See how sound, touch, and light affect action potentials of sensory neurons.
Science
Subthreshold, Threshold and Suprathreshold Stimuli
How the stimulus intensity plays a role in generating action potentials.
Electrical Refractory (Recovery) Period following an Action Potential
Learn about the recovery time in between each action potential and how that affects things like heart rate.
What is an Action Potential? (Nerve Impulse)
We go over the events that make up an action potential in detail.
What is Hyperkalemia?
The causes, effects and treatment of hyperkalemia.
What is Hypokalemia?
The effects, causes and treatment of hypokalemia.
The Resting Membrane Potential
We go over basic electrical concepts and then dive into the physiological basis of this resting cell membrane potential (voltage of a cell in a steady state).
Cerebrospinal Fluid (CSF)
Formation, Circulation/Flow of CSF, and the clinical considerations in regards to CSF.
Neurons in the Nervous System
Structure of a nerve, general types of neurons, and functional categories of them.
Review of the Nervous System
We go over what makes up the CNS, the PNS, the meninges, dermatomes and the supporting cells of the CNS and PNS.
