Butterfly-shaped internal region containing neuronal cell bodies. Dorsal Horn: Receives sensory input.
: Develop your own mnemonics or use established ones to memorize lists of structures and their functions. For example, to remember the 12 pairs of cranial nerves in order, a popular mnemonic is O n O ld O lympus’ T owering T ops, A F inn A nd G erman V iewed S ome H ops. Adding a second part to indicate if each nerve is sensory (S), motor (M), or both (B) can further reinforce functional knowledge: S ome S ay M arry M oney, B ut M y B rother S ays B ig B rains M atter M ore.
: Deep in the temporal lobe, the amygdala acts as a "threat detector," processing fear and triggering the fight-or-flight response. The Movement Story (Frontal Lobe) neuroanatomy notes pdf
Includes the cerebral cortex (gray matter), subcortical white matter, and the basal ganglia. It is responsible for higher-order functions like cognition, memory, and voluntary motor control.
Contains the corpora quadrigemina (superior and inferior colliculi) for visual and auditory reflexes, and the substantia nigra for motor pathway regulation. For example, to remember the 12 pairs of
Located in the posterior cranial fossa, the cerebellum coordinates voluntary movements, maintains posture, controls balance, and plays a role in motor learning. Damage to the cerebellum results in (uncoordinated, clumsy movements). 4. Spinal Cord Anatomy and Major Pathways
: Comprises the brain and the spinal cord, contained within the cranium and vertebral canal. The Movement Story (Frontal Lobe) Includes the cerebral
Support cells; they do not transmit impulses but are essential for neuron function.
12 pairs of nerves that emerge directly from the brain and brainstem.
