Parkinson's Disease
Parkinson's disease is neurodegenerative disorder that affects movement. Most people affected with Parkinson's disease demonstrate rigidity, slow movement, and shaking. The symptoms of Parkinson's disease occur when the cells that produce dopamine neurotransmitters die in the brain.
Explain how the signal transmission at a synapse in an individual with Parkinson's disease is different than an unaffected individual.
Describe the normal process of signal transmission at a synapse. Start with the arrival of an action potential at the axon terminal and include the name of the neurotransmitter that is affected by Parkinson's disease.
Explain how the process is different in individuals affected with Parkinson's disease.

- Describe the evidence showing that axons seek specific targets.arrow_forwardWhich of the following statements is true? Chemical messengers within cells are always the main determinant of the effector response. Dual innervation is always present in all organs and glands; one branch enhances the function or secretion, while the other branch inhibits it. The beating of the heart is regulated only by the sympathetic division. Some blood vessels contain alpha adrenergic receptors that cause vasoconstriction in the presence of epinephrine, whereas others have beta adrenergic receptors that cause vasodilation in the presence of epinephrine.arrow_forwardDescribe the differences between cooperative effects and antagonistic effects in dual innervation of target organs.arrow_forward

- Draw a chain of two neurons that synapse on one another in sequence. Label the presynaptic and postsynaptic ends of each neuron, the cell bodies, dendrites, axons, axon hillock and axon terminals, location of voltage gated Ca²+ channels, location of voltage gated Na+ channels, location of voltage gated K* channels, location of Na*/ K+ pumps, location of neurotransmitter storage, location of neurotransmitter receptors. Consider your drawing and describe the function of neurons. Include an explanation why neurons are considered polarized cells and how this relates to their function. (Polarized here is not referring to membrane potential as all cells have a membrane potential). This means you will need to explain the location of different channels in the neuron and the relationship of the channels to the function of a neuron.arrow_forwardExplain the difference between slow and fast chemical transmission. Fig. 8.23arrow_forwardWhat type of synaptic potential (if any; be sure to indicate if any modification is occurring as well) would occur if: a.) An MAO inhibitor type of antidepressant is functioning at an active dopaminergic synapse that increases the rate of sodium flowing into the cell. b.) Prozac is present at an active serotonin synapse where receptor activation increases the flow of potassium out of the cell.arrow_forward
- Multiple sclerosis (MS) is a disorder that causes the destruction of myelin sheaths surrounding neurons. People with MS display many symptoms, including slurred speech, double vision, and poor muscle coordination. What is the direct effect of MS on nerve impulse transmission? Select one: The movement of impulses along neurons is slower than normal. Dendrites cannot be stimulated by acetylcholine, therefore impulses are not generated in neurons. The threshold level of stimulation for neurons is greater than normal. Axons cannot sectete acetylcholine, therefore impulses are not able to travel across synapses. Oarrow_forwardThe Generation, Transmission and Integration of Neural Signals Direction: Fill the blanks with the correct word that completes the paragraph. (1) ______________________ are a group of endogenous chemicals responsible for signaling between neurons and other cells (there is very little direct “electrical” connection between neurons). Thus, signaling of the nervous system is a bioelectrochemical process affected by neurotransmitters. Neurotransmitters act on proteins called (2) _______________, which are found on cell membranes in synapses. (3) _______________ are very narrow gaps (20–50 nm) between neurons allowing for chemical transmission via neurotransmitters. The binding of neurotransmitters to pre- and post-synaptic receptors results in changes in the polarization of the cell. Neurotransmitter actions that increase the likelihood of initiating an action potential are called (4) __________________ (EPSPs) while those that reduce the likelihood of an action potential are termed (5)…arrow_forwardREAD: They key to large-scale communication in the entire nervous system is the ability to pass nerve impulses on a small scale from one neuron to the next so that signals can be transmitted throughout the entire body. The junction between two neurons is called a synapse, and is the critical space that mediates the transfer of a signal from the presynaptic neuron (the sender) to the postsynaptic neuron (the receiver) or even an effector cell (like a gland or muscle cell.) You circled a synapse in Model 1. Synapses can be electrical or chemical. Electrical synapses transmit electrical signals via gap junctions. A channel protein connects the cytoplasm of two adjacent neurons so that ions can flow directly from one cell to another to pass on the signal. However, the most common type of synapse is a chemical synapse. These utilize chemical signals, called neurotransmitters, to transmit the signal across the synaptic cleft. This is a slower process, but allows for much greater precision…arrow_forward
