• unconscious functions

Question 10

Occipital lobe

Answer 10

Vision and integrating visual information ( colour, shape and distance )

Question 11

Cerebral hemisphere

Answer 11

Integrating centre for high complex functions such as learning, memory and emotions

Question 12

Hypothalamus

Answer 12

Maintains homeostasis, coordinating the nervousness and endocrine systems, secretes hormones of the posterior pituitary, and releasing factors regulating the anterior pituitary.

Question 13

Pituitary gland

Answer 13

Stores and releases hormones made by the hypothalamus and the anterior, it produces and secretes hormones regulating many body functions.

Question 14

Medulla oblongata

Answer 14

Controls automatic and homeostatic activities, such as swallowing, digestion and vomiting, breathing and heart activity

Question 15

What parts is the eye made up of

Answer 15

Pupil
Retina
Optic nerve 
Lens
Iris

Question 16

What is the pupil

Answer 16

The hole in the centre of your iris.
In the dark your pupil gets larger or dilates to let more light in so that you can see
In the bright light your pupil gets smaller so that less light gets in, so that you can see and it’s not to bright.

Question 17

What is the retina

Answer 17

The retina is a layer that contains over 100 million light sensitive cells. These cells send messages to the brain

Question 18

What is the optic nerve

Answer 18

It joins the eye to the brain. It passes information about the image to the brain so it is seen the right way up.

Question 19

What is the lens

Answer 19

The lens is a clear jelly-like window that helps focus the image on the back surface of the eye.

Question 20

What is the iris

Answer 20

It is just in front of the lens. It controls the size of the pupil and it controls the colour of the persons eye.

Question 21

What happens when you look at something in the distance

Answer 21

The ciliary body will contract and the lens will flatten

Question 22

What happens when you look at objects close up

Answer 22

The ciliary body will relax and the lens will become more rounded.

Question 23

What are the parts of the ear

Answer 23

• hammer, anvil and stirrup
• pinna
• oval window
• semi-circular canals
• auditory nerves
• cochlea
• Eustachian tube
• eardrum( tympanic membrane )
• auditory canal

Question 24

What are the hammer, the anvil and the stirrup

Answer 24

A group of three bones called the ossicles. By the time the sound wave has reached the stirrup it has been amplified to about 30 times louder than at the eardrum

Question 25

What is the pinna

Answer 25

The pinna is the visible part of the ear. Collects sound and funnels it into the auditory canal

Question 26

What is the oval window

Answer 26

The oval window is the part of the ear that the stirrup vibrates against, causing the vibrations to pas to the cochlea. It marks the boundary between the middle ear and the inner ear.

Question 27

What are the semi-circular canals

Answer 27

The semi-circular canals contain 3 sections each perpendicular to each other. They contain fluid that moves when you move. Nerves send messages to the brain which in turn reminds our muscles to keep us in balance.

Question 28

What are the auditory nerves

Answer 28

The auditory nerves send messages to the brain which then interpret sounds.

Question 29

What is the cochlea

Answer 29

The cochlea is the coiled, fluid-filled tube. The fluid passes vibrations to a layer of tiny hairs on the auditory nerves

Question 30

What is the Eustachian tube

Answer 30

It is a tube connected to our throat that helps maintain pressure between the middle and inner ear

Question 31

What is the eardrum ( tympanic membrane )

Answer 31

It is made out of a thin layer of skin and muscle. It vibrates in response to sound. It is the beginning of the middle ear.

Question 32

What is the auditory canal

Answer 32

The auditory canal connects the outer ear with the eardrum

Question 33

What is the function of the tongue in the digestive system

Answer 33

``` It help with swallowing It is a taste organ It pushes food under your teeth It keeps your teeth clean It helps with chewing ```

Question 34

What are the different taste buds and where are they positioned in your tongue

Answer 34

Circumvallate -back of tongue Foliate - back sides of tongue Fungi form - front of tongue

Question 35

What are the different parts of the

Answer 35

* frontal sinus * olfactory bulb * sphenoidal sinus * tonsil * nasal cavity * cartilage * nasal bone

Question 36

How does the nose work

Answer 36

•The cavity of the nose is lined with mucous membranes that have smell receptors connected to the olfactory bulb • the smells consists of vapours • the smell receptors interact with the vapour molecules and transmit the sensation to the brain • nose has a structure called the vomer nasal organ ( unknown function) thought to be sensitive to pheromones that influence the reproductive system • the smell receptors are sensitive to 7 types of sensations - camphor, musk, flower, mint, ether, acrid, or putrid. •
