What's the function of the cerebrum?
The cerebrum produces voluntary movement.
Give examples of voluntary and an involuntary movements (two for each).
Voluntary: crossing the streets, responding to a questions, getting food
Involuntary: breathing, heart beating, digesting food
Our nervous system is made up of star-like shape cells called ________.
They are in charge of receiving and transmitting nerve impulses along the nervous system.

The sense of HEARING.
The ears are the organs of the sense of hearing.
The ______ ________ collects sounds.
This sound passes through the _______ _______, the ________ _________ and the three small bones called ossicles.
Then, the sounds reaches the _________ and the ________ __________. The auditory nerve sends signals to the brain.
The sense of HEARING.
The ears are the organs of the sense of hearing.
