A bundle of nerves

The neurological system consists of the brain, nerves and the spine. Nerves have limited ability to regenerate and need proactive protection

The command centre: The brain gathers data from organs such as the eyes, ears and skin to monitor both the external environment and internal conditions. It meticulously processes this input, interprets it and integrates it with memories and knowledge to formulate appropriate responses. It sends signals to muscles and glands through the body. Be it the movement of a limb, the secretion of hormones, or the regulation of vital functions like heart rate, digestion and temperature, the neurological system ensures these actions occur seamlessly to maintain internal balance— homeostasis.

The brain also enables higher cognitive processes essential for human experience. It facilitates thought, reasoning, and complex decision-making. The intricate network of neurological processes supports everyday actions and shapes our understanding of the world and ourselves.
“I am a bundle of nerves”: From a doctor's perspective, when someone says that, they are likely describing feeling extremely nervous, anxious, or stressed. It is a state of heightened emotional arousal and physiological readiness for action. Metaphorically, it refers to the sensation of heightened nervousness, where one might feel tense, jittery, or overwhelmed by emotions. Physiologically, this feeling can be attributed to the activation of the sympathetic nervous system, which is responsible for the fight or flight response. During times of stress or anxiety, the sympathetic nervous system releases hormones like adrenaline, causing increased heart rate, rapid breathing, and heightened alertness. These physical responses prepare the body to react quickly to perceived threats or challenges. Being such a bundle underscores the interconnectedness between our emotions and the nervous system’s response.
