The spinal cord is a long, thin, tubular structure made up of nervous tissue that extends from the medulla oblongata in the lower brainstem to the lumbar region of the vertebral column (backbone) of vertebrate animals. The center of the spinal cord is hollow and contains a structure called the central canal, which contains cerebrospinal fluid.
Spinal precautions. Spinal precautions, also known as spinal immobilization and spinal motion restriction, are efforts to prevent movement of the spine in those with a risk of a spine injury. [1] This is done as an effort to prevent injury to the spinal cord. [1] It is estimated that 2% of people with blunt trauma will have a spine injury.
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.
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.
The grey columns are three regions of the somewhat ridge-shaped mass of grey matter in the spinal cord. [1] These regions present as three columns: the anterior grey column, the posterior grey column, and the lateral grey column, all of which are visible in cross-section of the spinal cord. The anterior grey column is made up of alpha motor ...
The brain is the central organ of the human nervous system, and with the spinal cord makes up the central nervous system. The brain consists of the cerebrum, the brainstem and the cerebellum. It controls most of the activities of the body, processing, integrating, and coordinating the information it receives from the sense organs, and making ...
Meninges. 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 ...
Lumbar puncture (LP), also known as a spinal tap, is a medical procedure in which a needle is inserted into the spinal canal, most commonly to collect cerebrospinal fluid (CSF) for diagnostic testing. The main reason for a lumbar puncture is to help diagnose diseases of the central nervous system, including the brain and spine.
