How are women presented in Macbeth?

Women don't have such a large role in this play as men, as in most of Shakespeare's plays. Lady Macbeth being the main female part would be the main focus, the fact that she goes mad and dies shows that she is presented as having feminine sensibilities and in her mad muttering she is affected by the death of her child and blood. However she does spur Macbeth on and is a force towards his downfall in the play.
