30 Questions
What is the general function of the brain and nervous system?
Take in information from the outside world and our bodies, and work out the best course of action, causing changes in our bodies to enable that action to happen.
What is the purpose of exploring the structures, circuits, and cells of the nervous system?
To understand broadly how information flows into, through, and from the brain, and how these structures and cells generate behaviors and internal responses.
What are the biological structures and processes that enable us to exist and interact with the world?
Our thoughts and actions.
What are some examples of behaviors that the brain and nervous system enable us to perform?
Running away from a lion, catching a ball, or going to sleep.
What is the main focus of the following chapters of the book?
To learn more about how the structures and cells of the nervous system generate behaviors and internal responses.
Why is it important to learn about the different parts of the nervous system?
To understand how information flows into, through, and from the brain, and how it generates behaviors and internal responses.
What is the nervous system compared to in the text?
a computer
What are the two main parts of the nervous system?
central nervous system and peripheral nervous system
What structures make up the central nervous system?
brain and spinal cord
How is the peripheral nervous system (PNS) described in terms of symmetry?
Symmetry around the midline is a general feature of nervous system organisation
What are the two subdivisions of the peripheral nervous system (PNS)?
somatic and autonomic nervous systems
What does the autonomic nervous system further subdivide into?
three further divisions
What is the primary function of the nervous system, as mentioned in the text?
detecting something, transmitting information, integrating it with other information, and sending an instruction to other parts of the body
What determines the program run by a given cell or structure in the nervous system?
how that cell or structure is connected to other cells or structures, and the biological rules that govern those connections and how they change over time
What is the role of the peripheral nervous system in relation to the central nervous system?
It provides the input to the CNS, which computes what to do with that information, and sends outputs back to the body via the PNS
What is the function of the cranial nerves in the peripheral nervous system?
connect to the brain
What is the primary function of the brain and nervous system as mentioned in the text?
Generating thoughts and actions
What is the purpose of exploring the structures, circuits, and cells of the nervous system?
To grasp how information flows into, through, and from the brain
How is the peripheral nervous system (PNS) described in terms of symmetry?
Asymmetrically distributed nerves
What determines the program run by a given cell or structure in the nervous system?
A combination of internal and external factors
What structures make up the central nervous system?
Brain and spinal cord
What are some examples of behaviors that the brain and nervous system enable us to perform?
Reading and writing
What is the role of the autonomic nervous system?
It controls involuntary bodily functions like heart rate and digestion
How does the nervous system function similar to a computer, as mentioned in the text?
By integrating information and sending instructions to other parts of the body
What does the central nervous system comprise?
The brain and the spinal cord
What is the primary function of the peripheral nervous system?
To connect the CNS with the rest of the body
What determines the program run by a given cell or structure in the nervous system?
The biological rules that govern connections with other cells
What are the two main parts of the nervous system?
Central and peripheral nervous systems
What is a general feature of nervous system organization?
Symmetry around the midline
What would be an example of an output generated by a nerve cell in the context mentioned in the text?
Forming patterns of muscle contractions to make you run
Explore the biological structures and processes that enable us to exist and interact with the world, performing behaviors that keep us fed, watered, and safe. Learn about the different parts of the nervous system that orchestrate these behaviors, and consider the general functions of our brains and the nervous system in processing external information.
