A muscle contraction is called isometric, when
Only the tension is changed but not the length of the muscle
Only the length of the muscle is changed not the tension
Muscle shortens and in the same time tension is also
None of the above
Which ion channel forms the voltage sensor part of the triad?
L type (DHP sensitive) calcium channel
Na+/Ca2+ antiporter
T type (ryanodin sensitive) calcium channel
ATP dependent Ca2+ "in" pump
Electro-mechanical coupling is
The calcium release resulting from the neurogenic action potential
The binding of actin and myosin
The shortening of a muscle fibre
The process which starts with the myogenic action potential and lasts until the end of contraction (followed by relaxation)
The following is characteristic of heat production in fast, glycolytic, white muscle fibres
Resting heat production is much larger than the initial heat production
Activation heat production is much larger than the initial heat production
After the shirt, initial glycolytic phase of heat production, a long-lasting oxidative phase begins, that produce just small amount of heat
Restitution hear production is much larger than the initial heat production
Which protein is not a component in the Troponin complex?
Troponin C
Troponin I
Troponin M
Troponin T
Characteristic to the myogenic response of single-unit muscels:
In case of stretching the mechano-sensitive cation-channels open up, creating depolarization
It requires specific innervation
It is under the direct coordination of central nervous system
It requires the cooperation of the endocrine system
What is the function of troponin-T?
Binds troponin complex to tropomyosin
Responsible for actin-myosin binding
Activates the alpha-actinin
Binds to the actin
The elementary contractile units of muscle fibres are
Fibrils
Myocytes
Sarcomers
Myofibrils
What are the mixed contraction forms?
Auxotonic contraction, preload, afterload
Twitch, tetanic contraction, cadaverous rigidity
Isotonic-, isometric contraction, tetanic contraction
Isometric contraction, twitch, cadaverous rigidity
At the end of muscle contraction
The myosin head is in its lowest energy status
The myosin head is energetically fully charged
The troponin-C releases ATP
Tropomyosin slides to the groove of actin
The gamma-efferent innervates
The intrafusal-fibre
The Golgi-receptor
The skeletal muscle
The subcutaneous metarterioles
