In order for an impulse to cross the synaptic gap between
the neurons, the impulse must be converted into a chemical signal as this will
allow it to exert effects and to be able to travel in distances such as having
to cross the synaptic gap between the neurons.
In the glomerulus, a tuft of capillaries in the renal cortex, blood is filtered through the porous capillary walls.
<span><span>
The glomerulus receives its blood supply (that need to be filtered) from an afferent arteriole of the renal arterial circulation and the glomerular capillaries exit into efferent arterioles. The glomerular filtration rate is a rate at which blood is filtered through all of the glomeruli.</span> </span>
I don’t know how to explain it but this might help
Answer:
d. more permeable to sodium ions.
Explanation:
The binding of Acetylcholine with the receptors at motor end plate facilitate membrane permeability to sodium ions therefore opening of voltage gated channels for sodium ions.
Sodium ions diffused into the synapse of post synaptic neuron at the neuromuscular junction.
If the stimulus is up to threshold levels; more chemical(neurotransmitter) gated sodium channels opens, and sodium ions move into the synapse to depolarize the membrane with reversal of charges to generate action potential.
The continuous binding of Acetycholine , leads to permanent opening of sodium ions,and over excitation from depolarization. Acetycholinesterase enzymes breakdown Acetycholine to choline and Acetyl Co -A. These are recycle back to Acetycholiine
