Anatomy, Physiology & Pathology Foundations

Explore the body's key systems—anatomy, physiology, and pathology foundations—covering the integumentary, musculoskeletal, nervous, endocrine, digestive, respiratory, cardiovascular, lymphatic, urinary, and reproductive systems, and how they inform yoga practice and teaching.

Explore the cell as the fundamental unit of life, its membrane, organelles, and cytoplasm, and how mitochondria power ATP production while the nucleus stores DNA and glycoprotein tags cells.

Explore the integumentary system, from epidermis and dermis to hair follicles and keratin, and how skin's touch and stretch inform the brain and yoga practice.

Discover the musculoskeletal system, detailing skeletal, smooth, and cardiac muscles, their locations and roles in movement, circulation, digestion, and heat production.

Explore the nervous system's central and peripheral divisions, how neurons form nerves and synapses, and how brain regions with neurotransmitters regulate movement and autonomic responses.

Explore how glands secrete hormones that bind receptor sites to regulate metabolism, sleep, stress, and reproduction, highlighting hypothalamus-pituitary control, thyroid, pancreas, adrenal, pineal melatonin, thymus, and gonads.

Explore the digestive system from embryonic tube to mouth and anus, with liver, gallbladder, pancreas, teeth, and saliva enzymes, peristalsis, bile emulsification, and nutrient and water absorption in the intestines.

Explore how the respiratory system enables oxygen and carbon dioxide exchange through external and internal respiration, alveoli and surfactant, and hemoglobin. Learn how breath guides safe movement.

Explore the thoracic diaphragm anatomy and how breathing influences blood flow and digestion. Practice the 360 breathing drill to engage the diaphragm, pelvic floor, and deep core for healthy movement.

Explore how the heart and a closed network of arteries, veins, and capillaries form two circuits—body and lungs—delivering oxygen and nutrients while removing carbon dioxide.

Explore the lymphatic and immune systems, and see how lymphatic vessels and nodes support immunity; learn how the thymus trains T cells and how organs like tonsils and spleen function.

Explore the urinary system's role in filtering waste and regulating blood pressure through nephrons, kidneys, ureters, bladder, and urethra, and learn why psoas treatment poses risk near these structures.

Explore the male and female reproductive systems, including testes, prostate, semen, ovaries, uterus, fallopian tubes, cervix, vagina, and external genitals, plus hormonal roles in menstruation and pregnancy.

Explore anatomical landmarks and location terms, including cranial, spinal, thoracic, abdominal, pelvic cavities, and mediastinum, plus superior, inferior, proximal, distal, anterior, posterior, medial, and lateral.

Adopt the anatomical position as a neutral start point to describe movement using three planes—transverse, sagittal, and frontal—dividing the body into upper/lower, left/right, and front/back segments.

Learn how movement occurs in sagittal, frontal, and transverse planes, with forward/back in sagittal, side-to-side in frontal, and rotation in transverse, using two panes of glass as a staying-in-a-plane visualization.

Master the full range of joint movements across the spine, shoulders, elbows, wrists, hips, knees, ankles, and jaw, including flexion, extension, rotation, abduction, adduction, protraction, retraction, elevation, and circumspection.

Review key movement terms: plantar flexion and dorsiflexion, pronation and supination, scapular protraction and retraction, elevation and depression, and upward and downward rotation of the scapula.

Explore the living bone: structure, types, growth plates, and joints, plus vertebral, skull, pelvis, and limb anatomy, with emphasis on bone tissue, remodeling, and sensory foot function.

Explore bone pathology, fracture healing and osteoporosis, detailing open vs closed and complete vs incomplete fractures, growth plates, periosteum, remodeling by osteoblasts and osteoclasts, and scoliosis with gentle yoga adaptations.

Explore how the skeleton supports yoga postures and breathing, emphasizing bone-based balance and pelvic foundation. Identify how pelvis, tailbone, and forearm bones affect safety, alignment, and modifications for accessibility.

Examine how synovial joints enable movement, especially ball-and-socket hips and shoulders, and compare immovable sutures with acetabulum and talus-tibia-fibula dynamics.

Explore the structure and movement of synovial joints, including ellipsoid, hinge, pivot, saddle, and gliding joints, plus the roles of synovial fluid, hylan cartilage, ligaments, and the meniscus.

Identify joint pathologies that interrupt yoga, such as sprains versus strains and ligament injuries, and explain management like prolotherapy and strengthening to protect end ranges in arthritis and dislocations.

Explore how yoga postures position joints, assess safe alignments, and modify for safety, while pranayama breathing supports joint health and synovial fluid movement.

Explore skeletal muscle structure from fibers to whole muscles and how actin and myosin interactions with calcium drive isometric, concentric, and eccentric contractions.

Learn about common muscle conditions, including spasms, tears, tendonitis, and carpal tunnel. Discover strategies like Golgi tendon organ reflexes, controlled transitions, and eccentric loading to prevent and manage pain.

Explore how muscles shorten and lengthen in postures such as warrior one, and how to modify to be more accessible. Learn the diaphragm's central role in breathing and accessory muscles.

Explore fascia as the body's compartmentalizing connector that links and separates tissues, not very organized yet resilient to multi-directional tension, and supports infection control via the lymphatic system.

Explore how fascia adapts to movement and breath, how multi-directional practice balances tissue remodeling, and how pranayama and nervous-system safety guide healthy fascia changes.

Explore how to maintain integrity in movement and minimize injury through guidelines for forward folds, back bends, and twists. Learn safe progression and efficient practice.

Align the neck, trunk, and pelvis with cues like neck long, chin tucked, rib tuck, breastbone lifted, and pelvic neutral; use glove German hands and short foot for stability.

Explore using the body by posture type—forward folds, backbends, and twists—while cueing neck relaxation, hips back, and navel in to lock prime movers in backbends.

Explore forward folds with neck relaxed, hips back, and navel in to lengthen back muscles, distribute weight into the lower limbs, and build trunk stability while staying safe.

Learn how to optimize backbends by locking down prime movers first, using cues like squeezing oranges under the armpits to engage smaller spinal stabilizers and protect the Forsett joints.

Explore how twisting postures rely on a tall spine, crown lifting, and even vertebral stacking to preserve rotation, while avoiding side bending and maintaining spine integrity through cues and variations.

Conclude your anatomy, physiology and pathology foundations course for yoga teacher training by embracing the body's adaptability, encouraging ongoing inquiry, and applying dynamic principles to personalized movement practice.
