Select the best answer or answers from the choices given: An IPSP is inhibitory because (a) it hyperpolarizes the postsynaptic membrane, (b) it reduces the amount of neurotransmitter released by the presynaptic terminal,(c) it prevents calcium ion entry into the presynaptic terminal, (d) it changes the threshold of the neuron.

Give Explanation Solution (no need Handwritten)

Identify the charges (positive/negative) that appear on the inside AND the outside of an axon while at resting state. Explain 2 factors that contribute to the maintenance of this resting state.

The axon of neurons contains microtubules with the minus end situated toward the cell body and the plus end situated toward the end of the axon.  Neurotransmitters are transported in vesicles carried by motor proteins.  A neuron missing which of the following motor proteins would be unable to secrete neurotransmitters in this way? Group of answer choices: Myosin Kinesin Dynein

Describe two different ways in which we can induce reorganization/plasticity in primary motor cortex.

Binding of neurotransmitter to the motor end plate leads to depolarization because the neurotransmitter: a) opens ligand-gated sodium channels. b) opens voltage-gated sodium channels. c) opens ligand-gated potassium channels. d) opens voltage-gated potassium channels.

Jane is wishing to artificially stimulate neurotransmitter release by a motor neuron. She should be able to do this by electrically activating the neuron (TRUE or FALSE) and/or by injecting potassium ions into the synaptic terminal/knob region (TRUE or FALSE).

Which of the following options shows the pathway of a nervous signal from the tip of your finger sensing a hot object leading to the ultimate movement of your hand away from the object?   receptor --> sensory neuron --> interneuron --> motor neuron --> effector   receptor --> motor neuron --> interneuron --> sensory neuron --> effector   sensory neuron --> receptor --> interneuron --> motor neuron --> effector   sensory neuron --> receptor --> interneuron --> effector --> motor neuron   receptor --> sensory neuron --> interneuron --> effector --> motor neuron
