what structure separates the subclavian artery and vein
anterior scalene muscle
rectus abdominus
Rectus abdominis
Arises from the pubis.
Inserts into 5th, 6th, 7th costal cartilages.
The muscle lies in the rectal sheath, which also contains the superior and inferior epigastric artery and vein.
Action: flexion of thoracic and lumbar spine.
Nerve supply: anterior primary rami of T7-12.
Which one of the following structures does not pass posteriorly to the medial malleolus?
Posterior tibial artery
Tibial nerve
Tibialis anterior tendon
Tendon of flexor digitorum longus
Tendon of flexor hallucis longus
Tibilais anterior tendon

two major functions of bicep brachia
supiantion and elbow flexion
bicep femories long and short head innervation
The short head of biceps femoris, which may occasionally be absent, is innervated by the common peroneal component of the sciatic nerve. The long head is innervated by the tibial division of the sciatic nerve.
Post-herpetic neuralgia is the most common complication of shingles
neuralgia
The correct answer is the long head of biceps brachii. The coracoid process of the scapula is the site of origin of coracobrachialis and the short head of biceps brachii, as well as the site of insertion of pectoralis minor. It is also the site of attachment for the coracoclavicular, coracoacromial and coracohumeral ligaments.
The long head of biceps brachii originates from the supraglenoid tubercle. Its tendon passes through the shoulder joint and down the humerus in the intertubercular groove before meeting the belly of the muscle.

Which one of the following structures separates the intervertebral disks from the spinal cord?
The posterior longitudinal ligament overlies the posterior aspect of the vertebral bodies. It also overlies the posterior aspect of the intervertebral disks.
Which one of the following carpal bones is a sesamoid bone in the tendon of flexor carpi ulnaris?
pisiform
muscles inserts onto the lesser tuberostiy of the the humerus?
where do the other rotator cuff muscles insert
subscapularis
With the exception of subscapularis which inserts into the lesser tuberosity, the muscles of the rotator cuff insert into the greater tuberosity.
