Explore the intricate anatomy of the skull in this comprehensive lecture. This video provides a detailed overview of all the bones of the skull, followed by an in-depth discussion of the cranial bones. Learn about the structure, location, and significance of these vital bones, including their role in protecting the brain and supporting facial structures. Whether you're a medical student, professional, or anatomy enthusiast, this lecture simplifies complex concepts with clear explanations and visuals.

What You’ll Learn:

Classification of skull bones: cranial and facial.
Detailed breakdown of cranial bones: frontal, parietal, temporal, occipital, sphenoid, and ethmoid.
Clinical significance of skull anatomy.

The skull is made up of 22 different bones – 8 cranial bones that enclose your brain within the neurocranium, and 14 facial skeleton bones. There are also 6 ear bones. With the exception of the mandible, the bones of the skull are joined by sutures, which are a kind of joint that is synarthrodial – in other words, it can’t move.
The 8 cranial bones include one occipital bone, one sphenoid bone, one ethmoid bone, one frontal bone, a pair of parietal bones, and a pair of temporal bones. The occipital bone is found at the back of the skull. The sphenoid bone can be found in the middle inferior portion of the neurocranium and kind of looks like a butterfly. It is in front of the temporal bone and is one of 7 bones that articulate to form the orbit. The other six are the frontal bone, the lacrimal bone, the ethmoid bone, the zygomatic bone, the maxillary bone, and the palatine bone.
The ethmoid bone is found between your eyes, located at the roof of the nose, and separates the nasal cavity from the brain. The frontal bone is the bone of your forehead. It has two portions – one vertical, and also the horizontally-oriented orbital portion.
The remaining 4 bones are a pair of parietal bones and a pair of temporal bones. The parietal bones are joined together at the top of the skull. Together, they form the top and sides of the neurocranium. Each bone is roughly quadrilateral in shape. The temporal bones can be found at the sides and base of the skull. They are overlaid by what we call the temples. It is inside the petrous part of the temporal bone that we find the ossicles – the bones of the middle ear and the smallest bones in your body. A set of three ossicles is found on each side of your head, so there are 6 ossicles in total. These bones include the hammer, anvil, and stirrup, also called the malleus, incus, and stapes. The ear canal, which joins the outer and middle ears, is known as the external acoustic meatus. There is also the internal acoustic meatus, which is a tube running from the inner ear to the back of the skull – to what’s called the posterior cranial fossa. We will discuss the three fossa of the skull will be discussed in a later video.
Overview of the anatomy and functions of the bones of the skull;
Brain case and face: introduction to the neurocranium and viscerocranium;
Features of the neurocranium: skull cap (parietal bones, frontal bone, occipital bone);
Features of the neurocranium: base of the skull (sphenoid bone, occipital bone, temporal bone, maxilla, and zygomatic bone);
Bones of the face: maxilla, mandible, zygomatic bone, nasal bone, palatine bone, lacrimal bones, vomer and inferior nasal concha;

Here are the eight cranial bones, with a mnemonic (memory trick) to help you remember them:

-Ethmoid bone (1)
-Frontal bone (1)
-Sphenoid bone (1)
-Parietal bones (2)
-Temporal bones (2)
Occipital bone (1)

To remember them, remember this phrase (make it into a cranial bones song if you want): Ethan's Fried Spanish Pasta Tempted Octavia.

The fourteen facial bones may seem even more daunting, but these mostly come in pairs, so there aren't as many as it seems.

-Mandible (1)
-Vomer (1)
-Maxilla (2)
-Lacrimal bones (2)
-Nasal bones (2)
-Inferior Nasal Concha (2)
-Palatine bones (2)
-Zygomatic bones (2)
