Ch 28: Praxis Biology & General Science: Nervous & Endocrine Systems

About This Chapter

Explore human anatomy and physiology through this chapter. The video lessons and self-assessment quizzes can help you correctly answer questions about diversity of life, plants and animals on the Praxis II: Biology and General Science test.

Anatomy and Physiology II - Chapter Summary

Learn about the brain and nervous system through these short, engaging video presentations. This is the second of two chapters on anatomy and physiology; complete them both in preparation for the Praxis II: Biology and General Science test.

Our team of professional educators, who have experience in anatomy and physiology, will teach you about functions of the nervous system, as well as the structure and function of neurons. This chapter also addresses antibiotics and vaccines. Additional topics covered in these video lessons include the following:

  • The central and peripheral nervous systems
  • The sympathetic and parasympathetic nervous systems
  • Brain structures and functions
  • The cerebral cortex
  • Innate and acquired immunity
  • Flu viruses, HIV and immune system evasion
  • Antibiotic resistance and virulence
  • The endocrine system
  • Hormones
  • Positive and negative feedback in the sympathetic and parasympathetic nervous systems

Anatomy and Physiology II Objectives

Approximately 17% of the questions on the Praxis II: Biology and General Science test cover diversity of life, plants and animals, which includes anatomy and physiology. A number of states use this test, which is comprised of 120 multiple-choice questions, as part of the certification process for high school science teachers. You'll have two hours to complete the Praxis II.

You can prepare for the test using the three components in each lesson of this chapter. These include a video lesson, transcript and self-assessment quiz. The purpose of the quizzes is twofold: They allow you to measure your mastery of anatomy and physiology and introduce you to multiple-choice questions like those you'll encounter on the Praxis II.

Functions of the Nervous System

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!

The Structure and Function of Neurons

2. The Structure and Function of Neurons

In this video lesson, you'll learn about neurons, which are specialized cells in the nervous system. Check out how far neurons can send signals throughout the body and how depolarization is much like 'the wave' at a football game.

The Central and Peripheral Nervous Systems

3. 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.

The Sympathetic and Parasympathetic Nervous Systems

4. 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!

Brain Structures and Functions Part I

5. 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.

The Cerebral Cortex: Brain Structures and Functions Part II

6. 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.

Innate Immunity: Inflammation, Neutrophils & Natural Killer Cells

7. Innate Immunity: Inflammation, Neutrophils & Natural Killer Cells

You might already know how your body handles known infectious agents but how about unknown? Watch this video to explore your innate immune system - your body's defense against new bacteria and viruses.

Acquired Immunity: T Cells, B Cells and Antibodies

8. Acquired Immunity: T Cells, B Cells and Antibodies

Have you ever wondered why some people don't ever seem to get sick? These people likely have an acquired immunity. Learn more about the immune system and how exposure to an illness one time can help your body to prevent that illness from ever occurring again.

Antibiotics and Vaccines

9. Antibiotics and Vaccines

Do you know why children must get regularly vaccinated? Have you ever wondered how an antibiotic works and why they are so widely prescribed? If so, this lesson will help you to understand how changes in medicine have almost eliminated several deadly diseases and added decades to the average person's lifespan.

Flu Viruses, HIV and Immune System Evasion

10. Flu Viruses, HIV and Immune System Evasion

Why is it that our immune systems can protect us from some viruses but not others? We've eradicated smallpox by using vaccines, so why do influenza and HIV remain such dangerous health risks? In this lesson about viruses, we'll explore these questions and learn how influenza and HIV continue to evade the human immune system.

Pathogens: Antibiotic Resistance and Virulence

11. Pathogens: Antibiotic Resistance and Virulence

Find out more about how the overuse of antibiotics could lead to some serious problems with epidemics or untreatable diseases in the future. You can also discover some of the things that make pathogens harmful and why pathogens don't cause disease in every species they infect.

Endocrine System Function & Hormone Regulation

12. Endocrine System Function & Hormone Regulation

Our hormones play a big part in how we feel and behave throughout the day. Hormones also affect important bodily functions. What other functions do our hormones regulate? Find out in this lesson on the endocrine system!

Hormones: Definition, Function & Intro to the Endocrine System

13. Hormones: Definition, Function & Intro to the Endocrine System

This lesson introduces the endocrine system and provides a brief overview of each endocrine gland. It also provides the definition of hormones and describes their general function inside the body.

Positive and Negative Feedback in the Sympathetic and Parasympathetic Nervous System

14. 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.
