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)
