Anatomy and physiology What visible features of the neuromuscular junction (NMJ) muscle tissue indicate that it is skeletal muscle?
The disease poliomyelitis (po′le-o-mi′˘e-li′tis) destroys motor neurons, causingloss of muscle function and even flaccid paralysis. Some patients recoverbecause axon branches form from the remaining motor neurons. Thesebranches innervate the paralyzed muscle fibers to produce motor unitswith many more muscle fibers than usual. How does this reinnervation ofmuscle fibers affect the degree of muscle control in a person who hasrecovered from poliomyelitis?
The next time you sit down to a turkey dinner, you may beasked if you prefer the “white meat” or the “dark meat.” Whatcan you say about the diameter of the muscle fibers of eachtype of meat? Which would be fast glycolytic fibers and whichwould be slow oxidative fibers? In life, which type of musclewould have had the greatest resistance to fatigue?
It is not an easy matter to assign particular func-tions to specific components of the basal lamina, sincethe overall structure is a complicated composite materialwith both mechanical and signaling properties. Nidogen,for example, cross-links two central components of thebasal lamina by binding to the laminin γ-1 chain and totype IV collagen. Given such a key role, it was surprisingthat mice with a homozygous knockout of the gene fornidogen-1 were entirely healthy, with no abnormal phe-notype. Similarly, mice homozygous for a knockout of thegene for nidogen-2 also appeared completely normal. Bycontrast, mice that were homozygous for a defined muta-tion in the gene for laminin γ-1, which eliminated just thebinding site for nidogen, died at birth with severe defectsin lung and kidney formation. The mutant portion of thelaminin γ-1 chain is thought to have no other functionthan to bind nidogen, and does not affect laminin struc-ture or its ability to assemble into the basal lamina.…
