How can I show title of attachments in posts?

Hey everyone, I was wondering if i can get some help with this issue im having. I am currently using the code provided by the author(Patrik) to show attachments in posts which is

<?php
$args = array(
    'post_type' => 'attachment',
    'numberposts' => null,
    'post_status' => null,
    'post_parent' => $post->ID
);
$attachments = get_posts($args);
if ($attachments) {
    foreach ($attachments as $attachment) {
        echo wp_get_attachment_image($attachment->ID, 'medium');
    }
}
?>

How can I show the title of the attachment? Can I show it under the attachment?

Thanks for the help. Would appreciate any advice
