Summary
Children with congenital upper limb deficiencies (ULDs) show impaired body perception, particularly regarding hands and limbs. This impacts their understanding of body parts and spatial awareness.
Area of Science:
- Developmental Psychology
- Neuroscience
- Pediatrics
Background:
- Effective motor function and body awareness are crucial for development.
- Lexical-semantic knowledge of affected body parts is reduced in children with limb deficiencies.
- Body knowledge in children with congenital upper limb deficiencies (ULDs) remains underexplored.
Purpose of the Study:
- To investigate body perception in children with congenital ULDs.
- To compare body knowledge between children with ULDs and typically developing peers.
Main Methods:
- Involved six children with congenital ULDs and 14 controls (ages 5-11).
- Utilized self-portrait drawing and verbal questioning about body part names.
- Assessed visuospatial and lexical-semantic body knowledge.
Main Results:
- Children with ULDs were more likely to omit hands in drawings.
- Lower correct response rates for upper limbs, arms, hands, legs, and feet in children with ULDs.
- Significant differences in body part representation and naming compared to controls.
Conclusions:
- Children with ULDs exhibit diminished visuospatial knowledge of hands.
- Reduced lexical-semantic knowledge extends to both upper and lower limbs in children with ULDs.
- Congenital ULDs impact holistic body schema development.

The upper and lower limb initially develops as a small bulge called a limb bud, which appears on the lateral side of the early embryo. The upper limb bud appears near the end of the fourth week of development, with the lower limb bud appearing shortly after.
Initially, the limb buds consist of a core of mesenchyme covered by a layer of ectoderm. The ectoderm at the end of the limb bud thickens to form a narrow crest called the apical ectodermal ridge. This ridge stimulates the underlying...

01:19Bones of the Upper Limb: Humerus
6.6K
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...

01:15Bones of the Upper Limb: Ulna
4.0K
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...

01:12Arteries of the Upper Limbs
1.9K
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...

01:09Bones of the Upper Limb: Radius
4.3K
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...

01:07Development of the Limb Synovial Joints
2.1K
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.
