  2. Suspensory ligament of eyeball - Wikipedia

    en.wikipedia.org/wiki/Suspensory_ligament_of_eyeball

    This ligament is responsible for maintaining and supporting the position of the eyeball in its normal upward and forward position within the orbit, and prevents downward displacement of the eyeball. [2] It can be considered a part of the bulbar sheath. [3] It is named for Charles Barrett Lockwood.

  3. Zonule of Zinn - Wikipedia

    en.wikipedia.org/wiki/Zonule_of_Zinn

    The zonule of Zinn (/ ˈ t s ɪ n /) (Zinn's membrane, ciliary zonule) (after Johann Gottfried Zinn) is a ring of fibrous strands forming a zonule (little band) that connects the ciliary body with the crystalline lens of the eye. [1]

  4. Intraocular muscles - Wikipedia

    en.wikipedia.org/wiki/Intraocular_muscles

    They're different to the extraocular muscles that are outside of the eye and control the external movement of the eye. [2] There are three intrisic ocular muscles: the ciliary muscle, pupillary sphincter muscle (sphincter pupillae) and pupillary dilator muscle (dilator pupillae). [1] [2] All of them are smooth muscles. [2]

  5. Accessory visual structures - Wikipedia

    en.wikipedia.org/wiki/Accessory_visual_structures

    The orbit is the cavity or socket of the skull in which the eye and its appendages are situated. In the adult human, the volume of the orbit is 30 millilitres (1.06 imp fl oz; 1.01 US fl oz), of which the eye occupies 6.5 ml (0.23 imp fl oz; 0.22 US fl oz). [4] The orbit helps in smooth rotation of the eyeball.

  6. Lens (vertebrate anatomy) - Wikipedia

    en.wikipedia.org/wiki/Lens_(vertebrate_anatomy)

    The lens is located towards the front part of the vertebrate eye, called the anterior segment, which includes the cornea and iris positioned in front of the lens. The lens is held in place by the suspensory ligaments (Zonule of Zinn), [1] attaching the lens at its equator to the rest of the eye [2] [3] through the ciliary body.

  7. Posterior chamber of eyeball - Wikipedia

    en.wikipedia.org/wiki/Posterior_chamber_of_eyeball

    The posterior chamber is a narrow space behind the peripheral part of the iris, and in front of the suspensory ligament of the lens and the ciliary processes. The posterior chamber consists of small space directly posterior to the iris but anterior to the lens.

  8. Accommodation (vertebrate eye) - Wikipedia

    en.wikipedia.org/wiki/Accommodation_(vertebrate_eye)

    In 1992, Ronald Schachar proposed a model for land based vertebrates that was not well received. [7] The theory allows mathematical modeling to more accurately reflect the way the lens focuses while also taking into account the complexities in the suspensory ligaments and the presence of radial as well as circular muscles in the ciliary body.

  9. Charles Barrett Lockwood - Wikipedia

    en.wikipedia.org/wiki/Charles_Barrett_Lockwood

    The "Lockwood's suspensory ligament" of the eye is named after him. This structure is the thickened area of contact between Tenon's capsule and the sheaths of the inferior rectus and inferior oblique muscles. This ligament is responsible for maintaining the position of the eyeball in its normal upward and forward position within the orbit.
