Biology; Chemistry; Physics: Post your doubts here!

Hmm. Every reflex action does. But the knee jerk does not.

How come?
Then how would the impulse go from the sensory to motor neuron?

 

[funky brat]

Relay is there as well. No??

No, see the book.

It crosses the sensory to motor across a synapse.

 

[Dark Destination]

It crosses the sensory to motor across a synapse.

Woah.

 

[funky brat]

Guys it's Biology ATP tomorrow.

Guys it's Biology ATP tomorrow.

Yes man *depressed*

 

[funky brat]

Woah.

Only the the withdrawal reflexes have relay neurones.

 

[funky brat]

Yes man *depressed*

You don't look like.

The notes that my teacher gave has the relay. The reflex arc has to pass the relay which associates the sensory and the motor. So, relay is there.

Investigation to find the change in dry mass of seeds during germination?

 

[Dark Destination]

What should we know about the topic of teeth? :/

 

[peacce]

You don't look like.

I m *sigh* :'(

 

[Mahnoorfatima]

Am I right or no? Funky brat? Dark Destination??

 

[funky brat]

What should we know about the topic of teeth? :/

What should we know about the topic of teeth? :/

Types of teeth, their functions, tooth decay etc.

 

[Fate0]

What should we know about the topic of teeth? :/

What the 4 types of teeth do and decay of teeth.

 

[***amd***]

Which neurones are involved in the Knee-jerk reflex and why? Anyone?

sensory, relay, motor neuroons.
isnt it just this?

 

[funky brat]

Am I right or no? Funky brat? Dark Destination??

Well, see the book.

 

[Fate0]

There is no relay neuron in knee jerk. It's a monosynaptic reflex meaning only one synpase, between the sensory and motor.

RELAY IS NOT THERE.

Exactly. (Y)
