Summary
Multiple muscular anomalies were found in the right upper limb of a cadaver, including an axillary arch, third head of biceps brachii, reverse palmaris longus, Gantzer's muscle, and enlarged palmaris brevis.
Area of Science:
- Anatomy
- Morphology
- Human Anatomy
Background:
- Anatomical variations are common in human limbs.
- Understanding these variations is crucial for clinical practice.
Observation:
- Multiple muscular anomalies were identified in the flexor compartment of the right upper limb during cadaveric dissection.
- These included an axillary arch, a third head of biceps brachii, a reverse palmaris longus, Gantzer's muscle, and an enlarged palmaris brevis muscle.
Findings:
- Detailed measurements of length, width, and attachments were recorded for each anomalous muscle.
- The study documented a rare combination of anomalies in a single individual.
Implications:
- These anatomical variations can impact surgical procedures and diagnostic interpretations in the upper limb.
- Awareness of such anomalies is essential for anatomists, surgeons, and clinicians.

01:19Bones of the Upper Limb: Humerus
The upper limb consists of the arm, forearm, wrist, and hand bones. The humerus is the single bone of the upper arm region. Proximally, it has a large, spherical, smooth head that articulates with the glenoid cavity of the scapula to form the glenohumeral or shoulder joint. The margin of the head is the anatomical neck, a residual epiphyseal plate. Laterally it extends to form bony projections called the greater tubercle and the lesser tubercle. Next to the tubercles is the surgical neck, a...
01:12Gross Anatomy of Skeletal Muscles
The connective tissues play a significant role in arranging the muscle fibers into a hierarchical structure that forms a complete muscle. Consider a muscle like the bicep brachii, commonly called the bicep. This muscle comprises thousands of muscle fibers enclosed by a protective layer of connective tissue called the endomysium. The endomysium is primarily composed of reticular fibers, a type of thin collagen fiber. It allows the exchange of nutrients and waste products at the fiber level,...
01:15Bones of the Upper Limb: Ulna
The ulna and radius are parallel bones of the antebrachium or the forearm. The ulna lies medially and consists of a bony tip called the olecranon process at its proximal end. This hook-like projection articulates with the olecranon fossa of the humerus and forms the "hinged" ulnohumeral part of the elbow joint. This joint facilitates forearm extension and flexion while preventing its hyperextension. Similarly, the coronoid process, another bony projection on the proximal/anterior side of the...
00:55Skeletal Muscle Anatomy
Skeletal muscle is the most abundant type of muscle in the body. Tendons are the connective tissue that attaches skeletal muscle to bones. Skeletal muscles pull on tendons, which in turn pull on bones to carry out voluntary movements.
01:18Axial 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...

01:21Satellite Stem Cells and Muscular Dystrophy
Satellite stem cells or myosatellite cells are quiescent stem cells that Alexander Mauro first identified in 1961. These cells are located between the sarcolemma, the plasma membrane of muscle fibers, and the basal lamina, the connective tissue sheath covering it. These mononucleated cells are activated in response to muscle injury, can transform into myoblasts, and may form or repair muscle fibers. Myosatellite cells can provide additional myonuclei for muscle regeneration or return to a...
