The Reproductive System Kaylee Martin Period 1
hormones of the reproductive system and their regulation
Follicle-stimulating hormone and luteinizing hormone
Luteinizing hormone (LH)
LH is produced in the anterior pituitary. It acts on the interstitial cells in the male to secrete testosterone.
events of the female hormonal cycles
hormonal interactions of the ovarian cycle
anatomy of all major male and female reproductive structures
2) Penis: A copulatory organ that delivers sperm into the female reprouctive tract.
3)Testis: The testes is surrounded by two tunics. The outer layered tunica vaginalis and the tunica albuginea.
1) Ducts: The ductus deferens transports sperm during ejaculation. After entering the prostate, each ejactulatory duct empties into the urethra,
4)Scrotum: a sac of skin and superficial fascia that hangs outside of the abdominopelvic cavity at the root of the penis. It has hairs and oval testes covering it. :
5)Accessory glands: Include the paired seminal glands and bulbo-urethral glands and the single prostate.
5) external genitilia: mons pubis is fatty rounded area overliyng the pubic symphylis. The vulva is the female reproductive system that lies externally to the vagina.
4) Uterus: Lies in the pelvic cavity anterior to the rectum and posterosuperior to the bladder.
3) Ovary: Produce female gametes and the sex hormones estrogens and progesterone.
2) uterine tube: Fallopian tubes form the initial part of the female duct system. They also recieve the ovulated ocoyte and are the uterine tube pf peritoneal cavity.
1) Vagina: A thin walled tube that lies between the bladder and the rectum. it also extends from the cervix to the body exterior.
formation of gametes
4) TELOPHASE: the reappearance of the nuclear membrane and division of the cytoplasm
3) ANAPHASE: separation of the tetrads
2)METAPHASE: to ensure the separation of the chromosomes in the tetrad, the centromeres must first attach to spindle fibers
5) ANAPHASE 2: chromosomes are pulled apart as the spindle fibers shorten
1) PROPHASE:the homologous chromosomes attach to one another in a formation known as a tetrad
6)TELOPHASE 2: last stage of the second division cycle
four cells are created during cytokinesis
major functions of the reproductive system
3) Support the development of the fetus and birth of the baby.
4) Combine the genetic information contained in the female and in the male gametes. It is also known as the process called fertilization.
2) Bring the gametes from the male and female together. Sexual intercourse delivers the male gametes to the female.
1) form specialized cells for sexual reproduction which are called gametes. It is the sperm in males and the ova(eggs) in females.
disorders of the reproductive system(SYI, STD)
Sexually transmitted infections(STI): infectious diseases spread through sexual contact.
Chlamydia: Most common bacterial STI in the US. It is a bacterium with a viruslike dependence on host cells.
Gonorrhea: Invades the mucosae of the reproductive and urinary tracts.
Syphilis: Caused by the corkscrew-shaped bacterium treponema pallidum and is transimitted sexually but can be contrtacted from an infected mother.
