Study Notes

Overview of the Nervous System

The nervous system regulates and improves life experiences; practices like yoga can significantly enhance its function.
Yoga activates the parasympathetic nervous system, promoting rest, relaxation, and digestion, which lowers stress and boosts mental clarity.
Regular yoga practice increases endorphin production, acting as a natural mood enhancer, while spinal movements impact the Central Nervous System (CNS).

Anatomy of the Nervous System

The nervous system consists of nerves distributed throughout the body, including the Central Nervous System (CNS) and Peripheral Nervous System (PNS).
CNS comprises the brain and spinal cord, processes sensory information, and formulates responses to stimuli.
Spinal cord acts as a conduit for signals between the brain and body, responsible for both voluntary actions (e.g., walking) and involuntary reflexes.

Central Nervous System (CNS)

The CNS is divided into:
- Brain: Interprets sensory information; historically seen as the primary source of thoughts, emotions, and decisions.
- Spinal Cord: Transmits electrical impulses and is protected by vertebrae, facilitating communication throughout the body.

Peripheral Nervous System (PNS)

The PNS branches from the spinal cord to other body parts, including:
- Sensory Nerves: Involved in senses, pain perception, temperature, and stretch.
- Motor Nerves: Control voluntary movements and involuntary functions.
Contains two key components:
- Somatic Nervous System: Governs voluntary movements.
- Autonomic Nervous System: Regulates involuntary functions like heart rate, digestion, and breathing.

Techniques to Support Nervous System Health

Activities beneficial for nervous system balance include:
- Shaking, toning, tapping, deep stretching, breathing exercises, twisting, and crossing the midline.

Role of Diet and Sleep

A balanced diet rich in vitamins, minerals, and antioxidants supports nerve health; inflammatory foods can stress the nervous system.
Quality sleep allows for body repair and regeneration, essential for a functioning nervous system; poor sleep contributes to stress and impairs nervous system performance.
Yoga promotes healthy sleep patterns and acts as a movement meditation.

Interconnectedness of Body and Brain

Understanding the nervous system reveals the strong connection between physical health and mental well-being.
Environmental factors can influence nervous system health; while not always controllable, practices that support its function can lead to better self-regulation.
Improved self-regulation enhances personal empowerment, leading to greater control over actions and decisions.
