Anatomical planes and reference lines Flashcard Deck - 9 Cards

Flashcard 1: Identify the spinal cord section characterized by the presence of lateral horns and relatively small ventral/dorsal horns (lack of limb enlargements):

Answer: Thoracic

Extra: The thoracic spinal cord (T1-L2) is distinguished by the presence of the lateral horn (intermediolateral cell column) and the Nucleus Dorsalis of Clarke. 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: The medial lemniscus is positioned more _____ (medially or laterally) as it ascends through the midbrain

Answer: laterally

Flashcard 3: 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

Flashcard 4: What is the medial border of the inguinal (Hesselbach) triangle? _____

Answer: Lateral border of rectus abdominis

Flashcard 5: The _____ lobe of the cerebellum consists of the nodulus (in the vermis) and the flocculi (in the lateral hemispheres).

Answer: flocculonodular

Flashcard 6: The medial lemniscus is initially positioned _____ (medially or laterally) in the caudal medulla

Answer: medially

Flashcard 7: Which brainstem pathway carries fine touch, vibration, and proprioception from the body to the VPL nucleus of the thalamus?

Answer: Medial lemniscus

Extra: The medial lemniscus is formed by the decussation of second-order neurons (internal arcuate fibers) from the nucleus gracilis and cuneatus in the medulla. It carries fine touch, vibration, and proprioception to the VPL nucleus of the thalamus.

Flashcard 8: What brainstem tract carries fine touch, vibration, and conscious proprioception from the contralateral gracile and cuneate nuclei to the thalamus?

Answer: Medial lemniscus

Extra: The medial lemniscus is formed by the decussation of internal arcuate fibers (axons of the second-order neurons from the nucleus gracilis and cuneatus) in the medulla. It carries fine touch, vibration, and conscious proprioception to the Ventral Posterolateral (VPL) nucleus of the thalamus.

Flashcard 9: _____ is identified as number 6 in the cross-section of the spine.

Answer: Central canal of the spinal cord
