The nervous system, neurons and synaptic transmission

Name one type of neuron and briefly explain its function.

Explain the process of synaptic transmission. Refer to excitation in your answer.

Which of the following neurons carries electrical impulses towards the brain?

Shade one box only.

A Interneuron

B Motor neuron

C Relay neuron

D Sensory neuron

Describe the divisions of the nervous system.

Describe the structure and function of a neuron.

Zapurpain acts like an inhibitory neurotransmitter at the synapse.

Explain how Zapurpain might affect the process of synaptic transmission through inhibition.

Figure 1 shows three different types of neuron. Use the letters from Figure 1 to answer the following questions.

1 0. Which neuron is only found in the brain/visual system/spinal cord?

1 0. Which neuron carries nerve impulses from the brain/spinal cord to muscles/glands?

1 0. Which neuron carries nerve impulses between neurons?

Give one difference between the autonomic nervous system and the somatic nervous system.

Name the types of neurons labelled A, B and C on Figure 1 below. Write your answers in the boxes provided.

Information can only travel in one direction at a synapse.

Explain why neurons can only transmit information in one direction at a synapse.

Explain the process of synaptic transmission.
