Circadian rhythms correct answer: 24-hour biological process that influences regulatory functions such as the sleep/wake cycle, body temperature, hormonal and neurotransmitter secretions First-generation (conventional, typical) antipsychotics correct answer: Decrease dopamine They are effective in the treatment of positive symptoms but not negative symptoms (Halter 676) Limbic system correct answer: Part of the brain that is related to emotions (Halter 677) Neurons correct answer: S...

Summary NSG 552 Psychopharmacology Exam 1 Study Guide LATEST 2024. DOPAMINE • Dopamine belongs to the family of catecholamines. It is a neurotransmitter. • Hormones, Epinephrine and Norepinephrine (other catecholamines) are derived from Dopamine • Dopamine plays a significant role in learning, goal-directed behavior, regulation of hormones, motor control. DOPAMINE SYNTHESIS Phenylalanine (amino acid from diet) -> phenyalanine hydroxylase -> Tyrosine -> Tyrosine hydroxylase ...

NSC Chapter 5 Test with Complete Solutions transporters - Answer-special proteins embedded in the vesicle membrane that concentrate neurotransmitters inside the vesicle once the amino acid and amine neurotransmitters are synthesized in the cytosol and then taken up by the synaptic vesicles. voltage-gated calcium channels - Answer-following the depolarization of the terminal membrane, these channel proteins open and let in Ca++ ions; resulting elevation in the ions is the signal that causes n...

Receptors - ANSWER Norepinephrine-Adrenergic (adrenergic comes from the word adrenalin) Alpha 1-all sympathetic target organs except the heart-constrict the blood vessels and dilation of pupils Alpha 2-Presynaptic adrenergic nerve terminal-inhibits the release of norepinephrine Beta 1-Heart and Kidneys (BETA 1-ONE HEART)-increased heart rate and force of contraction, release of renin Beta 2-All sympathetic target organs-inhibits smooth muscle (BETA 2-TWO LUNGS) Beta blockers/olol's - ANS...

Direct communication between cells in physical contact with one another is accomplished through - gap junctions The lumen of the organs of the ____ system is part of the internal environment - cardiovascular The ___ secretes the hormones ___ to regulate the body's metabolism - thyroid; T3 and T4 if the cell body of a neuron becomes more permeable to potassium, which statement below best describes the graded potential that will be generated - potassium will leave the cell, causing the m...

Step 1: The Chemical Synapse An action potential arrives at the end bulb. Step 2: The Chemical Synapse Ca++ enters the presynaptic terminal. Step 3: The Chemical Synapse Ca++ interacts with the synaptic vesicle and fuses with the presynaptic membrane. Step 4: The Chemical Synapse Neurotransmitter is released and binds to the postsynaptic transmitter receptor. Step 5: The Chemical Synapse Receptor protein undergoes a change in shape that allows ions to flow. Step 6: The Chemical Synapse...

NRSC 2150 Exam 1 Review Questions and answers, VERIFIED/ how are different classes of neurons identified? via gene expression --> PROTEINS make a cell specific Criteria for a neurotransmitter 1. molecule must be synthesized & stored in the presynaptic neuron 2. molecule must be released by the presynaptic axon terminal upon stimulation 3. molecule must produce a response in the postsynaptic cell that mimics the response produced by the release of neurotransmitter from the presynapti...
