概括
老龄化会降低orbicularis oculi肌肉的功能,导致眼收缩较弱. 表面电肌图 (sEMG) 有效地测量了这些与年龄相关的功能衰退,尽管超结构损伤不是直接原因.
科学领域:
- 眼科医生 眼科 眼科
- 老年学是一门学科.
- 肌肉生理学 肌肉生理学
背景情况:
- 眼肌的年龄相关变化会影响眼功能和美学.
- 之前的研究还没有全面分析与orbicularis衰老相关的结构和功能变化.
- 了解这些变化对于解决与年龄相关的眼疾病至关重要.
研究的目的:
- 通过使用表面电肌图 (sEMG) 调查orbicularis oculi肌肉衰老的功能结果.
- 为了将功能变化与眼肌的超结构性变化相关联.
- 评估衰老对肌肉收缩强度的影响及其与肌肉纤维损伤的关系.
主要方法:
- 招募了26名患有皮肤病的患者,年龄在37-78岁之间.
- 将患者分为两个年龄组:<60岁和≥60岁.
- 进行了超结构和电肌图学检查,将sEMG信号与肌肉损伤相关联.
主要成果:
- 老年患者 (≥60岁) 在sEMG中显示的平均自愿收缩和RMS值明显低于年轻患者 (<60岁).
- 在年龄和肌肉损伤之间没有发现统计学意义上的关联.
- 平均自愿收缩与超结构性损伤程度之间没有相关性.
结论:
- 表面电肌图 (sEMG) 是监测眼肌 (orbicularis oculi) 肌肉中与年龄相关的功能变化的一个有价值的工具.
- 衰老会降低 orbicularis oculi 肌肉的功能能力,这表明收缩强度降低.
- 肌肉纤维的超结构性损伤并不直接导致随着年龄的增长观察到的收缩强度的下降.

The Effect of Aging on Tissues
2.1K
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...

Accessory Structures of the Eye
1.5K
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...

Muscles of the Eye
1.1K
The muscles of the eye are sophisticated structures that control eye movement and focus, allowing for the precise and rapid adjustments necessary for vision. The human eye is controlled by ten muscles — six extraocular muscles, three intraocular muscles, and one primary eyelid retractor muscle.
Extraocular Muscles
The six extraocular muscles surround the eyeball and control its movements. They are responsible for a wide range of eye motions, including looking up, down, left, right, and...

Muscles for Facial Expressions
1.8K
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...

Bone Disorders
3.4K
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...

Aging

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...
