About This Chapter
GRE Biology: Male Reproductive Structures - Chapter Summary
Use our video lessons to review the anatomy and functions of male reproductive structures. The lessons cover what you need to know for related questions on the GRE Biology Test, including:
- Accessory gland functions
- Testicular anatomy
- External and internal anatomy
- HPG Axis
- Sperm's path from the testes to the urethral orifice
The lessons in this chapter are less than 10 minutes long and are taught by experts in the field of biology. You can watch the videos as many times as you would like to be sure you understand the concepts discussed by the instructors. We also provide transcripts of the lessons to give you another resource to learn the materials. A chapter exam offers an additional tool for studying male reproductive structures.
GRE Biology Objectives
The GRE Biology Test is a 190 multiple-choice question test offered to graduate school applicants to highlight the breadth of their knowledge of biology. The test is organized into three main subject areas, each of which carry equal weight. They are: cellular and molecular biology, organismal biology, and ecology and evolution. Questions on animal reproduction and development, including male reproductive structures, are asked under the organismal biology subject area and account for 6% of all test questions.
Each test question provides five answers choices. The test is offered three times per year in September, October and April in a paper format.
1. Male Reproductive System: Functions, Organs & Anatomy
Ever wonder what the inside of a male looks like? Find out in this lesson that explores the inner workings of the male reproductive system and the pathway that sperm takes.
2. Male Reproductive System: Accessory Gland Functions
Males require a number of different glands to aid in the production of semen. Find out more about those glands in this lesson covering the male accessory glands.
3. Testicular Anatomy: Structure, Terms & Diagrams
Ever wonder about where sperm is made? Find out in this lesson covering the function and anatomy of the male testes. We'll talk about sperm and testosterone production and how the two work together.
4. Male Reproductive System: External Anatomy
Learn about the structure and function of the external reproductive structures of the male. This includes study of the scrotal sac, the parts of the penis and the erectile tissues.
5. Sperm's Journey from the Testes to Urethral Orifice
Follow newly created sperm as they make their way from their origin of creation, the male testes, all the way to the exit of the male reproductive tract.
6. The HPG Axis: Hormones of Male Reproduction
Do you know how your body communicates? How does the brain get in touch with other parts of the body? In this lesson, you will learn about how the male's brain uses hormones to communicate to the testes as a way of regulating reproduction.
