Algunas drogas bloquean los químicos secretados por los axones. ¿Cómo podrían afectar estas drogas al impulso nervioso? ¿Qué pod
olya-2409 [2.1K]

Answer:

Algunas drogas intervienen en el impulso nervioso inhibiendo la liberacion de  neurotransmisores, por ende estas neuronas no generaran efectos postsinapticos.

Podria pasar que algunos procesos internos estaran inhibidos o fomentando indirectamente la aparicion de otros, un ejemplo claro de esto es la xerestomia generada por las drogas betabloqueantes.

Explanation:

Es asi que los procesos internos se veran desregularizados, las drogas que inhiben la liberacion de los neurotransmisores son reguladores por lo general de la tension arterial o antiarritmicos cardiacos, es por eso que su consumo es fundamental y vale el riesgo beneficio a la hora de evaluar la inhibicion de las respuestas postsinapticas.

Los neurotransmisores mas conocidos son la noradrenalina y adrenalia, le membrana presinaptica es la nerviosa y la postsinaptica puede ser muscularo o nerviosa.

The force of attraction between a divalent cation and a divalent anion is 1.64 x 10-8 N. If the ionic radius of the cation is 0.
Elden [556K]

The radius of the anion is 7.413 nm

<h3>How to calculate the force of attraction between charges</h3>

The force of attraction (F) is given by the formula:

  • F = (1/4π∈r²)(Zc*e)(Za*e)

where:

∈ = permittivity of free space = 8.85*10⁻¹⁵ F/m

Zc = charge on the cation = +2

Zc = charge on the anion = -2

e = charge on an electron = 1.602 * 10⁻¹⁹ C

r = interionic distance

r = rc + ra

where rc and ra are the radius of the cation and anion respectively

F = 1.64 * 10⁻⁸ N

Therefore based on the equation of force of attraction:

1.64 *10⁻⁸ = [1/4π(8.85*10⁻¹⁵)r²](2 * 1.602*10⁻¹⁹)²

r² = 5.63 * 10⁻¹⁷

r = 7.50 nm

Since r = rc + ra

where rc = 0.087 nm

thus, ra = r - rc = 7.50 - 0.087

ra = 7.413 nm

Therefore, the radius of the anion is 7.413 nm
