    Created by @sanjrecovers

    What are the layers of the meninges?

    Dura mater, arachnoid mater, pia mater.

    What causes meningitis?

    Inflammation of the meninges.

    What is the function of cerebrospinal fluid (CSF)?

    Provides protection and cushioning for the brain.

    How do the ventricles relate to CSF production?

    Ventricles contain choroid plexus that produces CSF.

    What happens during depolarization?

    Membrane potential becomes less negative, leading to action potential.

    What is the role of the sodium-potassium pump?

    Maintains ion concentration gradients across the membrane.

    How does the sympathetic nervous system (SNS) affect the body?

    Prepares the body for 'fight or flight' responses.

    What distinguishes the parasympathetic nervous system (PNS) from the SNS?

    PNS conserves energy, while SNS expends energy.

    What is the threshold of excitation for action potential?

    Approximately -65 mV.

    What occurs during spatial summation?

    Multiple signals arrive at different locations simultaneously.

    What is the consequence of EPSP and IPSP summation?

    Determines whether an action potential is generated.

    What is the significance of the cranial nerves in the autonomic nervous system?

    They emerge from the brain and control various autonomic functions.

    What happens during vasovagal syncope?

    Sudden stress leads to a drop in heart rate and fainting.
