A skinny, 22 year-old male fat visits the local medical clinic complaining of severe cramping in his calves,
thighs, buttocks, back, and shoulders
- muscle loss.
- cramping pain

anatomy of muscle
skeletal muscle
- Skeletal muscles contribute to the maintenance of homeostasis in the body by generating heat.
- Muscle contraction requires energy, and when ATP is broken down, heat is produced.
- Each skeletal muscle is an organ that consists of various integrated tissues. These tissues include the skeletal muscle fibers, blood vessels, nerve fibers, and connective tissue.
the layers of the muscle
- Each skeletal muscle has three layers of connective tissue (called “mysia”) that enclose it and provide structure to the muscle as a whole, and also compartmentalize the muscle fibers within the muscle
-
skeletal muscle fiber
Sarcolemma
- membrane surrounding the muscle fiber.
T tubules
- the parts of sarcolemma that fold into the muscle fibers&allow membrane potential to reach all myofibrils inside the cell.
-
sarcoplasmic reticulum
- the smooth endoplasmic reticulum that stores calcium in a resting muscle cell.
actin
thin filament are primarily composed of two stands of actin protein twisted around each other to form a helical shape.
myosin
interact with other myosin proteins, forming thick filaments.
tropomyosin
- protein that is involved in muscle contraction, works together with troponin is thin filament.
troponin
- the regulatory protein, interact with ion calcium. when calcium is released, both regulatory proteins change shape & allowing actin.

-
-
losing muscle mass
cause metabolism to drop, because muscle burns more calories than fat
become susceptible to bone loss and immune capacity is decreased,
-
drinking too much water
may lead to depletion of potassium, which is an essential nutrient.
cause symptoms like leg pain, irritation, chest
-
drinking too much water
affect the kidney , and it will be harder for the kidney to filter these amount of water.
