kozerog [31]

Answer:

Sympathetic nervous system

Explanation:

Under stress conditions, the sympathetic division of the autonomic nervous system prepares the body by exhibiting flight or fight response. It includes some physiological changes in the body during stress conditions such as before and during exams.

Some of the physiological responses of the sympathetic nervous system are rapidly pounding, dilated pupils of eyes, deep breathing, dry mouth, and sweaty skin. It also shunts the blood circulation towards active skeletal and cardiac muscles. Dilation of bronchioles to increase ventilation to facilitate the delivery of more oxygen to the body cell is another change stimulated by the sympathetic nervous system. Therefore, the mentioned responses are due to the activation of the sympathetic nervous system of the student since he is in the stress of the exam.

The rate of firing of the postsynaptic neuron depends on the amount of ______ input it receives from the presynaptic neuron.
AysviL [449]

The postsynaptic potential is the membrane potential, which takes place in the neuron present post synapsis (after the chemical synapse). The presynaptic neuron releases neurotransmitter, which causes the firing in the postsynaptic neurons.  

The firing of the post synaptic neuron depends on the excitation and inhibition inputs received from the presynaptic neuron. The firing is the resultant of the summation of excitatory and inhibitory potential. In case, the excitatory potential is greater than inhibitory potential, the post synaptic neuron would be excited. in case, inhibitory potential is greater than excitatory potential, then the post synaptic neuron would be inhibited.  


Hence, the correct answer is option d.
