lingula

If one is lying on the left, it goes to the lingula.

Modern species of Lingula are very similar from their fossil ancestors.

About the fourth month a center appears for each lingula and speedily joins the rest of the bone.

There are two bronchopulmonary segments of the lingula: Superior and inferior.

Some sources define the lingula as a distinct lobe.

Living fossils may occur regularly in the fossil record, such as the lampshell Lingula.

Darwin expected species to change slowly, but not at the same rate - some organisms such as Lingula were unchanged since the earliest fossils.

There is no metamorphosis in Lingula.

The lingula receives information from the contralateral inferior retina representing the superior visual field.

It includes the Lingula, Discina, and allied forms.

(There is no middle lobe on the left lung, though there is a lingula.)

The sphenomandibular ligament runs from the spine of the sphenoid bone to the lingula of mandible.

This also contains the lingula, a triangular piece of bone that overlies the mandibular foramen antero-medially.

The specific epithet lingulata is derived from the Latin word lingula, meaning "small tongue", and refers to this unique morphological feature.

However, the term lingula is used to denote a projection of the upper lobe of the left lung that serves as the homologue.

The right middle lobe and left lingula of the lungs are served by bronchi that are oriented downward when a person is in the upright position.

The genus Lingula (Bruguiere, 1797) is the oldest known animal genus that still contains extant species.

The lingula is a small tongue-shaped process, consisting of four or five folia; it lies in front of the lobulus centralis, and is concealed by it.

There are also fossils of Lepidodendron, Stigmaria, Carbonicola, Dunbarella and Lingula: all found in the Baildon Moor area.

It is thought that the lingula of the left lobe is the remnant of the middle lobe of the left lung, which has been lost through evolution.

Along the posterior part of the lateral margin of this groove, in the angle between the body and greater wing, is a ridge of bone, called the sphenoidal lingula.

A relationship between annelids and brachiopods may be difficult to reconcile with data from haemerythrin sequences that indicate a close relationship between priapulids and the inarticulate brachiopod Lingula.

Thus it is used to refer to the peak of the fourth ventricle.; closely related to the posterolateral fissure, which divide the lingula from the nodulus of the cerebelar vermis.

The descendants of Lingulella, slightly larger and called Lingula, are found today in, among other places, the coastal waters of Japan, burrowing in the sand and mud of estuaries.

This creature was the nautilus and we can get an accurate idea of how it and its family lived for one species was destined, like Lingula and Neopilina, to become a living fossil.
