ventromedial half of each somite that forms the vertebral body and intervertebral disc. (More? Musculoskeletal Notes | Week 3 Notes)
a zone of the skeleton supplied by an individual spinal sensory nerve, and represents a basic unit of vertebral embryonic development
Historical depiction, via a body map, indicating regions of the body that are supplied by a spinal nerve, presumably corresponding to an area of pain or symptomatology.
Area of the bone or joint or periosteum innervated by a single spinal segment.
The somites split into three segments, the most medial of which is the sclerotome. This mesoderm is fated to become vertebral structures.
A sclerotome is part of a somite, a structure in vertebrate embryonic development. Sclerotomes eventually differentiate into the vertebrae and most of the skull. The caudal half of one sclerotome fuses with the cranial half of the adjacent one to form each vertebra.
