Nerve Impulse Sequence

Which type of neuron transmits a signal from the central nervous system to an effector such as a muscle?

• sensory

• motor

• relay

• dendrite

The gaps between neurons are called

• Effectors

• neurotransmitters

• reflexes

• synapses

What happens at Y?

• The brain interprets nerve impulses and the image appears upright.

• The brain interprets nerve impulses and the image appears inverted.

• The brain carries out response.

Which list describes the correct sequence of a simple reflex arc?

• A receptor, relay neurone, motor neurone, sensory neurone, effector

• B receptor, relay neurone, sensory neurone, motor neurone, effector

• C receptor, sensory neurone, motor neurone, relay neurone, effector

• D receptor, sensory neurone, relay neurone, motor neurone, effector

To produce a reflex action, the nerve impulses follows a pathway for this purpose is called….

• reflex arc

• reflex action

• flight response

• autonomic response

What is the chemical used by a neuron to transmit an impulse across a synapse to another nerve cell?

• Neurotransmitters

• Synapse

• Threshold

• Impulse

What is the generalised order during a nervous response?

• Receptor → stimulus → neurones → effector → response

• Response → receptor →neurones → effector → stimulus

• Stimulus → receptor → neurones → effector → response

• Stimulus → effector → neurones→ receptor → response

What is the correct sequence of events in the transmission of a nerve impulse?

• Resting potential, depolarization, repolarization, hyperpolarization

• Depolarization, resting potential, repolarization, hyperpolarization

• Repolarization, depolarization, resting potential, hyperpolarization

• Hyperpolarization, depolarization, repolarization, resting potential

Which part of the neuron receives incoming signals during a nerve impulse?

• Axon

• Dendrite

• Myelin sheath

• Node of Ranvier

What role does the myelin sheath play in nerve impulse transmission?

• It speeds up the transmission of nerve impulses

• It slows down the transmission of nerve impulses

• It generates nerve impulses

• It blocks nerve impulses
