Cross-bridge formation that results in muscle contraction requires intracellular?
the major intracellular ion in crossbridge formation is what
What is the process of excitation contraction coupling?
cross bridge formation "Excitation-contraction coupling" connects muscle fiber excitation to the muscle fiber contraction (cross bridge formation). During contraction, myosin heads form cross bridges many times-with each cross bridge generating a small amount of tension in the muscle fiber.
Fracture bridge occurs during what stage of bone healing?
Reparitive phase - 2nd phase of bone healing
1 Describe the ionic events underlying the nerve action potential 2. Describe the steps in cross bridge cycle that produces skeletal muscle contraction.?
thick filaments pulling thin filaments toward the center of the sarcomere
What i s latch bridge mechanism in smooth muscle?
smooth muscles have the ability to sustain the prolong contraction with a little use of energy.this latching of energy in smooth muscles is called latch phenomena,smooth muscles have ability to reduce strength of stimulus once they have fully contracted
What describes the events of contraction in excitation-contraction coupling?

What best describes the events of excitation in excitation-contraction coupling?
cross bridge formation "Excitation-contraction coupling" connects muscle fiber excitation to the muscle fiber contraction (cross bridge formation). During contraction, myosin heads form cross bridges many times-with each cross bridge generating a small amount of tension in the muscle fiber.
How would the loss of acetylcholinesterase from the motor end affect skeletal muscle?
Acetylcholine release is necessary for skeletal muscle contraction, because it serves as the first step in the process, enabling the subsequent cross-bridge formation. A muscle's ability to contract depends on the formation of cross-bridges between myosin & actin filaments. A drug that blocks acetylcholine release would interfere with this cross-bridge formation and prevent muscle contraction

What is molecular muscular contraction?
1. ATP hydrolysis 2. Cross-bridge formation 3. Release of ADP and phosphate (p) 4. ATP binding; Cross-bridge dissociation
How does blocking the activity of acetylcholinesterase affect skeletal muscle?
Acetylcholine release is necessary for skeletal muscle contraction, because it serves as the first step in the process, enabling the subsequent cross-bridge formation. A muscle's ability to contract depends on the formation of cross-bridges between myosin & actin filaments. A drug that blocks acetylcholine release would interfere with this cross-bridge formation and prevent muscle contraction
What is a speleothems formation in a cave?
it is a cave formation deposited by dripping or flowing water . it is NOT a natural bridge
Why are some bridges supported by rolles at one side?
Thermal expansion and contraction can put huge stresses into a large structure such as a bridge. To minimise this effect, the rollers are designed to allow the end of the bridge to move with the expansion and contraction.
One end of a steel bridge is not fixed to provide for expansion?
to allow for expansion and contraction
How do cross bridge power stroke bring about shortening of muscle contraction in human?
because it funny
Why are there joints in bridges?
The space at the joints is there to allow for expansion and contraction of the length of the bridge depending on the temperature.
