Axial and Appendicular Muscles01:18

Axial and Appendicular Muscles

2.7K
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...

General Case of Eccentric Axial Loading01:12

General Case of Eccentric Axial Loading

486
Unsymmetrical bending occurs when the bending moment applied to a structural member does not align with its principal axis. This misalignment leads to complex stress distributions and deflection patterns that differ from symmetrical bending, which are essential for designing structures to withstand different loading conditions.
Consider a member subjected to equal and opposite forces that are applied along a line that does not coincide with the member's neutral axis. In unsymmetrical...

Overview of the Axial Skeleton01:09

Overview of the Axial Skeleton

9.1K
The skeleton is subdivided into two major divisions—the axial skeleton and the appendicular skeleton. The axial skeleton forms the vertical, central axis of the body. It includes all of the bones of the head, neck, chest, and back. It protects the brain, spinal cord, heart, and lungs. It also serves as the attachment site for muscles that move the head, neck, and back and for muscles that act across the shoulder and hip joints to move their corresponding limbs.
The axial skeleton of the...

Normal Strain under Axial Loading01:20

Normal Strain under Axial Loading

1.1K
Normal strain under axial loading is an important concept in the field of mechanics of materials. Axial loading implies the application of a force along the axis of a material, like a column or bar. This force can either compress or stretch the material. In the context of axial loading, normal strain is the deformation experienced by the material in the direction of the loading force. It's calculated as the change in length divided by the original length of the material. This unitless ratio...

Fimbriae, Pili, and Axial Filaments01:28

Fimbriae, Pili, and Axial Filaments

1.7K
Fimbriae and pili are specialized bacterial surface structures that play pivotal roles in adhesion, genetic exchange, and motility. Composed primarily of pilin protein, these hairlike appendages are crucial for bacterial survival and pathogenicity in various environments.Fimbriae: Adhesion and PathogenicityFimbriae are fine, filamentous structures measuring 2–10 nanometers in diameter and are densely distributed on the bacterial cell surface. They facilitate bacterial adhesion to abiotic...

Eccentric Axial Loading in a Plane of Symmetry01:16

Eccentric Axial Loading in a Plane of Symmetry

566
Eccentric axial loading occurs when an axial load is applied away from the centroidal axis of a structural member. This scenario is common in engineering, where structural elements may not be directly aligned due to various design or functional requirements.

Summary
This summary is machine-generated.

Pediatric ocular axial lengths grow most rapidly in the first 10 months of life and stabilize after 36 months in healthy eyes. This data aids in diagnosing pediatric eye conditions.

Area of Science:

  • Ophthalmology
  • Pediatric Ophthalmology
  • Biometry

Background:

  • Accurate measurement of ocular axial length is crucial for diagnosing and managing various pediatric eye conditions.
  • Establishing normative data for axial length in healthy pediatric eyes is essential for comparison.

Purpose of the Study:

  • To establish a normative model for ocular axial length in pediatric subjects without intraocular pathology.
  • To analyze the pattern of axial length growth in healthy children.

Main Methods:

  • Retrospective chart review of axial lengths from 330 eyes of 165 pediatric subjects examined under anesthesia.
  • Inclusion criteria: absence of intraocular pathology; exclusion criteria: presence of intraocular pathology.
  • Development of an axial length growth model using logarithmic regression, with stratification by age groups.

Main Results:

  • The study included 330 eyes from 165 pediatric subjects with a mean age of 30.62 months.
  • The steepest increase in ocular axial length was observed during the first 10 months of life.
  • No statistically significant axial length growth was detected after 36 months of age.

Conclusions:

  • This study provides the largest dataset of pediatric ocular axial lengths in healthy eyes.
  • The developed axial length model can aid in the diagnosis and management of pediatric ophthalmic diseases.
  • Normative data is critical for identifying deviations from typical growth patterns.
