What is the relations of scalenus anterior...?
scalenus anterior has origin from? and is inserted into the anterior border of the first rib?
Anteriorly it is covered by prevertebral fascia and phrenic nerve crosses from the lateral border to the medial border downwards. Anteriorly lies the subclavian vein. In addition the suprascapular artery and the transverse cervical artery crosses anteriorly. Posteriorly lies the subclavian artery together with the brachial plexus.
Shit.. My memory is failing me...
Hmm.. wad abt sternocleidomastoid?
round tendon to sternal notch and muscular head to medial one third of clavicle
inserted into mastoid process and medial one third of superior nuchal line
extend the head and flex the cervix when acting bilaterally and when only one muscle acts, it turns head to face upwrds towrds opposite side..
ok so anteriorly there is the internal carotid artery and just posterior to the anterior border of the sterno is the internal jugular vein. Together with the vagus, the artery and vein are enclosed in the carotid sheath..
posteriorly there is the subclavian vein and at the jn of upper and middle one third of the post border is the superficial cervical nerve.. ok medially is the trachea eso and thyroid
