3
The membrane in the middle ear, which vibrates when it receives sounds and transmits the vibration to the inner ear through the chain of ossicles.
4
Organs that receive responses from coordination systems and carry them out. Muscles and glands are effectors.

A cell that forms nervous tissue.
16
The ingestion of an excessive amount of a drug or medicine which the body is unable to process, and which can be lethal.
17
Cells that are specialised to detect stimuli and send that information to the coordination centres.
18
Simple responses that occur automatically and are controlled by the spinal cord.
19
