Overview of Muscle Tissues

22.7K
The human body has three types of muscle tissue: skeletal, smooth, and cardiac. Each class has unique properties that enable them to perform specific functions. However, all muscle tissues share certain properties, including elasticity, contractility, and excitability. 
Elasticity
Elasticity is the ability of muscles to stretch and return to their original shape. This property is partly due to elastic fibers — macromolecules that run through the muscles. These fibers are firm and...

Tissues

85.7K
Cells with similar structure and function are grouped into tissues. A group of tissues with a specialized function is called an organ. There are four main types of tissue in vertebrates: epithelial, connective, muscle, and nervous.

Classification of Skeletal Muscle Fibers01:48

Classification of Skeletal Muscle Fibers

59.6K
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

4.5K
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

6.1K
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

3.6K
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...

Summary

Actinomyosin-mediated elasticity regulates the thermogenic capacity of UCP1+ adipocytes. This finding offers new strategies for stimulating UCP1-dependent thermogenesis in brown and beige fat cells.

Area of Science:

  • Cellular Biology
  • Metabolism
  • Physiology

Background:

  • Brown and beige adipocytes are key players in thermogenesis.

Purpose of the Study:

  • To investigate novel regulatory mechanisms of UCP1-dependent thermogenesis.
  • To explore the role of cellular mechanics in adipocyte thermogenic capacity.

Main Methods:

  • Analysis of actinomyosin-mediated elasticity in adipocytes.
  • Assessment of thermogenic capacity in relation to cellular elasticity.

Main Results:

  • Actinomyosin-mediated elasticity was demonstrated to regulate the thermogenic capacity of UCP1+ adipocytes.
