Answer:
The Internal Structure of an Eye
Lens: It is a transparent, biconvex, lens of an eye. The lens is attached to the ciliary body by ligaments. The lens along with the cornea refracts light so that it focuses on the retina. ... The optic nerves carry all the nerve impulses from the retina to the human brain for perception.
Answer:
The human eye is a roughly spherical organ, responsible for perceiving visual stimuli. It is enclosed within the eye sockets in the skull and is anchored down by muscles within the sockets.
Anatomically, the eye comprises two components fused into one; hence, it does not possess a perfect spherical shape. External components include structures which can be seen on the exterior of the eye and internal components include structures present within.
External components include:
- Sclera
- Conjunctiva
- Cornea
- Iris
- Pupil
Internal components include:
- Lens
- Retina
- Optic nerve
- Aqueous Humour
- Vitreous Humour
