Answer #1

because of titin muscle are elastic, skeletal muscle are attached to bone via tendon under a constant level of stretch called resting length

muscle fibers do not produce the same amount of isometric force when they are activated at different static lengths.

during contraction, muscle exist in state that optimise force by interlacing myofilament cause sarcomere shortening and decrease in force

instretch,insufficient myofibril is there so less force is produced

tension generated in skeletal muscle is a function of the magnitude of overlap between actin and myosin myofilaments.

What happens if the angle of incidence (from inside the material) is greater than the critical angle of refraction found in part (a) above? Why? This is called total internal reflection. Why is it only possible to have total internal reflection when light travels from a medium of higher index of refraction to one of lower index of refraction?

Certain types of snake venom contain α-bungarotoxin, which is a competitive antagonist for nAChR. What happens to the response of the postsynaptic skeletal muscle cell when the venom is present? What would this cause to happen to a person bitten by the snake? What other toxin discussed in the textbook would cause a similar result to the patient by altering the release of ACh rather than interacting with the nAChR itself?
