Spinal Cord Flashcards
Sontinuous with the medulla oblongata and passes through the foramen magnum of the skull.
Spinal Cord
Midline groove on the front side.
Anterior median fissure
Midline groove on the back side.
Posterior median sulcus
Where sensory axons enter.
Dorsal (posterior) nerve root
Where motor axons exit.
Ventral (anterior) nerve root
Gives rise to motor neurons.
basal plate (ventral side)
Develops into sensory neurons.
alar plate (dorsal side)
A bundle of long nerves extending from the conus medullaris.
Cauda equina (“horse’s tail”)
The tapered, pointed end of the spinal cord.
Conus medullaris
A fibrous extension from the conus medullaris that stabilizes the spinal cord.
Filum terminale
Which nerve root is responsible for motor functions?
The ventral (anterior) nerve root.
Which nerve root is responsible for sensory functions?
What is the function of the cauda equina?
What is the function of the cauda equina?
It consists of spinal nerves that extend beyond the spinal cord to reach their respective vertebral levels.
What is the conus medullaris?
The tapered end of the spinal cord.
