Brachii Research Paper

Movement of the deltoid begins in the cerebrum of the brain, but more specifically: in the frontal lobe, the premotor cortex is relaying instructions to the primary motor cortex. The primary motor cortex contains the upper motor neurons whose axons will travel down the pyramids of the medulla oblongata and synapse on lower motor neurons in the anterior gray horns of spinal cord segments C5-C6. From there, the ventral rami of spinal nerves C5-C6 form the superior trunk of the brachial plexus, which splits into two divisions. We will follow the posterior division that supplies to extensor muscles. This posterior division then runs into the posterior cord from which the axillary nerve is derived. The axillary nerve’s motor end innervates the deltoid through its neuromuscular junction.

Descriptive terms are used to name skeletal muscles. Some names give the location in the body. The temporalis muscle is attached to the temporal bone in the skull. The brachialis muscle is attached to the humerus bone, but brachial refers to the main artery in the arm. Some muscles are named for their origins and insertions, like the genioglossus muscle, for example, originates at the chin (geneion) and inserts in the tongue (glossus). Some muscles are named for the arrangement of the fascicle groups. For example the rectus abdominus is the straight muscle that is in the adbominus.

In the text of Lippert she explains that there are many muscles in the body, but were focusing on just the muscles involved with the elbow. “The brachialis muscles, it has two heads and is located on the arm also knows as just the biceps and its actions are to flex the elbow” 3 (p. 152) “The

My name is Rafael Braghini Arêas and my memorable day was on twenty-sixtieth, December, twenty sixteen. My family and I went to the Beto Carrero World and I was happy for seeing my father joked as a child, he, a man super serious! He went in the toys more than me and I didn't achieve to follow him. On the day we went to on the beach.

Several muscles of the upper and lower arm attach at the elbow on the olecranon process. In the posterior compartment of the upper arm, the three heads of the triceps brachii converge into a single tendon that connects

In macroscopic detail, the shoulder looks like the scapula coming up and creating a good base for the tendons. Above, is

Key lies in bringing about greater development in a little-discussed muscle that sits underneath the biceps called the brachialis. A highly defined bodybuilder, the brachialis appears as a thick knot of muscle that pops out of the side of the upper arm when they are flexed and viewed from the rear.

In all his works and contributions, “Biko was not only seen as a South African liberation struggle hero, but also became a universal symbol of resistance against oppression” (SouthAfrica.info). The effects of his approach to the liberation struggle resulted in a wave of student protests against the seemingly racist and oppressive education system of that time. Inspired and influenced by the ideas of W.E.B Du Bois, Marcus Garvey, and thinkers such as Frantz Fannon, Leopold Senghor, the American Black Panther Party and others, Black consciousness became an increasingly growing phenomenon amongst the black South African community, especially with black students. It grew to become recognised as one of the recognised

Knowing the anatomy in the regions of injury is vital when solving for the route cause of the pain. When looking at the shoulder, it is important to understand the locations and names of the various muscles and ligament that allow for specific movement for this appendage. For instance, on the superior side of the shoulder joint, the deltoid muscle works with the supraspinatus to abduct the arm at the shoulder. On the anterior side of the shoulder, the coracobrachialis, serratus anterior, pectoralis major, and pectoralis minor muscles work together to flex and abduct the scapula and humerus anteriorly toward the sternum. This knowledge of anatomy becomes advantageous when used to isolate specific areas through palpation exercises in order to further identify and diagnose the presented

The supraspinatus muscle is the initial muscle for this movement during the first 15 degrees of its arc and past 15 degrees, the deltoid muscle becomes increasingly more effective at abducting the arm. The supraspinatus muscle is one of the musculotendinous support structures called the rotator cuff that surrounds the shoulder. In addition, it also helps to stabilize the shoulder joint by keeping the head of humerus firmly pressed medially against the glenoid fossa of the scapula. The most common form of injury in the shoulder is rotator cuff tendonitis. It involves the tendon of the supraspinatus muscle, which attaches to the upper portion of the upper portion of the humerus at the shoulder joint. Less commonly, the tendon of the infraspinatus

The deep digital flexor muscle is a long and strong muscle that originates from the humerus and attaches on to the palmar aspect of the distal phalanx. It is made up of three different muscle heads that comes together at the level of the carpus to form one common tendon. The three different heads are the humeral head, the ulnar head and the radial head. The humeral head origins from the medial epicondyle of the humerus. The ulnar head arises on the medial aspect of the olecranon and attaches with the main tendon at the level of the carpus. The radial originates from the caudomedial aspect of the radius at approximately the middle third of the forearm and connects with the other parts at the distal end of the radius (Barone, 2000)

It facilitates in extension of the elbow. The triceps brachii is the main agonist supporting the elbow into a full extension. The supinator is a broad muscle in the posterior compartment of the forearm curved around the upper third portion of the radius. Its primary function is to supinate the forearm (MJC, 2016).

The brachial plexus is made up of five large nerves, which come out of the spinal cord between the vertebrae and give movement and feeling to the arm. After coming out of the neck, the nerves come together and then divide amongst the muscles and tissues of the arm. The area of the brachial plexus runs from the neck and passes under the collarbone and is the major area of the nerves of the armpit. When the upper nerves are affected, this is known as Erb’s palsy.

Jules Bianchi was a race car driver from a family of race car drivers. His grandfather, Mauro Bianchi, was a GT racer in the 1960s and his great uncle Lucien raced in Formula One and won the 24 Hours of Le Mans in 1968. Jules was looking to follow in his family tradition until events from nine months ago would end his life at the age of 25. Gone too soon, Jules Bianchi died on July 17.

After seeing how close to the humerus the radial nerve ran, it was easy to understand how mid shaft injuries can lead to radial nerve damage. Not only this, but although we had learnt about the passing of Flexor Digitorum Profundus through Flexor Digitorum Superficialis, it was amazing to see it in real life, it was actually one of the highlights of this dissection for me.
