Explain the Length-tension property of a muscle contraction.

Angular work is positive during eccentric muscle contraction and negative during concentric muscle contraction. With the...

Angular work is positive during eccentric muscle contraction and negative during concentric muscle contraction. With the aid of sketches, explain the reason for work to be positive and negative for eccentric and concentric muscle actions, respectively.

Identify the components in a muscle unit and explain how they are recruited during a contraction and how muscle tension and fatigue are generated in skeletal muscle.

During the excitation phase of the skeletal muscle cell contraction, the following occurs: 1) the muscle fiber develops tension and shortens 2) the muscle fiber relaxes and returns to its original length 3) nerve action potentials lead to muscle action potentials A growing long bone in a child has only two types of cartilage at the epiphysis. These two areas are 1) elastic cartilage and epiphyseal plate 2) epiphyseal plate and epiphyseal line 3) primary and secondary ossification centers 4)...

Explain how the following agents are involved in the excitation and contraction of skeletal muscle. i. Acetylcholine (ACh) ii. Calcium (Ca2+) iii. Adenosine triphosphate (ATP)

A muscle is undergoing a contraction at a length corresponding to 1.3 L0. If you assume that the contraction is isometric, what is the relative force the muscle is likely to be producing? If the muscle is actually producing 0.65 F0, predict whether the muscle is actually isometric or whether it is shortening or lengthening. In order to gain full credit, you need to show your work, including a listing of (1) the governing equations, (2) all parameters and variables,...

1) Write in order the sequence of events that occurs during muscle contraction. Begin in the brain and include all action in the muscle. You can write it out like a flow chart, one action followed by the next. 2.The function of the T tubules is to _________. A) Store Ca2+ inside the muscle fiber. B) Rapidly conduct action potentials to the interior of the muscle fiber. C) To store neurotransmitter D) Conduct ATP molecules out of the mitochondria throughout...

How does an electrical impulse from a nerve lead to muscle contraction? How does skeletal muscle contract and generate force? How does muscle twitch, summation, and tetanus affect the strength and duration of muscle contraction? What are the different types of skeletal muscle contractions? Explain the difference? Own Words Please.

1. How is the contraction of a skeletal muscle cell different than the contraction of a smooth muscle cell? How does this aid in each muscle cell's function? 2. What is the purpose of myoglobin in slow-twitch muscle fibers? Why is there more myoglobin in slow-twitch muscle fibers than in fast-twitch fibers? 3. What is the purpose of gap junctions in cardiac muscle cells and some smooth muscle cells?
