Lung parenchyma showing damage due to large subpleural bullae. Parenchyma (/ p ə ˈ r ɛ ŋ k ɪ m ə /) [1] [2] is the bulk of functional substance in an animal organ or structure such as a tumour. In zoology, it is the tissue that fills the interior of flatworms. In botany, it is some layers in the cross-section of the leaf. [3]
Information about the structure and function of the human brain comes from a variety of experimental methods, including animals and humans. Information about brain trauma and stroke has provided information about the function of parts of the brain and the effects of brain damage. Neuroimaging is used to visualise the brain and record brain ...
In a multicellular organism, an organ is a collection of tissues joined in a structural unit to serve a common function. [1] In the hierarchy of life, an organ lies between tissue and an organ system. Tissues are formed from same type cells to act together in a function. Tissues of different types combine to form an organ which has a specific ...
Cerebrospinal fluid (CSF) is a clear, colorless transcellular body fluid found within the meningeal tissue that surrounds the vertebrate brain and spinal cord, and in the ventricles of the brain. CSF is mostly produced by specialized ependymal cells in the choroid plexuses of the ventricles of the brain, and absorbed in the arachnoid granulations .
Human subventricular zone. From a paper by Oscar Arias-Carrión, 2008 In an embryonic rat brain, GAD67-binding marker tends to concentrate in subventricular zone. An image from Popp et al., 2009. [1] The subventricular zone (SVZ) is a region situated on the outside wall of each lateral ventricle of the vertebrate brain. [2]
The cells of the body's surface form the outer layer of skin. Inside the body, epithelial cells form the lining of the mouth and alimentary canal and protect these organs. Epithelial tissues help in the elimination of waste. Epithelial tissues secrete enzymes and/or hormones in the form of glands. Some epithelial tissue perform secretory functions.
Intraparenchymal hemorrhage is one form of intracerebral bleeding in which there is bleeding within brain parenchyma. The other form is intraventricular hemorrhage). [1] Intraparenchymal hemorrhage accounts for approximately 8-13% of all strokes and results from a wide spectrum of disorders.
The astrocytes of the glia limitans are responsible for separating the brain into two primary compartments. The first compartment is the immune-privileged brain and spinal cord parenchyma. This compartment contains multiple immunosuppressive cell surface proteins such as CD200 and CD95L and it allows for the release of anti-inflammatory factors.
