Cutaneous Perception

Lateral inhibition

Myotatic Reflex

Referred pain

Vision

• Types:
  • Myopia
  • Hyperopia
  • Color blindness
• How do we fix them?

Stimulus coding

Lab Purpose

To allow students to experiment with principles of skeletal muscle function, metabolism and anatomy.

Lab objectives

• Explain each of the steps involved in a muscle contraction.
• Describe the parts and movement of a sarcomere.
• Explain how training changes muscle strength.
• Define fatigue and explain how fatigue occurs during different muscle activities (e.g. weight lifting vs. 200 yard sprint vs. marathon run).

Lab Safety

• This is a reasonably safe lab, just be careful with the equipment.

Experiments

1. Muscle Contraction
2. Muscle Strength
3. Muscle Fatigue

Muscle Contraction Demo

• Done with the tens unit and gating board.
• I'll walk each group through it.
