- 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 gyriGyri orbitalesThe four gyri on the concave underside of the frontal lobe, arranged around an H-shaped orbital sulcus above the roof of the orbit.
- Orbital part of inferior frontal gyrusThe front and lowest section of the inferior frontal gyrus, lying below the anterior limb of the lateral sulcus and curving onto the orbital surface.
- 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.
- Orbitofrontal branches of anterior cerebral arteryRami orbitofrontales arteriae cerebri anteriorisBranches of the anterior cerebral artery that run forward under the frontal lobe to supply its medial orbital surface and the olfactory bulb and tract.
- OropharynxPars oralis pharyngisThe middle part of the pharynx, behind the mouth, running from the soft palate down to the upper edge of the epiglottis.
- Palatine boneOs palatinumAn L-shaped paired bone at the rear of the nasal cavity that completes the hard palate and reaches up into the orbit.
- Palatine tonsilTonsilla palatinaA paired mass of lymphoid tissue in the side wall of the oropharynx, lodged between the palatoglossal and palatopharyngeal arches.
- Palatopharyngeus muscleMusculus palatopharyngeusA long, thin muscle running from the soft palate down the side wall of the pharynx, raising the posterior palatal arch.
- Palmar branch of median nerveRamus palmaris nervi medianiA cutaneous branch of the median nerve that leaves it above the wrist and crosses over the flexor retinaculum to the palm.
- Palmar branch of ulnar nerveRamus palmaris nervi ulnarisA small cutaneous branch of the ulnar nerve that arises in the forearm and supplies skin over the hypothenar side of the palm and wrist.
- Palmar capitohamate ligamentLigamentum capitohamatum palmareA short, strong band on the palm side of the wrist that ties the capitate to the hamate in the distal carpal row.
- Palmar carpal branch of radial arteryRamus carpeus palmaris arteriae radialisA small branch of the radial artery that crosses the front of the lower radius to form the palmar carpal network with the ulnar artery.
- Palmar carpometacarpal ligamentsLigamenta carpometacarpea palmariaBands on the palmar side of the hand that tie the distal carpal bones to the bases of the second to fifth metacarpals.
- Palmar digital veinsVenae digitales palmaresSmall veins on the palmar side of the fingers that drain the finger pads and communicate with the dorsal veins and the palmar venous arches.
- Palmar interossei musclesMusculi interossei palmaresThe palmar interossei are small muscles between the metacarpals that pull the fingers together towards the middle finger.
- Palmar interphalangeal ligamentsLigamenta interphalangea palmariaThe palmar plates of the finger joints: dense pads on the front of each interphalangeal joint that stop the fingers bending backwards.
- Palmar lunotriquetral ligamentLigamentum lunotriquetrum palmareThe palmar band of the ligament complex that joins the lunate to the triquetrum in the proximal row of carpal bones.
- Palmar metacarpal arteriesArteriae metacarpeae palmaresThree or four small arteries from the deep palmar arch that run distally over the interossei towards the finger clefts.
- Palmar metacarpal ligamentsLigamenta metacarpea palmariaShort transverse bands on the palmar side of the hand joining the bases of neighbouring finger metacarpals.
- Palmar radio-ulnar ligamentLigamentum radioulnare palmareA narrow band on the front of the distal radio-ulnar joint, joining the front rim of the radius's ulnar notch to the ulnar head.
- Palmar scaphotriquetral ligamentLigamentum scaphotriquetrum palmareA palmar wrist ligament that arches from the triquetrum to the scaphoid, crossing the front of the midcarpal joint distal to the lunate.
- Palmar trapezoideocapitate ligamentLigamentum trapezoideocapitatum palmareA short palmar ligament of the distal carpal row that binds the trapezoid to the capitate on the palm side of the wrist.
- 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.
