The Effect of Aging on Tissues01:19

The Effect of Aging on Tissues

4.0K
Several body functions deteriorate with age. The external signs of aging are easily identifiable. For example, the skin becomes dry, less elastic, and thins out, forming wrinkles. The skin of the face begins to appear looser due to a decrease in the levels of elastic and collagen fibers in the connective tissue. Additionally, melanin production in the hair follicle decreases with age, resulting in gray hair. Moreover, the senses of sight and hearing decline, so glasses and hearing aids may...

Muscles for Facial Expressions01:14

Muscles for Facial Expressions

5.4K
The craniofacial muscles are a collection of approximately 20 thin skeletal muscles situated beneath the skin of the face and scalp. These muscles, primarily responsible for the vast array of human facial expressions, originate from the bones or fibrous structures of the skull and extend outwards to connect with the skin. While most skeletal muscles in the body are enveloped in thick fascia, facial muscles generally have a more delicate fascial covering, with the buccinator muscle being a...

Accessory Structures of the Eye

4.2K
Optical perception, or vision, is an extraordinary sense dependent on converting light signals received via the ocular organs. These organs, known as eyes, are securely positioned within the bony cavities of the skull, called orbits. The orbits serve a dual purpose: a protective shield for the ocular globes and a stable attachment point for the soft ocular tissues. The eye's external protective mechanisms include the eyelids, which are edged with lashes that act as a barrier against foreign...

Pharmacokinetics in Geriatric Patients: Effect of Age on Drug Absorption

779
As individuals age, their body's physiology evolves, affecting drug pharmacokinetics. The most apparent changes occur in the gastrointestinal tract, where an increase in gastric pH, a delay in gastric emptying, and a reduction in gastrointestinal motility are observed. Remarkably, these changes do not substantially modify the absorption of orally administered drugs, particularly those absorbed via passive diffusion.Transdermal drug delivery emerges as a highly viable method for older adults due...

Bone Disorders01:29

Bone Disorders

5.8K
Aging and its effect on bone remodeling is the most common cause of bone disorders. In young and healthy people, bone deposition and resorption happen at an equal rate to maintain optimal bone health.
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...

Aging01:26

Aging

929
Aging is a complex biological phenomenon influenced by various processes that affect cellular and systemic functions. Several prominent theories attempt to explain its mechanisms, highlighting cellular limitations, oxidative damage, and hormonal changes as central factors in aging.
Cellular Clock Theory
The cellular clock theory posits that the human lifespan is closely tied to the finite capacity of cells to divide, a phenomenon governed by telomeres, which are protective caps at the ends of...

Summary
This summary is machine-generated.

Aging causes eyebrow lateral end points (EP) to droop, impacting facial aesthetics. Correcting the lateral EP is key for periorbital rejuvenation in older individuals.

Area of Science:

  • Aesthetic surgery
  • Oculoplastics
  • Facial anatomy

Background:

  • Aging significantly alters facial features, including eyebrow position.
  • Dynamic changes in eyebrow position during facial expressions are crucial for aesthetic evaluation.

Purpose of the Study:

  • To evaluate age-related dynamic changes in eyebrow position.
  • To identify specific facial landmarks affected by aging during various facial actions.

Main Methods:

  • Photogrammetry and video recording were used to analyze eyebrow positions.
  • Two age groups (20-30 and 50-70 years) performed six facial actions.
  • Measurements were taken at the medial canthus (MC) and lateral end point (EP).

Main Results:

  • The lateral end point (EP) was significantly lower in the older group across all actions.
  • Reduced vertical eyebrow movement with aging was observed at the lateral EP.
  • Eyebrow position at the medial canthus (MC) remained largely unchanged with aging, except during maximal eye opening and frowning.

Conclusions:

  • Aging causes a significant lowering of the lateral eyebrow end point (EP).
  • Reduced dynamic movement of the lateral eyebrow further accentuates age-related changes.
  • Focusing on the lateral EP is crucial for effective periorbital rejuvenation procedures.
