b) infinite,longest length
c) zero, shortest length
d) infinite , shortest length

Answer:Keywords: muscle contraction, lattice spacing, length–tension curve, spatially explicit, ... An increase in lattice spacing implies that the unstrained location of a myosin head ... To isolate the effects of filament overlap on isometric maximum force, the ... change seen at shorter sarcomere lengths under isovolumetric conditions.
Muscle contraction usually stops when signaling from the motor neuron ends, which ... A myofibril is composed of many sarcomeres running along its length; thus, ... The sliding can only occur when myosin-binding sites on the actin filaments are ... But each head can only pull a very short distance before it has reached its ...
Explanation:
Answer:
C, zero, shortest length
Explanation:
When the Z-discs of the sarcomere abut the myosin filament, the myosin ends are crumpled and the force of contraction decreases rapidly, approaching zero.
