Flashcards in Spinal Cord Anatomy Deck (34):
1

The ascending gracile and cuneate fasciculi occupying the dorsal column, and sometimes are named the dorsal funiculus. These fibers carry information related to

tactile, two point discrimination of simultaneously applied pressure, vibration, position, and movement sense and conscious proprioception

2

In the lateral column (funiculus), the neospinothalamic tract (or lateral spinothalamic tract) is located more anteriorly and laterally, and carries

pain, temperature and crude touch information from somatic and visceral structures.

3

The dorsal and ventral spinocerebellar tracts carry

unconscious proprioception information from muscles and joints of the lower extremity to the cerebellum.

4

The ventral column (funiculus) there are four prominent tracts:

1) the paleospinothalamic tract (or anterior spinothalamic tract)
2) the spinoolivary tract
3) the spinoreticular tract
4) the spino-tectal tract.

5

The paleospinothalamic tract (or anterior spinothalamic tract) is located which carry

pain, temperature, and information associated with touch to the brain stem nuclei and to the diencephalon

6

The spinoolivary tract carries

information from Golgi tendon organs to the cerebellum

7

Intersegmental nerve fibers

traveling for several segments (2 to 4) and are located as a thin layer around the gray matter is known as fasciculus proprius, spinospinal or archispinothalamic tract. It carries pain information to the brain stem and diencephalon.

8

The descending tracts originate from

different cortical areas and from brain stem nuclei

9

Descending pathway carry information associated with

maintenance of motor activities such as posture, balance, muscle tone, and visceral and somatic reflex activity. These include the lateral corticospinal tract and the rubrospinal tracts located in the lateral column (funiculus).

10

Lateral corticospinal tract and the rubrospinal tracts located in the lateral column (funiculus). carry

information associated with voluntary movement.

11

Lissauer's tract

wedged between the dorsal horn and the surface of the spinal cord carry the descending fibers of the dorsolateral funiculus (DFL), which regulate incoming pain sensation at the spinal level, and intersegmental fibers.

12

Dorsal column-medial lemniscus tract

carries fine (or light) touch fibers, conscious proprioception, vibration, pressure and 2-point discrimination,

13

Corticospinal tract

carries motor fibers.
