1. Functions of the Muscular System
2. Sliding Filament Theory- Understand the basic steps described in class and be able to explain how the
nervous system, Calcium, ATP/ADP, myosin heads, actin, power stroke, etc all contribute to a muscle
contraction.
3. Muscle Fatigue
4. Clinical Applications of Muscular System- Be prepared to answer questions regarding each topic.
Specific information was presented on Thursday and can be located on class resource page.
 Muscular Atrophy & Muscular Hypertrophy p 279
 Exercise Induced Muscle Damage p 279
 Rigor Mortis p 285
 Pharmacology of the NMJ p 286
 Creatine Supplementation p 290
 Aerobic Training vs Strength Training p 293
 Anabolic Steroids p 297
5. Structure of the Muscle-how is it arranged?
6. Identification-You will be responsible for the knowing location and function of all the muscles we
noted/starred on the coloring page.(Frontal, Orbicularis Oculi, Orbicularis Oris, Masseter, Temporal,
Sternocleidomastoid, Trapezius, Pectoralis Major, Latissus Dorsi, Deltoid, Biceps Brachii, Triceps Brachii,
External Obliques, Rectus Abdominus, Sartorius, Gluteus Maximus, Quadriceps Group, Hamstring Group,
gastrocnemius, )
7. Three Types of Muscle- How they look, where they’re located, whether they are voluntary or involuntary.
Be able to identify them based on their visual appearance.
8. Muscular Diseases/Disorders-Muscular Dystrophy, Fibromyalgia, Cerebral Palsy, Distonia and Spinal
Muscle Atrophy. Review Muscular System Intro Packet and notes from Monday’s video.
9. Understand how muscles can only contract and relax and they work in pairs to create smooth movement.
10. Review all Analysis & Review Questions from the Stations Lab
