GENERAL HISTOLOGY

Detailed explanation-1: -Short association fibers form connections between gyri that are in close proximity to each other. Distant regions of the cortex are connected by long association fibers; these include the cingulum adjacent to the cingulate gyrus.

Detailed explanation-2: -The cingulum is a major association tract. The cingulum forms the white matter core of the cingulate gyrus and links from this to the entorhinal cortex. Another major association tract is the superior longitudinal fasciculus (SLF) that has three parts.

Detailed explanation-3: -The largest bundle forms the corpus callosum. Association Fibers-fibers that connect regions of the cerebral cortex within one hemisphere. Two categories are recognized: short association fibers connect adjacent gyri; long association fibers connect distant gyri (different lobes);
