In biology, a lumen (plural lumina) is the inside space of a tubular structure, such as an artery or intestine. It comes from Latin lumen ‘an opening’. It can refer to: The interior of a vessel, such as the central space in an artery, vein or capillary through which blood …

When refering to a cell where is the lumen?
· A lumen (Lat. lūmen, an opening or light) (pl. lumina) in biology is the inside space of a tubular structure, such as an artery or intestine. By extension, a lumen can also be the inside space of a cellular component or structure, such as the endoplasmic reticulum.
BIOL 101 Introductory Biology – OE
Lumen OER courses apply learning science to engage students and better support the learning process. Lumen materials aim to deliver an active learning experience. They include text, images, videos, assessments, directed feedback, practice questions, simulations, and other interactives that invite students to apply their knowledge, improve their understanding, and perform better.
Endoplasmic reticulum lumen
The lumen of the endoplasmic reticulum (ER) is the area enclosed by the endoplasmic reticulum membrane, an extensive network of membrane tubules, vesicles and flattened cisternae (sac-like structures) found throughout the eukaryotic cell, especially those
The thylakoid lumen is a continuous aqueous phase enclosed by the thylakoid membrane. It plays an important role for photophosphorylation during photosynthesis . During the light-dependent reaction, protons are pumped across the thylakoid membrane into the lumen making it acidic down to pH 4.

The endoplasmic reticulum (ER) is, in essence, the transportation system of the eukaryotic cell, and has many other important functions such as protein folding. It is a type of organelle made up of two subunits – rough endoplasmic reticulum (RER), and smooth endoplasmic reticulum (SER). The endoplasmic reticulum is found in most eukaryotic
What is a Double Lumen Catheter? (with pictures)
· One lumen allows saline to fill a small balloon at the lumen’s tip, inside the bladder, to hold the catheter in place. The other lumen carries urine out of the bladder. Urinary catheter use carries a high risk of catheter infection, so catheters with antibiotic agents either coating the surface or infused in the flexible material are often used in the urinary tract.
Lumen Formation Is an Intrinsic Property of Isolated …
Since lumen formation is an indispensable step in early mammalian development, this system can provide a powerful model for investigation of this process in a controlled environment. Overall, our data establish that lumenogenesis is a fundamental cell biological property of human PSCs.

Understanding the roles of the thylakoid lumen in …
Interestingly, while the thylakoid lumen proteome of at least 80 proteins contains several large protein families, individual members of many protein families have highly divergent roles. This is indicative of evolutionary pressure leading to neofunctionalization of lumenal proteins, emphasizing the important role of the thylakoid lumen for photosynthetic electron transfer and ultimately for

Definition of Lumen
Lumen: A luminous term referring to the channel within a tube such as a blood vessel or to the cavity within a hollow organ such as the intestine. Lumen is a luminous term because it is Latin for light, including the light that comes through a window. When a hollow
Other articles where Photosystem I is discussed: bacteria: Phototrophic metabolism: The photosystem in green bacteria is related to photosystem I of higher plants, whereas that in purple bacteria is related to photosystem II, which provides some indication of an evolutionary trail from bacteria to plants (see photosynthesis: The process of photosynthesis: the light reactions).
