- 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.
- Interspinales colli musclesMusculi interspinales colliThe interspinales colli are short paired muscles bridging the spinous processes of neighbouring neck vertebrae, from the axis down to T1.
- Interspinales lumborum musclesMusculi interspinales lumborumThe interspinales lumborum are short paired muscles joining the spinous processes of neighbouring lumbar vertebrae on each side of the interspinous ligament.
- Interspinales thoracis musclesMusculi interspinales thoracisThe interspinales thoracis are small, inconstant muscles joining adjacent thoracic spinous processes, found mainly at the top and bottom of the thoracic spine.
- Lateral crico-arytenoid muscleMusculus cricoarytendoideus lateralisThe lateral crico-arytenoid is a small laryngeal muscle that runs from the side of the cricoid to the arytenoid and closes the glottis.
- Lateral head of flexor hallucis brevisCaput laterale flexoris brevis hallucisThis lateral head is the outer half of the big toe's short flexor, lying under the first metatarsal.
- Lateral head of gastrocnemiusCaput laterale musculi gastrocnemiiThe lateral head of gastrocnemius is the outer of the calf muscle's two heads, arising from the lateral femoral condyle above the knee.
- Lateral head of triceps brachiiCaput laterale musculi tricipitis brachiiThe lateral head of triceps brachii arises from the back of the humerus above the radial groove and straightens the elbow.
- Lateral rectus muscleMusculus rectus lateralis bulbi oculiThe lateral rectus is the straight muscle on the outer side of the eyeball that turns the eye away from the nose.
- Latissimus dorsi muscleMusculus latissimus dorsiLatissimus dorsi is the broad, flat muscle of the lower back that sweeps up to the arm and pulls it down and back.
- Levator anguli orisThe levator anguli oris is a deep facial muscle running from the maxilla's canine fossa to the mouth's corner, which it raises.
- Levator labii superiorisThe levator labii superioris is a flat facial muscle running from the lower orbital rim into the upper lip, which it lifts.
- Levator nasolabialisLevator labii superioris alaeque nasi: a narrow muscle beside the nose that lifts both the upper lip and the wing of the nostril.
