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…
What are Plantar interossei muscles? The plantar interossei are a group of three small muscles in the sole’s middle area. Plantar interossei can be categorized in two ways, as the foot muscles can be divided into three groups from lateral to medial or four layers from superficial to deep: Together with the flexor digitorum brevis,…
What is the Pyramidalis muscle? The pyramidalis is a pair of triangular muscles on either side of the linea alba in the anterior abdominal wall. The pyramidalis muscle, along with the rectus abdominis muscle, is included in the anterior abdominal muscles according to the narrowest anatomical classification. However, when the functional anatomy of the body…
What is the Transversus abdominis muscle? The transversus abdominis (TVA) muscle is one of the key muscles in the core region of the body. It is a deep muscle layer located beneath the obliques and rectus abdominis muscles. The TVA is named for its orientation, as its muscle fibers run horizontally across the abdomen. The…
What is the Internal abdominal oblique muscle? The internal abdominal oblique muscle, also known as the internal oblique muscle, is one of the muscles that make up the anterolateral abdominal wall. It is located deep to the external abdominal oblique muscle and superficial to the transverse abdominal muscle. The internal oblique muscle is paired and…
What is the External abdominal oblique muscle? The external abdominal oblique muscle is one of the four muscles that make up the abdominal wall. It is located on the lateral sides of the abdomen and is the largest and most superficial of the three flat abdominal muscles. The external abdominal oblique is a paired muscle…
What is the Rectus abdominis muscle? The rectus abdominis muscle, commonly known as the “abs” or “six-pack,” is a paired muscle located in the anterior (front) part of the abdomen. It is a long, strap-like muscle that extends vertically from the pubic bone to the lower ribs. The rectus abdominis is enclosed by a layer…
What is the Flexor digiti minimi brevis of the foot? The flexor digiti minimi brevis of the foot is a small muscle located in the sole of the foot. It is one of the intrinsic muscles of the foot and plays a role in flexion and stabilization of the fifth (little) toe. This muscle can…
What is Adductor hallucis muscle? The adductor hallucis muscle is an intrinsic muscle, which has two heads. The adductor hallucis muscle is functionally a member of the medial group of plantar foot muscles, which are divided into three vertical groups: lateral, central, and medial. Nevertheless, it is anatomically situated within the foot’s central compartment. Additionally,…
What is Flexor hallucis brevis muscle? The flexor hallucis brevis is a small muscle located in the foot, found deep within the sole, on the medial part. It is part of the intrinsic muscles of the foot, which are responsible for controlling the movement and stability of the foot. Originating from the cuboid bone and…
