Arteries of the Upper Limbs01:12

Arteries of the Upper Limbs

2.2K
The subclavian artery transitions into the axillary artery as it exits the chest and enters the axillary region. This artery is critical for supplying blood to the shoulder area, including the head of the humerus, through the humeral circumflex arteries. As the vessel continues into the upper arm or brachium, it becomes the brachial artery. This artery plays a key role in vascularizing the brachial region and bifurcates at the elbow into several branches. These branches include the deep...

Veins of Upper Limbs01:17

Veins of Upper Limbs

4.1K
The human circulatory system, a marvel of biological engineering, is a complex network of vessels that transport blood throughout the body. Among these, the veins responsible for carrying blood from the upper limbs are divided into two categories: deep and superficial.
The deep venous system is primarily composed of the ulnar and radial veins. The ulnar vein, which drains the fingers through the superficial palmar venous arches, and the radial vein, which serves the palms via the deep palmar...

Bones of the Upper Limb: Humerus01:19

Bones of the Upper Limb: Humerus

7.1K
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...

Bones of the Upper Limb: Ulna01:15

Bones of the Upper Limb: Ulna

4.4K
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...

Bones of the Upper Limb: Radius01:09

Bones of the Upper Limb: Radius

4.7K
The radius is longer of the two bones that make up the human antebrachium or forearm. At the proximal end, the radius articulates with the capitulum of the humerus and the radial notch of the ulna to form the elbow joint. At the distal end, the radius articulates with the ulna via the ulnar notch, forming the distal radioulnar joint. Distally, the radius also attaches to the carpal wrist bones (scaphoid and lunate) to form the radiocarpal joint.
The radius has a nail-shaped head, and a...

Development of the Limb Synovial Joints01:07

Development of the Limb Synovial Joints

2.3K
Joints form during embryonic development in conjunction with the formation and growth of the associated bones. The embryonic tissue that gives rise to all bones, cartilage, and connective tissues of the body is called mesenchyme.
The mesenchymal stem cells differentiate into chondrocytes that form the hyaline cartilage, and later the cartilaginous model of the bone. This model further transforms into a bone. This process is known as endochondral ossification.
During development, the limbs...

Area of Science:

  • Biomechanics
  • Human movement analysis
  • Clinical assessment

Background:

  • Optical motion capture is valuable for upper body kinematics and compensatory movement analysis.
  • Standardized protocols with functional relevance are needed for clinical acceptance.

Purpose of the Study:

  • Characterize normative angular joint kinematics for standardized upper limb tasks.
  • Assess the intra-rater reliability of the motion capture protocol.

Main Methods:

  • Twenty adults performed the Pasta Box Task and Cup Transfer Task.
  • Optoelectronic motion capture recorded upper body kinematics (trunk, shoulder, elbow, forearm, wrist).
  • Intra-class correlation assessed intra-rater reliability.

Main Results:

  • Tasks required minimal trunk motion; cross-body movements increased joint range of motion (RoM).
  • Reaching further increased trunk and elbow RoM; pasta transport maintained wrist extension.
  • Cup transfer tasks induced specific wrist flexion/extension and radial/ulnar deviation.
  • Most kinematic measures showed good intra-rater reliability (ICC > 0.75).

Conclusions:

  • The developed protocol and functional tasks offer superior movement sensitivity compared to current clinical assessments.
  • This study provides a normative dataset for quantifying movement compensations in impaired populations.
