- 生物力学 生物力学
- 人类的机动运动.
- 肌肉骨系统 运动器官系统
背景情况:
- 内在和外在的足部肌肉对于步行时的足部稳定和推进至关重要.
- 了解它们的功能相互作用是理解步态动态的关键.
研究的目的:
- 为了阐明在行走周期期间内在和外在足部肌肉之间的功能关系.
- 研究不同步行阶段的特定内在和外在肌肉的时间和活动模式.
主要方法:
- 电肌图 (EMG) 用于测量13名健康男性的内在 (quadratus plantae,abductor hallucis) 和外在 (flexor hallucis longus,flexor digitorum longus,tibialis posterior) 足部肌肉的活动.
- 使用ANOVA分析了不同步态阶段 (制动和推进) 的肌肉发作的时间和活动水平.
主要成果:
- 内在肌肉,特别是引体幻觉和四角体肌肉,与某些外在肌肉 ( flexor digitorum longus,后肌) 相比,显示出明显更早的激活发作.
- 在晚期推进阶段,外在肌肉活动减少,而内在肌肉保持了持续的活动.

Muscles of the Leg that Move the Foot and Toes
1.8K
The human leg comprises an intricate system of muscles that facilitate the movement of feet and toes. Within this system, the muscles are categorized into the anterior, lateral, and posterior compartments, each with a unique set of muscles carrying out specific functions.
Anterior Compartment
The anterior compartment includes muscles that contribute to the dorsiflexion of the foot. This compartment houses the tibialis anterior, extensor hallucis longus, and extensor digitorum longus muscles....

Bones of the Lower Limb: Tibia and Fibula
3.9K
The tibia is the main weight-bearing bone of the lower leg. It is larger than the fibula with which it is paired. The tibia is also the second longest bone in the body and is located right below the skin. The proximal end of the tibia forms the medial and the lateral condyle, which articulates with the condyles of the femur to form the knee joint. Between the articulating surfaces is the irregular elevated area known as the intercondylar eminence that serves as the inferior attachment point for...

Muscles that Move the Leg
2.2K
The movement of the legs is facilitated by numerous muscles located within the anterior, medial, and posterior compartments of the thigh.
Anterior Compartment
The quadriceps femoris, the most visible muscle of the anterior compartment, is integral for leg extension and thigh flexion. It is formed by merging four distinct muscles — the vastus lateralis, vastus medialis, vastus intermedius, and rectus femoris. The quadriceps tendon, a shared tendon of the four quadriceps muscles, is affixed...

Ankle Joint
1.7K
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...

Excitation-Contraction Coupling in Skeletal Muscles
8.5K
Excitation-contraction coupling is a series of events that occur between generating an action potential and initiating a muscle contraction. It occurs at the triad, a structure found in skeletal muscle fibers that comprise a T-tubule and terminal cisternae of the sarcoplasmic reticulum on each side. These triads are visible in longitudinally sectioned muscle fibers. They are typically located at the A-I junction — the junction between the A and I bands of the sarcomere.

Actin Treadmilling
8.1K
Actin filaments undergo polymerization and depolymerization from either end. The polymerization and depolymerization rates depend on the cytosolic concentration of free G-actins. The polymerization rate is generally higher at the plus or barbed end, while the depolymerization rate is higher at the minus or pointed end. At a steady state, critical concentration describes the concentration of free G-actin monomers at which the polymerization rate at the plus end is equal to that of the...
