'gutsy' is the definition.
Although both the answer and definition are adjectives, I don't understand how one could define the other.

'woman appearing in silent broadcast' is the wordplay.
'woman' becomes 'tina' (Tina is a woman's name).
'appearing in' is an insertion indicator.
'broadcast' is an anagram indicator (letters scattered or cast around).
'silent' with letters rearranged gives 'intesl'.
'tina' inserted inside 'intesl' is 'INTESTINAL'.
