What makes up the central nervous system? | brain and spinal cord. |
What is the function of the nervous system? | To control the body by sending and receiving information by electrical impulses. |
What are the three main parts of the brain? | Cerebrum, cerebellum and the medulla. |
What is the function of the cerebrum? | Controls memory and conscious thought. |
What is the function of the cerebellum? | Controls balance. |
What is the function of the medulla? | Controls breathing and heart rate. |
What are the three types of neurons? | Sensory, relay and motor neurons. |
Which is the type of nerve only found in the CNS? | Relay nerve. |
How do nerve cells communicate with each other? | By the diffusion of chemicals across the synapse (gap) between two neurons. |
What is the function of the reflex arc? | Protection from harm. |
What are the features of reflex arc? | Fast and simple action that does not involve the brain. |
What is reflex arc made up of? | sensory receptors, sensory nerve, relay nerve, motor nerve, effector organ. |
What are the two types of effector organ? | A muscle or a gland. |
What is a synapse? | Synapse is a gap between neurons |
What are endocrine glands? | Organs that produce hormones. |
What are hormones? | Chemical messengers that travel in the blood to a target organ. |
Name three examples of an endocrine gland? | pancreas, testes, ovaries. |
What is a target tissue? | Target tissue has receptors that can bind a specific hormone. |

Production of which hormone goes wrong in diabetes? | insulin. |
What happens to blood sugar levels in diabetics? | Blood sugar remains high as there is no or not enough insulin. |
