SENSE OF VISION (EYE)

Sense of vision
SENSING END IS THE ORGAN-ORGAN TYPE RECEIVE devoted to certain stimuli
SOME IMPRESSIONS FROM ARISING OUT OF SIGHT SHALL INCLUDE, HEARING, taste, PENGHIDU

Sense of vision (EYE)
EYE FUNCTION
BEAMS OF LIGHT ON stimulation-mediated retinal optic nerve fibers, delivers to the center stimulus is to be interpreted SIGHT IN BRAIN

 

The position of the iris is protected behind the cornea and in front of the lens, the iris is the colored circle located around the eyeball. The retina is the eye line of the back where the vision processed. NOT iris Retina.

lOrbital cavity

IS eye socket that looks like Cone

CONSIST : 

- Os frontalis - Os etmoidalis

- Os zigomatikum - Os palate

- Os slenoidal - Os lacrimal

 

SUPERSILIUM (eyebrows)

  fx: AS THE EYE AND PROTECTOR    BEAUTY

lIS: Two pieces of thick skin that curved covered by fur

Palpebra (eyelids)

l

- Consists of the eyelids:

- Top

- Under

- Function palpebra: eye protection

 

- Upper eyelid consists of:

Muskulus palpebra superior levator

    - The petals are folded (Tarsus).

In the second tarsus are:

gland tarsalia

sebaceous

sweat

LAKRIMARIS apparatus (TEARS)

Produced by:

Lakrimalis superior and inferior glands

The process:

Duct ekskretorius lakrimaris

•

Sakus conjunctiva

Through the brick front of the ball

Central angle of the eyeball

Lakrimalis canal

Suktus nasolakrimalis

Inferior meatus

Muskulus OKULI (MUSCLE EYE)

l

-M. SUPERIOR PALPEBRALIS inferior levator (LIFT eyelids)

-M. ORBIKULARIS OKULI * EYE RING (CLOSE EYE)

-M. OKULI inferior rectus AROUND EYES * (CLOSE EYE)M. Medial rectus OKULI * AROUND-EYES (EYES MOVE IN / BULBS EYE)

-M. Obliques OKULI inferior (EYE BALL TO MOVE INTO THE BOTTOM)

l-M. Obliques OKULI SUPERIOR (EYES TURN TO UP, DOWN AND OUT)

l

→ ON Strabismus (squint) NOT CAUSED Imbalances / PARALISE paralysis FUNCTIONS FROM WRONG ONE EYE MUSCLE

l 

Conjunctiva

l

Cornea SMOOTH-SURFACE lining the eyelids (conjunctiva palpebra)-AND THEN ON THE FRONT everted EYE BALL (KONJUNGIVA BULBI / ocular)

LIGHT SETTINGS

lPupil

(The entry of light into the eye)

Controlled by: Autonomic nervous

Bright light (pupil smaller)

Where: circular muscle / kontriktor contracting and

form a smaller ring: Sympathetic nerve

Dark light (pupil dilated)

The light was dark where the radial muscle memendekmenyebabkan measuring pupil increases:

parasympathetic nerves

Focusing LIGHT BEAMS

Refraction: Deflection of a light beam

When a light beam on curved surfaces with greater density, the direction of refraction depends on the angle curvature

Convex lens (convex)

Cause: convergence / unification of the light beam

Concave lens (concave)

Cause divergence (spread) light beam

Refraction EYE FUNCTION

lFALL LIGHT IN THE EYE → SHADOW location Focused on the retina → penetrate & AMENDED AGENCY KORNE ALENSA AQUES & vitreous → refract and focus on the retina united CATCH SHADOW OF A SHADOW POINT focused
