Saccular aneurysms, also known as berry aneurysms, appear as a round outpouching and are the most common form of cerebral aneurysm.

A further complication in the case of the alveolar glands may occur in the form of still smaller saccular diverticuli growing out from the main sacculi.

Stacconi and Romani ( 2011 ) found that, overall, the saccular structure within the spermatheca plays a key role in identifying mated and unmated females.

Even more curious, Todd says, our saccular frequency sensitivity appears to mimic that of fish _ the only type of creature known to use its sacculus for hearing.

Moreover, he wrote : 4 books on epidermoids ( 1957 ), Cranio cerebral topography ( 1959 ), Acoustic neuromas ( 1970 ) and Ruptured saccular aneurysms ( 1987 ).

Saccular aneurysms tend to have a lack of tunica media and elastic lamina around its dilated location ( congenital ), with wall of sac made up of thickened hyalinized intima and adventitia.
17.
Saccular aneurysms are spherical in shape and involve only a portion of the vessel wall; they vary in size from 5 to in diameter, and are often filled, either partially or fully, by a thrombus.

Other factors are positively associated with the regression of aneurysms, including being younger than a year old at the onset of Kawasaki disease, fusiform rather than saccular aneurysm morphology, and an aneurysm location in a distal coronary segment.
19.
Tilts of the head off the horizontal plane and translational movements of the head in any direction stimulate a distinct subset of hair cells in the saccular and utricular maculae, while simultaneously suppressing responses of other hair cells in these organs.
20.
Rupture risk is also related to shape; so-called " fusiform " ( long ) aneurysms are considered less rupture prone than " saccular " ( shorter, bulbous ) aneurysms, the latter having more wall tension in a particular location in the aneurysm wall.
