The brachial artery is a major blood vessel located in the upper arm and is the main supplier of blood to the arm and hand. The brachial artery continues from the axillary artery at the shoulder and travels down the underside of the arm.

What area is brachial?

The brachial plexus passes from the neck to the axilla and supplies the upper limb. It is formed from the ventral rami of the 5th to 8th cervical nerves and the ascending part of the ventral ramus of the 1st thoracic nerve. Branches from the 4th cervical and the 2nd thoracic ventral ramus may contribute.

Where is the brachial anatomy?

The brachial plexus provides somatic motor and sensory innervation to the upper extremity, including the scapular region. As the brachial plexus travels through the posterior triangle of the neck into the axilla, arm, forearm, and hand, it contains various named regions based on how the plexus is formed.

What is a brachial injury?

The brachial plexus is the network of nerves that sends signals from your spinal cord to your shoulder, arm and hand. A brachial plexus injury occurs when these nerves are stretched, compressed, or in the most serious cases, ripped apart or torn away from the spinal cord.

What is cubital fossa?

The cubital fossa is a small triangular area located on the anterior surface of the elbow, with the apex of the triangle pointing distally. It contains some important structures, on their passage from the arm to forearm. [[1] It is homologous to the popliteal fossa of the lower limb.

What is brachial neuritis & symptoms?

Symptoms of brachial neuritis include: Severe pain in the upper arm or shoulder. Pain usually affecting just one side of the body. After a few hours or days, the pain transitions to weakness, limpness, or paralysis in the muscles of the affected arm or shoulder. Lack of muscle control in the shoulder or arm.

Where is the brachial vein?

The brachial artery and vein can be found by palpating the medial intermuscular septum in the proximal and middle thirds of the arm. The vein is medial and posterior to the artery in this area.

What is long thoracic nerve?

The long thoracic nerve is the motor nerve to the serratus anterior muscle, which functions to pull the scapula forward around the thorax, allowing for anteversion of the arm, and to lift the ribs, assisting in respiration.

What are the muscles of hand?

Where is brachial pulse?

What is brachial plexus surgery?

The goal of brachial plexus surgery is to relieve your pain and restore sensation and motor function to your shoulder, arm and hand. Surgical approaches consider the type, location and extent of nerve injury, as well as your overall health and the impact of injury on your ability to work and quality of life.

Is brachial neuritis a disability?

Brachial plexus damage can range from mild to severe disability in one arm. The disability may be temporary or permanent. When the disability is permanent, treatment may help lessen the severity of the disability.

How do I know if my baby has brachial plexus injury?

When a newborn has brachial plexus injury they may experience: muscle weakness or paralysis in the affected arm or hand. decreased movement or sensation in the upper extremity.

What does nerve damage in arm feel like?

The signs of nerve damage include the following: Numbness or tingling in the hands and feet. Feeling like you’re wearing a tight glove or sock. Muscle weakness, especially in your arms or legs.

What is Bicipital Aponeurosis?

Bicipital aponeurosis or lacertus fibrosus is an aponeurosis from the tendon of biceps brachii muscle in the cubital fossa. … The bicipital aponeurosis is presumed to protect the neurovascular bundle in the cubital fossa such as median nerve and the brachial artery, which pass deep to it [1].

What is your knee pit called?

popliteal fossa Anatomical Parts The popliteal fossa (sometimes referred to colloquially as the knee pit, or poplit) is a shallow depression located at the back of the knee joint. The bones of the popliteal fossa are the femur and the tibia.

What is the elbow pit called?

cubital fossa Anatomical terminology The cubital fossa, chelidon, or elbow pit is the triangular area on the anterior view of the elbow of a human or other hominid animal. It lies anteriorly to the elbow (Latin cubitus) when in standard anatomical position.

What does brachial plexus pain feel like?

Common symptoms of brachial plexus injuries are: Numbness or loss of feeling in the hand or arm. Inability to control or move the shoulder, arm, wrist or hand. An arm that hangs limply.

Can stress cause brachial neuritis?

Other causes: Other factors that stress or injure the nerves and muscles may increase the risk. Some research has linked pregnancy and strenuous exercise to brachial neuritis. Babies may also injure the brachial plexus during birth.

Is brachial neuritis curable?

While there is currently no treatment for the underlying causes of brachial neuritis, the condition usually heals on its own within a few months or a couple years. Treatments for brachial neuritis typically focus on pain management in the shoulder and/or arm.

What is the smallest muscle in the body?

Stapedius muscle is termed to be the smallest skeletal muscle in human body, which has a major role in otology. Stapedius muscle is one of the intratympanic muscles for the regulation of sound.

What is the shortest nerve in the body?

Complete answer: – Trochlear is the shortest cranial nerve present in the human body. – The trochlear nerve controls the superior oblique muscle of the eye. It emerges from the subsequent feature of the midbrain.

What are brachial veins?

The brachial vein is a component of the deep venous system of the upper limb. After forming from the radial and ulnar veins1, the brachial vein travels from the cubital fossa superiorly to become the axillary vein.

Why are there two brachial veins?

The brachial veins are usually 2 in number and they are located on either side of the brachial artery. They are usually formed by the union of the radial and the ulnar venae comitantes, near the level of the elbow [1].

Is brachial vein superficial?

In human anatomy, the brachial veins are venae comitantes of the brachial artery in the arm proper. Because they are deep to muscle, they are considered deep veins.

What is winged scapula?

The term ‘winged scapula’ (also scapula alata) is used when the muscles of the scapula are too weak or paralyzed, resulting in a limited ability to stabilize the scapula. As a result, the medial or lateral borders of the scapula protrudes from back, like wings.

How do you test for thoracic nerve damage?

The test for identifying a long thoracic nerve injury is the ‘serratus wall test’. The patient is asked to face a wall, standing about two feet from the wall and then push against the wall with flat palms at waist level.
