|---|---|---|---|---|---|
| This narrow band of fibers interconnect cord segments in order to allow intersegmental coordination, they are propriospinal fibers. | fasciculus proprius
🗑
|
||||
| This is a narrow band of fibers immediately adjacent to the gray matter. | fasciculus proprius
🗑
|
||||
| This is a narrow midline area of white matter located anterior to the central canal and posterior to the anterior median fissure. | anterior white commissure
🗑
|
||||
| This lies between the apex of the dorsal horn and the surface of the spinal cord, consists of propriospinal fibers and fibers that enter via the dorsal root. | dorsolateral fasciculus
🗑
|
||||
| In the upper thoracic and cervical regions the dorsal column is made up of what two tracts? | fasciculus cuneatus and gracilis
🗑
|
||||
| What type of information is carried by the dorsal column (funiculus) | discriminative touch, vibration, and limb position and motion
🗑
|
||||
| What is another name for the anteriolateral system | spinothalamic tract
🗑
|
||||
| What type of information is carried by the spinothalamic tract? | pain, temperature, and non-discriminative tactile information
🗑
|
||||
| These tracts are located at the periphery of the lateral funiculus and carry proprioreceptive and tactile information to the cerebellum for posture and coordination. | anterior and posterior spinocerebellar tracts
🗑
|
||||
| These two tracts are concerned with voluntary movements esp skilled movements of distal parts of limbs | lateral and anterior corticospinal tracts
🗑
|
||||
| This tract contains fibers that originate in the red nucleus of the midbrain | rubrospinal tract
🗑
|
||||
| The rubrospinal tract is associated with what functions. | muscle tone, esp excitatory response on limb flexors
🗑
|
||||
| This tract is found in the cervical region, is part of the medial longitudinal fasiculus, and is involved with regulation of head position. | medical vestibulospinal tract
🗑
|
||||
| This tract descends in the anterior funiculus, close to the surface, and exerts an excitatory influence on extensor muscles. | lateral vestibulospinal tract
🗑
|
||||
| This tract originates in the reticular formation of the pons and descends in the anterior funiculus. | medial reticulospinal tract
🗑
|
||||
| This tract originates in the reticular formation of the medulla and descends in the anterior and lateral funiculus. | lateral reticulospinal tract
🗑
|
||||
| The fibers of the lateral reticulospinal tract have what type of influence? | inhibit extensors
🗑
|
||||
| The fibers of the medial reticulospinal tract have what type of influence? | excitatory extensors
🗑
