BONES OF THE SKULL - LEARN IN 4 MINUTES
Neural Academy・2 minutes read
The skull consists of 22 bones, including cranial bones enclosing the brain and facial skeleton bones. The temporal bones house the smallest bones in the body, crucial for hearing, while the facial bones each serve a specific function in the structure of the face and skull.
Insights
- The skull is made up of 22 bones, with 8 cranial bones protecting the brain and 14 facial bones. The cranial bones, connected by sutures, include the occipital, sphenoid, ethmoid, frontal, parietal, and temporal bones.
- The temporal bones house the smallest bones in the body, the ossicles, essential for hearing. These bones, such as the hammer, anvil, and stirrup, are located in the middle ear, connected by the external and internal acoustic meatuses, facilitating sound transmission.

Skull: 22 Bones, Crucial for Hearing
- The skull is composed of 22 bones, including 8 cranial bones enclosing the brain and 14 facial skeleton bones. The cranial bones are joined by sutures, except for the mandible, and include the occipital, sphenoid, ethmoid, frontal, parietal, and temporal bones.
- The temporal bones house the smallest bones in the body, the ossicles, which include the hammer, anvil, and stirrup. These bones are found in the middle ear and are crucial for hearing. The external acoustic meatus connects the outer and middle ears, while the internal acoustic meatus runs from the inner ear to the posterior cranial fossa.
- The facial bones consist of the mandible, vomer, maxillae, palatine bones, nasal bones, nasal concha, zygomatic bones, and lacrimal bones. The mandible is the movable jaw bone, while the maxillae form the upper jaw and the hard palate. Each facial bone serves a specific function in the structure of the face and skull.
