thoracic segments - BrainInfo

thoracic segments (SPCth)

The term thoracic segments (SPCth) refers to the 9th to 20th segments in the middle of the spinal cord (SPC). Located between the cervical segments (SPCcv) and the lumbar segments (SPClb) they are labeled T1 to T12 ( Carpenter-1983 ). They are defined by histology and are found in all vertebrates ( Swanson-2015 ). Final 24 Dec 2024 ).

Also known as: Pars thoracica, Segmenta thoracica, thoracic segments, thoracic segments of spinal cord, thoracic 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 ).
