  2. Orbit (anatomy) - Wikipedia

    en.wikipedia.org/wiki/Orbit_(anatomy)

    The orbital contents comprise the eye, the orbital and retrobulbar fascia, extraocular muscles, cranial nerves II, III, IV, V, and VI, blood vessels, fat, the lacrimal gland with its sac and duct, the eyelids, medial and lateral palpebral ligaments, cheek ligaments, the suspensory ligament, septum, ciliary ganglion and short ciliary nerves.

  3. Accessory visual structures - Wikipedia

    en.wikipedia.org/wiki/Accessory_visual_structures

    The lacrimal apparatus is the physiological system containing the orbital structures for tear production and drainage. [3] It consists of: The lacrimal gland, which secretes the tears, and its excretory ducts, which convey the fluid to the surface of the human eye; it is a serous gland located in lacrimal fossa. It is a j-shaped gland;

  4. Preorbital gland - Wikipedia

    en.wikipedia.org/wiki/Preorbital_gland

    The preorbital gland is closed in a relaxed calf, whereas it is opened in a stressed calf. [10] One example of this is the signalling of hunger and satiety. Fawns open their preorbital glands as a signal that they are hungry, and close the gland after feeding, when they are no longer hungry. [11]

  5. Orbital septum - Wikipedia

    en.wikipedia.org/wiki/Orbital_septum

    Orbital septum acts as a physical barrier that prevents the infection of the anterior part of the eye spreading posteriorly. For example, preseptal cellulitis mainly infects the eyelids, anterior to the orbital septum. Meanwhile, orbital cellulitis is located posterior the orbital septum, due to infections spreading from the ethmoidal sinuses.

  7. Orbital fascia - Wikipedia

    en.wikipedia.org/wiki/Orbital_fascia

    The Orbital Fascia forms the periosteum of the orbit. It is loosely connected to the bones and can be readily separated from them. Behind, it is united with the dura mater by processes which pass through the optic foramen and superior orbital fissure , and with the sheath of the optic nerve.

  8. Human eye - Wikipedia

    en.wikipedia.org/wiki/Human_eye

    The approximate field of view of an individual human eye (measured from the fixation point, i.e., the point at which one's gaze is directed) varies by facial anatomy, but is typically 30° superior (up, limited by the brow), 45° nasal (limited by the nose), 70° inferior (down), and 100° temporal (towards the temple).

  9. Tarsus (eyelids) - Wikipedia

    en.wikipedia.org/wiki/Tarsus_(eyelids)

    The attached or orbital margins are connected to the circumference of the orbit by the orbital septum. The lateral angles are attached to the zygomatic bone by the lateral palpebral raphe. The medial angles of the two plates end at the lacrimal lake, and are attached to the frontal process of the maxilla by the medial palpebral ligament).
