Students will review:
In this chapter, you'll learn the answers to questions including:
- What are the main concepts associated with animal reproduction and development?
- How is the external anatomy of male reproductive systems structured?
- How is the internal anatomy of female reproductive systems organized?
- In what ways do mammalian placentas nourish fetuses?
1. Overview of Animal Reproduction and Development
At this stage in life, you likely know where babies come from. However, did you know that some animals can make clones of themselves and reproduce sexually too? In this lesson, you'll learn more about sexual reproduction and early vertebrate development.
2. 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.
3. Female Reproductive System: Internal Anatomy
Ever wonder where a female produces her eggs or how they get from the ovary to the uterus? Find out in this lesson about the internal reproductive anatomy of females.
4. What is a Fetus? - Growth & Position
A fetus is the term for a developing baby in the uterus from week 11 until the time of birth. Read on to learn more about the growth and development of a fetus, then quiz yourself.
5. What is the Amniotic Sac? - Definition & Function
This lesson is going to discuss what the amniotic sac is and the many functions it serves inside of the amniotic egg. We will discuss how the functions are carried out in the egg.
6. What is a Reproductive Strategy?
This lesson defines a reproductive strategy. You'll also learn the various characteristics of two main reproductive strategies and how that impacts the chances offspring will survive.
7. The Coolidge Effect in Psychology
The Coolidge Effect is a phenomenon based on mammal sexuality and why men specifically get tired of having sex with the same partner over time. This lesson explores the effect and its origins and why new women reinvigorate sexuality in men.
8. What is a Liger? - Size, Reproduction & Facts
Ligers and tigons and grolar bears, oh my! This lesson discusses animal hybrids in general and ligers in particular. Learn about the origins, characteristics, and cautions of this fascinating man-made animal.
9. What is a Tigon? - Size, History & Facts
What is a tigon? Are they some strange beast that descended from saber tooth tigers? In this lesson, we will explore the answer to that question, as well as where the name tigon originated. The answers may surprise you.
