Pages 20

INTRODUCTION Shaped like an inverted cone, the 12-14 cm long musculofascial tube that is the pharynx hangs down from  the pharyngeal tubercle at the skull base and fuses with the oesophagus below at the level of the lower border of the cricoid cartilage. It is the continuation of the common pathway for respiration and digestion that begins with the oral cavity.
