Which type of neuron conveys messages from your brain and spinal cord to your muscles in order to control your body's movements?

• Interneuron

• Sensory

• Endocrine

• Motor

• Associative

Which type of neuron conveys messages from your brain and spinal cord to your muscles in order to control your body's movements?

• Interneuron

• Afferent

• Mirror

• Efferent

• Somatic

The function of dendrites is to...

• Receive incoming signals from other neurons

• Release neurotransmitters into the synaptic gap between neurons

• Coordinate the activation of the parasympathetic nervous system

• Control pain through the release of opiate like chemicals into the brain

• Regulate the refractory period

Which describes the main function of a Selective Serotonin Reuptake Inhibitor (SSRI), a class of medication commonly used to treat depression?

• Enhance the release of serotonin

• Slow the production of serotonin

• Stop the production of serotonin
