Vertebral Cross Section

The spinal cord is elliptical in cross section being compressed dorsolaterally.

Vertebral cross section. This area is made up of all the nerve fibers that direct the reflex actions and convey the impulses that go back and forth to the brain. Cross section of the spinal cord if a person were to take a slice of the spinal cord horizontally they would see a circular area in the middle covered in protective layers the meninges. Spinal cord cross section the spinal cord which consists of the major nerve tract of vertebrates runs down from the bottom of the brain through the passageway of the spinal column.

Using multiplanar imaging techniques measures of vertebral cross sectional area vertebral height and intervertebral disc height in the lumbar spine were obtained in 35 pairs of girls and 11 pairs of boys with and without adolescent idiopathic scoliosis of the thoracic spine matched for age height and weight. Understand all things spinal cord white and grey matter with this step by step interactive quiz and worksheet guide. In cross section c s the segments appear to be divided into two zones.

The gray matter is made up of neuroglia cells and neuron cell bodies. The outer zone contains many myelinated axons that run up and down the spinal cord. A healthy spine has strong muscles and bones flexible joints ligaments and tendons and sensitive nerves.

The spinal cord in cross section has a central region of darkergray matterand the rest is lighter white matter. Two prominent grooves or sulci run along its length. The white matter is made up of neuron axons mostly but not all myelinated.
