auricle

outer ear canal

eardrum

eustachian tube

cochlea

hammer

stirrup

anvil

Why do we have semi-circular canals?

1. so we can hear ourselves speak
2. to pass on vibrations
3. to keep our balance
4. all of the above

What part of the ear vibrates first?

1. semi-circular canals
2. eardrum
3. ossicles
4. cochlea

What is not a little bone in your ear?

1. hammer
2. anvil

If you loose your sense of balance, you also become deaf.

1. true
2. false

sense of smell

cells of sense of smell

nasal cavity

nostrils

Why do we have hairs in our nose?

1. to filter dirt from the air we breath
2. to hold our snots in place
3. to filter germs from the air we breath
4. to keep our brains in place

Why do we taste badly when we have a cold?

1. we do taste but because we feel ill our brain doesn’t register the flavours.
2. because the nasal cavity is full of snots and no chemicals get to the receptors
3. because the nerves are broken

Babies don’t like certain flavours because they remind them of poisonous things. What flavours would that be? And explain why..

4. muscles

How do you call the signals the sense organs send out?

Fill in the right words:
The smell of a fresh panini comes into your nose, this is called a (stimulus/impulse). Then a (stimulus/impulse) is sent through the nerves to the brain.

organs in the skin respond to temperatures that are warmer than the skin

The ends of certain nerves, letting you sense pain

Organs in the skin that respond to gentle contact

Organs in the skin that respond to temperatures that are cooler than the skin

Organs in the skin that respond to pressure

heat receptor

pain receptor

touch receptors

cold receptors

precessure receptors
