Neuroanatomy Flashcard Deck - 10 Cards
Flashcard 201: The _____ is the region of the spinal cord gray matter that contains the cell bodies of lower motor neurons.
Answer: Anterior (ventral) horn
Extra: The anterior (ventral) horn contains the cell bodies of alpha motor neurons (lower motor neurons). Damage to these neurons results in lower motor neuron (LMN) signs.
Flashcard 202: The primary visual (striate) cortex is divided into _____ and _____ gyri via the calcarine fissure
Answer: cuneus

Lateral view of important areas of the brain
The primary motor cortex, in the frontal lobe, is the origin of the fibers of the pyramidal tract.
The primary and secondary auditory cortices, where auditory input is processed, are located in the temporal lobe. The primary visual cortex is located at the occipital pole and is surrounded by the secondary visual cortex.
Different functions converge at association areas. The most well-known examples are the motor (Broca) and sensory (Wernicke) areas of speech, which are commonly located in the dominant hemisphere.

Flashcard 206: If both dorsal column fasciculi (gracilis and cuneatus) are present, the spinal cord level is _____
Answer: T6 and above
Extra: The fasciculus gracilis (medial) is present throughout the entire length of the spinal cord. The fasciculus cuneatus (lateral) is only present at level T6 and above. Therefore, both fasciculi are visible on cross-section only at levels T6 and above.
Flashcard 207: What cells synthesize the myelin for cranial nerves III through XII?
_____
Answer: Schwann cells
