In anatomy, the meninges (/ məˈnɪndʒiːz /, [1][2] sg.: meninx (/ ˈmiːnɪŋks / or / ˈmɛnɪŋks / [3]), from Ancient Greek μῆνιγξ (mēninx) 'membrane' [4]) are the three membranes that envelop the brain and spinal cord. In mammals, the meninges are the dura mater, the arachnoid mater, and the pia mater. Cerebrospinal fluid is ...
Pia mater (/ ˈpaɪ.ə ˈmeɪtər / or / ˈpiːə ˈmɑːtər /), [1] often referred to as simply the pia, is the delicate innermost layer of the meninges, the membranes surrounding the brain and spinal cord. Pia mater is medieval Latin meaning "tender mother". [1] The other two meningeal membranes are the dura mater and the arachnoid mater.
Dura mater. In neuroanatomy, dura mater is a thick membrane made of dense irregular connective tissue that surrounds the brain and spinal cord. It is the outermost of the three layers of membrane called the meninges that protect the central nervous system. The other two meningeal layers are the arachnoid mater and the pia mater.
The meningeal lymphatic system is composed of a network of vessels along the dural sinus in the dura which express lymphatic endothelial cell marker proteins, including PROX1, LYVE1, and PDPN. The vessels extend along the length of both the superior sagittal and transverse sinuses and directly connects to the deep cervical lymph nodes. [1]
Anatomical terminology. [ edit on Wikidata] The subarachnoid cisterns are spaces formed by openings in the subarachnoid space, an anatomic space in the meninges of the brain. [ 1 ] The space is situated between the two meninges, the arachnoid mater and the pia mater. These cisterns are filled with cerebrospinal fluid (CSF).
Anatomical terms of neuroanatomy. [edit on Wikidata] The arachnoid mater (or simply arachnoid) is one of the three meninges, the protective membranes that cover the brain and spinal cord. It is so named because of its resemblance to a spider web. The arachnoid mater is a derivative of the neural crest mesoectoderm in the embryo.
The skeletal section of the head and neck forms the top part of the axial skeleton and is made up of the skull, hyoid bone, auditory ossicles, and cervical spine. The skull can be further subdivided into: the cranium (8 bones: frontal, 2-parietal, occipital, 2-temporal, sphenoid, ethmoid), and. the facial bones (14 bones: 2-zygomatic, 2 ...
In neuroanatomy, the ventricular system is a set of four interconnected cavities known as cerebral ventricles in the brain. [1][2] Within each ventricle is a region of choroid plexus which produces the circulating cerebrospinal fluid (CSF). The ventricular system is continuous with the central canal of the spinal cord from the fourth ventricle ...
