Hematopoiesis is the biological process of forming, developing, and maintaining all mature blood cell types from a single precursor population1. In an adult human, the body produces between $10^{10}$ and $10^{11}$ new blood cells every day to maintain steady-state levels in circulation1. While adult blood cell production occurs primarily in the bone marrow (mainly within the pelvis, cranium, vertebrae, and sternum)23, the system is governed by fundamental principles of cell potency, embryonic

Conventionally, humans have twelve pairs of cranial nerves, conventionally designated by Roman numerals (I through XII) based on their sequential order of emergence from the brain from front to back (rostral to caudal). Unlike spinal nerves, which emerge from segments of the spinal cord, cranial nerves exit directly from the cranial cavity to distribute innervation primarily to structures in the head and neck.Cerebral vs. Brainstem Origin: The olfactory nerve (CN I) and optic nerve (CN II) emerge

The human nervous system is composed of two primary cell types: neurons, which process information via electrochemical signals, and glial cells, which provide essential support and protection. While neurons were historically viewed as the sole drivers of thought and behavior, contemporary research reveals that glia—including astrocytes, microglia, and oligodendrocytes—actively regulate brain metabolism, immune defense, and synaptic activity. Despite popular myths suggesting a massive surplus of
