of charge down the neuron and is called the action potential.
What is the skull used for?
An animal's skull is the main bones of the head.
What is the volley principle?
The Volley Principle is an information encoding scheme used in human hearing. Nerve cells transmit information by generating brief electrical pulses called action potentials. Sound is encoded by producing an action potential for each cycle of the vibration, eg. 200Hz results in a neuron producing 200 action potentials per second. BUT, neurons can only produce action potentials around 300 to 500 Hz. The human ear overcomes this problem by allowing several nerve cells to take turns performing this single task. The volley principle was proposed to deal with this apparent anomaly between the behaviour of single neurons and groups of neurons.
What are the main bones used in ballet?
Ballet uses SO MANY bones in your body. Probably the bones in the legs, feet, arms, back, neck, and hips. Your pelvis and spine need to be in line constantly, so that might be your answer.
What is used to measure potential difference inparallel circuits?
A voltage test meter is used to measure voltage potentials in a circuit.
What ions are important in the formation of membrane potentials?
Potassium and sodium are involved in the action potential present in the neurone. When a stimuli is detected Sodium is pumped into the neurone causing depolarisation this flow of charges causing a voltage known as the action potential. When the stimuli is no longer detected sodium and potassium flow out to cause repolarisation.
When is flame emission spectroscopy used?
It can be used for element identification and can used in Atomic spectroscopy and can be used to help "atoms with low ionization potentials become ionized."
What does a conduction velocity of an action potential depend on?
An action potential does not have a conduction velocity. Rather, it makes sense to measure the conduction velocity of nerves or nerve cells and this is usually done in metres per second (m/s.). An action potential is characterised as "an all or none response". This means you cannot alter the characteristics of an action potential in a given nerve cell. If you get a nerve cell and manage to get it to threshold, produce and measure an action potential 1000 times or more at the exact same point on the cell, the action potential you measure will not change in timing or amplitude. Information travels down a nerve cell through action potentials. But it is not one action potential that travels the whole length of the axon. Instead what happens is that one action potential causes the next bit of the nerve cell to reach threshold and therefore creates an entirely new action potential. So you actually need multiple action potentials to happen along a nerve cell to send information down it. We call this "propagation of action potentials" since each action potential produces a new one. More properly, it is referred to as "saltatory action potential conduction". Conduction velocity is basically a measure of how quickly we can produce a series of action potentials to travel the distance of the nerve cell axon. Since action potentials only happen at each "Node of Ranvier", then the longer the distance between each node (internodal distance), the faster the conduction velocity of a nerve cell. Since the internodal distance is positively correlated with myelin thickness, more thickly myelinated nerve cells have faster conduction velocities. The thickest and fastest nerve cells are motor neurones and Ia fibres from muscle spindles with a diameter of 12-20 micrometres and a conduction velocity of 70-120 m/s. The thinnest/slowest are fibres used to convey slow pain (<1.5 micrometres and 0.5-2 m/s).
How are action verb andhelping verbs alike?
Action verbs and helping verbs work together to describe the state of or action of the subject. Some words that are helping verbs can be used as a main verb. Examples: Jack is a student. ('is' is the main verb in the sentence) Jack is walking to class. ('is' is the helping verb and 'walking' is the main verb in the sentence)
Are bones used in manufacturing of tooth paste?
My uncle, Paul raysinberry, worked in a toothpaste manufacturer (colgate) And yes, bones are used in toothpaste. Not human bones but bones. Bones as in bones. HOPE THIS HELPED.
