概括
脚和第一个甲松关节 (MTP1) 位置显著影响长 (FHL) 肌.
科学领域:
- 生物力学 生物力学
- 整形外科 整形外科 整形外科
- 脚和脚手术 脚和脚手术
背景情况:
- 长 (Flexor Hallucis Longus,简称FHL) 肌对于足部生物力学至关重要,它影响着步态稳定性和第一大足关节 (MTP1) 曲.
- 过度的压力会导致FHL的问题,如炎症和功能性硬,特别是在运动员中.
- 脚和MTP1关节运动对FHL动态的确切影响尚未完全理解.
研究的目的:
- 调查脚和MTP1关节位置之间的关系及其对FHL肌外流的影响.
- 为了分析不同的关节配置如何影响FHL位移在后侧轮的FHL位移.
- 测试这样的假设:脚和MTP1运动显著改变肌位移,而脚下屈曲导致最多的变化.
主要方法:
- 使用了九个尸体标本 (18英尺).
- 在FHL肌的近距离和远距离部位上放置了痕标记.
- 测量了9个结合的脚位置 (中性,背,脚下) 和MTP1 (中性,背,脚下) 的肌标志物位移.
主要成果:
- 脚足底屈曲,特别是MTP1足底屈曲,诱导了FHL的最大近位滑动 (高达1.3±0.7厘米).
- 随着脚在脚下曲,MTP1脚下曲导致1.3 ± 0.7厘米的外出,中性MTP1在1.2 ± 0.4厘米,和MTP1背部曲在0.44 ± 0.5厘米.
- 脚和MTP1关节的位置直接影响了FHL的距离变化.
结论:
- 在后轮的FHL肌外流受到结合脚和MTP1关节位置的显著影响.
- 脚的足底屈曲促进近接FHL的滑动,而背部屈曲导致远距离的滑动.
- 这些发现提高了对脚和MTP1关节力学和FHL行为之间的机械相互作用的理解,尽管存在静态无负荷模型的局限性.

Ankle Joint
3.1K
The ankle is formed by the talocrural joint (crural = leg). It consists of the articulations between the talus bone of the foot and the distal ends of the tibia and fibula of the leg. The superior aspect of the talus bone is square-shaped and has three areas of articulation. The top of the talus articulates with the inferior tibia. This is the portion of the ankle joint that carries the body weight between the leg and foot. The sides of the talus are firmly held in position by the articulations...

Role of Affect in Interpersonal Attraction
240
Affect plays a crucial role in shaping interpersonal evaluations and perceptions. Emotions influence how individuals judge and respond to others, often determining whether interactions are viewed positively or negatively. This effect can manifest directly through interactions with the person in question or indirectly via associations with unrelated emotional experiences.Direct Effects of Affect on AttractionAffect directly influences interpersonal attraction when a person’s behavior...

Structural Joints: Synovial Joints
7.4K
Synovial joints are the most common type of joint in the body. A key structural characteristic for a synovial joint is the presence of a joint cavity. This fluid-filled space is where the articulating surfaces of the bones contact each other. Also, unlike fibrous or cartilaginous joints, the articulating bone surfaces at a synovial joint are not directly connected to each other with fibrous connective tissue or cartilage. This gives the bones of a synovial joint the ability to move smoothly...

Structural Joints: Fibrous Joints
3.9K
Fibrous joints are a type of joint where the bones are connected by fibrous connective tissue. These joints provide stability and minimal to no movement between the articulating bones. There are three types of fibrous joints.
Suture
All the bones of the skull, except for the mandible, are joined to each other by a fibrous joint called a suture. The fibrous connective tissue found at a suture strongly unites the adjacent skull bones and thus helps to protect the brain and form the face. In...

Structural Joints: Cartilaginous Joints
4.3K
As the name indicates, at a cartilaginous joint, the adjacent bones are united by cartilage, a tough but flexible type of connective tissue. Unlike synovial joints, these types of joints lack a joint cavity and involve bones joined together by either hyaline cartilage or fibrocartilage.
There are two types of cartilaginous joints:
Synchondrosis
A synchondrosis ("joined by cartilage") is a cartilaginous joint where bones are connected by hyaline cartilage. Synchondrosis may be temporary...

Joints
35.9K
Joints, also called articulations or articular surfaces, are points at which ligaments or other tissues connect adjacent bones. Joints permit movement and stability, and can be classified based on their structure or function.
Structural joint classifications are based on the material that makes up the joint as well as whether or not the joint contains a space between the bones. Joints are structurally classified as fibrous, cartilaginous, or synovial.
Fibrous Joints Are Immovable
