Muscles of the Shoulder01:23

Muscles of the Shoulder

The muscles surrounding the shoulder girdle, including the clavicle and scapula, primarily stabilize the scapula. This stable base allows other muscles to move the humerus effectively. Scapular movements often mirror those of the humerus and extend its range of motion. For instance, raising the arm above the head would not be feasible without simultaneous upward rotation of the scapula.

The anterior thoracic muscles include the serratus anterior, subclavius, and...
Muscles that Move the Arm01:31

Muscles that Move the Arm

Nine muscles are involved in arm movements. Two of these, the pectoralis major and latissimus dorsi, originate from the axial skeleton and are called axial muscles. The other seven originate from the scapula and are called the scapular muscles.
The pectoralis major has two origins. Its clavicular head originates on the medial half of the clavicle. In contrast, the sternocostal head originates on the costal cartilages of ribs 1-6, the sternum, and the aponeurosis of the external oblique of the...
Axial and Appendicular Muscles01:18

Axial and Appendicular Muscles

Skeletal muscles, the key players in our body's movement, can be classified into two groups based on their location and function: axial muscles and appendicular muscles. These classifications reflect the primary roles the muscles play in the body's structure and movement.
Axial Muscles
Axial muscles, situated along the body's midline, are intricately connected to the axial skeleton, which includes the skull, spine, ribs, and sternum. These muscles facilitate facial expressions and play a...
Muscles of the Thorax01:25

Muscles of the Thorax

The thorax muscles are central to the body's respiration and provide essential support and movement for the upper body. They are intricately designed to facilitate the complex breathing process while also contributing to the structural integrity and mobility of the chest and upper limbs.
The diaphragm is at the core of thoracic musculature, the primary muscle involved in breathing. This expansive, dome-shaped muscle marks the division between the thoracic and abdominal cavities. It originates...
Muscles of the Anterior Neck01:26

Muscles of the Anterior Neck

The anterior neck muscles are the group of muscles covering the front part of the neck. These muscles are classified into three subgroups. The first one is the superficial muscles, the most visible muscles in the front of the neck. It includes the platysma and sternocleidomastoid. The second group is the suprahyoid muscles, located above the hyoid bone. This group comprises the digastric, mylohyoid, geniohyoid, and stylohyoid. Lastly, the infrahyoid muscles are found below the hyoid bone and...
Muscles of the Abdomen01:21

Muscles of the Abdomen

The abdominal wall encircles the abdominal cavity, providing flexible protection and shielding the internal organs from harm. It is bordered at the top by the xiphoid process and costal margins, at the back by the vertebral column, and at the bottom by the pelvic bones and inguinal ligament. The abdominal wall is divided into two regions — the anterolateral and posterior regions.
Anterolateral Region
The anterolateral region comprises five paired muscles classified into the lateral and anterior...

Area of Science:

  • Anatomy
  • Human Morphology
  • Musculoskeletal System

Background:

  • Langer's arch is an uncommon muscular variation located in the axillary region.
  • Anatomical variations can impact surgical procedures and understanding their prevalence is crucial.

Observation:

  • A case report details an axillary arch discovered in the right axilla of a 50-year-old male cadaver.
  • The observed arch originated from the anterior border of the latissimus dorsi muscle.

Findings:

  • The axillary arch connected the latissimus dorsi to the short head of the biceps brachii.
  • This finding represents a specific instance of Langer's arch, a rare anatomical variant.

Implications:

  • Understanding such muscular variations is vital for surgeons operating in the axillary region.
  • Further research into the embryological and genetic basis of Langer's arch may clarify its development and clinical significance.
