Components

(generated)

Component items:

Eye sensory data (eye-sensory)
- Eye - rods and cones (eye-edge-output -> LPC.PN.SG.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)
- Eye - inferior oblique muscle (LPC.MM.OCN -> eye-muscle-rotate-major-inferior-oblique): extorsion, elevation, abduction
- Eye - inferior rectus muscle (LPC.MM.OCN -> eye-muscle-rotate-major-inferior-rectus): depression and adduction
- Eye - medial rectus muscle (LPC.MM.OCN -> eye-muscle-rotate-major-medial-rectus): adducts the eyeball
- Eye - superior rectus muscle (LPC.MM.OCN -> eye-muscle-rotate-major-superior-rectus): elevates, adducts, and rotates medially the eye
- Eye - levator palpebrae superioris muscle (LPC.MM.OCN -> eye-muscle-rotate-major-levator-palpebrae): retracts/elevates eyelid
- Eye - superior oblique muscle (LPC.MM.TRH -> eye-muscle-rotate-minor): superior oblique, rotation in a vertical plane - looking down and up, rotation in the plane of the face
- Eye - lateral rectus muscle (LPC.HT.ABD -> 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)
- Eye - ciliary muscle - sympathetic (LAC.PN.SYM.SCG -> eye-muscle-curvature-sympathetic): to ciliary muscle to increase eye accomodation
- Eye - ciliary muscle - parasympathetic (LAC.PN.PSYM.CLG -> eye-muscle-curvature-parasympathetic): to ciliary muscle to inhibit eye accomodation
- Eye - iris sphincter muscle (LAC.PN.PSYM.EPG -> eye-muscle-pupil-close): to sphincter pupillae to close pupil
- Eye - iris dilator muscle (LAC.PN.SYM.SCG -> eye-muscle-pupil-open): to dilator pupillae to open pupil
Eyelid motor muscles (eyelid-motor)
- Eye - orbicularis oculi muscle:temporal (LPC.HT.FCM -> eye-muscle-close-conscious-orbital): orbital portion, contraction of the orbital to reduce glare
- Eye - orbicularis oculi muscle:zygomatic (LPC.HT.FCM -> 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
- Eye - orbicularis oculi muscle:palpebrale (LPC.HT.FCM -> eye-muscle-close-involuntary-palpebrale): palpebral portion, acts involuntarily, closing the lids gently; involuntary muscle to close eye
- Eye - superior tarsal muscle (LAC.PN.SYM.SCG -> eye-muscle-superior-tarsal): raise the upper eyelid
- Eye - inferior tarsal muscle (LAC.PN.SYM.SCG -> eye-muscle-inferior-tarsal): lower lid retraction
- Eye - orbitalis muscle (LAC.PN.SYM.SCG -> eye-orbitalis-muscle): protrusion of eyeball
Eye glands (eye-glands)
- Eye - lacrimal gland (LAC.PN.PSYM.SPG -> eye-tears-gland): tears
- Eye - lacrimal gland and conjunctiva receptors (eye-lacrimal-gland-conjunctiva-receptors -> LPC.PN.SG.TRG): tears
