Sectional Anatomy Of The Spinal Cord

Contains 2 types of nervous tissue. Tracts are named with their point of origin first.

The gray matte of the spinal cord is located at its center with the white matter surrounding it.

Sectional anatomy of the spinal cord. The peripheral white matter contains the axon tracts. It is situated inside the vertebral canal of the vertebral column. Gross anatomy the spinal cord is part of the central nervous system cns which extends caudally and is protected by the bony structures of the vertebral column.

Describe the cross sectional anatomy of the spinal cord. Spinal cord segments cross sectional anatomy. Cross sectional anatomy of the spinal cord.

The ventral anterior median fissure and the more shallow dorsal posterior median sulcus. It passes through the spinal canal or spinal cavity of the vertebral column ie the backbone or spine. A cross sectional view of the spinal cord demonstrates a central butterfly shaped area of gray matter and peripheral white matter fig.

The posterior median sulcus is the groove in the dorsal side and the anterior median fissure is the groove in the ventral side. The spinal cord is part of the central nervous system cns. It contains the somas dendrites and proximal parts of the axons of neurons.

Cross sectional anatomy of spinal cord. An interactive quiz covering spinal cord cross sectional anatomy through multiple choice questions and featuring the iconic gbs illustrations. Two prominent grooves or sulci run along its length.

The spinal cord like the brain consists of two kinds of nervous tissue called gray and white matter. These two grooves run the length of the cord and partially divide it into right and left halves. Gray matter has a relatively dull color because it contains little myelin.

The spinal cord is elliptical in cross section being compressed dorsolaterally. Almost dividing the spinal cord in half are two longitudinal grooves. Spinal cord anatomy basically spinal cord is a long and narrow bundle of nervous tissues and support cells which extends from the base of our brain to the upper lumbar region.

It is covered by the three membranes of the cns ie the dura mater arachnoid and the innermost pia mater. The central gray matter contains the neural cell bodies. The spinal cord finishes growing at the age of 4 while the vertebral column finishes growing at age 14 18.

Central area of grey matter shaped like a butterfly and surrounded by white matter in three columns. The narrow indentation that partitions the back surface is known as the dorsal median sulcus or posterior median sulcus and the broader groove that partitions the front surface is called the ventral median fissure or anterior median fissure. The two grooves are named as follows.

Grey matter consists of neuron cell bodies with little myelin and white matter consists of myelinated axons. During development theres a disproportion between spinal cord growth and vertebral column growth.
