Components

(generated)

Component items*:
*Eye sensory data* (*eye-sensory*)

* Eye - rods and cones (eye-edge-output -> LPC.FD.RT): after on-center/off-center edge extraction and zipping 100:1
* Eye - somatic receptors (eye-somatic -> LPC.PN.SG.TRG): eye -> semilunar ganglion/ophthalmic -> PTR
* Eye - visceral receptors (eye-visceral -> LPC.MM.MSTR): eye -> semilunar ganglion/ophthalmic -> STR, proprioception

*Eye rotation motor muscles* (*eye-rotation-motor*)

* [- inferior oblique muscle] (BrainRegionLPC_MM_OCN LPC.MM.OCN -> HumanMusclesHead eye-muscle-rotate-major-inferior-oblique): extorsion, elevation, abduction
* [- inferior rectus muscle] (BrainRegionLPC_MM_OCN LPC.MM.OCN -> HumanMusclesHead eye-muscle-rotate-major-inferior-rectus): depression and adduction
* [- medial rectus muscle] (BrainRegionLPC_MM_OCN LPC.MM.OCN -> HumanMusclesHead eye-muscle-rotate-major-medial-rectus): adducts the eyeball
* [- superior rectus muscle] (BrainRegionLPC_MM_OCN LPC.MM.OCN -> HumanMusclesHead eye-muscle-rotate-major-superior-rectus): elevates, adducts, and rotates medially the eye
* [- levator palpebrae superioris muscle] (BrainRegionLPC_MM_OCN LPC.MM.OCN -> HumanMusclesHead eye-muscle-rotate-major-levator-palpebrae): retracts/elevates eyelid
* [- superior oblique muscle] (BrainRegionLPC_MM_TRH LPC.MM.TRH -> HumanMusclesHead eye-muscle-rotate-minor): superior oblique, rotation in a vertical plane - looking down and up, rotation in the plane of the face
* [- lateral rectus muscle] (BrainRegionLPC_HP_ABD LPC.HP.ABD -> HumanMusclesHead eye-muscle-rotate-vestibular): lateral rectus, quick turn to the right -> compensatory reflex turning of two eyes to the left

*Eye pupil and accomodation motor muscles* (*eye-pupil-motor*)

* [- ciliary muscle - sympathetic] (BrainRegionLAC_PN_SYM_SCG LAC.PN.SYM.SCG -> HumanMusclesHead eye-muscle-curvature-sympathetic): to ciliary muscle to increase eye accomodation
* [- ciliary muscle - parasympathetic] (BrainRegionLAC_PN_PSYM_CLG LAC.PN.PSYM.CLG -> HumanMusclesHead eye-muscle-curvature-parasympathetic): to ciliary muscle to inhibit eye accomodation
* [- iris sphincter muscle] (BrainRegionLAC_PN_PSYM_EPG LAC.PN.PSYM.EPG -> HumanMusclesHead eye-muscle-pupil-close): to sphincter pupillae to close pupil
* [- iris dilator muscle] (BrainRegionLAC_PN_SYM_SCG LAC.PN.SYM.SCG -> HumanMusclesHead eye-muscle-pupil-open): to dilator pupillae to open pupil

*Eyelid motor muscles* (*eyelid-motor*)

* [- orbicularis oculi muscle:temporal] (BrainRegionLPC_HP_FCM LPC.HP.FCM -> HumanMusclesHead eye-muscle-close-conscious-orbital): orbital portion, contraction of the orbital to reduce glare
* [- orbicularis oculi muscle:zygomatic] (BrainRegionLPC_HP_FCM LPC.HP.FCM -> HumanMusclesHead eye-muscle-close-conscious-lacrimal): lacrimal part (tensor tarsi), conscious muscle to close eye; draws the eyelids and the ends of the lacrimal canals medialward and compresses them against the surface of the globe of the eye; compresses the lacrimal sac
* [- orbicularis oculi muscle:palpebrale] (BrainRegionLPC_HP_FCM LPC.HP.FCM -> HumanMusclesHead eye-muscle-close-involuntary-palpebrale): palpebral portion, acts involuntarily, closing the lids gently; involuntary muscle to close eye
* [- superior tarsal muscle] (BrainRegionLAC_PN_SYM_SCG LAC.PN.SYM.SCG -> HumanMusclesHead eye-muscle-superior-tarsal): raise the upper eyelid
* [- inferior tarsal muscle] (BrainRegionLAC_PN_SYM_SCG LAC.PN.SYM.SCG -> HumanMusclesHead eye-muscle-inferior-tarsal): lower lid retraction
* [- orbitalis muscle] (BrainRegionLAC_PN_SYM_SCG LAC.PN.SYM.SCG -> HumanMusclesHead eye-orbitalis-muscle): protrusion of eyeball

*Eye glands* (*eye-glands*)

* [- lacrimal gland] (BrainRegionLAC_PN_PSYM_SPG LAC.PN.PSYM.SPG -> HumanMusclesHead eye-tears-gland): tears
* Eye - lacrimal gland and conjunctiva receptors (eye-lacrimal-gland-conjunctiva-receptors -> LPC.PN.SG.TRG): tears
