| internal anal sphincter | <anatomy> A smooth muscle ring, formed by an increase of the circular fibres of the rectum, situated at the upper end of the anal canal, internal to the outer voluntary external anal sphincter. This sphincter is maximally-contracted when the rectal ampulla is at rest -empty or relaxed to accommodate a distending faecal mass. It is inhibited with filling of the ampulla, increased distension and peristalsis. Synonym: musculus sphincter ani internus, internal sphincter muscle of anus. (05 Mar 2000) |
| external anal sphincter | A fusiform ring of striated muscular fibres surrounding the anus, attached posteriorly to the coccyx and anteriorly to the central tendon of the perineum; it is subdivided, often indistinctly, into a subcutaneous part, a superficial part and a deep part for descriptive purposes. Synonym: musculus sphincter ani externus, external sphincter muscle of anus. (05 Mar 2000) |

| rotatory spasm | A disorder of unknown cause, manifested as a restricted dystonia, localised to some of the neck muscles, especially the sternomastoid and trapezius; occurs in adults and tends to progress slowly; the head movements increase with standing and walking and decrease with contractual stimuli, e.g., touching the chin or neck. Synonym: dystonic torticollis, rotatory spasm, rotatory tic. (05 Mar 2000) |
| phonic spasm | A spasmodic contraction of the intrinsic muscles of the larynx excited by attempted phonation, producing either adductor or abductor subtypes caused by central nervous system disease. A localised form of movement disorder. Synonym: phonic spasm, spastic dysphonia. (05 Mar 2000) |
