Study Notes

Deep Muscles of the Back

The deep muscles of the back include the intrinsic muscles, which are divided into two groups: intermediate deep (erector spinae group) and deep deep (transversospinales group)
These muscles extend from the base of the cranium to the sacrum and are associated with movements of the spinal column and control of posture

Spinal Column

The spinal column consists of vertebrae, which are divided into cervical, thoracic, and lumbar regions
Each vertebra has a specific structure, including a vertebral body, pedicle, transverse process, spinous process, and vertebral arch

Spinal Cord

The spinal cord is a long, thin, tube-like structure that extends from the base of the brain down to the lower back
It is divided into grey matter and white matter
Grey matter is found on the inside of the spinal cord and contains sensory and motor neurons
White matter is found on the outside of the spinal cord and contains nerve fibres

Internal Structure of Spinal Cord

The spinal cord has a posterior median sulcus and a central canal that is continuous with the ventricular system
The grey matter is divided into horns, including the dorsal horn, ventral horn, and lateral horn
The dorsal horn contains sensory nuclei, and the ventral horn contains motor neurons
The lateral horn is found in the thoracic region and contains sympathetic neurons

Ligaments of the Vertebral Column

There are seven key ligaments of the vertebral column, including the anterior longitudinal ligament, posterior longitudinal ligament, ligamentum flavum, interspinous ligament, supraspinous ligament, and intertransverse ligament
These ligaments provide stability and support to the vertebral column

Muscles of the Back

The muscles of the back include the deep muscles, which are divided into the erector spinae group and the transversospinales group
The erector spinae group includes the iliocostalis, longissimus, and spinalis muscles
The transversospinales group includes the semispinalis, multifidus, and rotatores muscles
