Arteries of Lower Limbs01:20

Arteries of Lower Limbs

4.8K
The external iliac artery transitions out of the body cavity, entering the femoral region of the lower leg, and is renamed the femoral artery at the point where it traverses the body wall. This artery is responsible for the distribution of blood to the thigh's deep muscles and the skin's ventral and lateral regions, achieved through several minor branches and the lateral deep femoral artery, which also spawns a lateral circumflex artery. The knee area receives blood from the genicular...

Veins of Lower Limbs01:15

Veins of Lower Limbs

2.6K
The human body consists of an intricate network of veins responsible for the crucial task of blood drainage from the lower limbs. These veins can be categorized into two main types: deep veins and superficial veins.
Formed by the union of the medial and lateral plantar veins, the posterior tibial vein, rising through the calf muscle, assimilates the fibular vein. The anterior tibial vein, a superior extension of the foot's dorsalis pedis vein, merges with the posterior tibial vein at the...

Veins of Upper Limbs

4.3K
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...

Arteries of the Upper Limbs

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...

Bones of the Upper Limb: Ulna01:15

Bones of the Upper Limb: Ulna

4.5K
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

4.8K
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...

Area of Science:

  • Neuroscience
  • Psychology
  • Body Perception

Background:

  • Phantom limb phenomena, including sensations and pain in a missing limb, are widely experienced but poorly understood.
  • Existing research often focuses on body image's role in maintaining phantom limb sensations.
  • A distinction between body image and body schema is often overlooked, yet crucial for understanding phantom limbs.

Purpose of the Study:

  • To review the literature on phantom limb phenomena, focusing on the distinction between body image and body schema.
  • To propose a novel hypothesis regarding the specific contributions of motor and somatosensory body schemas to phantom limb experiences.

Main Methods:

  • Literature review of studies on phantom limb phenomena.
  • Conceptual analysis distinguishing body image, body schema, motor body schema, and somatosensory body schema.
  • Development of a novel hypothesis based on these distinctions.

Main Results:

  • The review highlights the importance of body schema over body image in explaining phantom limb phenomena.
  • A distinction is motivated between motor body schema and somatosensory body schema.
  • A novel hypothesis is developed on the differential contributions of these schemas.

Conclusions:

  • Understanding phantom limb phenomena requires differentiating body schema from body image.
  • Distinguishing between motor and somatosensory body schemas offers a new framework for explaining phantom limb experiences.
  • This framework may lead to more targeted interventions for phantom limb pain and sensations.
