Suponga que existen tres neuronas presinápticas, A, B y C, que establecen sinapsis contiguas en la misma neurona postsináptica D. No se inicia ningún impulso nervioso en la neurona postsináptica como resultado de impulsos nerviosos individuales en A, B o C, ni tampoco si los impulsos llegan simultáneamente a las tres, a A y B o a A y C. Solamente si llegan juntas los impulsos a las sinapsis de B y C, D disparará un impulso. Explique estos resultados en términos de los neurotransmisores excitadores e inhibidores y de sus efectos en el potencial S de membrana de la célula postsináptica . Ayuda que no entendi nada...

Bis the correct answer.

If these are the missing choices: a. to determine skin temperature, place the back of your hand against the patient's skin.b. determine body temperature by touching the patient's hands and feet.c. skin temperature will tell you very little about this patient's condition or well-being.d. the patient's skin temperature and color will likely be warm and red.my answer is: a. to determine skin temperature, place the back of your hand against the patient's skin. using the back of the hand to check for temperature rather than the palm is more effective because the back of the hand has more nerves that can feel and transmit the temperature than the palm.
