Sorry, no etymologies found.
Its posterior part (the so-called saccular lung) has unique thick, muscular walls* that allows stored air to be forced forward into the functional anterior part (termed the bronchial lung) and the anterior projection of the lung (the so-called tracheal lung) is large and extends well forwards relative to that of terrestrial snakes.
* Normally in snakes, the posterior lung walls are thin and sac-like, hence the name ‘saccular lung’.
If these glands have the general form of tubes, they are called _tubular_ glands; if sac-like in shape, they are called _saccular_ glands.
The larger of the compound saccular glands are also called _racemose_ glands, on account of their having the general form of a cluster, or raceme, similar to that of a bunch of grapes.
Both the tubular and the saccular glands may, by branching, form a great number of similar divisions which are connected with one another, and which communicate by a common opening with the place where the secretion is used.
How do tubular glands differ in structure from saccular glands?
In those aneurysms which are a _saccular_ bulging on one side of the artery the blood may be induced to coagulate, or may of itself deposit layer upon layer of pale clot, until the sac is obliterated.
Where the dilatation is of the saccular variety, it may come up in such quantities and with so much suddenness as to gush from the mouth.
It used to be considered a disease of middle age, but of late years Dr Walter Carr has shown that the condition is a fairly common one among debilitated children after measles, whooping cough, &c. The dilatation is commonly cylindrical, more rarely saccular, and it is the medium and smaller sized tubes that are generally affected, except where the cause is mechanical.
THE SEBACEOUS GLANDS are small saccular glands with their ducts opening into the mouths of the hair follicles.
