'ribs in' is the definition.
I don't know anything about this answer so I can't judge whether it can be defined by this definition.

'lively stew kept in cold room' is the wordplay.
'lively' indicates an anagram (letters get livened up or moved around).
'kept in' indicates putting letters inside.
'cold' becomes 'c' (eg on taps).
'room' becomes 'hall' (hall is a kind of room).
'stew' is an anagram of 'estw'.
'c'+'hall'='chall'
'estw' going inside 'chall' is 'CHEST WALL'.

'this' acts as a link.
