- Oblique head of adductor hallucisCaput obliquum adductoris hallucisThe larger, deeper head of adductor hallucis, slanting across the sole from the middle metatarsal bases to the great toe.
- Oblique head of adductor pollicisCaput obliquum adductoris pollicisThe oblique head of adductor pollicis is the upper part of the thumb adductor, arising from the central bones at the base of the palm.
- Oblique part of cricothyroid musclePars obliqua musculi cricothyreoideiThe oblique part is the rear, more horizontal set of cricothyroid fibres, running from the cricoid arch to the thyroid cartilage's lower horn.
- Obliquus inferior capitis muscleMusculus obliquus inferior capitisObliquus capitis inferior is a thick suboccipital muscle joining the spine of the axis to the atlas and turning the head.
- Obliquus superior capitis muscleMusculus obliquus superior capitisObliquus capitis superior is a small suboccipital muscle running up and back from the atlas to the occipital bone.
- Obturator externusA flat, fan-shaped muscle covering the outside of the obturator membrane and running behind the femoral neck to the trochanteric fossa.
- Obturator internusA fan-shaped muscle lining the side wall of the lesser pelvis, whose tendon turns out through the lesser sciatic foramen to the greater trochanter.
- Occipitalis muscleMusculus occipitalisThe occipitalis is the thin, four-sided back belly of the scalp muscle, running from the back of the skull to the epicranial aponeurosis.
- Omohyoid muscleMusculus omohyoideusOmohyoid is a thin two-bellied strap muscle of the neck that runs from the scapula's upper edge to the hyoid bone.
- Opponens digiti minimi muscle of handMusculus opponens digiti minimi manusOpponens digiti minimi is the deepest hypothenar muscle, rolling the little finger metacarpal forward to cup the palm.
- Opponens pollicis muscleMusculus opponens pollicisOpponens pollicis is a thenar muscle at the base of the thumb that turns the thumb across the palm to meet the fingers.
- Orbicularis oris muscleMusculus orbicularis orisThe orbicularis oris is the ring of muscle inside the lips that surrounds the mouth opening, closing it and pursing the lips.
- Orbital part of orbicularis oculiPars orbitalis musculi orbicularis oculiThe orbital part of orbicularis oculi is the thick outer ring of the eyelid sphincter, lying over the orbital rim and closing the eye tightly.
- Palatopharyngeus muscleMusculus palatopharyngeusA long, thin muscle running from the soft palate down the side wall of the pharynx, raising the posterior palatal arch.
- Palmar interossei musclesMusculi interossei palmaresThe palmar interossei are small muscles between the metacarpals that pull the fingers together towards the middle finger.
- Palmaris longus muscleMusculus palmaris longusPalmaris longus is a slim, often absent forearm muscle whose long tendon runs to the palm and tightens the palmar aponeurosis.
- Palpebral part of orbicularis oculiPars palpebralis musculi orbicularis oculiThe palpebral part of orbicularis oculi is the thin, pale sheet of muscle within both eyelids that closes them gently in blinking and sleep.
- Pectineus muscleMusculus pectineusA flat, four-sided muscle at the top of the inner thigh, running from the pecten pubis to just below the lesser trochanter.
- Pectoralis minor muscleMusculus pectoralis minorPectoralis minor is a thin, triangular chest muscle lying beneath pectoralis major, running from the upper ribs to the coracoid process.
- Piriformis muscleMusculus piriformisA pear-shaped muscle passing from the front of the sacrum through the greater sciatic foramen to the top of the greater trochanter.
- Plantar interossei musclesMusculi interossei plantaresThree small muscles deep in the sole, each lying under a lateral metatarsal and drawing its toe towards the second toe.
- Plantaris muscleMusculus plantarisA small calf muscle behind the knee whose very long, thin tendon runs down between gastrocnemius and soleus to the heel.
