Acetylcholine is a neurotransmitter that is released into the space between motor neurons and muscles, as well as between some neurons of the brain. The release of acetylcholine from a neuron causes a conformational change in a transmembrane protein of the adjacent cell to allow an influx of Na+. From your understanding of cell signaling, what type of receptor is involved in this example? (1 mark) Explain your answer by matching the components of this question to what you know about the receptor type you have named

Complete the following statements to summarize the role of neurotransmitters. Not all choices will be used. stimulus synaptic cleft Serotonin Acetylcholine synaptic division receptor released neurons synaptic vesicles signals Neurotransmitters transmit between neurons to organs, and from neurons to muscles. , from neurons to glands, from Because an action potential cannot cross the synapse between neurons, neurotransmitters aid in signaling between neurons. The neurotransmitter is by the sending neuron, where it has been stored in at the axon terminal. and...
The right answer is (D)
Please explain. I don't understand how K+ could be effluxing rather
than influxing
Passage IV (Questions 114-117) Electrical impubses are transferred from one neuron to another via a synapse. Synapses can be electrical or chemical. In response to an electrical stimalus such as an action potential the presynaptic neuron in a chemical synapse releases a neuro- transmitner across a small space between the two neurons known as a symaptic cief. Neurotransmitiers may have excita- ory...

Hypothalamic neurons play a role in the release of tropic hormones which function to the brain and endocrine systems. 36. A G-protein linked receptor typically works slower because its has more steps and it has a greater effect. 37. After an axon potential is transmitted down the axon to the axon terminal, a massive amount of calcium into the neuron. 38. The postsynaptic neuron...

How do neurons conduct information? (Please note: this question refers only to events occurring during the time from the receipt of an external signal by a single neuron to the time this information is relayed to the next neuron or muscle. It does not include anything relating to the initial sensory neuron that stimulated the neuron in question, or the subsequent neuron or muscle that this neuron stimulates.) a. What kind of protein “senses” incoming information at the post-synaptic membrane?...
The Brain on Mind Altering Drugs Psychoactive drugs alter brain function by acting at synapses in the brain, where they may mimic, enhance, or block the effects of natural signaling molecules (neurotransmitters). The neurotransmitter dopamine plays a particularly important role in creating the dependency aspect of both drug and behavioral addictions. Natural behaviors which enhance survival and/or reproduction, such as eating or engaging in sex, result in a surge of dopamine. Normally, this response helps individuals learn to repeat beneficial...
Which of the following statements are accurate? Select all that apply Interneurons are responsible for analysis of stimuli and forming a circuit to respond to the stimuli. Interneurons can interact (e.g. stimulate) with muscle cells or glands. The peripheral nervous system is able to carry information to and from the central nervous system. Nerves typically collect sensory information such as light, touch, or blood pressure. Interneurons are a type of sensory neuron. Which of the following statements are accurate? select...
