Skeletal Muscle Microanatomy
Fascicles, fibers, myofibrils, sarcomeres. How a whole muscle is built from the inside out.
Motor Units and Muscle Mechanics
What a motor unit is and how muscles grade their force.
Four pre-work days. Five topics. How muscles actually contract at the molecular level, and how neurons actually generate and send signals. Each topic page walks you through the reading, the fill-in-the-blank notes, the video, and then opens your nightly spaced-recall cards. Open one topic on Mon, Tue, Thu, Fri. Wednesday is catch-up and discussion.
Same four steps every pre-work day. The order matters. The retrieval check is what makes the cards work.
Pick the day's topic from the list below. Print that day's lab workbook before you sit down. Breaking flow to find a printer is where good study sessions die.
Finishing the video is what starts the retrieval gate. Read the fill-in-the-blank notes alongside it.
Pull together what the video just taught you. Submitting unlocks the spaced-recall cards for the topic.
DOK 1 to DOK 3 cards. They carry over into future Daily Reviews so the work compounds.

Each topic links to its lecture page. The lecture page is the gate into your spaced-recall cards for that topic.
Skeletal Muscle Microanatomy
Fascicles, fibers, myofibrils, sarcomeres. How a whole muscle is built from the inside out.
Motor Units and Muscle Mechanics
What a motor unit is and how muscles grade their force.
Sliding Filament and the Cross-Bridge Cycle
How actin and myosin actually contract. The molecular event behind every muscle move.
Neurons and Resting Membrane Potential
Neuron parts plus the ion balance that creates the -70 mV resting state.
Action Potentials and Synaptic Transmission
Depolarization, repolarization, and how one neuron talks to the next.
Each pre-work day takes about 30 to 45 minutes if you sit with it. The retrieval check is the part that makes it stick. Do not skip writing those 60 words, even when the cards look like the easier path.
If you fall behind on a day, do that day's topic first before moving to the next. The spaced-recall cards only schedule properly when you have done the work on the topic page first.

Microanatomy and motor units together. Both feed directly into Tuesday's sliding filament story.
