The correct option is D Contains neurosecretory cells
The brain and the spinal cord are parts of the central nervous system. The brain is divided into - Forebrain, midbrain and the hindbrain.
The major part of the forebrain is the cerebrum. The cerebrum wraps the thalamus which sits above the hypothalamus. The cerebrum contains sensory, motor and association areas. The thalamus is the major coordinating centre for sensory and motor signalling. The hypothalamus contains neurosecretory cells which secrete hypothalamic hormones.
