This crossword contains the following questions and answers:

The cerebrum is the largest part of the brain in mammals. It is composed of the frontal, parietal, occipital, and temporal lobes. cerebrum
This lobe lies between the occipital bone and the parieto-occipital sulcus. It functions to receive and interpret visual signals. Occipital lobe
These are the shallow groves in the surface of the cerebrum. Sulci
This lobe lies between the temporal bone and the lateral sulcus. It functions in memory, vison, learning, hearing, and emotional behavior. temporal lobe

The spinal or nerve cord is located in the vertebral foramen. It begins at the foramen magnum and ends at the conus medullaris in the lumbar region. It conducts sensory impulses to the brain and motor impulses from the brain to the body spinal cord
These structures lie between the parietal bones and the central sulcus. They function in integration of sensory information with the exception of vision, hearing, and smell. parietal lobes
These are the thick folds in the surface of the cerebrum. gyri
