Where is calcium stored inside a sarcomere?
T-Tubules
Sacroplasmic-Transverse Tubule Complex
Sarcoplasmic Reticulum
H-zones
This is the result of an decrease of negative charge within the cell; thus, making it more positive.
Depolarization
Hyperpolarization
Resting membrane potential
Repolarization
This is the result of an increase of negative charge within the cell; thus, making it more negative than usual.
Depolarization
Hyperplasia
Hypertrophy
Hyperpolarization
The following causes the relaxation of muscles, except:
Attachment of ATP
Decrease in Ca2+ ion concentration
Increase in Acetylcholinesterase
Formation of ADP
Refers to as slowchannels:
Voltage-gated Na+ channels
Voltage-gated K+ channels
Voltage-gated Ca2+ channels
Na+ co-transport with glucose and amino acids
