What is a reflex arc?
a neural pathway that requires conscious thought to react to a stimulus
a neural pathway that causes an involuntary and immediate reaction to a stimulus
a neural pathway that is always controlled by the brain
a neural pathway that requires learning to develop
|
What triggers a reflex arc?
a relay neurone
a stimulus
a motor neurone
an effector
|
What detects the stimulus that triggers a reflex arc?
receptors
effectors
motor neurones
sensory neurones
|
What transmits the impulse from the receptors to the spinal cord or brain?
motor neurones
sensory neurones
effectors
relay neurones
|
What transfers the impulse from the spinal cord or brain to the effector?
receptor
sensory neurone
motor neurone
relay neurone
|
Which type of neurone connects sensory neurones to motor neurones in a reflex arc?
relay neurone
motor neurone
effector neurone
sensory neurone
|
What is the role of the effector in a reflex arc?
to detect the stimulus
to receive the signal and carry out the response
to connect sensory neurones to motor neurones
to transmit the impulse to the spinal cord
|
Describe the main stages of a reflex arc that involves the spinal cord.
|
What is a key feature of reflex arcs?
they require learning to develop
they always involve the brain in the decision-making process
they are involuntary
they are slow to respond
|
Give 2 key features of reflex arcs.
