Temporal lobe
• understanding • language • hearing • speech • memory • learning • sensory speech area or Wernick
Parietal lobe
• recognising sensation, body position and objects • sense of time and space • reading and comprehension area • associated with functions of other lobes
Brain stem
Regulation of heartbeats, respiration, body temperature and other essential body functions.
Cerebellum
• balance • muscular coordination • unconscious functions
Occipital lobe
Vision and integrating visual information ( colour, shape and distance )
Cerebral hemisphere
Integrating centre for high complex functions such as learning, memory and emotions
Hypothalamus

What parts is the eye made up of
Pupil Retina Optic nerve Lens Iris
What is the pupil
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.
What is the retina
The retina is a layer that contains over 100 million light sensitive cells. These cells send messages to the brain
What is the optic nerve
It joins the eye to the brain. It passes information about the image to the brain so it is seen the right way up.
What is the lens
The lens is a clear jelly-like window that helps focus the image on the back surface of the eye.
What is the iris
It is just in front of the lens. It controls the size of the pupil and it controls the colour of the persons eye.
What happens when you look at something in the distance
The ciliary body will contract and the lens will flatten
What happens when you look at objects close up
The ciliary body will relax and the lens will become more rounded.

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