Information can only travel in one direction at a synapse.

Explain why neurons can only transmit information in one direction at a synapse.
Neurons can only transmit in one direction at a synapse because neurotransmitters that are released have a particular structure that fits perfectly into particular receptors on the post-synaptic cell. In addition, the diffusion of the neurotransmitters me

Briefly outline how excitation and inhibition are involved in synaptic transmission.
In synaptic transmission, neurotransmitters can have different effects. One of which is excitation, which increases that post-synaptic neuron's positive charge, and therefore increases the likelihood of the message being passed on. The other effect is inh

Martha was telling her friend Sanya about her recent frightening experience.

"I was walking home by myself in the dark. Suddenly, I heard footsteps behind me and I realised that someone was getting closer to me. I saw a bus at the bus stop and decided to
The autonomic nervous system controls functions such as heart rate and breathing rate, as well as stress response. It deals with involuntary actions. It can be split into the sympathetic and parasympathetic nervous systems. The sympathetic nervous system

Jeremy is digging in the garden. He feels the spade hit a rock and stops digging immediately.

Explain how sensory, relay, and motor neurons would function in this situation.
The sensory neurons in Jeremy's hand would send a message from the PNS to the CNS that Jeremy has hit a rock with the spade. Relay neurons would then connect with other neurons and they would be involved in the analysis of the sensation, and deciding how

Raoul has recently been prescribed a drug for mental illness. He looks on the internet to find out more about the drug but he does not understand the phrase 'synaptic transmission'.

Write a brief explanation of synaptic transmission in the brain to help
Transmission involves impulses crossing the synaptic cleft between one neuron and an adjacent one. Neurotransmitters are chemicals that are released from vesicles and lock onto receptor cells on the post-synaptic neuron. Some neurotransmitters increase th
