Flashcards

Reproductive System

The system responsible for producing sex hormones, gametes, and for supporting the development of the embryo

Nervous System

The system that controls and coordinates all bodily functions and activities, including communication, senses, and movement. It is often compared to a superhighway for signals.

Endocrine System

This system is responsible for regulating long-term processes like growth, metabolism, and reproduction through chemical signals, such as hormones, which are released directly into the bloodstream.

Fertilization

The process where a sperm and an egg unite, leading to the formation of a zygote, the first cell of a new organism

Study Notes

Coordinated Functions of Reproductive, Nervous, and Endocrine System

  • The presentation discusses the coordinated functions of the reproductive, nervous, and endocrine systems.
  • Learning objectives focus on the role of hormones, identifying organs, describing menstrual cycles, and understanding nervous system coordination for homeostasis.
  • Learning objectives explain the role of hormones, the organs involved, the events of the menstrual cycle and feedback mechanisms.
  • The learning objectives also explain how the nervous system coordinates and regulates these feedback mechanisms to maintain homeostasis.
  • The learning objectives also cover male and female reproductive systems and their hormones.

The Human Reproductive System and Regulatory Processes

  • The presentation covers the human reproductive system and its regulatory processes.
  • Different structures of the female reproductive system like the ovaries, fallopian tubes, uterus, and vagina are outlined.
  • The different structures of the male reproductive system, such as the testes, epididymis, vas deferens, ejaculatory ducts, and urethra are highlighted.
  • The role of accessory glands in adding seminal fluid to semen is discussed including the seminal vesicles, prostate, and bulbourethral glands.
  • The role of the spongy internal tissue of the penis for sexual function is explored.

General Functions

  • The female reproductive system produces eggs, facilitates fertilization, and supports the developing embryo.
  • The male reproductive system produces and delivers sperm.

The Menstrual Cycle

  • The menstrual cycle describes a series of events a woman's body undergoes monthly to prepare for conception.

  • The stages of the menstrual cycle are: menstruation, follicular phase, ovulation, and luteal phase.

  • Hormones play a crucial role regulating the menstrual cycle, including FSH, LH, estrogen, and progesterone.

Feedback Mechanisms

  • Feedback mechanisms are physiological regulatory systems that maintain homeostasis in the body.
  • Positive feedback mechanisms amplify deviations, bringing about changes in the output.
  • Negative feedback mechanisms regulate variable factors towards homeostasis.

Spermatogenesis

  • The testes produce millions of sperms daily via the process of spermatogenesis.
  • Spermatogenesis occurs within the seminiferous tubules of the testes.
  • Sperms mature in the epididymis.

Reproductive Ducts

  • The epididymis, vas deferens, ejaculatory ducts, and urethra form a four-part transportation system in the male.
  • Sperm matures as it moves through the coiled duct of the epididymis
  • Sperm is expelled into the vas deferens during ejaculation.

Accessory Reproductive Glands

  • Sperm cells depend on seminal fluid for movement and survival.
  • The accessory reproductive glands, (seminal vesicles, prostate, and bulbourethral glands), produce the seminal fluid.

Spongy Internal Tissue: Key to the Reproductive Function of the Penis

  • The penis is the part of the male external genitalia, composed of three columns of tissue.
  • The corpora cavernosa and the corpus spongiosum fill with blood during arousal and intercourse, causing the penis to stiffen.
