BIO 304 · Week 4 of 8 · Jun 29 to Jul 5 · Nightly Pre-Work

How muscles contract, how neurons fire.

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.

How each pre-work session runs

Four steps, in order.

Same four steps every pre-work day. The order matters. The retrieval check is what makes the cards work.

01

Open the topic, print the workbook

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.

02

Watch the short video

Finishing the video is what starts the retrieval gate. Read the fill-in-the-blank notes alongside it.

03

Write the 60-word check

Pull together what the video just taught you. Submitting unlocks the spaced-recall cards for the topic.

04

Run the nightly cards

DOK 1 to DOK 3 cards. They carry over into future Daily Reviews so the work compounds.

Your four pre-work days

Open one topic per day.

Each topic links to its lecture page. The lecture page is the gate into your spaced-recall cards for that topic.

MON 29
Day 13 . Pre-work

Skeletal Muscle Microanatomy

Fascicles, fibers, myofibrils, sarcomeres. How a whole muscle is built from the inside out.

Open topic Submit lab

Motor Units and Muscle Mechanics

What a motor unit is and how muscles grade their force.

Open topic Submit lab
TUE 30
Day 14 . Pre-work

Sliding Filament and the Cross-Bridge Cycle

A note from me

Week 4, same rhythm.

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.

Day 13 is two topics. Open it.

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