How Does Contraction Begin?

How Does Contraction Begin?. Nerve impulse reaches an axon terminal & synaptic vesicles release acetylcholine (ACh) ACh diffuses to receptors on the sarcolemma & Na+ channels open and Na+ rushes into the cell A muscle action potential spreads over sarcolemma and down into the transverse tubules

NEUROMUSCULAR BLOCKING AGENTS AND MUSCLE RELAXANTS Drugs that effect skeletal muscle function:

NEUROMUSCULAR BLOCKING AGENTS AND MUSCLE RELAXANTS Drugs that effect skeletal muscle function: 1. Neuromuscular blockers - used surgical procedures to cause muscle paralysis 2. Centrally acting muscle relaxants - reduce spasticity in neurologic conditions NEUROMUSCULAR BLOCKING DRUGS
