• Periosteum


  The fibrous membrane covering the outer surface of bones
• Orbital Fascia


  • The periosteum of the bones that form the walls of the orbit
• Orbicularis oculi


  Muscle that controls the eyelids
• Levator palpebrae superioris


  Muscle that controls the eyelids
• Fibrous Coat


  Made up of a posterior opaque part, the sclera, and an anterior transparent part the cornea
• Optic nerve


  Enters the orbit from the middle cranial fossa by passing through the optic canal
• Ophthalmic artery


  Accompanies the optic nerve
• Medial and Lateral Check Ligaments


  Triangular ligaments that connect the medial and lateral walls of the orbit
• Sphincter Pupillae


  Muscle that constricts the pupil in the presence of bright light and during accommodation
• Lacrimal Nucleus


  Nucleus of the facial nerve that provides the parasympathetic secretomotor nerve supply
• Frontal Bone


  Bone that forms the orbital region of the eye
• Central Artery of the Retina


  Small branch that pierces the meningeal sheaths of the optic nerve to gain entrance to the nerve
• Consensual light reflex


  Tested by shining the light in one eye and noting the contraction of the pupil in the opposite eye
• Paranasal Sinuses


  Cavities found in the interior of the maxilla, frontal, sphenoid, and ethmoid bones
• Larynx


  Organ that provides a protective sphincter at the inlet of the air passages and is also responsible for voice production
• Thyrohyoid Membrane


  Connects the upper margin of the thyroid cartilage to the hyoid bone
• Extrinsic Muscles


  Muscles that move the larynx up and down during swallowing
• Infundibulum


  Anterior end of the hiatus that leads into a funnel-shaped channel, continuous with the frontal sinus
• Pituitary Gland


  Small, oval structure attached to the undersurface of the brain by the infundibulum, protected by its location in the sella turcia of the sphenoid bone
• Parathyroid hormone (PTH)


  Produced by the chief cells in the parathyroid glands, stimulates osteoclastic activity in bones, mobilizing bone calcium and increasing calcium levels in the blood
• Fibroelastic Tube


  Kept patent by the presence of U-shaped cartilaginous bar (rings) of hyaline cartilage embedded in its wall
• Ophthalmic division (V1)


  Branch of the trigeminal nerve that helps you feel sensations in your face
• Maxillary division (V2)


  Branch of the trigeminal nerve that helps you feel sensations in your face
