Unit 5
Muscle tissue, naming, and the muscles of the head and upper body
- Fiber LabTell skeletal, cardiac, and smooth muscle apart under the microscope, then build a skeletal muscle from the inside out, one connective tissue layer at a time.Play
- Muscle Name LabDecode muscle names, sort fascicle arrangements, cast muscle roles, and build the abdominal wall.Play
- Face WorkshopContract the muscles of the face and jaw to make expressions and move the mandible, and learn each muscle by what it does.Play
- Pull Lines: Upper BodyHang muscles on the skeleton, predict what they do, then contract them and watch the insertion swing toward the origin.Play
Unit 6
Contraction, the neuromuscular junction, breathing, and the lower limb
- Sarcomere BuilderZoom from a whole muscle down to its filaments, build a sarcomere piece by piece, and bracket its bands.Play
- Junction RunRide one acetylcholine molecule across the neuromuscular junction, learn every station on the way, then zoom out to see motor units.Play
- Breath MechanicRoute structures through the diaphragm, layer the intercostal muscles, and recruit the right muscles until the chest breathes.Play
- Pull Lines: Lower LimbHang the muscles of the hip, thigh, leg, and foot on the skeleton, predict what each one does, and watch the limb move.Play
