NCM 107 1M

production of gametes namely the egg cell and sperm

Gametogenesis

development of gametes

Gametogenesis

in female

oogenesis

in males

spermatogenesis

enhances fertilization of the oocyte by the sperm

reproductive system

nourishes the sperm until they are mature

duct system

receives the male's sperm and transport them to fertilization site

female reproductive system

nurtures the development of a new-individual in the uterus until birth

female reproductive system

provides nourishment after birth

growth and nourishment of a new individual

controls development of gender-specific body form

production of reproductive hormones

essential for the normal function of reproductive system and for reproductive behavior

hormones

What are the general functions of the human reproductive system

1. Gametogenesis2. Fertilization3. Growth and Nourishment of a new individual4. Production of reproductive hormones

male reproductive system consists of:

Penis, Scrotum, Testes/Testicles

also known as copulatory organ

penis

conveys both urine and seminal fluid outside the body

penis

externally: shaft, glans penis (enlarged tip), also covered by foreskin which also known as

prepuce

derived from the term pouch

scrotum

divided sack of the skin that hands outside the abdominal cavity

scrotum

located between the legs and the root of the penis

scrotum

functions of scrotum

CONTAINS, ENCLOSES, AND PROTECTS TESTES

contract the skin of the scrotum

Dartos muscle

pull the testes nearer to the body

Cremaster muscle

primary male gonad

testes/testicles

basically released through DUCTS

exocrines products

released directly top the bloodstream

endocrine products

what is the product of exocrine?

sperm cells

products of endocrine?

testosterone

testes/testicles are covered by?

fibrous connective white tissue (TUNICA ALBUGINEA)

differentiate to form spermatozoa (male gamete)

germ cells

nourishes the germ cell

sustentacular cells or sertoli cells

tightly coiled structures considered to be the sperm forming factories

seminiferous tubules

Main and primary gonad of the female

ovary

The parts of the female reproductive system that are located outside of the vagina are called the

external genitalia / Vulva

Fatty rounded area overlying the pubic symphysis

Mons Pubis

After puberty, this area will be covered with pubic hair

Mons Pubis

Fatty tissue covering the pubic bone

Mons Pubis

Two elongated skinfolds

Labia Majora

hair-covered labia majora encloses a region

vaginal vestibule

Enclose and protect the labia minora

Labia Majora

.Protects the external openings of the urethra and the vagina

Labia Minora

Secrete fluid that moistens and lubricates the vaginal vestibule and opening during sexual arousal and coitus

Vestibular Glands

Primary site of sexual arousal

Clitoris

female Internal Structures

Ovaries, Uterine or Fallopian Tube, Uterus and Vagina

Primary female gonad which produce both exocrine and endocrine products

ovaries

Richly supplied with sensory nerve endings

Clitoris

The diamond-shaped region that includes the labial folds and the anus

Perineum

As the egg matures, thefollicle enlarges andbecomes fluid-filed whichis known as a

GRAFFIAN/GRAAFIAN FOLLICLE

exocrine product of the ovary

oocyte or ovum

endocrine products of the ovary

Estrogen and progesterone

internal view reveals many tiny sac-like structures

ovarian follicles

When a developing egg is mature, the follicle ruptures and ejects the egg. This phenomenon is called

OVULATION (release of egg cell)

After ovulation, the ruptured follicle becomes a very different looking structure known as

CORPUS LUTEUM
