Question

Branching tree like processes of white matter called ............ are located in ............. of CNS.

• A. funiculi, spinal cord
• B. folia, medulla oblongata
• C. corpora striata, cerebrum
• D. arbor vitae, cerebellum

Hint:

Arbor vitae is the tree-like white matter structure in the cerebellum that plays a key role in transmitting signals within the CNS.

Answer 1

The Correct Option is D

Step 1: Understanding the structure of the CNS.
The arbor vitae is a branching structure of white matter found in the cerebellum. It is responsible for transmitting signals from the cerebellar cortex to the rest of the CNS.
Step 2: Analyzing the options.
(A) funiculi, spinal cord: Incorrect. Funiculi are bundles of white matter in the spinal cord, but they are not tree-like processes.
(B) folia, medulla oblongata: Incorrect. Folia are the folds of the cerebellum, not found in the medulla oblongata.
(C) corpora striata, cerebrum: Incorrect. The corpora striata is part of the basal ganglia in the cerebrum but does not consist of tree-like structures.
(D) arbor vitae, cerebellum: Correct. Arbor vitae is a branching tree-like structure found in the white matter of the cerebellum.
Step 3: Conclusion.
The correct answer is (D) arbor vitae, cerebellum, as it describes the branching white matter structures in the cerebellum.
