Explanation / Answer

An excitatory postsynaptic potential (EPSP) is the change in membrane voltage of a postsynaptic cell following the influx of positively charged ions into a cell (typically Na+) as a result of the activation of ligand-senstive channels.
From the given option d is correct that is none of the above is responsible for EPSP.
Spinal menengis do not provide physical support to the spinal cord infact they protect it from any kind of shock. Therefore option A is correct.
3. Option B is correct. Somatic motor neuron cell bodies are located in the anterior gray horn of the spinal cord and leave the spinal cord and leve the central nervous system via the ventral root.
4.Polysynaptic reflexed habe one or more interneurons connecting afferent and efferent signals Option A is correct.
5. Somatic motor commands are intiated in the primary motor cortex.
6.Muscarinic Cholinergic Nicotinic Cholinergic both are direct acting receptors
7. Basal ganglia and cerebellum responsible for modulating movement which has been initiated by the priamary motor cortex.
8. Glutamate is the peptidal neurotransmitter.
