Exam 3: The Human Brain

The human brain is organized in the simplest manner possible,with each side controlling the functions of the same side of the body.

When one neuron sends a message to another neuron instructing it not to fire,this process is known as __________.

__________ are responsible for sending a message from the presynaptic neuron to the postsynaptic neuron.

The occipital lobe of the cerebral cortex,located at the bottom of the back of your brain,is responsible for processing input from which of your sensory systems?

Paul Broca discovered a section of the frontal lobe of the cerebral cortex that controls which aspect of speech?

A neuron's axon can "talk to" one of three different targets.Which of the following is one of those possible targets?

It is the movement of positively and negatively charged particles,called __________,that allow an electrical signal to travel down a neuron's axon.

Spatial relationships are primarily controlled by which part of the brain?

Tiny little bits of axon are exposed when the myelin sheath pinches in.The areas where the axon is exposed are called the __________.

Renata was walking to her car in a dark parking lot,when she heard a strange noise and footsteps behind her.She felt her heart start to race,her breathing got faster and shorter,and the pupils of her eyes dilated.From your study of psychology,which part of Renata's nervous system was activated?

While you are taking a walk through a park,you notice that there is a small pond that has a bunch of lily pads in it.As you stand watching,a frog comes along and hops quickly from one end of the pond to the other by hitting a series of lily pads in a row.After this takes place,you start to think to yourself "That is just like a neuron,when the action potential jumps from one __________ to another."

What happens to an action potential when it comes to one of the nodes of Ranvier?

In order for the neuron to "fire," what does the soma need to receive?

What shape does the amygdala resemble? (hint: it gets its name because in Greek "amygdala" means this kind of nut!)

Once a neurotransmitter is released into a synapse,it stays there until it finds a receptor site on the surface of the next neuron's dendrite.

As you watch your favorite team play football on a brisk Sunday afternoon,you start thinking back to your recent lecture on neuropsychology.You watch as the quarterback sends a blistering pass to the wide receiver,who takes the ball and heads upfield with it.If you were to relate this scene to a neuron's activities,which football player would represent the presynaptic neuron?

Which of the following is a part of the brainstem?

Why is it that when people suffer serious spinal cord injuries that they are not able to regain control of functions lost as a result of the injury?

Each lobe of the cerebral cortex contains two main areas - a primary cortex and an association cortex.

The human brain is set up so that the cerebral hemispheres always control functions on the opposite side of the body.This is the basis of contralateral connectivity.
