Part of spermatozoa that contains genetic information
|
• The head contains the nucleus with genetic material,
|
|
|
Ovulation definition
|
Ovulation is the process in a female's menstrual cycle by which a mature ovarian follicle ruptures and discharges an ovum
About day 14 Surge of LH causes ovum to burst Ruptured follicle transforms into corpus luteum |
|
|
Semen
|
• Mixture of sperm and secretions of accessory sex glands
• Averages 3-5 mL per ejaculation • Each mL containing about 100,000,000 sperm • Sperm passes through the ejaculatory ducts and mixes with fluids from the seminal vesicles, the prostate, and the bulbourethral glands to form the semen. |
|
|
Chromosomes
|
hromosome is an organized building of DNA and protein that is found in cells. It is a single piece of coiled DNA containing many genes, basic unit of heredity
|
|
|
Secondary sex Characteristics
|
Develops secondary sex characteristics:
• Deeper voice • Broader shoulders • Narrower hips • Mores body hair • Protein anabolism • Development of muscle strength (more muscle tissue) |
|
|
Sex cells # of chromosomes

|
location and function of ovaries
|
• Paired glands weighing about 3 g each
• Resemble large almonds • Located in region called ovarian fossa • Attached to ovarian ligaments in pelvic cavity on each side of uterus |
|
|
Seminal Vessicles
|
• Seminal vesicles produce a yellowish viscous fluid rich in fructose and other substances that makes up about 70% of human semen.
|
|
|
Spermatic cord
|
The spermatic cord is the name given to the cord-like structure in males formed by the ductus deferens and surrounding tissue that run from the abdomen down to each testicle. Contains arteries and nerves
|
|
|
what do testes produce?
|
Sperm
|
|
|
Where is sperm stored?
|
Epidydimis
|
|
|
Ovaries Ligaments
|
The ovarian ligament (also called the utero-ovarian ligament or proper ovarian ligament) is a fibrous ligament that connects the ovary to the lateral surface of the uter
suspensory ligament of the ovary, also infundibulopelvic ligament (commonly abbreviated IP ligament or simply IP), is a fold of peritoneum[1] that extends out from the ovary to the wall of the pelvis |
|
|
Acrosome in sperm
|
• acrosome, which contains enzymes used for penetrating the female egg. It aids in penetration of the ovum.
|
|
|
Menopause
|
• Menstruation ceases
• Normal ovarian function declines • Follicles stop ripening • No appreciable amounts of estrogen produced • Uterus, oviducts, vagina, vulva become somewhat atrophied • Vaginal mucosa becomes thinner, dryer, more sensitive |
|
|
Spermatogenesis
|
1. Sperm precursor cells; Spermatogonia
2. Meiosis produces primary spermatocyte 3. Forms four spermatids with 23 chromosomes 4. Spermatids mature into Spermatozoa spermatogonia ----> spermatocytes ------> spermatids -----> sperm |
|
|
OOgenesis
|
• Oogonium becomes Primary Oocyte
• Meiosis • First Polar Body (Discarded) + Secondary oocyte form • Meiosis II • Secondary Polar Body (Discarded afterward) + Ovum formed |
