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)

Acrosome- enzyme Cap that penitrates egg during fertilization.
Middle- Contains mitochondria for energy so sperm can swim.
Tail- for movement is called flagella.

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
