Rectus Muscle
The Rectus muscles are a group of muscles that are part of the human anatomy. They are found in many parts of the body, including the abdomen, the chest, and the eye. These muscles are responsible for various movements and functions in the body.
Structure[edit | edit source]
The Rectus muscles are long and flat, and they run vertically down the body. They are surrounded by a sheath of connective tissue known as the Rectus sheath.
Abdominal Rectus Muscles[edit | edit source]
The Rectus abdominis muscle is the most well-known of the Rectus muscles. It is often referred to as the "six-pack" due to its appearance in physically fit individuals. This muscle is responsible for flexing the lumbar spine and it also helps in the process of breathing, coughing, and sneezing.
Chest Rectus Muscles[edit | edit source]
The Rectus thoracis muscle is a small muscle located in the chest. It is not always present in all individuals. When it is present, it assists in the movement of the chest during breathing.
Eye Rectus Muscles[edit | edit source]
The Rectus muscles of the eye include the superior rectus muscle, the inferior rectus muscle, the medial rectus muscle, and the lateral rectus muscle. These muscles control the movements of the eye.
Function[edit | edit source]
The Rectus muscles play a crucial role in various bodily functions. They are involved in movements such as flexion, extension, and rotation. They also play a role in stabilizing the body and maintaining posture.
Clinical significance[edit | edit source]
Dysfunction or injury to the Rectus muscles can lead to a variety of health issues, including abdominal hernia, strabismus, and muscle weakness. Treatment for these conditions often involves physical therapy, medication, or in some cases, surgery.
