The internal cranial base contains the brain, the intracranial parts of cranial and spinal nerves, meninges, blood vessels, and cerebrospinal fluid. Located on the medial wall of the petrous ridge in the posterior cranial fossa is the internal acoustic meatus (see Figure 9). This opening provides for passage of the nerve from the hearing and equilibrium organs of the inner ear, and the nerve that supplies the muscles of the face.

The palatine bone is one of a pair of irregularly shaped bones that contribute small areas to the lateral walls of the nasal cavity and the medial wall of each orbit. The largest region of each of the palatine bone is the horizontal plate. The plates from the right and left palatine bones join together at the midline to form the posterior quarter of the hard palate (see Figure 7.3.7a). The facial bones of the skull form the upper and lower jaws, the nose, nasal cavity and nasal septum, and the orbit.

The skull is the skeletal structure of the head that supports the face and protects the brain. It is subdivided into the facial bones and the cranium, or cranial vault (Figure 7.3.1). The rounded cranium surrounds and protects the brain and houses the middle and inner ear structures. Finally, the posterior wall of the nasal cavity is formed by the anterior surface of the body of the sphenoid, and it presents a pair of openings called the choanae. The external cranial base is the outer aspect of the skull base.

But when it comes to design, you can’t expect everyone to understand. And for a lot of designers, this means incorporating different symbols like skulls into their design. Don't worry everything just start from a scratch process.

If an error occurs in these developmental processes, a birth defect of cleft lip or cleft palate may result. The infratemporal fossa is an irregular-shaped space situated on each side of the skull below the temporal fossa and deep to the ramus of the mandible. It is located between the base of the skull, lateral pharyngeal wall, and ramus of the mandible. The infratemporal fossa communicates with the temporal fossa via space to the zygomatic arch. It also communicates with the pterygopalatine fossa via the pterygomaxillary fissure. The temporal fossa is a depressed area on each side of the skull bounded by the temporal lines and the zygomatic arch.
Your artwork when drawing human faces will no longer look like a depiction of an alien. Below, we will provide a list of recommended materials as a well as step-by-step instructions on how to draw a skull realistically. A lateral view of the isolated temporal bone shows the squamous, mastoid, and zygomatic portions of the temporal bone. This is already going from a simple skull drawing to something more detailed!

All of those shapes are not a waste of time if you are wanting a life-like skull by the end of your sketch. Some artists have mastered the skill of dimension and the detail of shading. So much so that it looks like a 3D image has been printed onto paper or canvas. This next step is vital for bringing life into your drawing – ironic is it not?
Unique Skull Designs and Illustrations
I hope this tutorial gives you all the tools you need to create successful drawings of your own. Skull drawing is easy once you mark the placement of the different features. The outer layer of the periosteum is a tough fibrous layer formed by collagen fibers that can be subdivided into a superficial and deep portion.
Depending on the size and placement of the tattoo, it can be covered up with additional tattoos or removed surgically. Check out the infographic below to learn about the symbolism of animal skulls that make popular tattoo choices. People have used them to show that they are cool, daring, fearless, and much more.
Skulls were considered a symbol of life and rebirth in these ancient cultures, rather than something morbid or macabre. They believed that death was just a part of the natural cycle and celebrated it as a continuation of life. The skulls were often used in rituals, such as the famous Aztec festival of the dead, known as Dia de los Muertos (Day of the Dead). The skulls are decorated as a way to pay tribute to and celebrate the lives of the deceased. They are often placed on altars alongside offerings of food, drinks, and personal belongings of the departed. The colorful and ornate designs are believed to attract the spirits of the loved ones back to the living world during this special occasion.
Using white will also help to add dimension, as it mimics the look of light and shadows. If you like the idea of a “death moth”—aka a moth with a skull on its back—but don’t want to just place a skull over a moth design, try integrating them. This tattoo places the skull on the wings, making it an obvious skull design but without detracting from the moth element. To really play up the contrast of nature and death with your tattoo, have the skull almost coming out of the animal, rather than just being a part of it. If you opt for a lot of shading and detail, like in this piece, make sure you’re brightening it up with some white ink or negative space.
A skull with a clock element can convey wisdom, longevity, and a deep appreciation for the passage of time.

Several cranial nerves from the brain exit the skull via this opening. It is also the exit point through the base of the skull for all the venous return blood leaving the brain. The venous structures that carry blood inside the skull form large, curved grooves on the inner walls of the posterior cranial fossa, which terminate at each jugular foramen. Since the brain occupies these areas, the shape of each conforms to the shape of the brain regions that it contains. Each cranial fossa has anterior and posterior boundaries and is divided at the midline into right and left areas by a significant bony structure or opening. Each of the paired zygomatic bones forms much of the lateral wall of the orbit and the lateral-inferior margins of the anterior orbital opening (see Figure 2).
These decorations typically include colorful patterns, flowers, hearts, and other symbols. The Mexican skulls, known as calaveras or sugar skulls, hold great symbolism in traditional Day of the Dead celebrations. These elaborately decorated skulls are an integral part of the festivities and represent the celebration and remembrance of deceased loved ones. Mexican culture believes that death is a natural part of life and that during the Day of the Dead, the spirits of the deceased return to visit their families. When getting a skull tattoo, consider the angle at which you want the design to be placed.
