Natural and Artificial Concepts01:24

Natural and Artificial Concepts

547
In psychology, concepts can be divided into two categories: natural and artificial. Natural concepts are formed through direct or indirect experiences. For example, consider the concept of snow. If you live in a place with regular snowfall, such as Essex Junction, Vermont, you know snow through direct experiences. You’ve seen it fall, touched it, shoveled it, and played in it. You recognize its texture, appearance, and even its smell. In contrast, if you live on an island like Saint...

Classification of Skeletal Muscle Fibers01:48

Classification of Skeletal Muscle Fibers

59.4K
Skeletal muscles continuously produce ATP to provide the energy that enables muscle contractions. Skeletal muscle fibers can be categorized into three types based on differences in their contraction speed and how they produce ATP, as well as physical differences related to these factors. Most human muscles contain all three muscle fiber types, albeit in varying proportions.
Slow-Twitch Muscle Fibers
Slow oxidative, muscle fibers appear red due to large numbers of capillaries and high levels of...

Muscles of the Eye01:20

Muscles of the Eye

4.0K
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 that Move the Head01:19

Muscles that Move the Head

5.7K
The muscles that move the head are a dynamic and complex group of structures that work together to facilitate a wide range of head movements, including rotation, flexion, extension, and lateral bending.
The bilateral sternocleidomastoid, or SCM, and the suprahyoid and infrahyoid muscles are significant head flexors. The SCM muscles originate at the sternum and clavicle and attach to the mastoid process of the temporal bone. The SCM contracts bilaterally to bend the head forward, whereas...

Muscles of the Abdomen01:21

Muscles of the Abdomen

3.4K
The abdominal wall encircles the abdominal cavity, providing flexible protection and shielding the internal organs from harm. It is bordered at the top by the xiphoid process and costal margins, at the back by the vertebral column, and at the bottom by the pelvic bones and inguinal ligament. The abdominal wall is divided into two regions — the anterolateral and posterior regions.
Anterolateral Region
The anterolateral region comprises five paired muscles classified into the lateral and...

Muscles that Move the Arm01:31

Muscles that Move the Arm

4.7K
Nine muscles are involved in arm movements. Two of these, the pectoralis major and latissimus dorsi, originate from the axial skeleton and are called axial muscles. The other seven originate from the scapula and are called the scapular muscles.
The pectoralis major has two origins. Its clavicular head originates on the medial half of the clavicle. In contrast, the sternocostal head originates on the costal cartilages of ribs 1-6, the sternum, and the aponeurosis of the external oblique of the...

Área de la Ciencia:

  • Ciencias de los materiales
  • Ingeniería mecánica
  • Biomimética

Sus antecedentes:

  • Los hilos de nanotubos de carbono llenos de huéspedes son músculos artificiales eficaces, pero son costosos.
  • La eficiencia de accionamiento limitada en diseños llenos de invitados restringe el rendimiento.

Objetivo del estudio:

  • Desarrollar un nuevo diseño de músculo artificial con mayor rendimiento y eficiencia.
  • Para investigar el potencial de los músculos artificiales como una alternativa superior.

Principales métodos:

  • Diseño y fabricación de músculos artificiales de funda con núcleos de hilados de bajo costo retorcidos o enrollados.
  • Evaluación del rendimiento de tracción y electroquímico bajo diversos métodos de accionamiento (electrotérmico, absorción de vapor).

Principales resultados:

  • Los músculos de la vaina demostraron una mayor capacidad de trabajo de 1,70 a 2,15 veces para aplicaciones de tracción.
  • Los músculos electroquímicos de la vaina alcanzaron un poder contráctil de 1,98 W / g, superando significativamente a los músculos humanos y alternativos.
