Parenchyma is the tissue made up of cells and intercellular spaces that fills the interior of the body of a flatworm, which is an acoelomate. This is a spongy tissue also known as a mesenchymal tissue, in which several types of cells are lodged in their extracellular matrices.

Anatomy The tissue characteristic of an organ, as distinguished from associated connective or supporting tissues. 2. Botany A simple plant tissue, composed of thin-walled cells and forming the greater part of leaves, roots, the pulp of fruit, and the pith of stems. pa·ren′chy·mal, par′en·chym′a·tous (păr′ĕn-kĭm′ə-təs) adj.

May 26, 2017 · Parenchyma is a term used to describe the functional tissues in plants and animals. This tissue is “functional” – performing tasks such as photosynthesis in plants or storing information in the human brain – as opposed to “structural” tissues like wood in …

Jun 16, 2022 · Animal parenchyma: In anatomy, the parenchyma refers to the essential component of an organ. It is used to designate the functional elements of an organ, as distinguished from its framework or stroma. For example, the parenchyma of the brain includes neurons and glial cells.

The parenchyma is the gas-exchanging tissue of the lung and has a surface area roughly comparable to that of a tennis court. Blood is distributed to the lung through the branching pulmonary artery, which subdivides with…

Nov 2, 2023 · The brain parenchyma is the essential functional tissue of the brain, consisting of gray matter and white matter. Imaging techniques like MRI, CT scans, PET scans, fMRI, are tools for studying brain parenchyma, allowing us to better understand its structure and function.

Jul 29, 2022 · Parenchyma / Stroma. The parenchyma of an organ consists of that tissue which conducts the specific function of the organ. An organ's parenchyma usually comprises the bulk of the organ. Stroma is everything else -- connective tissue, blood vessels, nerves, ducts.

Objective: To visualize the cell type called parenchyma, as an assemblage of various living, mature cells. Parenchyma cells are diverse. The sizes, shapes, contents, walls, and functions of parenchyma cells vary. One factor to consider when addressing “parenchyma” is its developmental changes.

The lymph node parenchyma is surrounded and divided by a fibrous capsule with attached septa. The parenchyma is composed of the cortex, medulla and paracortex. B cells predominate in the cortex and medulla whereas T cells are mainly found in the paracortical tissues.

Sep 28, 2013 · In anatomy, parenchyma refers to the functional part of an organ in the body. This is in contrast to the stroma or interstitium, which refers to the structural tissue of organs, such as the connective tissues. Embryologically, the majority of organ parenchyma develops from the ectoderm or endoderm, rather than mesoderm: ectoderm: brain, skin
