Endocrine System

O Endocrine System : The endocrine system regulates the functions of the organs in the body by using all of the glands and the hormones they produce to maintain homeostasis.

Gonad Glands

LocationO Gonads in the female

body are the ovaries, located inside the abdomen.

O The male gonads are called testicles, located in the scrotum.

Role and Function

OMake gametes or haploid germ cells

OSex cells are the gametes

Hormones Secreted

OTestosterone

OProgesterone

OEstrogen

Testosterone

O Increased growth of body hair on face, chest, axillary region, pubic region, lowers voice, thickening of skin.

Progesterone

O Promote change in the uterus during the female reproductive cycle, affects the mammary glands, and regulates gonadotropins from the anterior pituitary

EstrogenO Development of the breasts and the ductile

system of the mammary glands in the breasts

O Increased disposition of adipose tissue in the subcutaneous layer generally and in the breasts, thighs and buttochs particularly

O Increased vascularization of the skin.

CancerO Testicular Cancer

O Causes: exact cause is unknownO Abnormal testicle developmentO Klinefelter Syndrome

O SymptomsO Discomfort or pain in the testicle, or a feeling of heaviness in

the scrotumO Pain in the back or lower abdomen

O Ovarian CancerO Causes

O Family HistoryO Age (occurs more in women over 65 years old)

O Symptoms: not all due to cancerO Pressure/pain in abdomen, pelvis, back, legsO Nausea, indigestion, gas, constipation, or diarrhea

Klinefelter SyndromeO Causes

O Having one extra X chromosome

O SymptomsO Abnormal body proportions (long legs, short

trunk, shoulder equal to hip size)O Abnormally large breasts O InfertilityO Sexual problemsO Less than normal amount of pubic, armpit,

and facial hairO Small, firm testicles

Interesting FactsO The survival rate of testicular cancer patients in

the early stage is 95%O Testicular cancer is the most common form of

cancer in men between the ages of 15 and O Klinefelter syndrome also increases your risk of:

O ADHDO Breast cancer O Learning disabilities (ex. Dyslexia) O Depression
