Which of the following muscles is innervated by the axillary nerve?
deltoid and teres minor
Which nerve supplies the deltoid muscle?
Axillary nerve C5 and C6, a branch of the posterior chord of the brachial plexus
What is the Sensory pattern of the skin for the axillary nerve?
Its sensory distribution is the skin overlying the deltoid muscle.
What are the major plexus and nerves tht serve the deltoid muscle?
Brachial plexus thru axillary nerve
If the axillary nerve was damaged what muscle would be at risk of paralysis or atrophy?
Axillary nerve supplies the deltoid and the teres minor mucsles. So you wouldn't be able to abduct your arm otherwise. It is also the lateral cord of the brachial plexus.
Why injections are given at deltoid?
To prevent injury to axillary nerve, which is located in the relatively upper part of deltoid.
What are some causes of deltoid muscle pain?
The axillary nerve, which orginates from root C7 of the brachial plexus, innervates the deltoid . The radial nerve also orginates off the same cord. So, it may be linked to your cervical spine, or the deltoid muscle compressing the nerve.
What causes pain in the back of the shoulder?
The most common cause of nerve endings to the shoulder results from a proximal humerus fracture. Running circumferential to the proximal end of the humerus is the axillary nerve. Injury to the humerus such as fractures or subluxation can directly injure the axillary nerve resulting in possible sensation loss or muscle weakness around the deltoid, teres minor and triceps muscle. Other causes of injury: - Injections (for e.g. cortisone) and vaccinations: if given too high in the anterior (front part) aspect of the deltoid, may result in the rupture of the axillary nerve
Which muscle is innervated by the phrenic nerve?
Diaphragm
Is the orbicularis oculi muscle innervated by the facial nerve?
Yes
What muscle is innervated by the trochlear nerve?
The superior oblique muscles
Which nerve controls the movement of the lattisimus dorsi muscle?
The muscle is innervated by Thoracodorsal nerve, from the posterior cord of brachial plexus.
