10 Questions
What is the molecular mechanism responsible for muscle contraction?
Binding of troponin-C to actin
What initiates the attractive force between actin and myosin crossbridges during muscle contraction?
Movement of calcium ions into the nerve terminal
What represents the relaxing proteins that inhibit interaction between actin and myosin?
Tropomyosin
What leads to muscle fatigue during prolonged and strong contraction?
Depletion of muscle glycogen
What is the main result of forceful muscular activity on a muscle?
Muscle hypertrophy
What is the function of the T-tubules in muscle physiology?
They help for rapid transmission of action potential
What covers the active sites on actin molecules in myofibrils during resting state?
Tropomyosin
What is the main composition of the sarcoplasmic reticulum in muscle physiology?
Longitudinal tubules and terminal cisterns
What is the function of the postsynaptic density in the nervous system?
Contain neurotransmitter receptors
What is the structure that is innervated by only one nerve ending in muscle physiology?
Each muscle fiber
This quiz covers the overview of the nervous system, including the synaptic cleft, neurotransmitter receptors, and postsynaptic density. It also delves into muscle physiology, discussing muscle fibers, their cellular structure, and surrounding cell membrane.
