Skeletal Muscles Flashcards
(18 cards)
What is a Sarcomere
The functional unit of muscle
What is Actins and its function
Thin filament; Anchors to the Z-line
What is Myosin and its function
Thick filament; Entire A-band
What is Tropmyosins function
A protine near the Z and A band; Covers the attachment site
what is Calcium Ions function
Removes protine from the band creating a contraction
What is the meaning of a Isometric contraction
The length of the muscle stays the same but the tension changes
What is the meaning of a Isotonic contraction
The Tension of the muscle stays the same but the length changes
What is the meaning of a Concentric contraction
Tension with muscle length decreasing
What is the meaning of a Eccentric contraction
Tension with muscle length increasing
What are proprioceptors
Cells in the muscles that aid the bodies position in space
What are Muscle spindles and there function
Detects streching
What are golgi tendons and there function
Detects Tension
What is the prime mover/agonist function
Muscles that is primarily performing the action
What is the synergists function
Muscles that assists the agonist/prime mover
What is the Antagonists function
Muscles that performs the opposite of the Agonist/Prime mover
What is the Fixators function
Muscles that stabilizes the movement
What is Aerobic metabolism
Mitocondria uses oxygen to create Adenosine Triphosphate (ATP)
What is Anaerobic metabolism
Mitocondria uses Glucose to create Adenosine Triphosphate (ATP); Produces lactic acid
