Rectus Abdominis Muscle This lumpy appearance results in the rectus abdominis muscles being referred to as the “six-pack.”. The name rectus abdominis comes from the Latin words for “straight” and “abdominal,” indicating that its fibers run in a straight vertical line through the abdominal region of the body....

Movement and Muscles at the Trunk lateral flexion The muscles that laterally flex your trunk are the same as those that flex it forward, just in different combinations. If you contract the right side of your rectus abdominis and your right external and internal obliques, then you flex to the right.If you contract the left side of your rectus abdominis and your left external and internal obliques, then you flex to the left.f you contract the right side of your rectus abdominis and your right external and internal obliques, then you flex to the right. If you contract the left side of your rectus abdominis and your left external and internal obliques, then you flex to the left.

- Three are flat, the external oblique, the internal oblique and the transversus abdominis, and one is a straplike muscle, the rectus abdominis. The fibers in each of these muscles run in a cross direction from one another in a way that maximizes the strength of the three muscles together (think of plywood).

Rectus Diastasis (Abdominal separation) Rectus Diastasis. Rectus diastasis, or diastasis recti, is a condition where the rectus abdominis muscles are no longer located next to each other as they run up and down the abdomen from the breastbone (xyphoid) to the pubic bone (symphysis pubis).The word “diastasis” comes from the Greek word meaning “to separate”.ectus diastasis, or diastasis recti, is a condition where the rectus abdominis muscles are no longer located next to each other as they run up and down the abdomen from the breastbone (xyphoid) to the pubic bone (symphysis pubis).

- A muscle may be given a name based on the direction of muscle fibers, or the muscle as a whole, relative to the longitudinal axis of the muscle, or body part with which the muscle is associated. The term rectus implies that the fibers or muscle is oriented straight with respect to the longitudinal axis.

Rectus abdominis muscle The rectus abdominis muscle is contained in the rectus sheath, which consists of the aponeuroses of the lateral abdominal muscles. Three bands of connective tissue called the tendinous intersections traverse the rectus abdominus, which separates this parallel muscle into eight distinct muscle bellies.

- The lateral rectus muscle is innervated by CN VI (abducens nerve). Remember LR6 SO4 the rest 3. (Lateral rectus innervated by CN VI, Superior oblique innervated by CN IV, the rest of the eye muscles are controlled by CN III)

muscle This is in contrast with the oblique eye muscles, which have an angular approach to the eyeball. Superior Rectus. 1  Attachments: Originates from the superior part of the common tendinous ring, and attaches to the superior and anterior aspect of the sclera. 2  Actions: Main movement is elevation.here are seven extraocular muscles – the levator palpebrae superioris, superior rectus, inferior rectus, medial rectus, lateral rectus, inferior oblique and superior oblique. Functionally, they can be divided into two groups:

Gait Analysis The rectus femoris is active electrically for only a brief period corresponding with preswing and initial swing. Although this muscle crosses and extends the knee, its role in gait is to assist in flexion at the hip as swing commences.

Rectus Abdominis 1 Flexes the spine. 2  This means that the rectus abdominis muscle bends the spine to the front (i.e. it moves the sternum down and forward towards the pelvis). 3  Compresses the abdominal cavity.

Axial Muscles: Trunk Muscles Anatomy & Support These sits-ups, along with other similar exercises, work our oblique (that is, not straight) as well as our rectus (or straight) muscles located in the body wall of our trunk. These oblique and rectus muscles are axial muscles as they're located in the middle, or the axis, of the body. Most people will think of trunk muscles as being located anteriorly (that is, in the front) in the belly area of the abdomen.

- The rectus abdominis and transversus abdominis contract continually while you perform push-ups, to hold your body off the floor and keep your legs and torso aligned. The rectus abdominis spans the front of your abdomen and is the most prominent of the abdominal muscles.

Muscles of the Eye The two oblique muscles of the eye are responsible for the rotation of the eye and assist the rectus muscles in their movements. The superior oblique muscle rotates the eye medially and abducts it when the eye if facing forward while the inferior oblique rotates the eye laterally and adducts it.

The Extraocular Muscles Look again at the graphic of the right eye in the section above. If the superior rectus (SR) muscle of the eye were to be contracted with no other muscles in play, it can be visualized how the front of the eye would be pulled upward (supraduction or elevation) and inward (adduction), toward the top of the nose.he cardinal positions are six positions of gaze which allow comparisons of the horizontal, vertical, and diagonal ocular movements produced by the six extraocular muscles when both eyes and multiple muscles are working together.

Rectus Femoris Rectus Femoris Origin. This muscle has two origins – anterior and posterior. The anterior origin is from the bottom of the spine while the posterior one is at the Acetabulum (the cup-shaped hollow space in the hipbone where the tip of the femur fits in to form a ball-and-socket joint).

Muscles of the Eye Unique among the muscles of the eye, the inferior oblique muscle arises from the maxilla on the medial floor of the orbit and inserts at an oblique angle on the inferior surface of the eye. Physiology. The four rectus muscles of the eye control the movement of the eye in the cardinal directions. They work against each other to control the movements of the eye in various directions. The first of these muscles, the superior rectus muscle, elevates the eye, allowing the eye to look up.

Range of Movement (ROM) The Three Axis. Frontal Axis-passes from side to side at right angles to the sagittal plane. Sagittal or Transverse Axis-passes horizontally from front to rear lying at right angles to the frontal plane. Longitudinal or Vertical Axis-passes from head to foot at right angles to the transverse plane.

Rectus abdominis muscle The rectus abdominis muscle, also known as the  abdominals or abs , is a paired muscle running vertically on each side of the anterior wall of the human abdomen, as well as that of some other mammals. There are two parallel muscles, separated by a midline band of connective tissue called the linea alba.

Diastasis recti Diastasis recti (also known as abdominal separation) is commonly defined as a gap of roughly 2.7 cm or greater between the two sides of the rectus abdominis muscle.This condition has no associated morbidity or mortality.easurement of the width of separation is determined by the number of fingertips that can fit within the space between the left and right rectus abdominis muscles. Separation consisting of a width of 2 fingertips (approximately 1 1/2 centimeters) or more is the determining factor for diagnosing diastasis recti.

Eye movement (sensory) Eye movement of inferior oblique muscle, superior view. Anterior view. The muscles are supplied by the oculomotor nerve, with the exception of the superior oblique, which is supplied by the trochlear nerve, and the lateral rectus, supplied by the abducens nerve.
