Heading for doctor? Final resting-place apparent! (4)
I believe the answer is:
tomb
'resting-place apparent' is the definition.
I can't tell whether this defines the answer.
'heading for doctor? final' is the wordplay.
'heading for' becomes 'to' (to head for a place is to go to it).
'doctor?' becomes 'mb' (Bachelor of Medicine, Medicinae Baccalaureus).
'final' is a charade indicator (letters next to each other).
'to'+'mb'='TOMB'
Can you help me to learn more?
(Other definitions for tomb that I've seen before include "Building for a body" , "Crypt or grave" , "Resting place" , "Last resting-place" , "Large vault" .)
