    This neurotransmitter is a cousin to GABA.

    Explanation
    Glutamate is a neurotransmitter that is closely related to GABA (gamma-aminobutyric acid). Both glutamate and GABA are involved in the regulation of neuronal activity in the brain. While GABA acts as an inhibitory neurotransmitter, reducing neuronal activity, glutamate acts as an excitatory neurotransmitter, increasing neuronal activity. They both play important roles in various brain functions, such as cognition, memory, and the regulation of mood and emotions. Therefore, glutamate can be considered a cousin to GABA in terms of their similar functions and involvement in neurotransmission.

    Decreases the likelihood of messages being sent from one neuron to the next.

    • A.

      Inhibitory

    • B.

      Excitatory

    Correct Answer
    A. Inhibitory
    Explanation
    Inhibitory neurotransmitters decrease the likelihood of messages being sent from one neuron to the next. They work by hyperpolarizing the postsynaptic membrane, making it less likely for an action potential to be generated. This inhibition helps regulate and control neural activity, preventing excessive or unwanted signaling. In contrast, excitatory neurotransmitters increase the likelihood of messages being sent by depolarizing the postsynaptic membrane and promoting the generation of action potentials.

    Muscarinic receptors are

    • A.

      Excitatory

    • B.

      Inhibitory

    Correct Answer
    B. Inhibitory
    Explanation
    Muscarinic receptors are inhibitory. These receptors are a type of acetylcholine receptor found in the central and peripheral nervous system. When acetylcholine binds to muscarinic receptors, it inhibits the activity of the target cell, leading to a decrease in neuronal activity. This can result in various physiological effects, such as decreased heart rate, smooth muscle relaxation, and decreased glandular secretion.

    The _______________________ of dopamine receptors in _____________________  _________ contribute to Parkinson's symptoms

    Correct Answer
    Degeneration
    Substantia Nigra
    Explanation
    Parkinson's disease is characterized by the degeneration of dopamine receptors in the brain, particularly in the substantia nigra. The substantia nigra is a region in the brain that plays a crucial role in movement control. When these dopamine receptors degenerate, it leads to a decrease in dopamine levels, which in turn results in the motor symptoms associated with Parkinson's disease, such as tremors, rigidity, and bradykinesia.

    The Catecholamine Hypothesis says

    Correct Answer
    Depression is due to too little and Mania is due to too much.
    Explanation
    The Catecholamine Hypothesis suggests that depression is caused by a deficiency of certain neurotransmitters called catecholamines, such as norepinephrine and dopamine, in the brain. On the other hand, mania is believed to be caused by an excess of these neurotransmitters. This hypothesis is based on the observation that drugs that increase the levels of catecholamines can alleviate depression, while drugs that decrease their levels can induce mania.
