Introduction The subscapularis muscle is a large, triangular muscle located on the anterior (front) side of the scapula (shoulder blade). It is one of the four muscles in the rotator cuff that control medial rotation and shoulder joint stability. During diverse upper-limb motions, rotator cuff muscles collectively stabilize and direct the humeral head inside the…
In the dark, have you ever moved around your home without running into any furniture? Or did you gaze at your hands while typing on your keyboard? Proprioception is the mechanism that enables these everyday actions. Proprioception: What is it? Your body’s capacity to sense its position, motion, and placement in space without looking is…
Introduction The coracobrachialis muscle in the upper arm is small yet elongated. It’s situated in the arm’s anterior compartment. It starts from the scapula’s coracoid process and enters the centre of the humerus’s medial surface. Its main purpose is to flex and adduct the arm at the shoulder joint. It helps to keep the humeral…
Introduction The brachialis muscle is the elbow joint’s primary flexor. It has a fusiform shape and is positioned in the arm’s anterior (flexor) compartment, close to the biceps brachii. It is periodically divided into two portions and may combine with fibres from the biceps brachii, coracobrachialis, or pronator teres muscles. Structure Origin The distal part…
What is a Lumbar Extension? Lumbar extension is the bending backward of the spine, focusing on the lower back (lumbar) area. It often involves exercises that arch the back in a controlled manner to strengthen muscles, increase flexibility, and support the spine. It helps strengthen the lower back muscles, improve posture, and relieve pressure on…
Introduction The serratus posterior superior muscle is found in the back’s intermediate compartment. It has a slender, rectangular shape and is placed deep in the upper back, close to the rhomboid muscles. The rib cage is raised by the serratus posterior superior muscle and lowered by the serratus posterior inferior muscle. When forced breathing is…
Introduction The serratus posterior inferior muscle is found in the back’s intermediate compartment. It is located in the lower part of the back, beneath the latissimus dorsi. It plays a role in respiration and stabilization of the lower thoracic and upper lumbar vertebrae. Structure The muscle is placed where the thoracic and lumbar spines meet….
What is Cervical Lateral Flexion? The cervical spine or neck may move on either side to tilt the head toward the shoulder. The term “cervical lateral flexion” describes this movement. To put it briefly, it is a lateral neck bend that does not include head rotation but rather puts the ear closer to the shoulder….
What is a Lumbar Flexion? Lumbar Flexion refers to the forward bending movement of the lower spine, where the angle between the spine and the pelvis decreases. This motion is commonly used in daily activities like bending to tie shoes and is essential for overall spinal mobility and flexibility. What is Lumbar Flexion And Extension?…
What are Mitochondria? The majority of eukaryotic creatures have mitochondria, which are organelles that are frequently referred to as the “powerhouses of the cell.” Their main work is to use a process known as cellular respiration to create adenosine triphosphate (ATP), which is the source of energy. This article will examine mitochondria’s functions, appearance, and…
