Trabecula
A trabecula (plural trabeculae, from Latin for "small beam") is a small, often microscopic, tissue element in the form of a small beam, strut or rod, generally having a mechanical function, and usually composed of dense collagenous tissue (such as the trabecula of the spleen.) They can be composed of other materials; in the heart, for example, muscles such as trabeculae carneae and septomarginal trabecula form similar structures. The formation of trabeculae is known as trabeculation.
On histological section, trabeculae of a cancellous bone can look like septa, but in three dimensions they are topologically distinct, with trabeculae being roughly rod or pillar-shaped and septa being sheet-like.
When crossing fluid-filled spaces, trabeculae may have the function of resisting tension (as in the penis, see for example trabeculae of corpora cavernosa and trabeculae of corpus spongiosum) or providing a cell filter (as in the trabecular meshwork of the eye.)
Multiple perforations in a septum may reduce it to a collection of trabeculae, as happens to the walls of some of the pulmonary alveoli in emphysema.
Trabecula (gastropod)
Trabecula is a genus of very small sea snails, marine gastropod molluscs or micromolluscs in the family Pyramidellidae, the pyrams and their allies, and the subfamily Chrysallidinae, a large taxon of minute marine gastropods with an intorted protoconch.
Taxonomy
Dall & Bartsch (1904: 10) misinterpreted this genus and described it with “intercostal spaces crossed by equally spaced, raised spiral threads, sculpture reticulated”, despite that Monterosato (1884) wrote that there is no apparent spiral sculpture. This may explain why Dall & Bartsch (1909) described a new genus Salassiella with a type species extremely similar to that of Trabecula
General description
The whorls of the teleoconch are rounded, and longitudinally lamellose. The aperture is semicircular, with an exterior rib. There is no apparent spiral sculpture. The apex is retrorse. The columella lacks a fold or tooth.

Tropicalia
by: BeckOh, when they beat upon a broken guitar
And all the streets, they reek of tropical charms
The embassies lie in hideous shards
Where tourists snore and decay
When they dance in a reptile blaze
You wear a mask, an equatorial haze
Into the past, a colonial maze
Where there's no more confetti to throw
You wouldn't know what to say to yourself
Love is a poverty you couldn't sell
Misery waits in vague hotels
To be evicted
You're out of luck, you're singing funeral songs
To the studs, they're anabolic and bronze
They seem to strut in their millennial fogs
'Til they fall down and deflate
You wouldn't know what to say to yourself
Love is a poverty you couldn't sell
Misery waits in vague hotels
To be evicted
Oh, and now, you've had your fun
Under an air-conditioned sun
It's burned into your eyes
Leaves you plain and left behind
I'll see them rise and fall
Into the jaws of a pestilent love
You wouldn't know what to say to yourself
Love is a poverty you couldn't sell
Misery waits in vague hotels
