Development and adaptability of microvasculature in skeletal muscle.
In skeletal muscle, the size of the capillary bed is adapted to the type of muscle metabolism and can be altered by adaptation to different environments or increased activity. Muscle fibres with high aerobic metabolism have more capillaries, and an increase in aerobic metabolism is usually followed by capillary growth. It is assumed that local hypoxia - created by increased demand for oxygen du...
متن کاملHighly Aligned Skeletal Muscle Fibers
We propose highly aligned skeletal muscle fibers (Fig.1). We found that the textiles of a fibrin hydrogel fiber are highly orientated to the the longitudinal direction of the fiber by using a micro fluidic channel of a micro glass capillary tube. We also confirmed that the seeded skeletal muscle cells, C2C12, migrated into the fiber and aligned to the fiber direction without any complex lithogr...
متن کاملHighly extensible skeletal muscle in snakes.
Many snakes swallow large prey whole, and this process requires large displacements of the unfused tips of the mandibles and passive stretching of the soft tissues connecting them. Under these conditions, the intermandibular muscles are highly stretched but subsequently recover normal function. In the highly stretched condition we observed in snakes, sarcomere length (SL) increased 210% its res...
متن کاملThe Dynamic Properties of Mammalian Skeletal Muscle
The dynamic characteristics of the rat gracilis anticus muscle at 17.5 degrees C have been determined by isotonic and isometric loading. For a fixed initial length these characteristics were represented either as a family of length-velocity phase trajectories at various isotonic afterloads or as a series of force-velocity curves at different lengths. An alternate method of viewing these data, t...
متن کاملGastrocnemius Skeletal Muscle Microvasculature and Neuromuscular Junction Alterations in Mice with Experimental Acute Chagas Infection
A light and transmission electron microscopy study was performed in skeletal muscles (SM) Gastrocnemius (G) from mice experimentally infected with Trypanosoma cruzi to determine changes on microvessels (MV) and neuromuscular junction (NMJ) of G. In this study 10 male (mus musculus) (20 g) were infected subcutaneally with 1.10 bloodstream trypomastigotes M/DID/Ve/02/DSM strain. Five mice were ke...
