It has relatively small ventral and dorsal horns compared to the cervical and lumbar enlargements, as it does not provide motor innervation to the limbs.

Flashcard 2: Identify the spinal cord level based on these histological features: oval shape, largest amount of white matter, and presence of both fasciculus gracilis and fasciculus cuneatus: _____

Answer: Cervical

Answer: limbic

Flashcard 4: The large intestine is characterized histologically by abundant _____ cells

Answer: ipsi

Flashcard 7: Which lymph node cluster drains the kidney? _____
