Inside the skull, the floor of the cranial cavity is subdivided into three cranial fossae (spaces), which increase in depth from anterior to posterior (see [link], [link]b, and [link]).

The main areas or points of reference when cutting hair are, the crest, interior, exterior, fringe, front, back, sides, perimeter, nape, crown and occipital. The frontal sinus is located just above the eyebrows, within the frontal bone (see [link]). A small area of the ethmoid bone, consisting of the crista galli and cribriform plates, is located at the midline of this fossa.

Toquilla straw from the toquilla palm is used for Panama hats and originates from Ecuador.

The four main face shapes, other than oval are: Now that we’ve taken the person’s face shape into consideration, we also have to look at the neck and shoulders to determine how the hairline should be cut.

Head: The bird's head is one of the best places to look for field marks such as eye color, malar stripes, eyebrows, eye rings, eye lines, and auricular patches.The crown (top) and nape (back) are also key parts of the head that can help identify a bird.

I’ll explain a little more about this later on when I’m showing the haircut. This type of hat crown is easy to recognize due to its dome-like shape. The hyoid bone is located in the upper neck and does not join with any other bone.

The frontal sinus is the most anterior of the paranasal sinuses. In a contrecoup (counterblow) fracture, the bone at the point of impact is not broken, but instead a fracture occurs on the opposite side of the skull. Let our guide take out the guesswork and break down the anatomy of a hat along with helpful tips on the different types of hat crowns and various hat fabrics you can choose from.

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. 2. artificial crown. All rights reserved.

When looking into the anterior nasal opening of the skull, only the inferior and middle conchae can be seen. It is the weakest part of the skull.

Oops! When looking into the nasal cavity from the front of the skull, two bony plates are seen projecting from each lateral wall.
These are the medial pterygoid plate and lateral pterygoid plate (pterygoid = “wing-shaped”). The nasal bone is one of two small bones that articulate (join) with each other to form the bony base (bridge) of the nose.

Cleft palate affects approximately 1:2500 births and is more common in females. On the anterior maxilla, just below the orbit, is the infraorbital foramen.

At the time of birth, the mandible consists of paired right and left bones, but these fuse together during the first year to form the single U-shaped mandible of the adult skull.

Crown: The top portion of the hat; the area above the brim that sits on your head. Located in the floor of the anterior cranial fossa at the midline is a portion of the ethmoid bone, consisting of the upward projecting crista galli and to either side of this, the cribriform plates. Open: Also referred to as a round crown, open crowns don’t feature any creases at all. Together these articulations form the temporomandibular joint, which allows for opening and closing of the mouth (see [link]). 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 right and left inferior nasal conchae form a curved bony plate that projects into the nasal cavity space from the lower lateral wall (see [link]).

The hyoid is held in position by a series of small muscles that attach to it either from above or below. The more anterior projection is the flattened coronoid process of the mandible, which provides attachment for one of the biting muscles.

Baseball caps are most often made of cotton or some sort of cotton blend. These are located just behind your eyebrows and vary in size among individuals, although they are generally larger in males. The shape and depth of each fossa corresponds to the shape and size of the brain region that each houses. The coronal suture passes across the top of the anterior skull. Brim Binding: The trim around a hat’s brim; an optional feature often using materials such as leather, silk, or grosgrain ribbon.

Because their connection to the nasal cavity is located high on their medial wall, they are difficult to drain.

The nuchal lines represent the most superior point at which muscles of the neck attach to the skull, with only the scalp covering the skull above these lines. Each side of the nasal cavity is triangular in shape, with a broad inferior space that narrows superiorly.

It is divided at the midline by the large foramen magnum (“great aperture”), the opening that provides for passage of the spinal cord. The maxillary sinuses are most commonly involved during sinus infections. The unpaired bones are the vomer and mandible bones.

Each parietal bone is also bounded anteriorly by the frontal bone, inferiorly by the temporal bone, and posteriorly by the occipital bone. Sahasrara is located at the crown of the head. Since the brain occupies these areas, the shape of each conforms to the shape of the brain regions that it contains. If the person has a long neck, width can be added to the haircut to fill in the space between the head and shoulders.

Located on the medial wall of the petrous ridge in the posterior cranial fossa is the internal acoustic meatus (see [link]).

This gap allows for communication between the nasal and oral cavities. The temporal bone forms the lower lateral side of the skull (see [link]).

There are two bony parts of the nasal septum in the dry skull.

The somewhat larger lateral pterygoid plates serve as attachment sites for chewing muscles that fill the infratemporal space and act on the mandible. The ramus on each side of the mandible has two upward-going bony projections.

The boundaries and openings of the cranial fossae (singular = fossa) will be described in a later section. The crown is a place where you will find a strong growth pattern. The lambdoid suture joins the occipital bone to the right and left parietal and temporal bones. The greater wing is best seen on the outside of the lateral skull, where it forms a rectangular area immediately anterior to the squamous portion of the temporal bone.

The paranasal sinuses are named for the skull bone that each occupies. In the cranial cavity, the ethmoid bone forms a small area at the midline in the floor of the anterior cranial fossa.

The superior nasal concha is located just lateral to the perpendicular plate, in the upper nasal cavity. The small superior nasal concha is well hidden above and behind the middle concha. It extends from the lesser wings of the sphenoid bone anteriorly, to the petrous ridges (petrous portion of the temporal bones) posteriorly. These may result in bleeding inside the skull with subsequent injury to the brain. OpenStax CNX.

These condyles form joints with the first cervical vertebra and thus support the skull on top of the vertebral column. The hyoid serves as the base for the tongue above, and is attached to the larynx below and the pharynx posteriorly. The facial bones include 14 bones, with six paired bones and two unpaired bones.

The brain case is formed by eight bones, the paired parietal and temporal bones plus the unpaired frontal, occipital, sphenoid, and ethmoid bones.
The anterior skull has the orbits that house the eyeballs and associated muscles. Describe the anterior, middle, and posterior cranial fossae and their boundaries, and give the midline structure that divides each into right and left areas. The sphenoid forms much of the base of the central skull (see [link]) and also extends laterally to contribute to the sides of the skull (see [link]). I will answer those questions a little bit later on when we’re doing the haircut. The nape is located below the occipital bone and the crown located diagonally back from the eyes, in the center of the head.

Important landmarks for the mandible include the following: The orbit is the bony socket that houses the eyeball and contains the muscles that move the eyeball or open the upper eyelid. This material is commonly used for sun hats and fedoras. It is subdivided into the facial bones and the brain case, or cranial vault ().The facial bones underlie the facial structures, form the nasal cavity, enclose the eyeballs, and support the teeth of the upper and lower jaws.

Lateral to this is the elongated and irregularly shaped superior orbital fissure, which provides passage for the artery that supplies the eyeball, sensory nerves, and the nerves that supply the muscles involved in eye movements.
