About This Chapter
ASVAB: The Human Nervous System - Chapter Summary
The video lessons break down the functions of the human nervous system and much more. You'll be well-prepared for addressing ASVAB items about any of these issues, as well:
- Sympathetic and parasympathetic nervous systems and feedback types
- The cerebral cortex
- Central and peripheral nervous systems
- The lobes of the human brain
Learning this material is made easy by professional instructors who will guide you through the chapter's video and text components. Video tags can be used to pinpoint any content that you'd like to see again before you're completely finished with this chapter.
Objectives of the ASVAB: The Human Nervous System Chapter
The ASVAB is used to check your knowledge of content across several subject areas and compare it with specifications for joining the military. The practice quizzes throughout the chapter for each lesson give you an idea of how some of the questions you're asked in the General Science subtest of the ASVAB could look. You'll be answering 25 questions in the paper version of the GS subtest, and 16 within the computer-based GS subtest. Any exam questions about the material in this chapter will be in multiple-choice format.
1. Functions of the Nervous System
In this lesson, we'll watch Timmy as he plays in his backyard. Watch what happens when he tries to catch a butterfly, hears a mean dog bark, and scrapes his knee. All of Timmy's reactions are tied to his nervous system. For a full explanation of what goes on in the human nervous system, check out the video!
2. The Central and Peripheral Nervous Systems
Did you know that hammerhead sharks and platypuses share a special type of sensory neuron that humans and most other animals don't have? In this lesson, you'll find out what that sensory neuron and a whole lot of others can do. You'll also learn how the nervous system is organized and the differences between the central and peripheral nervous systems.
3. The Sympathetic and Parasympathetic Nervous Systems
In this lesson, you'll learn about two subdivisions of the autonomic nervous system - the sympathetic and parasympathetic nervous systems. Watch as a hiker, Phil, runs away from a terrifying bear and see how these systems react to the impending danger!
4. Brain Structures and Functions Part I
The brain's complexity can often be difficult to understand because it serves so many important functions. In this lesson, you'll get a little help from Nrr, the alien biologist, who will guide you through understanding the structure and functions of the human brain.
5. The Cerebral Cortex: Brain Structures and Functions Part II
Check out this video lesson to learn about the four lobes of the human brain - the frontal, parietal, occipital and temporal. You'll learn about the functions and processes of each region.
6. Homeostasis and Temperature Regulation in Humans
Do you wonder how your body is able to maintain a consistent temperature? Have you ever questioned why you get goosebumps when you're cold? This lesson will introduce you to homeostasis and answer your questions about body temperature regulation and reactions, like goosebumps.
7. Positive and Negative Feedback in the Sympathetic and Parasympathetic Nervous System
In this lesson, you'll study positive and negative feedback in the sympathetic and parasympathetic nervous systems. You'll also learn why we have a fight or flight instinct and how it works.
