Muscles of the Abdomen01:21

Muscles of the Abdomen

4.6K
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...

Muscles of the Vertebral Column01:27

Muscles of the Vertebral Column

5.3K
The back muscles that lie deep into the thoracolumbar fascia are called intrinsic or true back muscles. These muscles are divided into four layers: superficial, intermediate, deep, and deepest layers.
Superficial Layer:
The superficial layer consists primarily of the splenius muscles, which include the splenius capitis and splenius cervicis. These muscles are mainly responsible for the head and cervical spine movements, including extension, rotation, and lateral bending. The splenius capitis...

Muscles of the Thorax01:25

Muscles of the Thorax

4.5K
The thorax muscles are central to the body's respiration and provide essential support and movement for the upper body. They are intricately designed to facilitate the complex breathing process while also contributing to the structural integrity and mobility of the chest and upper limbs.
The diaphragm is at the core of thoracic musculature, the primary muscle involved in breathing. This expansive, dome-shaped muscle marks the division between the thoracic and abdominal cavities. It...

Muscles of the Shoulder01:23

Muscles of the Shoulder

9.3K
The muscles surrounding the shoulder girdle, including the clavicle and scapula, primarily stabilize the scapula. This stable base allows other muscles to move the humerus effectively. Scapular movements often mirror those of the humerus and extend its range of motion. For instance, raising the arm above the head would not be feasible without simultaneous upward rotation of the scapula.
Anterior Thoracic Muscles
The anterior thoracic muscles include the serratus anterior, subclavius, and...

Axial and Appendicular Muscles01:18

Axial and Appendicular Muscles

3.5K
Skeletal muscles, the key players in our body's movement, can be classified into two groups based on their location and function: axial muscles and appendicular muscles. These classifications reflect the primary roles the muscles play in the body's structure and movement.
Axial Muscles
Axial muscles, situated along the body's midline, are intricately connected to the axial skeleton, which includes the skull, spine, ribs, and sternum. These muscles facilitate facial expressions and...

Mechanism of Breathing III: The Accessory Muscles01:21

Mechanism of Breathing III: The Accessory Muscles

5.3K
The Role of Accessory Muscles in the Respiratory System
The respiratory system is a complex network that relies on primary respiratory muscles like the diaphragm, but also involves accessory muscles to enhance lung expansion and airflow during both inhalation and exhalation.
Enhancing Inhalation with Accessory Muscles:
Accessory muscles such as the sternocleidomastoid, scalene, intercostal, and abdominal muscles are crucial when additional respiratory effort is required, such as during deep...

    Area of Science:

    • Biomechanics
    • Exercise Physiology
    • Human Movement Science

    Background:

    • Maximum expiration may enhance deep and superficial abdominal muscle coactivation during challenging exercises.
    • Limited research exists on the impact of maximum expiration on abdominal muscle activity during lumbar stabilization exercises.

    Purpose of the Study:

    • To quantify the changes in abdominal muscle activity during side bridge exercise when combined with maximum expiration.

    Main Methods:

    • Electromyography (EMG) measured the activity of rectus abdominis (RA), external oblique (EO), and internal oblique (IO) muscles.
    • Twelve healthy men performed three tasks: breath-holding after maximum expiration (supine), breath-holding after resting expiration (side bridge), and breath-holding after maximum expiration (side bridge).

    Main Results:

    • Maximum expiration significantly increased the activity of the RA, EO, and IO muscles compared to resting expiration during side bridge exercise (P <0.05).

    Conclusions:

    • This study is the first to show the effect of maximum expiration on abdominal muscle activity during stabilizing exercises.
    • Findings contribute to the understanding of therapeutic exercise for alternative core training strategies.
