1. An action performed by a device, department, or person that produces a result. Function remains more or less fixed whereas the purpose (which indicates intention or objecti…ve) generally changes. For example, the function of a hammer is to strike something nearby whereas its purpose (what to strike and why) could be anything the hammer-wielder has in mind. 2. Mathematics: A mathematical relationship in which a quantity (dependent variable) depends on or is determined by another quantity (independent variable) or quantities. The dependent variable is said to be a function of the independent variable(s). If something is done, or something happens, to the independent variable(s), it is reflected in the dependent variable. See link below
A function is a rule which relates the values of one variable quantity to the values of another variable quantity, and does so in such a way that the value of the second varia…ble quantity is uniquely determined by (i.e. is a function of) the value of the first variable quantity. A simpler answer A function is the same as the word "use". The function of a car is to transport people. The use of a car is to transport people. The function of a knife is to cut things. You use a knife to cut things. Answer definite purpose What is the structure supposed to do? What was it designed for? 1. ) z^8 + i*z^4 -1 =0 2. ) z* (zconjugated) - 3* (z- zconjugated) = 2+ 3*i
Functionality is defined as being the state or quality of functioning. When talking about computers or video games functionality is used to describe the capabilities that …are associated with the software or hardware for the computer.
Functions refer to duties, responsibilities or obligations of a particular person or thing. The functions of the president and other public officers are defined by the con…stitution.
A function f(x)=y can have only one y-value for any given x-value. Many x-values can have the same associated y-value, however. What makes a function more "special" than o…ther relations is that there is one unique out-put value for each input value. Imagine a "machine" that you put a number into. The machine takes your number, and changes it into a new number. Let's say you put the number 5 into the machine, and the number 10 comes out. Then I put the number 5 into the machine, and the number 10 comes out. We put in the number 5, and again, a 10 comes out. Then we have a function. If I put in a 5 and a 10 comes out, but you put in a 5 and a 7 comes out, we do NOT have a function. We used the same input, but got different out-put. That is what is NOT a function. When relations are NOT functions, there is no predictable answer to a given questions. We do not spend a lot of time in many math classes looking at things that are NOT functions, because they can be too "random" to make good problem-solving tools. Some types of things we might look at which are NOT functions are circles, hyperbolas, ellipses, equations where the dependent variable is squared and other types of things where graphs "double-over" on themselves. A function is an expression or relationship that involves one or more variables; without variables, the relationship is not a function.
Surrounding the myelin sheath, there is a thin membrane called neurilemmal sheath. This is also called neurilemma or sheath of Schwann. This contains Schwann cells, whic…h have flattened and elongated nuclei. The cytoplasm is thin and modified to form the thin sheath of neurilemma enclosing the myelin sheath. One nucleus is present in each internode of the axon. The nucleus is situated between myelin sheath adn neurilemma. At the node of Ranvier (where myelin sheath is absent), the neurilemma invaginates and runs up to axolemma in the form of a finger like process. In nonmyelinated nerve fiber, the neurilemma continuously surrounds axolemma. Neurilemma is absent in central nervous system. Neurilemma is necessary for the formation of myelin sheath (myelinogeneis).
Schwann's cells become apposed to an axon and envelops it in a trough. It then begins to rotate around the axon, wrapping it loosely in successive layers of its plasma membran…e. Eventually the Schwann's cell cytoplasm is forced from between the membranes and comes to lie peripherally just beneath the exposed portion of the Schwann's cell membrane.
The neurilemma is the Schwann cell. This helps with regeneration of cells. The nerve cells in the brain do not have neurilemma and therefore, cannot regenerate.
Neurolemma is just an outer shell of the myelin sheath, it's function is to protect a myelinated cell from injury and aid in its healing from injury by allowing information to… travel faster to the brain that an unmyelinated cell.
We need more information to answer this question, but since you placed it in "conditions and diseases," perhaps you are asking about a person who is basically getting by and m…anaging to function (to eat, to sleep, to speak, to understand questions that are asked) but not necessarily feeling very well. Sometimes, the organs of the body are said to be functioning if they are working properly, as they are supposed to. Or you may hear that someone is a "functioning alcoholic"-- this means the person does in fact have a major drinking problem but during work hours, he or she is able to go to work and get their job done on a basic level; or they can put aside certain periods of time for doing things that seem normal, even if the majority of their free time is spent drinking.
Yes, the mylean sheath is the same as the neurilemma.
Yes, the mylean sheath is the same as neurilemma.
A function is not a function if it passes through the vertical line test more than once, and it is not linear or a quadratic.
