Yoga Glossary

Every term the quiz and the anatomy reference use — all 58 of them — explained the yoga way: what it is, what it does in practice, and the poses that engage or lengthen it. Built for teacher-training students who meet these words in class and want them in plain language, one tap from wherever they appear.

Muscles

Deltoids

The cap muscles of the shoulders — they lift the arms in every direction.

Serratus anterior

The finger-like muscle along the side ribs that anchors the shoulder blades to the torso.

Latissimus dorsi

The broad back muscles that pull the arms down and back and lengthen in folds and Child's Pose.

Trapezius

The kite-shaped muscle of the upper back and neck that positions the shoulder blades.

Rhomboids

Small muscles between the spine and shoulder blades that draw the blades together.

Rotator cuff

Four small shoulder muscles that keep the ball of the arm bone centered in its socket.

Erector spinae

The paired columns of muscle along the spine that hold you upright and create backbends.

Transversus abdominis

The deepest abdominal layer — a built-in corset that steadies the spine and pelvis.

Rectus abdominis

The front abdominal muscle that flexes the trunk — the classic crunch muscle.

Obliques

The diagonal side-abdominal muscles that rotate and side-bend the trunk.

Intercostals

The small muscles between the ribs that lift and open the ribcage as you breathe.

Diaphragm

The dome-shaped main muscle of breathing, sitting under the ribs.

Pelvic floor

The muscular sling at the base of the pelvis — the floor of the core and the root of Mula Bandha.

Hip flexors (iliopsoas)

The deep muscles that lift the thigh toward the torso — and pull tight from hours of sitting.

Gluteus maximus

The largest muscle in the body — the main engine of hip extension and a backbend stabilizer.

Gluteus medius

The side-hip muscle that keeps the pelvis level whenever you stand on one leg.

Quadriceps

The front-thigh muscles that straighten the knee — the burn in Chair and the Warriors.

Hamstrings

The back-thigh muscles that bend the knee and extend the hip — the limit in most forward folds.

Tibialis anterior

The shin muscle that lifts the front of the foot — the dorsiflexor that balances the calves.

Triceps brachii

The back-of-arm muscle that straightens the elbow — half the engine of Chaturanga.

Biceps brachii

The front-of-arm muscle that bends the elbow — the triceps' partner across the joint.

Joint Actions

Flexion

Closing a joint angle — bending, as the knee bends or the spine rounds forward.

Extension

Opening a joint angle — straightening, as the knee straightens or the spine arches.

Abduction

Moving a limb away from the body's midline — the leg stepping wide, the arm lifting sideways.

Adduction

Moving a limb toward the body's midline — thighs hugging together, arms crossing in front.

External rotation

Rotating a limb outward, away from the midline — the thigh turning out in Warrior II.

Internal rotation

Rotating a limb inward, toward the midline — the subtle partner of turnout.

Dorsiflexion

Drawing the toes toward the shin — the ankle action that stretches the calves in Down Dog.

Plantarflexion

Pointing the foot — pressing through the toes like a dancer or a swimmer's kick.

Breath & Energy

Pranayama

The yogic discipline of breath regulation — working with the breath on purpose.

Bandha (energy locks)

Internal 'locks' — coordinated muscle engagements that direct breath and pressure in the body.

Sankalpa (intention)

A short, heartfelt intention set at the start of practice — a resolve, not a goal list.

Chakras

Root Chakra (Muladhara)

The first chakra, at the base of the spine — grounding, stability, belonging. Element: earth.

Heart Chakra (Anahata)

The fourth chakra, at the center of the chest — love, openness, connection. Element: air.

Third Eye Chakra (Ajna)

The sixth chakra, between the eyebrows — insight, intuition, inner seeing. Element: light.

Crown Chakra (Sahasrara)

The seventh chakra, at the crown of the head — connection, unity, quiet. Element: thought/consciousness.

Foundations

Fascia

The body's continuous web of connective tissue, wrapping every muscle, bone and organ.

Ligaments & Tendons

Tendons connect muscle to bone and move joints; ligaments connect bone to bone and guard them.

Proprioception

The body's position sense — knowing where your limbs are without looking at them.

Not a term: Sun Salutation

Surya Namaskar is a sequence, not a single concept — Mountain, fold, Plank, Chaturanga, Up Dog, Down Dog and the lunges, linked by breath. Each of its poses has its own anatomy card in Pose Anatomy.
