Which region controls heart rate, breathing rate and blood pressure without any conscious effort?

A student reads a word problem, decides on a method and writes the next line of working. Which part of the brain is doing most of this work?

Body temperature climbs above 37 degrees Celsius and sweating begins. Which region detects the change and triggers the response?

A gymnast holds a steady pose on a narrow beam and then lands a jump without wobbling. Which region is most responsible for that balance and smooth coordination?

Signals from the eyes are turned into an image the person is aware of seeing. Which lobe of the cerebrum does this?

Which structure joins the rest of the brain to the spinal cord and contains the medulla oblongata?

A person decides to raise one hand. In which part of the nervous system does that decision begin?

Which part of the nervous system is a bundle of neuron fibers that carries impulses out to the muscles of the leg?

Which part of the nervous system is protected by the vertebrae of the backbone?

Which part of the nervous system contains the cerebrum, the cerebellum and the medulla oblongata?

After an accident a patient can move every limb on command and feels touch normally, but staggers when walking and cannot bring a finger smoothly to a target. Which region was most likely damaged?

After an injury, a patient can no longer maintain a steady breathing rhythm or a stable heart rate, and needs a ventilator. Which region was damaged?

A patient's eyes and optic nerves test as healthy, but the patient reports seeing nothing after a blow to the back of the head. Which region was most likely damaged?

A patient speaks and moves both arms normally but has no movement and no feeling in either leg after an injury in the lower back. Which part of the nervous system was damaged?

After a deep cut to the wrist, two fingers on that hand have no feeling and cannot be moved. The rest of the body is normal. Which part of the nervous system was most likely damaged?

After a head injury a patient cannot hold on to new information or plan the coming day, though breathing, heart rate and reflexes are all normal. Which part of the nervous system was damaged?

In multiple sclerosis the fatty myelin sheath around many axons is broken down. What is the immediate effect on those neurons?

Which part of a neuron receives incoming signals from other neurons?

What is the job of the axon?

Which part of a neuron holds the nucleus and carries out the metabolism that keeps the cell alive?

Which type of neuron carries an impulse from the spinal cord out to a skeletal muscle?

A peripheral nerve is a bundle of many neuron fibers running side by side. Which part of those individual neurons makes up most of the bundle's length?

A receptor in the skin of the foot sends a signal that travels along a nerve to the spinal cord. Which type of neuron carries that signal?

Put these events in order: 1) the impulse travels along the axon; 2) the dendrites receive the signal; 3) neurotransmitter is released from the axon terminal; 4) the impulse passes through the cell body.

A tack pricks a finger. Put these events in order: 1) a motor neuron carries the command to the muscle; 2) a receptor detects the tack; 3) an interneuron in the spinal cord passes the signal on; 4) a sensory neuron carries the impulse to the spinal cord.

An impulse has just reached the axon terminal of a neuron. What happens next?

An impulse is passing a particular point on an axon at this instant. What is happening at the membrane there?

A person steps on a sharp stone and a moment later feels the pain. In which order does that signal travel?

A person deliberately wiggles their toes. In which order does the command travel?

An impulse arrives at the end of one neuron, and a narrow fluid-filled gap separates it from the next neuron. How does the signal cross?

What is the junction between the axon terminal of one neuron and the dendrite of the next called?

A drug blocks the receptors on the dendrites of a receiving neuron. Neurotransmitter is still released normally into the synapse. What is the result?

Why does a signal cross a synapse in one direction only?

A signal crosses a synapse when neurotransmitter binds to receptors on the receiving neuron. What normally happens to the neurotransmitter next, so the receiving neuron does not keep firing?

A person's hand jerks away from a hot pan before they are aware of any pain. Which pathway accounts for the speed of the response?

Which statement about reflexes is correct?

A doctor taps the tendon below the knee and the lower leg kicks. Which sequence describes that reflex?

A person touches something sharp and snatches the hand back at once. Which part of the nervous system sends out the command that pulls the hand away?

The hand has already been snatched back, and a moment later the person feels the pain. Which part of the nervous system produces that awareness of pain?

A patient's spinal cord tests as undamaged, but tapping the knee tendon produces no kick and the leg has no feeling. Which part of the nervous system was most likely destroyed?
