Muscles · NeckPlatysmaPlatysma is a broad, thin sheet of muscle lying just under the skin of the front and side of the neck, from chest to jaw.
Muscles · Lower limbPopliteus muscleMusculus popliteusA thin, triangular muscle in the floor of the popliteal fossa that unlocks the fully straightened knee.
Muscles · NeckPosterior belly of digastric muscleVenter posterior musculi digastriciThe posterior belly of digastric is the longer rear half of the digastric, running from the mastoid notch forwards to the hyoid.
Muscles · NeckPosterior crico-arytenoid muscleMusculus cricoarytenoideus posteriorThe posterior crico-arytenoid is a fan-shaped laryngeal muscle on the back of the cricoid and the only one that opens the glottis.
Muscles · HeadProcerus muscleMusculus procerusThe procerus is a small, pyramid-shaped muscle over the bridge of the nose that drags the skin between the brows down.
Muscles · Upper limbPronator quadratusPronator quadratus is a flat, square muscle across the lower front of the forearm that turns the palm downward.
Muscles · Lower limbPsoas majorA long, thick muscle beside the lumbar spine that runs down over the pelvic brim to the lesser trochanter, joining iliacus.
Muscles · TrunkPubo-analis muscleMusculus puboanalisThe pubo-analis is a band of levator ani fibres that runs from the pubis back to the anal canal, blending with its sphincters.
Muscles · TrunkPubococcygeus muscleMusculus pubococcygeusPubococcygeus is the main front part of levator ani, running from the back of the pubis to the coccyx in the pelvic floor.
Muscles · TrunkPyramidalis muscleMusculus pyramidalisPyramidalis is a small triangular muscle low on the front of the abdomen, lying in front of rectus abdominis inside its sheath.
Muscles · Lower limbQuadratus femoris muscleMusculus quadratus femorisA flat, oblong muscle at the back of the hip, running straight across from the ischial tuberosity to the intertrochanteric crest.
Muscles · BackQuadratus lumborum muscleMusculus quadratus lumborumQuadratus lumborum is a flat, four-sided muscle of the posterior abdominal wall, joining the iliac crest to the twelfth rib and lumbar vertebrae.
Muscles · Lower limbQuadratus plantae muscleMusculus quadratus plantaeA flat, two-headed muscle in the sole that runs from the heel bone to the tendon of flexor digitorum longus.
Muscles · Upper limbRadial head of flexor digitorum superficialisCaput radiale flexoris superficialis digitorumThe radial head is the thin lower origin of flexor digitorum superficialis, arising from the front of the radius below the elbow.
Muscles · TrunkRectus abdominis muscleMusculus rectus abdominisRectus abdominis is a long paired strap muscle lying either side of the midline in the front abdominal wall.
Muscles · NeckRectus anterior capitis muscleMusculus rectus capitis anteriorRectus capitis anterior is a short, flat muscle running from the front of the atlas to the skull base; it nods the head.
Muscles · Lower limbRectus femoris muscleMusculus rectus femorisRectus femoris is the straight, central part of the quadriceps group in the anterior thigh, crossing both the hip and the knee.
Muscles · NeckRectus lateralis capitis muscleMusculus rectus capitis lateralisRectus capitis lateralis is a short muscle joining the transverse process of the atlas to the jugular process of the occipital bone.
Muscles · NeckRectus posterior major capitis muscleMusculus rectus posterior major capitisRectus capitis posterior major is a suboccipital muscle that widens upwards from the spine of the axis to the occipital bone.
Muscles · NeckRectus posterior minor capitis muscleMusculus rectus posterior minor capitisRectus capitis posterior minor is a small suboccipital muscle running from the back of the atlas to the occipital bone near the midline.
Muscles · BackRhomboid major muscleMusculus rhomboideus majorRhomboid major is a flat, diamond-shaped muscle of the upper back that ties the scapula's medial border to the thoracic spine.
Muscles · BackRhomboid minor muscleMusculus rhomboideus minorRhomboid minor is a small, flat upper back muscle running from the lowest neck spines to the scapula at the root of its spine.
Muscles · HeadRisorius muscleMusculus risoriusThe risorius is a thin, variable cheek muscle running from the parotid fascia to the mouth's corner, which it draws sideways.
Muscles · NeckRotatoresThe rotatores are the deepest small back muscles, each running from a transverse process to the lamina of the vertebra just above.
