diaphragm
Chest cavity floor
A diaphragm is a thin partition separating two spaces.
The anatomical diaphragm is the dome-shaped muscle beneath the lungs that contracts during breathing—when you laugh uncontrollably or get hiccups, it's your diaphragm spasming.
In optics and photography, a diaphragm is an adjustable aperture controlling how much light enters a lens.
A contraceptive diaphragm is a flexible cup inserted to cover the cervix during intercourse.
