Reproduction in Vertebrates - The cessation of menstrual cycles at the end of a woman’s reproductive period is termed menopause. The average age of menopause in women is 52 years, but it can occur anytime between 45 and The Uterine Cycle: High estrogen and progesterone levels stimulate increased endometrial thickness, but following their decline from a lack of. Define reproductive cycle. reproductive cycle synonyms, reproductive cycle pronunciation, reproductive cycle translation, English dictionary definition of reproductive cycle. adj. Good as the film is, it fails to reproduce the atmosphere of the book; "Sheep have very similar reproductive cycles to humans.". In females, FSH and LH cause estrogen and progesterone to be produced. They regulate the female reproductive system which is divided into the ovarian cycle and the menstrual cycle. Menopause occurs when the ovaries lose their sensitivity to FSH and LH and the female reproductive cycles slow to a stop. Fertilization and Early Embryonic.

Further books and numerous scientific publications followed, on vertebrate reproductive cycles, hormones, mitosis and chalones, establishing his world-wide reputation for scientific excellence. Professor Bullough was also a gifted teacher: he took his work and enthusiasm to a wider audience with television programmes. Ovarian Cycles. After puberty the ovary cycles between a follicular phase (maturing follicles) and a luteal phase (presence of the corpus luteum). These cyclic phases are interrupted only by pregnancy and continue until menopause, when reproductive capability ends. The ovarian cycle lasts usually 28 days. In vertebrate species that undergo metamorphosis, such as amphibians, surges of T 3 are responsible for initiating development of new structures, reorganization of internal organ systems, and other processes that occur during metamorphosis. In insects, metamorphosis is controlled by a set of hormones that determine whether the animal grows into. 1. Author(s): Bullough,William S(William Sydney), Title(s): Vertebrate sexual cycles.

In the first phase of the menstrual cycle, a follicle (the cell complex that surrounds and nurtures the egg) grows in the ovary, while the lining of the uterus builds up to receive a fertilized mid-cycle, when the egg is ready, the ovary releases the egg. This stage is called ovulation, and is the optimum time for fertilization to take place. The story of invertebrate gametes-their structure, origin, composition, physiology, and production mechanisms-was told in Volumes I and II; how accessory sex gland secretions facilitate their packaging, storage, survival, and delivery in Volume III; events leading to and following the union of gametes such as insemination, sperm-egg interaction, fertilization, development, embryonic nutrition Author: R.

By the end of this section, you will be able to: Some vertebrate animals—such as certain reptiles, amphibians, and fish—also reproduce through parthenogenesis. Sexual reproduction is the combination of reproductive cells from two individuals to form genetically unique offspring. The Author: Charles Molnar, Jane Gair, Molnar, Charles, Gair, Jane.

With a background in comparative reproduction and endocrinology, she is an editor of the fi ve-volume work Hormones and Reproduction of Vertebrates (Academic Press, ).

In biology, a biological life cycle (or just life cycle or lifecycle when the biological context is clear) is a series of changes in form that an organism undergoes, returning to the starting state. "The concept is closely related to those of the life history, development and ontogeny, but differs from them in stressing renewal." Transitions of form may involve growth, asexual reproduction, or.

It ends with atrophic changes in the sex organs and the gradual suppression of sexual activity. In the human species, puberty occurs from 13 to 15 years of age, being usually a little earlier in girls than in boys. Male Reproductive System As stated earlier, the primary reproductive organs in males are the testes (singular – testis) (3) which are housed externally in a pouch of skin, the scrotum (2).

The testes descend from the inguinal canal within the body cavity before or shortly after Size: KB. With a background in comparative reproduction and endocrinology, she is an editor of the five-volume work Hormones and Reproduction of Vertebrates (Academic Press, ).

This process prepares the egg for ovulation. As the follicles grow, they begin releasing estrogens and a low level of progesterone. Progesterone maintains the Author: Charles Molnar, Jane Gair, Molnar, Charles, Gair, Jane.

Reproductive System Most ectotherms are r-strategists because they rely on external sources of heat. They have the disadvantage of being vulnerable to fluctuations in external temperature, which means that the risk of losing offspring to random environmental factors is high.

This book surveys the sexual physiology of vertebrates. The cyclic breeding habit is introduced in the first chapter: the major cycle of the life span, within this the seasonal reproductive cycles, and within these the oestrous cycles typical of mammals.

The reproductive structures that evolved in land animals allow males and females to mate, fertilize internally, and support the growth and development of offspring. Book: Concepts in Biology (OpenStax) The human male and female reproductive cycles are controlled by the interaction of hormones from the hypothalamus and anterior pituitary with hormones from reproductive tissues and organs.
