Re: [申覆]醫學(ㄧ) 15
※ 引述《Cooperchen (FooFoo)》之銘言：
15. 下列何者不支配肘關節(elbow joint)的運動?
選項(D)尺神經支配的兩條前臂肌肉屈指淺肌與屈指伸肌
都不見有肘關節的運動
因為手邊書籍有限
請問有人有查到相關的佐證嗎?
謝謝!!
Gray's anatomy: elbow joint
Flexion is produced by the action of the Biceps brachii and Brachialis,
assisted by the Brachioradialis and the muscles arising from the medial
condyle of the humerus; extension, by the Triceps brachii and Anconæus,
assisted by the Extensors of the wrist, the Extensor digitorum communis, and
the Extensor digiti quinti proprius.
唯一有可能的是那些the muscles arising from the medial
condyle of the humerus (assited):
The Flexor digitorum profundus (這個沒有)
situated on the ulnar side of the forearm,
immediately beneath the superficial Flexors. It arises from the upper
three-fourths of the volar and medial surfaces of the body of the ulna,
embracing the insertion of the Brachialis above, and extending below to
within a short distance of the Pronator quadratus. It also arises from a
depression on the medial side of the coronoid process; by an aponeurosis from
the upper three-fourths of the dorsal border of the ulna, in common with the
Flexor and Extensor carpi ulnaris; and from the ulnar half of the
interosseous membrane.
The Flexor carpi ulnaris (這個humeral head從medial epicondyle of humerus來)
lies along the ulnar side of the forearm. It arises
by two heads, humeral and ulnar, connected by a tendinous arch, beneath which
the ulnar nerve and posterior ulnar recurrent artery pass. The humeral head
arises from the medial epicondyle of the humerus by the common tendon; the
ulnar head arises from the medial margin of the olecranon and from the upper
two-thirds of the dorsal border of the ulna by an aponeurosis, common to it
and the Extensor carpi ulnaris and Flexor digitorum profundus; and from the
intermuscular septum between it and the Flexor digitorum sublimis.
