A student postulated that the sodium pump directly causes action potentials along neurons. Is this hypothesis reasonable?
Leviafan [203]

Answer:

No.this does not cause action potential.

Explanation:

Action potential is formed from the  influx of sodium ions through the special  sodiun channels call  volatage gated channels.

The influx caused deoplarisation and if upto to  the threshold level give action potential.

The  influx of sodium and out flux at the  node of  Ranvier does not lead to action potential neither does  hydrolysis of ATPs  for its active transports process.

The sodium pump is for maintenance of  electrochemical gradients with potassium for maintaining Resting Membrane Potential of the neuron.

Cheranita is experiencing the first stage of the general adaptation syndrome. an environmental stressor has triggered a process
aniked [119]
The correct answer is hypothalamus; autonomic.
The General Adaptation Syndrome (GAS) is the sequence of physiological processes which occur when we are exposed to a stressor. GAS is comprised of three stages which are the alarm, the resistance, and the exhaustion phase.

The first stage, known as the alarm phase, involves the fight or flight response, which is the natural reaction when under threat. A distress signal is sent by the amygdala to the hypothalamus, which in turn activates the sympathetic branch of the autonomous nervous system.
