In respect to this, what does the supraclavicular nerve innervate?

Supraclavicular nerves. The supraclavicular nerves are three cutaneous nerves that emerge as a common trunk from the cervical plexus before branching to innervate the skin over the upper chest and shoulders.

Also, what does your clavicle protect? The collarbone holds the shoulder up and back, and along with the shoulder blade (scapula) and acromioclavicular (AC) joint helps increase the stability and strength of the shoulder. The collarbone also protects nerves and blood vessels from the neck to the shoulder.

In this way, what muscles are around the clavicle?

Four major muscles of the shoulder region are attached to the clavicle, medially the pectoralis major and the clavicular head of the sternocleidomastoid and laterally the deltoid and the trapezius.

Where does the supraclavicular nerve originate?

The supraclavicular nerves (descending branches) arise from the third and fourth cervical nerves; they emerge beneath the posterior border of the sternocleidomastoideus (sternocleidomastoid muscle), and descend in the posterior triangle of the neck beneath the platysma and deep cervical fascia.

What is supraclavicular fossa?

What does the intercostal nerve do?

Unlike the nerves from the autonomic nervous system that innervate the visceral pleura of the thoracic cavity, the intercostal nerves arise from the somatic nervous system. This enables them to control the contraction of muscles, as well as provide specific sensory information regarding the skin and parietal pleura.

Is supraclavicular part of the neck?

What are supraclavicular lymph nodes?

The supraclavicular lymph nodes are a set of lymph nodes found just above the clavicle or collarbone, toward the hollow of the neck. Swelling and pain in the lymph nodes are signs of an infection and sometimes, a malignancy (a cancerous tumor).

What muscles does the subclavian nerve innervate?

The suprascapular nerve comes off the upper trunk, from roots C5-C6, and innervates the supraspinatus and infraspinatus, which are contributors to the rotator cuff apparatus. Arising from anterior divisions of C5-C6, also from the upper trunk, the subclavian nerve innervates the subclavius muscle.

Where does the long thoracic nerve run?

The long thoracic nerve (LTN) originates from the ventral rami of cervical nerve roots 5, 6, and 7. It traverses the middle scalene muscle in the neck, passes under the brachial plexus and over the first rib. It then travels along and innervates the serratus anterior muscle (SA).

Is the Suprascapular nerve a peripheral nerve?

How do you stretch the muscles around your collarbone?

What is clavicle enlargement?

Asymptomatic enlargement of the clavicle: a review of underlying aetiologies. An asymptomatic enlargement of the medial clavicle is a condition that is often both missed and misdiagnosed. We review the most common causes of an isolated and asymptomatic enlargement of the medial clavicle.

Does the clavicle move?

Motions Available & Range of Movement
During elevation, the clavicle rotates upward on the manubrium, and produces and inferior glide to maintain joint contact. The motions are usually associated with elevation and depression of the scapula.

What is the difference between right and left clavicle?

Generally, the right clavicle occurs on the right side of the body while the left clavicle occurs on the left side of the body. Thus, there is no anatomical or functional difference between right and left clavicle. In brief, the clavicle or the collarbone is a long bone, which occurs directly above the first rib.
