definition - 🧠 ANSWER ✔✔Muscle physiology is the study of muscle
function.
3 major muscle types - 🧠 ANSWER ✔✔Cardiac, skeletal, and smooth
cardiac muscle - 🧠 ANSWER ✔✔Cardiac muscle is self-stimulating, in that
it works without conscious thought. Cardiac muscle surrounds the heart,
contracting with every beat. It has properties of skeletal muscle in that it will
improve in size, thickness and strength with training. The stronger the heart
muscle, the more blood containing oxygen and nutrients may be sent to the
body for energy. We will discuss the structure and function of the heart
during the period of instruction on the Oxygen Transport System or OTS.
Skeletal muscle - 🧠 ANSWER ✔✔Skeletal muscle is voluntary in that we
can control the stimulation to contract this type of muscle. Skeletal muscles
attach to bones and provide movement and stability. Most of our discussion

, about the muscular system in this course will pertain to training skeletal
muscle for improved physical performance.
Smooth muscle - 🧠 ANSWER ✔✔Smooth muscle is involuntary in its ability
to stimulate itself to contract. Smooth muscle is found in the lining of the
intestines and the vascular system. Smooth muscle works on its own,
without conscious thought. You don't have to think about digestion or blood
flow to make it happen. Smooth muscle contracts, providing movement of
food through the intestines and blood vessel expansion and constriction.
Muscle structure - 🧠 ANSWER ✔✔Tendons attach whole skeletal muscles
to bones. Whole skeletal muscles consists of bundles of fasciculi (bundles
of fibers). Each fiber (muscle cell) contains many sarcomeres. A sarcomere
is the smallest functional unit of muscle consisting of the myofiliments:
actin, myosin and troponin.
Connective tissue covers the outside of the entire muscle (epimysium),
bundles of muscle (perimysium) and myofibrils or fasciculi (endomysium)
that bundle the individual fibers.
