舌骨下肌群(infrahyoid muscles)由4 條肌肉組成,除了甲狀舌骨肌(thyrohyoid muscle)外,其餘
3 條肌肉是由下列何者支配?
副神經(accessory nerve) 舌下神經(hypoglossal nerve)
第一至三頸神經之腹側枝(ventral rami) 第四至六頸神經之腹側枝

ANS VENTRAL RAMI OF ANSA CERVICALIS C123

3 下列有關脊髓白質(white matter)的敘述,何者正確?
前外側系統(anterolateral system)傳遞痛、溫和粗觸覺
腹側皮質脊髓徑(ventral corticospinal tract)為已交叉的神經纖維
薄束(fasciculus gracilis)存在於前索(anterior funiculus)中
楔狀束(fasciculus cuneatus)存在於全段脊髓白質

ANS A



THE SPINOTHALAMIC TRACT

The spinothalamic tract is a sensory pathway originating in the spinal cord. It transmits information to the thalamus about pain,temperature, itch and crude touch. The pathway decussates at the level of the spinal cord, rather than in the brainstem like the posterior column-medial lemniscus pathway and corticospinal tract.


4 下列何者對足底長韌帶(long plantar ligament)及足底短韌帶(short plantar ligament)的敘述錯誤?
足底長韌帶在淺層,足底短韌帶在深層
足底長韌帶屬於距下關節(subtalar joint)的韌帶
兩者後面皆附著於跟骨(calcaneus)
兩者前面皆有附著至骰骨(cuboid

6 腕隧道(Carpal tunnel)中,不包含下列何種構造?
食指屈指淺肌(2nd flexor digitorum superficialis)
橈側屈腕肌(flexor carpi radialis)
正中神經(median nerve)
小指屈指深肌(5th flexor digitorum profundus)
