LL- Nervous System

A student practiced a ruler-drop test 10 times to see if their reaction time improved. The graph below shows the data from their trials.
What is being changed or tracked on the x-axis?

Neurons can be "myelinated" (have a fatty insulation) or "unmyelinated." This graph compares how fast an electrical signal travels in both types.
If a disease like Multiple Sclerosis (MS) were to damage the myelin sheath of a neuron, how would you expect its bar on this graph to change?

The nervous system uses "Action Potentials" (electrical signals) to send messages. This graph shows how a sensory neuron in your skin responds to different levels of pressure. Look at the height (amplitude) of the spikes. Does a stronger stimulus create a "bigger" electrical signal, or just "more frequent" signals? Use the graph to justify your answer.

The Sympathetic and Parasympathetic nervous systems are part of the :

Which part of the neuron receives signals from other neurons?

The part of the brain that controls controls balance and condination.

The part of the brain that controls controls memory, intelligence, muscles.

The part of the brain that controls controls involuntary activities such as heart rate and breathing
