Subscapularis Tendon Tears The subscapularis muscle is one of the four rotator cuff muscles. It is the large one at the front of the shoulder. It is the largest & strongest cuff muscle, providing 53% of total cuff strength. The upper 60% of the insertion is tendinous and the lower 40% muscle.

What Muscles Are You Working When Doing Sit-Ups? Rectus Abdominis. Situps work your rectus abdominis, a superficial layer of major abdominal muscles. A sheet of connective tissue surrounds the muscles of the rectus abdominis, creating the six-pack look, though technically there are eight muscles, not six.

subscapularis Medical Definition of subscapularis. : a large triangular muscle that fills up the subscapular fossa, that arises from the surface of the scapula, that is inserted into the lesser tubercle of the humerus, and that stabilizes the shoulder joint as part of the rotator cuff and rotates the humerus medially when the arm is held by the side of the body.

Definition/Description The supraspinatus muscle is located on the back of the shoulder. This muscle arises from the supraspinous fossa of the scapula and inserts on the greater tubercle of the humerus. The supraspinatus muscle is innervated by the nervus supraspinatus (C5-C6)5 . The supraspinatus muscle is part of the rotator cuff. The rotator cuff is a group of muscles4. It consists of the supraspinatus muscle, the infraspinatus muscle, the teres minor and the subscapularis. These muscles with their tendons stabilize, control and move the shoulder 6.

- The quadratus lumborum aids in lateral flexion of the vertebral column. The quadratus lumborum originates on the ilium and inserts on the last rib as well as lumbar vertebrae. When these muscles contract, they depress (or pull down) the ribs, and they also aid in lateral flexion of the vertebral column. Let me go back to a previous note: all of these muscles are paired.

Vastus medialis Vastus medialis. The vastus medialis muscle is a part of the quadriceps muscle group, located on the front of the thigh. It is the most medial, or inner, of the quadriceps muscles.It extends the entire length of the thigh.The portion of the muscle that is just above the knee is sometimes referred to as the vastus medialis obliquus, or VMO. This muscle is used to extend the leg at the knee and to stabilize the patella, which is also known as the kneecap.t extends the entire length of the thigh.

- The other end of the supraspinatus muscle attaches to the outside aspect of the humerus, the long bone in your upper arm. This muscle acts to lift the arm out to the side and it is one reason that it triggers pain when lifting the arm above the head (Burbank et al., 2008).

- The supraspinatus muscle is one of the musculotendinous support structures called the rotator cuff that surround and enclose the shoulder. It helps to resist the inferior gravitational forces placed across the shoulder joint due to the downward pull from the weight of the upper limb.

Subscapularis The largest and strongest muscle in this group is the subscapularis muscle. This triangle shaped muscle begins in the scapula, located on the underside of the shoulder blade, and extends up to the humerus, located on the front of the upper arm.he major arteries that run through the subscapularis muscle are the cervical artery and the subscapular artery. The subscapularis muscle is innervated by the lower and upper subscapular nerves.

The Scapula This side of the scapula is relatively unremarkable, with a concave depression over most of its surface, called the subscapular fossa. The subscapularis muscle, one of the rotator cuff muscles, originates from this side. Originating from the superolateral surface of the costal scapula is the coracoid process.

- The front of the scapula (also known as the costal or ventral surface) has a broad concavity called the subscapular fossa, to which the subscapularis muscle attaches. The medial two-thirds of the fossa have several oblique ridges, which run outward and upward.he intrinsic muscles of the scapula include the muscles of the rotator cuff-the subscapularis, teres minor, supraspinatus, and infraspinatus. These muscles attach to the surface of the scapula and are responsible for the internal and external rotation of the glenohumeral joint, along with humeral abduction.

- The orbicularis oculi muscle is one of the two major components that form the core of the eyelid, the other being the tarsal plate. The orbicularis oculi muscle is composed of skeletal muscle fibers, and receives nerves from the facial nerve.It is an important muscle in facial expression.he orbicularis oculi muscle is composed of three parts: the orbital portion, the palpebral portion, and the lacrimal portion. The orbital portion closes the eyelids firmly and is controlled by voluntary action.

Shoulder Anatomy 1 Pectoralis minor draws the scapula forward and downward, and raises the ribs in forced inspiration. 2  The subclavius muscle is a small muscle that lies deep to pectoralis major muscle. 3  It passes from rib I at the junction between the rib and its costal cartilage to a groove on the inferior (lower) surface of the clavicle. These muscles retract and elevate the scapula. 2  Teres major muscle originates from posterior surface of the inferior angle of the scapula and attaches the medial lip of the intertubercular sulcus which lies on the anterior surface of the humerus. 3  This muscle extends and medially rotates the humerus.

Orbicularis oculi The orbicularis oculi muscle lies directly underneath the surface the skin, around the eyes. Its function is to close the eyelid, and to help in the passing and draining of tears through the punctum, canaliculi, and lacrimal sac, all parts of the tear drainage system.he orbicularis oculi muscle is composed of three parts: the orbital portion, the palpebral portion, and the lacrimal portion. The orbital portion closes the eyelids firmly and is controlled by voluntary action.

Tibialis anterior The muscle inserts into the base of the first metatarsal bone in the foot, located just behind the big toe. It also inserts to the medial and inferior surfaces of the medial cuneiform tarsal. The tibialis anterior muscle helps with dorsiflexion, which is the action of pulling the foot toward the shin.It also inverts (tilts inward) the foot at the subtalar and midtarsal joints and holds up the medial longitudinal arch of the foot.n general, muscles of this compartment help to flex the foot in an upward direction at the ankle and also extend the toes. The tibialis anterior muscle emerges from the upper lateral (outer) surface of the tibia, or shinbone, and from the interosseous membrane.

Orbicularis Oris Muscle The orbicularis oris muscle is a sphincter muscle that encircles the mouth. It lies between the skin and the mucous membranes of the lips, extending upward to the nose and down to the region between the lower lip and chin. It is sometimes called the kissing muscle because it causes the lips to close and pucker. The orbicularis oris muscle is a sphincter muscle that encircles the mouth.

- The subscapularis is by far the strongest of the four rotator cuff muscles. If a client has a shoulder injury, there is a 70 percent to 85 percent chance it is the subscapularis tendon. In people under age 40, it is the most frequently injured structure in the shoulder.

Axilla The lower posterior boundary is called the posterior axillary fold and this is a compound structure consisting of the latissimus dorsi and teres major muscles.It can descend after weight loss.he axilla (or underarm, or oxter) is the area on the human body directly under the joint where the arm connects to the shoulder. It also provides the under-arm sweat gland.
