Anatomy SPINAL CORD
1. What is the inferior end of the spinal cord called?
Answer: Conus medullaris

Answer: L1-L2 intervertebral disc level
3. Which structure anchors the spinal cord to the coccyx?
Answer: Filum terminale
4. What is the name of the spinal cord enlargement that gives rise to the nerves of
the upper limb?
Answer: Cervical enlargement
5. The spinal cord is protected by three meningeal layers. From outermost to
innermost, they are:
Answer: Dura mater, arachnoid mater, pia mater
6. The space between the dura mater and the vertebral canal is called the:
Answer: Epidural space
7. What type of neurons are found in the dorsal horn of the spinal cord?
Answer: Sensory (afferent) neurons
,ALVON
8. The lateral horns of the spinal cord contain:
Answer: Preganglionic sympathetic neurons (T1-L2)
9. The central canal of the spinal cord is filled with:
Answer: Cerebrospinal fluid (CSF)
10. Which spinal cord tract carries pain and temperature sensations?
Answer: Spinothalamic tract
11. What is the function of the corticospinal tract?
Answer: Voluntary motor control

Answer: Myotome
14. How many pairs of spinal nerves are there?
Answer: 31 pairs
15. The cauda equina consists of:
Answer: Descending dorsal and ventral roots below L2
16. Which spinal tract is responsible for proprioception and fine touch?
Answer: Dorsal columns (fasciculus gracilis and cuneatus)
17. Damage to the anterior horn cells results in:
Answer: Lower motor neuron signs (e.g., flaccid paralysis)
18. Which spinal cord segment corresponds to the C6 dermatome?
Answer: Thumb
, ALVON
19. A lesion of the right lateral corticospinal tract in the spinal cord causes:
Answer: Ipsilateral motor weakness below the lesion
20. The spinal cord receives its blood supply from the:
Answer: Anterior spinal artery and two posterior spinal arteries21. The decussation
(crossing) of the corticospinal tract fibers occurs at the:
Answer: Pyramids of the medulla oblongata
22. Which part of the spinal cord gray matter contains motor neurons?
Answer: Ventral (anterior) horn

cord?
Answer: Posterior median sulcus
24. What is the name of the groove on the anterior surface of the spinal cord?
Answer: Anterior median fissure
25. The fasciculus gracilis carries sensory input from which part of the body?
Answer: Lower limbs and lower trunk
26. The fasciculus cuneatus carries input from which region?
Answer: Upper limbs and upper trunk (above T6)
27. Which spinal cord tract carries unconscious proprioceptive information to the
cerebellum?
Answer: Spinocerebellar tract
28. A lesion in the dorsal columns will most likely lead to loss of:
Answer: Fine touch, vibration, and proprioception
