neuromuscular disorders

Question 1

what are motor end plates

Answer 1

the synapses formed between motor neurons and muscles

Question 2

how does information pass along the neuromuscular junction

Answer 2

-Action potential moves along the nerve
-Voltage gated calcium channels open allowing influx of calcium
-Vesicles of acetyl choline released into synaptic cleftAcetyl choline diffuses across the synaptic cleft
-The acetlcholine receptor opens and renders the membrane permeable to Na / K ions
-The depolarisation starts an action potential at the motor end plate
