Select HTML elements inside another with jQuery

Let's say that I have a function defined in JQuery, I write it in a simplified way:

miFunc = function(elem) {
    ...
}

elem is an HTML element. It could be a past element when making the call for some mouse event. For example, a div element with the onmouseover attribute, as in the following code.

<div class"unaClase" onmouseover="miFunc(this);">
    <span class="otraClase"> ... </span>
</div>

Having elem , how could I access the elements that have the class otraClase and are within elem ? For example, for the code shown, select the element span to modify its content.

Obviously I am looking for something dynamic and these examples are concrete cases. The elements might not be span and there could be several (or even none).

If you know that elem is an HTML element, decorate it with $() and filter from it:

miFunc = function(elem) {
    var otraClaseElems = $(elem).find(".otraClase");
}
