Vision and Skull

The superciliary arch is part of the skull related to the sense of vision.

Temporomandibular Joint

The squamous part of the temporal bone helps form the temporomandibular joint (TMJ).

Olfaction and Skull

The nasal crest in the skull is associated with the sense of smell.

Piriform Aperture

The piriform aperture is connected to air passing during respiration via the nasal bone.

Study Notes

Skull and Sensory Functions

  • The occipital bone is responsible for the sense of vision, housing the occipital lobe of the brain.
  • The head of the mandible forms part of the temporomandibular joint (TMJ), essential for jaw movements.
  • The sense of olfaction is associated with the ethmoid bone, particularly its cribriform plate which contains olfactory foramina.
  • The maxilla contains the piriform aperture, the opening through which air passes during respiration.

Features of the Mandible

  • The mental protuberance and mental tubercle are features of the mandible, marking the chin area.

Hearing Structures

  • The temporal bone is involved in the process of hearing, housing the cochlea and semicircular canals.
  • The mastoid process is a prominent feature of the temporal bone, serving as an attachment point for neck muscles.

Foramen and Sutures

  • The foramen magnum is associated with the medulla oblongata, allowing it to connect with the spinal cord.
  • The squamous suture separates the parietal and temporal bones of the skull.

Canals and Transmissions

  • The optic canal transmits the optic nerve and ophthalmic artery, crucial for vision.
  • The zygomatic process is found on the temporal bone, contributing to the formation of the zygomatic arch.
  • The foramen ovale transmits the mandibular nerve (V3), a branch of the trigeminal nerve.
  • The inferior nuchal line is associated with the attachment of muscles such as the trapezius.
  • The carotid canal allows the passage of the internal carotid artery, supplying blood to the brain.
  • The mandible contains the condylar process, articulating with the temporal bone at the TMJ.
  • The jugular foramen is associated with the internal jugular vein and cranial nerves IX, X, and XI, crucial for head and neck function.
