Anatomical Movements00:51

Anatomical Movements

15.6K
Anatomical movements refer to the various actions or motions that can be performed by the body's joints and muscles. These movements are described using specific terms to provide a standardized way of discussing and understanding the range of motion at different joints.
Here are some common anatomical movements:
Flexion and extension motions are in the sagittal (anterior–posterior) plane of motion. These movements take place at the shoulder, hip, elbow, knee, wrist,...

Intrinsically Disordered Proteins02:18

Intrinsically Disordered Proteins

19.4K
Intrinsically disordered proteins are a group of proteins that do not fold into specific three-dimensional structures. Their structural flexibility allows them to complement ordered proteins to perform functions that are inaccessible to rigid structures. They are more common in eukaryotes than prokaryotes and may either be exclusively intrinsically disordered or hybrid proteins, consisting of a mix of ordered and disordered regions. The absence of a rigid structure in these proteins can be...

The Movement of Organelles and Vesicles

6.4K
In eukaryotic cells,  cytoskeletal filaments such as actin, microtubules, and intermediate filaments form a mesh-like cytoskeletal network. These filaments serve as tracks for transporting cellular cargo. Specialized motor proteins use the chemical energy stored in adenosine triphosphate (ATP) for this transport. During interphase, microtubules are polarized, with the plus-end towards the cell periphery and the minus-end towards the cell center. Two microtubule-associated motor proteins,...

Fluid Movement Between Compartments01:18

Fluid Movement Between Compartments

4.0K
The force applied by fluids against a surface, known as hydrostatic pressure, initiates the transfer of fluid among different compartments. Within our blood vessels, the blood's hydrostatic pressure is a result of the heart's pumping action. At the arteriolar end of capillaries, hydrostatic pressure (capillary blood pressure) exceeds the opposing colloid osmotic pressure created primarily by plasma proteins like albumin. This discrepancy in pressure propels plasma and nutrients from the...

Movement Joints in Buildings01:27

Movement Joints in Buildings

347
Movement joints in buildings are essential design elements that accommodate inevitable motions caused by various factors such as temperature changes, moisture content variations, and structural deflections. These motions, if not considered in design and construction, can lead to unsightly or dangerous damage. Movement joints are incorporated in different forms to manage these stresses and allow materials to move without causing distress.
The simplest type of movement joints, working joints, are...

Intracellular Movement of Viruses and Bacteria01:10

Intracellular Movement of Viruses and Bacteria

3.6K
Intracellular bacteria and viruses often comprise a group of highly infectious pathogens that can cause several diseases. Bacterial pathogens include those belonging to the genus Rickettsia responsible for conditions such as rocky mountain spotted fever and the Mediterranean spotted fever; Chlamydia, a genus responsible for a sexually transmitted disease; Coxiella burnetii, an agent responsible for Q fever. Viral pathogens include vaccinia—a poxvirus, and herpes simplex virus—a...

Area of Science:

  • Ophthalmology
  • Neurology
  • Neuroscience

Background:

  • Eye movements are crucial for visual perception, involving gaze stabilization and object tracking.
  • Different types of eye movements are controlled by distinct anatomical substrates within the brain.
  • Disorders of eye movement can indicate localized brain dysfunction or systemic disease.

Purpose of the Study:

  • To highlight the diagnostic utility of assessing eye movements.
  • To emphasize the link between specific eye movement patterns and underlying neurological or systemic conditions.
  • To underscore the importance of eye movement analysis in clinical practice.

Main Methods:

  • Clinical assessment of various eye movement types.
  • Correlation of observed eye movement abnormalities with specific neurological deficits.
  • Review of case studies demonstrating the diagnostic value of eye movement examination.

Main Results:

  • Specific eye movement disorders can be localized to particular brain regions.
  • Abnormalities in eye movements are indicative of various systemic diseases.
  • Effective diagnosis through eye movement assessment facilitates timely treatment initiation.

Conclusions:

  • Eye movement analysis is a valuable, non-invasive diagnostic tool.
  • Understanding the neuroanatomy of eye movements aids in localizing brain lesions.
  • Assessment of eye movements can significantly improve patient outcomes through early diagnosis and treatment.
