Iris

Answer 6

Coloured structure surrounding the pupil

Question 7

Lens

Answer 7

Flexible tissue whose job is to change shape in order to bend light beams

Question 8

Sclera

Answer 8

Outer layer of the eye
Protects the eye

Question 9

Retina

Answer 9

Inner layer of eye
React to light hitting them

Question 10

Ciliary body

Answer 10

The ring tissue at the front of the eye
Connected to the lens

Question 11

Rod and cone cells

Answer 11

Rod are sensitive to light but not change of colour
Cones sensitive to different colours but are not responsible for colour vision

Question 12

Choriod

Answer 12

Layer of tissue between the retina and the sclera
Contains lots of blood vessels

Question 13

What colour do animals see

Answer 13

Cone cells let them dectect blue and green

Question 14

Outer ear

Answer 14

Pinna- visible portion of the ear that’s helps direct sound into the ear

Question 15

Ear canal (auditory meatus )

Answer 15

Passageway that connects pinna to the middle ear

Question 16

Middle ear

Answer 16

•Tympanic membrane- ear drum, very thin surface connected to the ear canal
•malleus- hammer shaped, the first three small bones, attached to ear drum
•incus- anvil shaped bone, sits between and connected to melleus and stapes
•stapes - stirrup shaped bone, connected to incus and oval window

Question 17

Middle ear fact

Answer 17

Also connected to the throat

Question 18

Inner ear

Answer 18

•Oval window- connects the middle ear to the inner ear. Vibrations from stapes causes oval window to vibrate
•round window- allow the fluid within the cochlea space to move
•semi-circular canals- part of ear control balance nothing to do with hearing
•cochlea- structure looks like snail shell. Vibrates when the oval window vibrates. Central organ of inner ear

Question 19

Organ of corgi

Answer 19

Attached to the membrane in cochlea consists of speacil cells with hair- like projections all along with membrane

Question 20

Nose

Answer 20

Nasal chambers - the spaces leading from the nostrils all the way to the top of the throat
•turbinates- network of bone, tissue and blood vessels shaped like shells that air passes through during breathing
•olfactory nerve - made up of rector cells. Back of the nose. Rector cells passes air through that is breathed in
•olfactory bulb - able to organise different smells but sends information to the cerebral cortex in the brain for further processing

Question 21

Taste

Answer 21

Taste buds- collection of cells located in the mouth. On the tongue and soft palate.
•palate- roof of mouth which separates nasal chambers from the mouth
•hard palate- towards the front of the roof of the mouth. Made of bones that are part of the skull
Soft palate- towards the back of the top of the mouth. Made of muscle and tissue is able to move

Question 22

Extended hard palate

Answer 22

Allows animals to chew and breathe

Question 23

Tastes and taste buds

Answer 23

Allow the animal to know if anything is dangerous

Question 24

Touch

Answer 24

Also known as tactile or somatosensory system

Question 25

Speacil nerve cells

Answer 25

Skin receptors near the surface of the skin that turn information about touching into electrical signals

Question 26

Three main types of the skin receptors

Answer 26

Mechanoreceptors- respond to gentle normal touch pressure
• thermoreceptors- detect temperature
Nociceptors- pain receptors respond the sensations

Question 27

Optic disc eye

Answer 27

The nerve begins and leaves the eye causing the light sensitive cells to go

Question 28

Optic nerver eye

Answer 28

Made of nureons which transport signals received at the retina to the brain

Question 29

Jacob’s organ

Answer 29

Located in three hard palate under the nasal cavity.
Regulates hormones in body.
Plays an impoimportant role in mating
Detect predators and prey’s
