Reproductive Flashcards
Endoderm
Epithelial lining of GI tract (except oral)
AND gametes
Mesoderm
All skeletal and cardiac muscle tissue and most smooth muscle tissues.
Blood.
Gonads and genital ducts
Adrenal Cortex
Ectoderm
All Nervous tissue
Epidermis of skin
Chorion hormone
secretes estrogen and progesterone to inhibit menstruation
Relaxin hormone
Secreted by corpus luteum. Increases flexibility of pubic symphysis and ligaments. Helps dilate cervix during labor
hCS or hPL hormones
preps mammary glands
True Labor Stages
- Stage of Dilation
- Expulsion
- Placental Stage
Prolactin hormone
secreted by anterior pituitary gland. Main hormone for milk production
Oxytocin Hormone
Cause of release of milk via milk ejection reflex
Alleles
Genes for the same trait that are in the same location.
Dominant allele: dominates other allele
Newborn PKU
Tests for phenylalanine hydroxylase enzyme
Genotype
Actual genetic makeup
Dominant-Recessive inheritance pattern
Aa or Bb. Dominant allele
Incomplete Dominance
neither member of the pair of alleles is dominant over the other.
Sickle cell anemia
Multiple inheritance
Genes have more than two alternative forms (ie ABO blood groups)
Codominance
Like Type A and B blood being expressed equally
Polygenic inheritance
trait is controlled by combined effects of two or more genes
Complex inheritance
trait occurs from combined effects of many genes and environmental factors (skin color, height, body build, hair and eye color)
Karyotype
chromosome arranged according to position of centromere
Sex-linked trait example
Red-green color blindness.
Non-sexual traits inherited on X chromosome
Dartos Muscle
Separates testes in scrotum
LH in males
Males: stimulates testosterone
FSH
Males: stimulates spermatogenesis; negative feedback indirectly
Testosterone
Negative feedback; prenatal development, sexual function and characteristics
Travel of sperm
Seminiferous tubules, straight tubules, rete testis, efferent ducts, to epididymis (where sperm mature) to vas deferens to spermatic cord
Seminal Vesicles
secrete alkaline viscous fluid with fructose and clotting protiens
Prostate
secretes milky slightly acidic fluid with citric acid.
Every fluid has prostate but is super high in ejaculate
Bulbourethral gland
secrete alkaline fluid during sexual arousal that neutralized acids
Corpus Luteum produces hormones…
Progesterone, estrogen, and inhibin.
Develops after ovulation.
