What does rectus and oblique mean?

2018 Within your core, this push-up variation specifically targets your obliques (the muscles on the side of your abdomen) as well as your rectus abdominis (aka, your abs, the muscles that run vertically on your abdomen). —

What are the two oblique muscles?

These are the superior rectus, lateral rectus, inferior rectus, medial rectus, superior oblique and inferior oblique muscles. Located within the orbit, they surround the eyeball completely, facilitating its movement in various directions….Superior oblique muscle.

Origin Body of the sphenoid bone
Blood supply Ophthalmic artery

What is the function of the inferior rectus muscle?

The inferior rectus has a primary action of depressing the eye, causing the cornea and pupil to move inferiorly. The inferior rectus originates from the Annulus of Zinn and courses anteriorly and laterally along the orbital floor, making an angle of 23 degrees with the visual axis.

What are the six muscles that control eye movement?

The Six Muscles of the Eye

  • Lateral Rectus. The lateral rectus is a muscle of the eye’s orbit.
  • Medial Rectus. The medial rectus is also a muscle of the eye’s orbit.
  • Inferior Rectus. The inferior rectus is also a muscle of the orbit.
  • Superior Rectus.
  • Superior Oblique.
  • Inferior Oblique.

What is the rectus?

The rectus abdominis muscle, also known as the “abdominal muscle” or simply the “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.

What does oblique mean in muscles?

Filters. A flat muscle that forms the outer layer on each side of the abdominal wall; external oblique.

What is superior rectus?

The superior rectus has a primary action of elevating the eye, causing the cornea to move superiorly. The superior rectus originates from the annulus of Zinn and courses anteriorly and superiorly over the globe, making an angle of 23 degrees with the visual axis.

What is the medial rectus?

The medial rectus is an adductor, and functions along with the lateral rectus which abducts the eye. These two muscles allow the eyes to move from side to side.

What is inferior oblique?

The inferior oblique is the only extraocular muscle to have its anatomic origin in the anterior orbit. The muscle runs from the medial corner of the orbit to the lateral aspect of the globe, its length approximately paralleling the tendon of insertion of the superior oblique muscle.

What is the function of superior rectus?

What is inferior oblique muscle?

Is the lateral rectus muscle horizontal or vertical?

Along with the medial rectus, the lateral rectus forms the horizontal rectus muscle whereas superior and inferior rectus muscles form the vertical rectus muscles.

What is the difference between the recti and oblique eye muscles?

Unlike the recti muscles, the oblique muscles do not attach directly to the eye via the common tendinous ring. Instead, oblique muscles attach angularly to the eye and have separate origins. The superior oblique eye muscle originates from the sphenoid bone, which is one of the seven bones that make up the eye socket.

What is the internal oblique muscle?

Internal Oblique: This muscle lies under the external oblique. This muscle starts on your iliac crest    (the top edge of your pelvis ) and inserts on the rectus sheath, which is basically the “container” or sheath, that holds your rectus abdominus muscle that runs up the center of your body.

What are the different types of recti muscles?

Recti muscles 1 Superior rectus muscle. The superior rectus muscle is found at the top of the eye and controls upward movement of the eye. 2 Medial rectus muscle. The medial rectus eye muscle attaches to the side of the eye closest to the nose and moves the eye inward. 3 Lateral rectus muscle. 4 Inferior rectus muscle.

What is the difference between the superior and inferior oblique?

Every eye muscle does multiple jobs, so the superior oblique does contribute to other motions. The inferior oblique has a similar job to the inferior rectus, but it is the muscle that moves the eye upward when the eye is looking in toward the nose, rather than away.
