Nerves · Lower limbMedial plantar nerveNervus plantaris medialisThe bigger end branch of the tibial nerve, supplying the inner sole, a few short foot muscles and the medial three and a half toes.
Veins · FootMedial plantar veinsVenae plantares medialesDeep veins along the medial side of the sole that accompany the medial plantar artery and help form the posterior tibial veins.
Arteries · HeadMedial pontine branches of basilar arteryRami mediales pontis arteriae basilarisSmall paramedian branches from the back of the basilar artery that pierce the pons near the midline to supply its inner part.
Muscles · HeadMedial pterygoid muscleMusculus pterygoideus medialisThe medial pterygoid is a thick, four-sided chewing muscle on the inner side of the mandibular ramus that closes the jaw.
Muscles · HeadMedial rectus muscleMusculus rectus medialisThe medial rectus is the straight eye muscle on the nasal side of the eyeball that turns the eye inwards towards the nose.
Nerves · Whole bodyMedial reticulospinal tractTractus reticulospinalis medialis tractusA descending pathway from the reticular formation of the pons to the spinal cord, running in the anterior funiculus and driving the antigravity muscles.
Nerves · Lower limbMedial sural cutaneous nerveNervus cutaneus medialis suraeA cutaneous branch of the tibial nerve that descends between the heads of gastrocnemius and joins a fibular branch to form the sural nerve.
Joints and ligaments · FootMedial talocalcaneal ligamentLigamentum talocalcaneum medialeA small band on the inner side of the hindfoot running from the medial tubercle of the talus to the sustentaculum tali of the calcaneus.
Nerves · Whole bodyMedial vestibulospinal tractTractus vestibulospinalis medialisA short descending pathway from the medial vestibular nucleus to the cervical spinal cord that steadies the head and links head and eye movements.
Veins · Upper limbMedian antebrachial veinVena mediana antebrachiiA superficial vein running up the middle of the anterior forearm from the palm towards the elbow.
Joints and ligaments · NeckMedian cricothyroid ligamentLigamentum cricothyreoideum medianumA strong midline band at the front of the larynx joining the lower edge of the thyroid cartilage to the arch of the cricoid.
Veins · Upper limbMedian cubital veinVena mediana cubitiA short superficial vein crossing the front of the elbow that links the cephalic vein to the basilic vein.
Nerves · Upper limbMedian nerveNervus medianusA major nerve of the upper limb, formed by roots from two plexus cords, that reaches the hand by the carpal tunnel.
Arteries · TrunkMedian sacral arteryArteria sacralis medianaA slender unpaired artery that leaves the back of the aorta just above its bifurcation and runs down the midline of the sacrum to the coccyx.
Lymphatics · TrunkMedian sacral nodesNodi sacrales medianiLymph nodes lying in the midline on the front of the sacrum, along the median sacral artery behind the rectum.
Joints and ligaments · NeckMedian thyrohyoid ligamentLigamentum thyreohyoideum medianumThe thickened central part of the thyrohyoid membrane, joining the thyroid notch of the larynx to the central body of the hyoid.
Brain and spinal cord · HeadMedulla oblongataThe lowest part of the brainstem, a tapering column between the pons and the spinal cord that holds vital centres for breathing and circulation.
Nerves · HeadMeningeal branch of maxillary nerveRamus meningeus nervi maxillarisA small branch of the maxillary nerve, given off inside the skull, that supplies the dura mater of the front of the middle cranial fossa.
Joints and ligaments · Lower limbMeniscopatellar ligamentLigamentum meniscopatellareA thin capsular band at the front of the knee running from the side of the patella to the front edge of the meniscus below it.
Arteries · HeadMental branch of inferior alveolar arteryRamus mentalis arteriae alveolaris inferiorisThe terminal branch of the inferior alveolar artery, leaving the mandible through the mental foramen to supply the chin and lower lip.
Nerves · HeadMental nerveNervus mentalisA sensory branch of the inferior alveolar nerve that leaves the jaw through the mental foramen to supply the chin and lower lip.
Muscles · HeadMentalis muscleMusculus mentalisThe mentalis is a small, cone-shaped muscle at the point of the chin that raises and pushes out the lower lip, as in pouting.
Organs · AbdomenMeso-appendixMesoappendixThe small triangular fold of peritoneum that suspends the vermiform appendix from the back of the ileal mesentery.
Organs · AbdomenMesocolonThe fold of peritoneum and connective tissue that attaches the colon to the back wall of the abdomen and carries its vessels.
