1. THE BRAIN – AN ENCHANTED LOOM By, Dr. Shamanthakamani Narendran M.D.(Pead), Ph.D. (Yoga Science)

11. A. Central nervous system B. Peripheral nervous system B1. Somatic nervous system B2. Autonomic nervous system 1. Cerebrum 2. Brainstem 3. Cerebellum 4. Spinal cord Somatic nervous system

13. The BRAIN STEM CONNECTS the BRAIN to the SPINAL CORD.

15. THE CEREBELLUM The CEREBELLUM is the SECOND LARGEST part of the Brain, and is located at the back of the Skull. It coordinates muscle movements.

24. Insight Reasoning Art awareness Scientific skills Imagination Written language Three dimensional awareness Number skills Music awareness Spoken language Left hand control Right hand control RIGHT HEMISPHERE LEFT HEMISPHERE

27. HIGHER FUNCTIONS SUCH AS REASONING, DISCRIMINATION, MEMORY Each Hemisphere of the Cerebrum is divided into Four regions called LOBES . These LOBES are named for the SKULL BONES that cover them, FRONTAL, PARIETAL, TEMPORAL, and OCCIPITAL LOBES .

36. BRAIN GROWTH IN FETUS

43. THE AUTONOMIC NERVOUS SYSTEM [ANS]

48. The Autonomic Nervous System Structure Sympathetic Stimulation Parasympathetic Stimulation Iris (eye muscle) Pupil dilation Pupil constriction Salivary Glands Saliva production reduced Saliva production increased Oral/Nasal Mucosa Mucus production reduced Mucus production increased Heart Heart rate and force increased Heart rate and force decreased Lung Bronchial muscle relaxed Bronchial muscle contracted Stomach Peristalsis reduced Gastric juice secreted; motility increased Small Intestine Motility reduced Digestion increased Large Intestine Motility reduced Secretions and motility increased Liver Increased conversion of glycogen to glucose --- Kidney Decreased urine secretion Increased urine secretion Adrenal medulla Norepinephrine and epinephrine secreted --- Bladder Wall relaxed Sphincter closed Wall contracted Sphincter relaxed
