Neuroanatomy and Neurotransmitter Basics

Which anatomical plane divides the brain into front and back sections?

• Sagittal Plane

• Coronal Plane

• Horizontal Plane

• Transverse Plane

What is the primary function of the coronal plane in brain anatomy?

• Divides the brain into left and right

• Divides the brain into top and bottom

• Divides the brain into front and back

• Divides the brain into anterior and posterior

Which enzyme is responsible for breaking down dopamine?

• Choline acetyltransferase

• Glutamic acid decarboxylase

• Monoamine oxidase (MAO)

• Dopamine beta-hydroxylase

What is the role of serotonin transporter (SERT) in neurotransmitter inactivation?

• Breaks down serotonin

• Reabsorbs serotonin into the presynaptic neuron

• Converts serotonin to dopamine

• Inhibits serotonin synthesis

• Glutamic acid decarboxylase (GAD)

• Monoamine oxidase

• Dopamine beta-hydroxylase

What is the function of autoreceptors in neurotransmitter regulation?

• Synthesize neurotransmitters

• Detect excess neurotransmitter levels

• Break down neurotransmitters

• Transport neurotransmitters

Which neurotransmitter is synthesized from choline and acetyl-CoA?
