    Introduction to the bones of the skull.
  2. Main muscles of the head and neck
    Introduction to the main muscles of the head and neck.
  3. Main arteries of the head and neck
    Overview of the arteries that supply the structures of the head and neck.
  4. Main veins of the head and neck
    Major veins of the head and neck.
  5. Main nerves of the head and neck
    Overview of the major nerves of the head and neck.

Skull

The skull is a complex arrangement of bones and serves mainly to protect your brain. Here you'll learn about the bones that define the cranium.
  1. Anterior view of the skull
    Structures seen on the anterior view of the skull.
  2. Posterior and lateral skull
    An overview of the structures seen from the posterior and lateral views of the skull

  9. Temporal bone
    Structure and landmarks of the temporal bone.
  10. Mandible
    Introduction to the structure and function of the mandible

Orbit and contents

The bony orbit is the skeletal cavity or socket which is made up of several cranial structures and surrounds the soft tissue that make up the eye.
  1. Bones of the orbit
    Introduction to the bones of the orbit.
  2. Superior and inferior orbital fissures
    Introduction to the structure and contents of the superior and inferior orbital fissures.
  3. Muscles of the orbit
    Overview of the muscles of the orbit.
  4. Neurovasculature of the orbit
    An overview of the blood vessels and nerves of the orbit.
  5. Anatomy of the eyeball
    An overview of the anatomy of the eyeball.
  6. Eyelids and lacrimal apparatus
    Overview of the structure and function of the eyelids and lacrimal apparatus.
  7. Blood vessels of the eyeball
    Arteries and veins of the eye.

Nasal region

The nasal region consists of two main structures: nose, which defines the center of the face; and nasal cavity, an air-filled space above and behind the nose.
  1. Nasal cavity
    Bones, cartilages and mucosa of the nasal cavity.
  2. Neurovasculature of the nasal cavity
    Arteries, veins and nerves of the nasal cavity.

Ear

The ear is situated bilaterally on the Human head. It is the motherboard for somatic balance and hearing. It can be divided into the outer, middle and inner ear.
  1. External ear
    Introduction to the external ear.
  2. Middle ear
    Introduction to the anatomy of the middle ear.

    Introduction to the different types of teeth and their function.
  2. Teeth names and notations
    Overview of teeth names and notations.
  3. Anatomy of the tooth
    Overview of the anatomy of the tooth.

Oral cavity

The oral cavity is an important internal area of the head and is the first part of the digestive system. It also plays a significant role in communication.

    Overview of the structures in the oral cavity and their functions.
  2. Surface of the tongue
    Overview of the surface of the tongue and the lingual papillae.
  3. Muscles of the tongue
    Overview of the extrinsic and intrinsic muscles of the tongue.
  4. Neurovasculature of the tongue
    Overview of nerves, arteries and veins that supply the tongue.

Pharynx

The pharynx is a muscular column running between the oral cavity and the esophagus. Each pharyngeal structure, including muscles and vessels, will be seen here.
  1. Pharyngeal mucosa
    Pharyngeal mucosa and related structures.
  2. Muscles of the pharynx
    Overview of the muscles of the pharynx and related structures.
