Question

Illustrate with the help of a word diagram the nervous pathway of the way you will open the door by hearing the door bell
​

Answer 1

Nervous Pathway of Opening the door upon hearing the ring of the bell :

• This nervous pathway is essentially a reflex arc , where we find a receptor, afferent neurons , CNS (brain and spinal cord), efferent neurons and effector.

So, let's start:

$\boxed{ \bold{ \: Bell \: rings \: at \: the \: door}} \\ .\: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \downarrow$

$\boxed{ \bold{ \: Sound \: is \: received \: at \: the \: ear}} \\ .\: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \downarrow$

$\boxed{ \bold{ \: The \: Auditory \: Nerve \: (8th Cranial Nerve) \: is \: stimulated}} \\ .\: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \downarrow$

$\boxed{ \bold{ \: Impulse \: is \: transmitted \: to \: brain \: via \: spinal \: cord}} \\ .\: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \downarrow$

$\boxed{ \bold{ \: The \: brain \: transmits \: effector \: impulse \: via \: spinal \: cord }} \\ .\: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \downarrow$

$\boxed{ \bold{ \: Spinal \: cord \: transmits \: that \: information \: to \: muscles \: of \: arms \: and \: legs }} \\ .\: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \downarrow$

$\boxed{\bold{\:Person\:walks\: towards\:door\:to\:op en\:it}}$

So, these series of events occur as a reflex arc.
