Nervous System - Recap

For this scenario, name the stimulus

• stepping on lego bricks

• foot

• walking barefoot on the floor

• pain

For this scenario, name the receptor involved

• chemoreceptor

• mechanoreceptor

• photoreceptor

• sensory neuron

For this scenario, the person jumped up in pain.

Name the effector

• foot/leg muscles

• hand muscles

• motor neuron

• negative feedback

Jumping up in pain in this scenario would be called a

• response

• effector

• stimulus response model

• reflex

A receptor in your body detects a stimulus, where does the impulse travel?

• Along a motor neuron

• Along an interneuron

• Along a sensory neuron

• Along the Myelin Sheath

You accidentally grab a hot pan and pull away without thinking about it

This is an example of a

• reflexion

• reaction

• response

• reflex arc

What is the difference between a reflex and a normal response?

• It is slower

• It is faster

• There is no difference

• A reflex doesn't have a stimulus

In a reflex arc, the impulse skips the brain and goes from a sensory neuron, to an interneuron and then a motor neuron

• True

• False

Which numbers correspond to the junction between two neurons?

• 1 & 2

• 2 & 3

• 3 & 4

• 1 & 5

Number four is pointing towards

• myelin sheath

• axon

• axon terminal

• nucleus
