controls pituitary gland
Neurons in hypothalumus produce ADH (antidiuretic hormone) and oxytocin
Hypothalamus-controls pituitary by producing hypothalamic-realising hormoes and hypothalimic-inhibiting hormones
1. Thyroid Stimulating Hormone (TSH)
2. Adrenocorticopic hormone (ACTH)
Hands, Feet, and Facial bones is where one will grow more.

Once mature stored in the vas deferens and empties into ejaculatory duct, wich enteres the urethra. Sperm leaves the penis in a fluid called semen. Can't survive in female genital tract for more than 48 hrs.
Head- contains nuceus and is covered by the acrosome.
Acrosome- enzyme Cap that penitrates egg during fertilization.
Middle- Contains mitochondria for energy so sperm can swim.
Tail- for movement is called flagella.
Male organ of sexual intercorse
tip is covered with foreskin
Circumcision- removal of foreskin

Testieses-epididymis-vas deferens-ejaculatory duct---urethra--- out of penis
Urethra carries urine and semen but not at the same time.

Towards the end ppl will develop non life threatning sicknesses. but they are reoccuring. EX. Thrush, Herpes Simplex I.
Full blown AIDS
T-lympocites are below 200. Very think and weak. Everything put in body has side effects.
Caused by protizoens
In AIDS patients loss of brain cells, seisores, and weakness
Caused by herpes simplex virus
Type-1 causes cold sores & Fever blisters
Type 2-causee genital herpes
1st sympt- Itching & tingleing at infected site Blisters form and rupture leaving ulsers and fever. Solen lymphnodes, pain upon urination. Sunlight, stress, menstration, and sex can cause all symptoms to occure.
