Introduction The forearm is a vital anatomical region located between the elbow and the wrist. It contains a complex network of muscles that contribute to the intricate movements of the hand, wrist, and fingers. These muscles can be broadly classified into anterior (flexor) muscles and posterior (extensor) muscles. The anterior muscles facilitate actions such as…
Introduction The Serratus posterior muscles are a pair of muscles located in the upper back and chest region of the human body. These muscles are divided into two groups: the serratus posterior superior and the serratus posterior inferior. The upper and lower backs each include a pair of serratus posterior muscles. The serratus posterior superior…
Introduction The Quadratus lumborum muscle is a posterior abdominal wall muscle located deep within the belly and dorsal to the iliopsoas. It is the deepest muscle of the posterior abdominal wall and is frequently misidentified as a back muscle. It has an irregular shape, although it is often quadrangular, which is why it is called…
Anatomy of Diaphragm Muscle The Diaphragm muscle is the primary muscle utilized in respiration, which is the action of breathing. This dome-shaped muscle is found just below the lungs and heart. It also contracts continually as breathes in and out. The diaphragm muscle is a thin skeletal muscle that seats at the base of the…
Introduction The Multifidus muscle is a group of short, triangular muscles that along with the semispinalis and rotatores include the transversospinal group of deep back muscles. They are the thickest muscles in the transversospinal group and are shorter than semispinalis, but lengthier than rotatores. The Multifidus muscles are located on either side of the vertebral…
Introduction Obliquus capitis superior, or superior oblique muscle, is a small paired muscle found deep in the upper cervical region, at the base of the occipital bone. It is one of four muscles that incorporate the suboccipital muscles group along with rectus capitis posterior major, rectus capitis posterior minor and obliquus capitis inferior muscles. Obliquus…
Introduction Rectus capitis anterior muscle is one of the deep neck muscles whose role is to flex the head on the neck at the atlantooccipital joint. The rectus capitis anterior muscle is a flat, small muscle that is nestled behind the upper portion of the longus capitis muscle. This short strap muscles belong to the…
Introduction Rectus capitis lateralis muscle is a small, paired muscle that is seen within the neck, deep to the prevertebral portion of the deep cervical fascia. It is a portion of the prevertebral muscle group along with also splenius capitis, levator scapulae, and middle and posterior scalene muscles. The rectus capitis lateralis consists of paired…
Introduction The human tongue is an organ that helps the process of digestion by facilitating the manipulation and movement of food particles during mastication and swallowing. The tongue is also essential in the exhibition of speech and essential for employing the sense of taste. The styloglossus muscles are paired with the extrinsic muscle of the…
Introduction Longus capitis muscle is a deep anterior neck muscle that drives in front of the cervical spine. Together with rectus capitis anterior muscle, rectus capitis lateralis muscle, longus cervicis muscle, and anterior scalene muscle, it produces the prevertebral layer of neck muscles. These muscles are also wrapped up in the prevertebral layer of the…
