The Spinal cord originates from
(a) cerebrum
(b) medulla
(c) pons
(d) cerebellum
Explanation:
The brain is subdivided into the cerebrum, thalamus, hypothalamus, cerebellum and brain stem. The brain stem consists of the midbrain, pons and medulla oblongata. The medulla oblongata is the lowest part of the brain stem from where the spinal cord originates. The spinal cord is a long cylindrical structure consisting of a bundle of nerve fibres, running through the vertebral column of the backbone. Hence, (b) is the correct option.
