Spinal Nerves: Plexus I01:22

Spinal Nerves: Plexus I

1.1K
Nerve plexuses are networks of interlacing nerves that serve as communication hubs to distribute and organize nerve action across various body regions. The nerve plexuses are organized into the cervical plexus located in the neck region, brachial plexus in the shoulder area, lumbar plexus found in the lower back, sacral plexus situated in the pelvis, and coccygeal plexus located in the coccygeal region.
The Cervical Plexus
The cervical plexus, formed by the anterior rami of the first four...

Bones of the Upper Limb: Radius01:09

Bones of the Upper Limb: Radius

2.3K
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...

Arteries of the Upper Limbs01:12

Arteries of the Upper Limbs

758
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...

Peripheral Arterial Disease II: Clinical Manifestations and Diagnostic Evaluation01:21

Peripheral Arterial Disease II: Clinical Manifestations and Diagnostic Evaluation

23
Clinical manifestationsPeripheral Arterial Disease (PAD) manifests through a range of symptoms, from the characteristic intermittent claudication to atypical presentations and severe complications in advanced stages. Intermittent claudication, a hallmark symptom of PAD, presents as exercise-induced muscle pain that typically resolves within minutes of rest. This pain is reproducible and stems from inadequate blood flow, leading to the accumulation of lactic acid produced during anaerobic...

Bones of the Upper Limb: Ulna01:15

Bones of the Upper Limb: Ulna

2.3K
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...

Assessment of Radial Pulse
The radial pulse, located at the wrist, is often the preferred site for assessing peripheral pulse because of its accessibility and dependability. The process of determining the radial pulse involves several steps:

Area of Science:

  • Neuroscience
  • Anatomy
  • Orthopedic Surgery

Background:

  • The radial nerve, a major brachial plexus branch, is susceptible to compression.
  • Radial nerve entrapment is the third most frequent upper limb compressive neuropathy.
  • Posterior interosseus nerve syndrome is the most common radial nerve compression neuropathy.

Purpose of the Study:

  • To detail radial nerve compressive neuropathies.
  • To emphasize the anatomical factors influencing these conditions.
  • To highlight diagnostic challenges and potential pitfalls for clinicians.

Main Methods:

  • Review of anatomical literature.
  • Analysis of clinical case presentations.
  • Correlation of anatomical variations with clinical symptoms.

Main Results:

  • Radial nerve entrapment can occur anywhere along its course.
  • Anatomical variations are frequently implicated in radial nerve compression.
  • Posterior interosseus nerve syndrome is a common manifestation.

Conclusions:

  • Accurate diagnosis requires thorough knowledge of radial nerve anatomy.
  • Familiarity with anatomical variations aids in identifying compression sites.
  • Understanding anatomical nuances improves patient prognoses and treatment strategies.
