- Clavicular head of pectoralis major musclePars clavicularis musculi pectoralis majorisThe clavicular head is the upper, smaller portion of pectoralis major, running from the inner clavicle to the front of the humerus.
- Coccygeus muscleMusculus coccygeusCoccygeus is a flat, triangular muscle at the back of the pelvic floor, stretched from the ischial spine to the edge of the coccyx.
- DiaphragmDiaphragmaThe diaphragm is the dome-shaped sheet of muscle and tendon separating the chest from the abdomen, and the chief muscle of breathing.
- External abdominal oblique muscleMusculus obliquus externus abdominisThe external oblique is the outermost and largest flat muscle of the side and front of the abdominal wall.
- External anal sphincterSphincter externus aniThe external anal sphincter is the ring of voluntary skeletal muscle around the lower anal canal that keeps the anus closed.
- External intercostal musclesMusculi intercostales externiThe external intercostals are the outermost layer of muscle filling each space between neighbouring ribs, used mainly in breathing in.
- Iliococcygeus muscleMusculus iliococcygeusIliococcygeus is the thin, hindmost sheet of levator ani, stretched from the side wall of the pelvis to the coccyx.
- Inguinal ligamentLigamentum inguinaleThe inguinal ligament is the firm band along the groin, stretched from the front of the iliac crest to the pubic tubercle.
- Innermost intercostal musclesMusculi intercostales intimiThe innermost intercostals are the deepest and thinnest layer of muscle between the ribs, found in the side parts of each space.
- Internal abdominal oblique muscleMusculus obliquus internus abdominisThe internal oblique is the middle of the three flat muscles of the side abdominal wall, lying beneath the external oblique.
- Internal intercostal musclesMusculi intercostales interniThe internal intercostals form the middle layer of muscle between the ribs, used mainly in forced breathing out.
- Levatores breves costarumThe levatores breves costarum are small fan-shaped muscles at the back of the thorax, each running from a vertebra to the rib just below.
- Levatores longi costarumThe levatores longi costarum are slender slips beside the thoracic spine that pass from a vertebra over one rib to the next.
- 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.
- Pubo-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.
- Pubococcygeus muscleMusculus pubococcygeusPubococcygeus is the main front part of levator ani, running from the back of the pubis to the coccyx in the pelvic floor.
- Pyramidalis muscleMusculus pyramidalisPyramidalis is a small triangular muscle low on the front of the abdomen, lying in front of rectus abdominis inside its sheath.
- Rectus abdominis muscleMusculus rectus abdominisRectus abdominis is a long paired strap muscle lying either side of the midline in the front abdominal wall.
- Serratus anterior muscleMusculus serratus anteriorSerratus anterior is the broad, saw-edged muscle on the side of the chest that holds the scapula against the ribs and swings it forward.
- Sternocostal head of pectoralis major musclePars sternocostalis musculi pectoralis majorisThe sternocostal head is the large lower portion of pectoralis major, spreading from the sternum and upper costal cartilages to the humerus.
- Subclavius muscleMusculus subclaviusSubclavius is a small, rounded muscle tucked beneath the clavicle, running from the first rib to the underside of the collarbone.
- Transversus abdominis muscleMusculus transversus abdominisTransversus abdominis is the deepest of the flat abdominal muscles, its fibres wrapping horizontally round the abdomen like a corset.
- Transversus thoracis muscleMusculus transversus thoracisTransversus thoracis is a thin sheet lining the inside of the front chest wall, fanning from the lower sternum to the costal cartilages.
