Spinal anaesthesia (or spinal anesthesia), also called spinal block, subarachnoid block, intradural blockand intrathecal block,[1] is a form of regional anaesthesia involving the injection of a local anaesthetic into the subarachnoid space, generally through a fine needle, usually 9 cm (3.5 in) long. For obese patients longer needles are available (12.7 cm / 5 inches). The tip of the spinal needle has a point or small bevel. Recently, pencil point needles have been made available (Whitacre, Sprotte, Gertie Marx and others)
Physiology is the study of the function of body parts and the body as a whole. Some specializations within each of these sciences follow: Gross (macroscopic) anatomy is the study of body parts visible to the naked eye, such as the heart or bones.
The spinal cord is a long, thin, tubular bundle of nervous tissue and support cells that extends from the medulla oblongata in the brainstem to the lumbar region of the vertebral column. The brain and spinal cordtogether make up the central nervous system (CNS).
