This type of muscle fiber shows up darkest under a microscope.
Type 1
Hypertrophy is cased by increases in these components of a muscle.
Increase in: Actin, Myosin, Sarcoplasm, Connective Tissue, Myofibrils
This is how much ATP is produced from 1 molecule of glycogen.

This portion of the brain regulates homeostasis
Hypothalamus
This zone of a sarcomere contains both actin and myosin.
A-Band
This fiber type is most effected by a cession of training. (DAILY DOUBLE)
Type 1
This pathway converts lactate back into glucose in the liver.
Cori Cycle
These 4 metabolic byproduct can result in fatigue.
H+ accumulation, Heat, Lactic Acid, Phosphate
This nerve regulate muscle length and tone
Gamma motor neuron
These are the 3 compounds on a myosin head in a resting state.
ADP, Phosphate, ATPase
Resistance training stimulates this molecule which results in an increase in mTOR.
IGF-1
