This is critical because the brain lacks a true lymphatic system. In the remainder of the body, small amounts of protein are able to leak from the parenchymal capillaries through the lymphatic system. In the brain, this ends up in the interstitial space. The protein portions are able to leave through the very permeable pia mater and enter the ...
Laying the whole-mount on a glass slide allows for histological analysis of the entire dura, including the superior sagittal and transverse sinuses. Human meningeal lymphatic vessels using magnetic resonance imaging (MRI) with gadobutrol as constrast agent which in the dura mater leaks out of blood vessels and collects inside lymphatic vessels ...
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]

Hence, what is technically a transverse (orthogonal) section with respect to the body length axis of a rat (dividing anterior from posterior) may often be referred to in rat neuroanatomical coordinates as a coronal section, and likewise a coronal section with respect to the body (i.e. dividing ventral from dorsal) in a rat brain is referred to ...
The glia limitans, or the glial limiting membrane, is a thin barrier of astrocyte foot processes associated with the parenchymal basal lamina surrounding the brain and spinal cord. It is the outermost layer of neural tissue , and among its responsibilities is the prevention of the over-migration of neurons and neuroglia , the supporting cells ...
The name dura mater derives from the Latin for tough mother (or hard mother), [15] a loan translation of Arabic أم الدماغ الصفيقة (umm al-dimāgh al-ṣafīqah), literally 'thick mother of the brain', matrix of the brain, [16] [17] and is also referred to by the term "pachymeninx" (plural "pachymeninges").
Horizontal sections are orthogonal to both transverse and sagittal sections, and in theory, are parallel to the length axis. Due to the axial bend in the brain (forebrain), true horizontal sections in that region are orthogonal to coronal (transverse) sections (as is the horizon relative to the face).
