Moll's gland, also known as the gland of Moll or ciliary gland, is a modified apocrine sweat gland that is found on the margin of the eyelid. They are next to the base of the eyelashes , and anterior to the meibomian glands within the distal eyelid margin.
Glands of Zeis are unilobar sebaceous glands located on the margin of the eyelid.The glands of Zeis service the eyelash.These glands produce an oily substance that is issued through the excretory ducts of the sebaceous lobule into the middle portion of the hair follicle.
A megaannus (Ma) represents one million (10 6) years. The geologic time scale or geological time scale ( GTS ) is a representation of time based on the rock record of Earth . It is a system of chronological dating that uses chronostratigraphy (the process of relating strata to time) and geochronology (a scientific branch of geology that aims to ...
The ice core spans at least 1.2 million years of Earth’s climate history.
Hidrocystoma (also known as cystadenoma, [1] a Moll's gland cyst, [1] and a sudoriferous cyst [1]) is an adenoma of the sweat glands. [2]: 787 Hidrocystomas are cysts of sweat ducts, usually on the eyelids. [3]: 664 They are not tumours (a similar-sounding lesion called hidroadenoma is a benign tumour).
The geologic temperature record are changes in Earth's environment as determined from geologic evidence on multi-million to billion (10 9) year time scales. The study of past temperatures provides an important paleoenvironmental insight because it is a component of the climate and oceanography of the time.
The authors therefore think the moon formed around 4.51 billion years ago — more than 100 million years earlier than the commonly accepted estimate.
The oldest dinosaur-bearing fossil assemblage, the Ischigualasto Formation of Argentina, has been radiometrically dated back to 230.3 to 231.4 million years ago. This age is very similar to the minimum age calculated for the CPE (≈230.9 million years ago).
