👉 Saccobranchia, or Brachycephalic Saccobranchia, are a group of cranial bones that form the skull. These bones include the saccus (the bridge between the two ears), the maxilla, the mandible, and the temporal bone. The saccus is crucial for speech production in humans because it allows the tongue to move back and forth when speaking, which helps to produce the correct vowels and consonants.
