Nervous System
This division of the nervous system is made up of the brain and spinal cord. It also houses 99 percent of all nerve cells in our bodies.
What is the Central Nervous System (CNS)?
Disruption to this area of the neuron could prevent chemicals from being released into the synapse, leading to disruption of neuronal communication
What are the terminal buttons?
Marcelo is taking a yoga class to help with attention and balance. Which area is activated when Marcelo is trying out new postures to specifically improve his balance on one leg?
What is the cerebellum?
What is the Hypothalamus?
This lobe, located behind the forehead, is responsible for executive functioning, higher order cognition, personality, and control of voluntary muscles.
This subdivision of the peripheral nervous system consists of sensory and motor nerves. Sensory nerves convey information from the skin and muscles to the CNS about conditions such as pain and temperature. Motor nerves tell the muscles what to do.
What is the Somatic Nervous System?
Adding more or less of this part of the neuron could speed up or slow down the action potential, or electrical signal, that is sent down the neuron.
What is the myelin sheath?
Which area of the brain is associated with respiration, bladder control, head and eye movement, facial expressions, and regulating REM sleep?
What is the Pons?
Elias is out camping with some friends when they see a bear. He and his friends experienced intense fear during that experience, and they all had different reactions where some froze and some ran. Which brain area would be responsible for the emotional response to the bear, and their reactions?
What is the amygdala?
This lobe, located at the top and rear of the head, is responsible for spatial location, attention, and motor control.
What is the Parietal Lobe?
This division of the nervous system is the network of nerves that connects the brain and spinal cord to the other parts of the body, and carries out the commands of the CNS to execute various muscular and glandular activities.
What is the Peripheral Nervous System (PNS)?
Unlike the other areas, which part of the neuron isn't directly linked to either chemical or electrical signaling but is responsible in keeping the neuron alive?
What is the cell body?
Out of all areas of the brain, damage to which area would be most likely to lead to immediate death as it controls our basic functions, such as heart rate and breathing?
What is the medulla oblongata?
Which area of the brain would be activated while remembering the route that you take to work every day?
What is the hippocampus?
This lobe, located at the rear and bottom of the head, is responsible for receiving and interpreting information from the eyes via the optic nerve.
This subdivision of the peripheral nervous system takes messages to and from the body's internal organs. It also monitors processes such as breathing, heart rate, and digestion.
What is the autonomic nervous system?
Where does the electrical signal, also known as the action potential, primarily take place?
What is the axon?
Being alert in class is related to our ability to maintain arousal in the brain. Which structure of the brain is this linked to?
What are the reticular formation?
Which area is responsible for the physical maturation that occurs during puberty?
What is the pituitary gland?
This lobe, located above the ears on each hemisphere, is responsible for receiving and interpreting aural sensations, and organizing memory along with other structures.
What are the Temporal Lobes?
These two sub-subdivision of the nervous system are involved in the body's "fight-or-flight" response when experiencing stress or danger, and calming the body back down once the stress/danger is gone. When these two systems are active, you experience the increase and decrease of many physiological symptoms.
What are the sympathetic and parasympathetic nervous systems?
The more connections to this area of the neuron, the more likely a neuron is to receive chemical input from multiple other sources.
What are dendrites?
This structure is a major producer of dopamine, the neurotransmitter involved in much of human functioning, personality, emotion, and cognition. Parkinson's disease causes significant damage to this area.
What is the Substantia Nigra?
This structure is responsible for working with the cerebellum and cerebral cortex to control & coordinate voluntary and habitual movements. Damage to this area can cause unwanted or lack of movement.
What is the Basal Ganglia?
This massive bundle of nerves connects the two hemispheres of the brain together.
What is the Corpus Callosum?
