Neurophysiology Quiz

What is the primary function of the autonomic nervous system (ANS)?

• Innervates skeletal muscle

• Regulates smooth muscle and glands

• Processes sensory information

• Controls voluntary movements

Which neurotransmitter is released by adrenergic neurons?

• Acetylcholine

• Dopamine

• Norepinephrine

• Serotonin

Where are sympathetic ganglia primarily located?

• In the spinal cord

• In the paravertebral chain

• Near the effector organs

• In the brain

What type of receptors are α1 receptors?

• Non-responsive

• Sensory

• Excitatory

• Inhibitory

Which division of the ANS originates in the craniosacral region?

• Somatic nervous system

• Enteric nervous system

• Parasympathetic nervous system

• Sympathetic nervous system

What is the primary role of the adrenal medulla?

• Controls digestion

• Regulates blood pressure

• Secretes catecholamines

• Secretes acetylcholine

Which type of receptors are activated by acetylcholine?

• Nicotinic receptors

• Muscarinic receptors

• Adrenergic receptors

• Both nicotinic and muscarinic receptors

What is the function of the medulla in the autonomic centers?

• Regulates temperature

• Controls respiratory functions

• Processes visual information

• Coordinates motor activity

Which type of sensory receptor responds to mechanical forces?

• Mechanoreceptors

• Thermoreceptors

• Chemoreceptors
