Noradrenaline (also called norepinephrine) is a neurotransmitter primarily found within neurons in the locus coeruleus.

Spinal nerves connect the spinal cord to different parts of the body. Each region controls specific muscles, movements, and bodily functions through distinct nerve pathways.

The spinal cord contains ascending sensory pathways and descending motor pathways that carry information between the body and the brain.

The cerebral cortex is divided into distinct lobes that support functions such as movement, sensation, vision, hearing, language, and higher cognitive processes

The basal ganglia are a group of deep brain structures involved in the control and coordination of movement. They also contribute to learning, habits, motivation, and other cognitive functions through interconnected neural circuits.

The hippocampus is a deep brain structure involved in learning and memory formation
