Parts of the cartridge:

There are 5 types of Cartridges:
Rimmed
Semi-Rimmed
Rimless
Belted
Rebated

Parts of the Cartridge Case Case_h10

Rimmed Case : A rimmed case is distinguished by a rim that extends outward from the head of the case, to a diameter noticeably larger than the case body. (44 magnum, 303 British, 38 special, 357 magnum, ect.)

Semi-Rimmed : Semi-rimmed design is a rim only slightly larger than the case body itself. (.25 ACP, .38 Super)

Rimless : Despite the “rimless” designation, the case does indeed have a rim to facilitate extraction. In this design, however, the rim does not extend beyond the case body. Rather, the rim diameter is approximately equal to the diameter of the case body itself just ahead of the extractor groove. (.30-06, .270, .308 ect)

Belted : The defining characteristic of these cartridges is a small band, or belt, around the head of the case, just ahead of the extractor groove. In use, the belt acts in exactly the same manner as a rim. Originally, this was an absolute necessity, owing to the steeply sloping shoulders of many of the first belted cases. (.7mm Remington Magnum, .300 Winchester, .375 H&H Magnum)

Rebated : the rebated case is characterized by a rim that is noticeably smaller in diameter than the case body. The intent of this design is normally to offer increased case capacity without altering or enlarging an existing bolt face. (.41 AE, 50 Beowulf)

I looked at the link you pointed to and maybe it would be better to call this "Parts of a cartridge case" instead of "Parts of a cartridge". A cartridge has a bullet and a primer and powder.
