Reticular Dermis01:15

Reticular Dermis

4.6K
The papillary and reticular dermis are the two layers of the dermis. They are made of connective tissue with fibers of collagen extending from one to the other, making the border between the two somewhat indistinct. The dermal papillae extending into the epidermis belong to the papillary layer, whereas the dense collagen fiber bundles below belong to the reticular layer.
Reticular Layer
Underlying the papillary layer is the much thicker reticular layer, composed of dense, irregular connective...

Papillary Dermis01:11

Papillary Dermis

5.8K
Dermis
The dermis might be considered the "core" of the integumentary system, as distinct from the epidermis and hypodermis. It contains blood and lymph vessels, nerves, and other structures, such as hair follicles and sweat glands. The dermis is made of two layers of connective tissue that comprise an interconnected mesh of elastin and collagenous fibers, produced by fibroblasts.
Papillary Layer
The papillary layer is made of loose, areolar connective tissue, which means the collagen...

The Effect of Aging on Tissues01:19

The Effect of Aging on Tissues

3.6K
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

5.7K
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...

Sutures of the Skull01:22

Sutures of the Skull

13.8K
The human skull is composed of several bones that come together to protect the brain and support the structures of the face. The junctions where these bones meet are called sutures.
Sutures are immobile joints between adjacent bones of the skull. The narrow gap between the bones is filled with dense, fibrous connective tissue that unites the bones. The long sutures located between the skull bones are not straight but instead follow irregular, tightly twisting paths. These twisting lines tightly...

Elastin is Responsible for Tissue Elasticity01:12

Elastin is Responsible for Tissue Elasticity

2.4K
Elastic fiber contains the protein elastin along with lesser amounts of other proteins and glycoproteins. The main property of elastin is that it will return to its original shape after being stretched or compressed. Elastic fibers are prominent in elastic tissues found in skin and the elastic ligaments of the vertebral column.
Ligaments and tendons are made of dense regular connective tissue, but in ligaments not all fibers are parallel. Dense regular elastic tissue contains elastin fibers and...

Area of Science:

  • Anatomy
  • Dermatology
  • Lymphatic System Research

Background:

  • Previous studies using light and electron microscopy failed to identify distinct anatomical structures or histological differences related to skin wrinkles.
  • The histological basis for the formation of facial wrinkles and creases remained unclear.

Purpose of the Study:

  • To investigate the potential relationship between facial wrinkles and the underlying lymphatic vessels and associated perilymphatic fat.
  • To determine if lymphatic structures contribute to the anatomical basis of skin wrinkles.

Main Methods:

  • Cadaveric skin, adipose tissue, and muscle samples were collected from three facial sites: forehead crease, crow's feet, and nasojugal crease.
  • Immunohistochemistry and laser confocal microscopy were employed to identify and examine lymphatic vessels and perilymphatic fat.
  • Quantitative measurements were taken to assess the proximity of lymphatic structures to wrinkles.

Main Results:

  • A major lymphatic vessel surrounded by a distinct tube of perilymphatic fat was consistently identified directly beneath every examined wrinkle.
  • Statistical analysis confirmed a significant association between wrinkle location and the presence of these lymphatic structures.
  • Immunofluorescence and histological criteria confirmed the identification of lymphatic vessels, further validated by tracer studies.

Conclusions:

  • The study identified a novel anatomical basis for facial wrinkles, involving underlying lymphatic vessels and perilymphatic fat.
  • Understanding this anatomical relationship is crucial for avoiding inadvertent injection into these vessels during cosmetic procedures.
  • Lymphatic dysregulation's role in inflammation, scarring, and fibrosis may also be indirectly linked to wrinkle formation.
