Structure of eye

Name the part labelled 1

• cornea

• eye lens

• suspensory ligament

• iris

Answer explanation

The part labelled 1 is the suspensory ligament, which is responsible for holding the eye lens in place within the eye.

Name the part labelled 2

• cornea

• eye lens

• suspensory ligament

• ciliary muscle

Answer explanation

The part labelled 2 is the ciliary muscle, which is responsible for controlling the shape of the lens to focus on objects at different distances.

Name the part labelled 3

• cornea

• eye lens

• suspensory ligament

• conjunctiva

Answer explanation

Part labelled 3 is the eye lens, responsible for focusing light onto the retina. It helps in refracting light to form clear images on the retina.

Name the part labelled 4

• cornea

• sclera

• suspensory ligament

• conjunctiva

Answer explanation

The part labelled 4 is the sclera, which is the tough, white outer layer of the eyeball that helps maintain the shape of the eye and protect its inner components.

Name the part labelled 5

• choroid

• sclera

• suspensory ligament

• conjunctiva

Answer explanation

The correct choice is choroid because it is the part labelled 5 in the anatomy diagram provided.

Name the part labelled 6

• choroid

• sclera

• retina

• conjunctiva

Answer explanation

Part labelled 6 is the retina, which is responsible for sensing light and sending signals to the brain for visual recognition.

Name the part labelled 7

• choroid

• blind spot

• retina

• yellow spot

Answer explanation

The part labelled 7 is the yellow spot, also known as the macula lutea, which is responsible for sharp central vision and color perception.

Name the part labelled 8

• choroid

• blind spot

• optic nerves

• yellow spot

Answer explanation

The part labelled 8 is the optic nerves, which are responsible for transmitting visual information from the eye to the brain.

Name the part labelled 9

• choroid

• blind spot

• optic nerves

• yellow spot

Answer explanation

The part labelled 9 is the blind spot, also known as the optic disc, where the optic nerve exits the eye. It lacks photoreceptor cells, causing a gap in the visual field.

Name the part labelled 10

• vitreous humour

• pupil

• optic nerves

• aqueous humour

Answer explanation

The part labelled 10 is the vitreous humour, which is a clear gel-like substance that fills the space between the lens and the retina in the eye.
