| nasalis muscle | <anatomy> Compound muscle consisting of: a transverse part (pars transversa musculi nasalis, musculus compressor naris) arising from the maxilla above the root of the canine tooth on each side and forming an aponeurosis across the bridge of the nose; and an alar part (pars alaris musculi nasalis, musculus dilator naris) arising from the maxilla above the lateral incisor and attaching to the wing of the nose; the alar part dilates the nostril; nerve supply, facial. Synonym: musculus nasalis, nasal muscle. (05 Mar 2000) |

| neoplasms, muscle tissue | Neoplasms composed of muscle tissue: skeletal, cardiac, or smooth. The concept does not refer to neoplasms located in muscles. (12 Dec 1998) |
| sternal muscle | <anatomy> An inconstant muscle, running parallel to the sternum across the costosternal origin of the pectoralis major, and usually connected with the sternocleidomastoid and rectus abdominis muscles due to their common development source. Synonym: musculus sternalis, musculus rectus thoracis, sternal muscle. (05 Mar 2000) |
| sternochondroscapular muscle | <anatomy> An occasional muscle arising from the manubrium of the sternum and first costal cartilage and passing lateralward and backward to be inserted into the upper border of the scapula. Synonym: musculus sternochondroscapularis. (05 Mar 2000) |
| sternoclavicular muscle | <anatomy> An occasional muscle, a slip from the subclavius muscle, passing from the upper part of the sternum to the clavicle beneath the pectoralis major muscle. Synonym: musculus sternoclavicularis. (05 Mar 2000) |
| sternocostalis muscle | <anatomy, muscle> Origin, dorsal surface of xiphoid cartilage and lower portion of dorsal surface of body of sternum; insertion, second to sixth costal cartilages; action, contributes to depression of ribs, narrowing chest; nerve supply, intercostal. Synonym: musculus transversus thoracis, musculus triangularis sterni, sternocostalis muscle, transverse muscle of thorax. (05 Mar 2000) |
| sternocostal part of pectoralis major muscle | pars sternocostalis musculi pectoralis majoris, sternocostal head of pectoralis major |
| sternomastoid muscle | <anatomy, muscle> This is one of two muscles located on the front of the neckwhich serve to turn the head from side to side. Origin, sternum and clavicle; insertion, mastoid process; action, bends the head to the same side, rotates the head, raises the chin to the opposite side, together bend head forward and elevate chin.

| nerve of tensor tympani muscle | <anatomy> A branch of the mandibular nerve conveying fibres from the motor root of the trigeminal nerve which pass through the otic ganglion without synapse to supply the tensor tympani muscle. Synonym: nervus tensoris tympani. (05 Mar 2000) |
| nerve of tensor veli palatini muscle | <anatomy> A branch of the mandibular nerveconveying fibres from the motor root of the trigeminal nerve which pass through the otic ganglion without synapse to supply the tensor veli palatini muscle. Synonym: nervus tensoris veli palatini. (05 Mar 2000) |

| nerve to thyrohyoid muscle | <anatomy> The thyrohyoid branch, contains fibres of the first and second cervical nerves that have accompanied the hypoglossal nerve to the suprahyoid region, then branch from it to reach the thyrohyoid muscle. Synonym: ramus thyrohyoideus ansae cervicalis. (05 Mar 2000) |
| straight part of cricothyroid muscle | <anatomy> See: cricothyroid muscle. (05 Mar 2000) |
| striated muscle | <physiology> Muscle in which the repeating units (sarcomeres) of the contractile myofibrils are arranged in registry throughout the cell, resulting in transverse or oblique striations observable at the level of the light microscope, for example the voluntary (skeletal) and cardiac muscle of vertebrates.
