lumbar segments - BrainInfo

lumbar segments (SPClb)

The term lumbar segments (SPClb) refers to the 20th to 24th segments in the middle of the spinal cord (SPC). Located between the thoracic segments (SPCth) and the sacral segments (SPCsc) they are labeled L1 to L5 in the human. These segments have massive anterior gray columns and posterior gray columns, are nearly circular in horizontal sections and give rise to the corresponding lumbar nerves ( Carpenter-1983 ). Defined by dissection, they are found in all vertebrates ( Swanson-2015 ). Final 24 Dec 2024.

Also known as: lumbar segments, lumbar segments of spinal cord, Pars lumbalis, Segmenta lumbalia, lumbar part of spinal cord

Models Where It Appears

Classical Vertebrate Central Nervous System

The Classical Vertebrate Central Nervous System is a hierarchical model of gray matter structures that are common to the brain and spinal cord of all vertebrates. As in other classical models, structures are grouped by proximity as observed on dissection, and the upper levels correspond roughly to their organization in the embryo. The hierarchical organization is based on the Basic Partts List for Adult Nervous System in All Animals ( Swanson-2104 ), the nomenclature on NeuroNames ( Bowden-2012 ).

spinal cord

cervical segments (cervical part of spinal cord)

thoracic segments (thoracic part of spinal cord)

lumbar segments (lumbar part of spinal cord)
