Reproductive System Everardo Juarez P.2 - Coggle Diagram

- - - - ovoid structures suspend by spermatic cord outside trunk in a sac, the scrotum
      - Seminiferous tubules are lined with a stratified epithelium that contain spermatogenic cells that give rise sperm cells
      - Channels leading from the seminferous tubulues carry sperm to the epididymis, which continues into the ductus deferns
  - - - Internal
        
        Nurture and transport the sperm cells
        
        epididymis
        
        tightly coiled tube connected tot the testis, leading from the testis to the ducuts deferens
        
        sperm become motile and develop the ability to the fertilize an egg
        
        ductus deferens
        
        muscular tube leading from epididymis into body cavity
        
        united with seminal vesical duct and empties into the ejaculatory duct
        
        seminal vesical
        
        saclike strucutre attacted to the vas deferens near the base pf the urinary bladder
        
        Prostate gland
        
        secertes a thin milky fluid that contains citrate a nutrient for sperm and prostate specific antigen, an enzyme which helps to liquefy semen
        
        Bulbourethral glands
        
        are small glands located inferior to prostate gland
      - External
        
        scrotum
        
        pouch of skin and subscutaneous tissue that houses the testes
        
        protects and helps regualate the tempt. of the testes
        
        penis
        
        contains specialized erectile tissue
        
        cylindrical organ that conveys both urine and semen to the outside
- - - - soild, ovoid strucutres located within the lateral wall of the pelvic cavity
      - the ovaries are subdivided into an inner medualla and an outer cortex
        
        medulaa: is made up of connective tissues, blood vessels, lymphatic vessels, and nerves
        
        cortex: contains ovarian follicles and is covered by cuboidal epithelium
  - - - Uterine tubes
        
        near ovaries, they expand to form an infundibulum wirh fingerlike fimbriae on its margin
        
        cells lining the tubes have cilla
        
        normal site of fertlization
      - Uterus
        
        Upper two-thirds of the uterus, the body, has a dome-shaped top, the fundus
        
        Uterine wall has three layers: an inner, glandular endometrium, a muscular wall or myometrium, and and perimentrium
        
        lower one-third of the uterus is the cervix, which extends into the vagina
      - Vagina
        
        vaginal orifice is paratillay covered by a membrance called the hymen
    - - labia minora
        
        flattened, longitudinal folds between the labia majora
        
        form a hood around the clitors
      - clitoris
        
        small projection at anterior end of vulva, between labia minora
        
        corresponds to the penis and has a similar structure
        
        contains coloumns of erectile tissue
      - labia major
        
        anterior ends meet to form the mons pubis, which covers the public symphysis
      - vestibule
        
        space enclosed by the labia minora, into which the vagina and urethra open
        
        vestibular glands lie on either side of the vaginal opening; correspond to bulbourethral glands and provide lubrication
- - - - secreted by the hypothalamus
      - triggers the production of gontropins from anterior pituitary gland
        
        luteinzing hormone(LH): promotes development of interstitial cells of the testes, which then secrete male hormones
        
        follicle-stimulating hormone(FSH): stimulates sertoli cells of seminiferous tubulues to respond to testosterone
  - - - male sex hormones;testosterone is the most important one
    - - stimulates development of male reproductive organs
      - responsible for male secondary sexual characteristics
