Summary NSCA book
Chapter 1 - Structure and Function of the Muscular, Nervous,
and Skeletal Systems
Learning goals:
- Describe the structure and function of skeletal muscle.
- List and explain the steps in the sliding filament theory of muscle action.
- Explain the concept of muscle fibre types and how it applies to exercise performance.
- Describe the structure and function of the nervous system as it applies to the control
of skeletal muscle.
- Explain the role of exercise in bone health, as well as the function of tendons and
ligaments in physical activity.
3 types of muscle: smooth, cardiac and skeletal.
Skeletal muscle sticks to the bones and makes joints able to rotate, this type of muscle
makes us able to for example jump and throw things.
Each skeletal muscle is surrounded by connective tissue (epimysium). A muscle is further
divided by bundles of muscle fibres. These bundles are called fascicle.
Each fascicle is surrounded by connective tissue called perimysium.
Within a fascicle, each muscle fiber is surrounded and separated from adjacent fibers by a
layer of connective tissue referred to as endomysium.
A muscle fiber contracts and generates force.
The sarcomere is the basic contractile unit of muscle.
These include mitochondria (singular is mitochondrion), which are the sites of aerobic ATP
production within the cell and thus of great importance for aerobic exercise performance.
, In summary, myosin is a motor protein most notably involved in muscle contraction. Actin is
a spherical protein that forms filaments, which are involved in muscle contraction and other
important cellular processes. Tropomyosin is a long strand that loops around the actin
chains in the thin filament.
