Posterior column From Wikipedia, the free encyclopedia. The posterior column (dorsal column) refers to the area of white matter in the middle to posterior side of the spinal cord. It is made up of the gracile fasciculus and the cuneate fasciculus and itself is part of the posterior funiculus.It is part of an ascending pathway that is important for well-localized fine touch and conscious proprioception called the posterior column-medial lemniscus pathway.t is made up of the gracile fasciculus and the cuneate fasciculus and itself is part of the posterior funiculus.

- The most important functions of the vertebral column are as follows: 1  Protection: it encloses the spinal cord, shielding it from damage. 2  Support: it carries the weight of the body above the pelvis (below the pelvis, the lower limbs take over).  Axis: the vertebral column forms the central axis of the body.

Vertebral column The vertebral column houses the spinal canal, a cavity that encloses and protects the spinal cord. There are about 50,000 species of animals that have a vertebral column. The human vertebral column is one of the most-studied examples.

What Is the Difference Between Dorsal and Ventral? A: Dorsal refers to the back side of the body whereas ventral refers to the front side of the body. When discussing bipeds, these terms are interchangeable with the terms posterior and anterior.. These terms can become confusing when talking about both bipeds and quadrupeds.

The Ascending Tracts In this article, we shall look at the anatomy of the ascending tracts, and consider their clinical implications. The dorsal column-medial lemniscal pathway (DCML) carries the sensory modalities of fine touch (tactile sensation), vibration and proprioception. Its name arises from the two major structures that comprise the DCML. In the spinal cord, information travels via the dorsal (posterior) columns.

- The vertebral bodies also send prolongations dorsalwards between the sides of the spinal cord and the muscle-plates. The vertebral centra are unossified, and the tail is strongly heterocercal. From the first dorsal to the last lumbar the vertebral column forms a single curve, most pronounced in the lumbar region. Encyclopaedia Britannica, 11th Edition, Volume 6, Slice 2 Various. This vertebral column, as it is called, is distinctive of all vertebrates.

Difference between neural tube and dorsal nerve cord? The dorsal nerve cord is one of the embryonic features unique to chordates, along with a notochord, a post-anal tail, an endostyle, and pharyngeal slits. The dorsal nerve cord is a hollow cord dorsal to the notochord.orsal means the back side, as opposed to Ventral which is the front side of an organism. In organisms with Bipedalism dorsal is the back and ventral is the front.

- The Spinal Column is also called the vertebral column. The bones in the spine are called vertebrae. The column starts at the base of the skull and continues to the pelvis. Alternate layers of bone (vertebrae) and cartilage (the intervertebral discs) stack vertically one on top of the other in the spinal column.

Posterior columnâmedial lemniscus pathway Posterior column–medial lemniscus pathway (PCML) (also known as the dorsal column-medial lemniscus pathway) is a sensory pathway of the central nervous system that conveys localized sensations of fine touch, vibration, two-point discrimination, and proprioception (position sense) from the skin and joints.he name comes from the two structures that the sensation travels up: the posterior (or dorsal) column of the spinal cord, and the medial lemniscus in the brainstem. The PCML pathway is composed of rapidly conducting, large, myelinated fibers.

What Is the Dorsal Striatum? The dorsal striatum is the part of the brain thought to play an important part in making decisions, motivation, and rewards. It is made up of two subregions, the the lentiform nucleus and the caudate nucleus, and is part of the basal ganglia.In some texts, the dorsal striatum is called the striated body or the corpus striatum, and some experts use the term to define the combination of the internal capsule and the basal ganglia.t is made up of two subregions, the the lentiform nucleus and the caudate nucleus, and is part of the basal ganglia.
