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...

Based on your excellent understanding and extensive knowledge of chemical synaptic transmission, EXPLAIN what would happen in response in each hypothetical situation below….Assume you have an experimental set-up with two neurons connected via a chemical synapse – Neuron A is presynaptic and Neuron B is postsynaptic. Also assume that there is a stimulating electrode in Neuron A that brings it to threshold and produces an EPSP in Neuron B. In your answers, include all relevant events between this stimulus and...

Neuron Signaling and Muscle Contraction 1) “Dissect” the various parts of an action potential by describing the status (active or nonactive) of the voltage-gated sodium channel, voltage-gated potassium channel, sodium/potassium pump, and overall voltage and/ or voltage range (in millivolts, or mV) for each of the following. A) Resting membrane (prior to the initiation of an action potential) B) just before threshold to just after threshold (Depolarization) C) Rising phase of the action potential D) Falling phase of the action...

A 35 year old female presents with a history of several episodes, each separated by several months, in which she experiences brief periods of physical weakness, clumsiness of the legs and hands, visual disturbances, and mood swings. Her weakness is most prominent in the lower extremities. CT scans show evidence of multiple lesions in the white matter of the brain and spinal cord. During her last episode, there were increasing neurological deficits due to an increasing number of disseminated lesions....
