Intervertebral Joints

By Dr. Joseph H Volker | 2018-08-30T09:45:48+00:00 August 8th, 2018|Anatomy, Back, Joints and Ligaments|0 Comments

The Intervertebral Joints are created: Between the bodies of the vertebrae Between the articular processes of the vertebra Joints Between The Bodies Of The Vertebrae Thin plates of hyaline cartilages cover the inferior and superior surfaces of the adjacent vertebral bodies, which then are linked by fibrocartilaginous intervertebral disc. An outer rim by [...]

Vertebral Foramen

By Dr. Joseph H Volker | 2018-08-30T11:07:19+00:00 August 8th, 2018|Anatomy, Area, Back|0 Comments

The anterior section known as the body and the posterior section known as the vertebral arch create an opening or foramen known as vertebral foramen which is found within a normal vertebra. The spinal cord and its meninges are contained within the vertebral foramen. Together, the vertebral canal is created by the vertebral foramina of [...]

Tracts of the Spinal Cord

By Dr. Joseph H Volker | 2018-08-30T11:12:26+00:00 August 8th, 2018|Anatomy, Area, Back|0 Comments

The tracts are referred to as after the names of masses of grey matter joined by them. Their names normally contain 2 parts (or terms), the very first term indicates the origin and second the conclusion of the tract. As an example, a tract originating in cerebral cortex and ending in the spinal cord is [...]

By Dr. Joseph H Volker | 2018-08-30T10:10:15+00:00 August 8th, 2018|Anatomy, Back, Nerves|0 Comments

31 pairs of spinal nerves are found in the human body. All spinal nerves originate from a ventral root as well as a dorsal root. The combination of many dorsal as well as ventral root filaments or rootlets forms each root. All spinal nerve almost directly split up within a large ventral ramus as well [...]

Thoracolumbar Fascia

By Dr. Joseph H Volker | 2018-08-30T09:00:28+00:00 August 8th, 2018|Anatomy, Back|0 Comments

Thoracolumbar Fascia is the deep fascia on the rear of the trunk. It does the work of binding the vertebral column to the posterolateral surfaces of the vertebral bodies. The thoracolumbar fascia is divided into 2 parts: Lumbar part of thoracolumbar fascia Thoracic part of thoracolumbar fascia Lumbar Part of Thoracolumbar Fascia The [...]

Spinal Cord

By Dr. Joseph H Volker | 2018-09-12T08:47:54+00:00 August 8th, 2018|Anatomy, Back, Nerves|0 Comments

The spinal cord is the lower cylindrical part of the central nervous system inhabiting the upper two-thirds of the vertebral canal and is typically 45 cm long. It starts at the foramen magnum as the continuance of medulla oblongata and normally ends opposite the intervertebral disc between the L1 and L2 vertebrae. The spinal cord [...]

Dural Sac/ Thecal Sac

By Dr. Joseph H Volker | 2018-08-30T10:23:07+00:00 August 8th, 2018|Anatomy, Area, Areas, Back, Pelvis|0 Comments

The Dural SAC is the protective membrane of the spinal canal that encloses it and is located all-over spinal cord. The cerebral spinal fluid is also enclosed inside it, which is vital and helps in maintaining a fully functioning spine. It contains the spinal cord and within the lumbar spine, the cauda equina and shields [...]

Vertebral Canal/Spinal Canal

By Dr. Joseph H Volker | 2018-08-30T09:49:05+00:00 August 8th, 2018|Anatomy, Area, Back|0 Comments

Within the vertebral column, there is an extended cavity called the vertebral canal. When the vertebrae are set together within the vertebral column, the entire series of vertebral foramina stacked one over another is called Vertebral canal or Spinal canal. This canal houses the Spinal cord along with meninges and epidural space. Vertebral Canal [...]
