Question

State 8 effects that would happen when a sensory neuron recieves a stimulus that brings it to threshold.

Answer 1

Any stimulus is a form of energy, so when some energy applied in the form of stimuli, this causes change in membrane potentials (enough to reach threshold potentail difference) of neurons innervating that region, and causes depolarisation, which results in impulse generation and transmission.

Depend upon the severity of stimuli, the duration of impulse varies. These senses are received by sensory receptors. These receptors transduce the stimuli and send signals to the CNS. All the sensory pathways involves four basic functions namely, sensory reception and transduction, transmission, perception, amplification.
