_____________→ receptor → coordinator → effector → response

What is a synapse? 

• A small gap at the end of a neuron that allows a signal to pass from one neuron to the next.

• The neurones and nerves

• The CNS and nerves

• The central nervous system and peripheral nervous system

What two parts make up the CNS?

• Brain and spinal cord

• Nerves and brain

• Pancreas and neurones

• Neurones and synapses

What is a receptor?

• An type of neurotransmitter.

• An organ or cell able to respond to stimulus and transmit a signal to a sensory nerve.

• An enzyme that controls nerve signalling.

• A type of hormone.

What is the job of the nervous system?

• To trigger nerves

• Helps the legs to react to its environment

• Controls temperature

• Helps all the parts of the body to communicate with each other.

State 2 ways in which the neurons are adapted for their function

• Cell body and neurotransmitters
• Synapses and myelin sheath
• They are long and branched

• Nucleus, cytoplasm and mitochondria
