Study Notes

Head Anatomy

The head can be divided into 12 regions: frontal, parietal, occipital, temporal, auricular, orbital, nasal, infraorbital, zygomatic, buccal, oral, and mental.
The frontal region includes the forehead and the area superior to the eyes.
- Supraorbital ridge: Directly inferior to each eyebrow, aka, superciliary ridge.
- Glabella: The smooth elevated area between the eyebrows
- Frontal Eminence: The prominence of the forehead
The parietal and occipital regions are covered by the scalp.
The temporal region contains the temple, the superficial side of the head posterior to each eye.
The auricular region is located on each side of the head and includes the external ear.
The orbital region is on each side of the head and contains the bony socket of the eye.
- Includes the sclera, the white area of the eye.
- Iris: The colored area of the eye.
- Pupil: The opening in the center of the iris, appearing black.
The nasal region includes the nose, the bony projection in the middle of the face.
The infraorbital region is the area directly below the orbit, contains the infraorbital foramen where blood vessels and a nerve pass through.
The zygomatic region is the cheekbone. It is a bone that helps to form the cheek and the lateral wall of the orbit.
Temporomandibular joint: It is where the upper skull forms a joint with the lower jaw.
The buccal region is the soft tissue of the cheek.
- Masseter muscle: Can be felt when the patient clenches their teeth; found in the buccal region of the head.
The oral region is the mouth.
The mental region is the chin region.
- The mental protuberance is the prominence of the chin.
- The labiomental groove is located between the lower lip and the chin.
The vertical dimension of the face can be divided into three sections.
- The loss of height in the lower third can occur due to aging and periodontal disease.

Anatomy of the Ear

The middle ear is an air-filled space within the temporal bone, lined with mucous membranes.
- It transmits vibrations from the tympanic membrane to the inner ear.
The inner ear is responsible for sound detection and balance.
- It consists of the cochlea, which is dedicated to hearing.
- It also consists of the vestibular system, which is dedicated to balance.

Neck Anatomy

The neck is a complex area, and it is important to be familiar with the major structures that make up this area.
The neck regions include:
- Hyoid region: (above the thyroid cartilage)
- Thyroid region: (the thyroid cartilage)
- Laryngeal region: (the trachea)
- Cervical region:(bones between the head and neck)
- Submandibular region: (under the jaw)
