Suboccipital muscles The suboccipital muscles are a group of muscles defined by their location to the occiput.Suboccipital muscles are located below the occipital bone. These are four paired muscles on the underside of the occipital bone; the two straight muscles (rectus) and the two oblique muscles (obliquus). The muscles are named.1  Rectus capitis posterior major goes from the spinous process of the axis (C2) to the occipital bone.2  Rectus capitis posterior minor goes from the middle of the posterior arch of the atlas to the occipit. Rectus capitis posterior major goes from the spinous process of the axis (C2) to the occipital bone. 2  Rectus capitis posterior minor goes from the middle of the posterior arch of the atlas to the occipit. 3  Obliquus capitis superior goes from the transverse process of the atlas to the occiput.

The Subscapularis is 1 of the 4 rotator cuff muscles, that together have a role of keeping the head of the Humerus within the Glenoid Cavity. The Subscapularis is actually the LARGEST and most POWERFUL of the 4 rotator cuff (Keating JF, JBJB, BR.. 1993). This muscle originates on the subscapular fossa of the scapula and inserts onto the lesser tuberosity of the humerus, which creates movement at the shoulder/gleno-humeral joint into internal rotation and horizontal adduction.

- Pectoralis Major. This a large, fan shaped muscle, and is the most superficial muscle in the pectoral region. It also makes up most of the anterior wall of the axilla. The muscle has two heads – a clavicular head (attaches to the clavicle), and a sternocostal head (attaches to the sternum and ribs).he pectoralis minor muscle is much smaller than the pectoralis major, and lies posterior (underneath) to it. With the pectoralis major, it forms part of the anterior wall of the axilla. The muscle has a triangular shape, originating from the anterior surfaces of ribs 3 – 5.

Serratus posterior muscles The serratus posterior muscles are two thin, superficial back muscles which lie above the intrinsic back musculature. Both originate from the spinous processes and attach on the ribs, which is why they are also referred to as spinocostal muscles.

The Rotator Cuff - S.I.T.S Muscles The subscapularis muscle works to depress the head of the humerus allowing it to move freely in the glenohumeral joint during elevation of the arm. It also works with the other rotator cuff muscles to stabilize the head of the humerus in the glenohumeral joint, or shoulder joint. Infraspinatus: The infraspinatus muscle originates below the spine of the scapula, in the infraspinatus fossa, and it inserts on the posterior aspect of the greater tuberosity of the humerus.

The Infrahyoid Muscles The infrahyoid muscles are a group of four muscles that are located inferiorly to the hyoid bone in the neck. They can be divided into two groups: Superficial plane – omohyoid and sternohyoid muscles. Deep plane – sternothyroid and thyrohyoid muscles.

Supraspinatus muscle The supraspinatus (plural supraspinati, from Latin supraspinatus) is a relatively small muscle of the upper back that runs from the supraspinatous fossa superior of the scapula (shoulder blade) to the greater tubercle of the humerus. It is one of the four rotator cuff muscles and also abducts the arm at the shoulder.

- The occipital bone forms the floor and the back wall of the skull. Where it joints the parietal bones anteriorly it forms the lambdoid suture. At the base of the occipital bone there is a large opening called the foramen magnum where the brain joins the spinal cord.

- That being said, the prime mover responsible for scapular depression is the trapezius (specifically the lower fibers). Other muscles which act as stabilizers or synergists in scapular depression and eventual scapular protraction are the subscapularis, the serratus anterior and the lower fibers of latissimus dorsi.hat being said, the prime mover responsible for scapular depression is the trapezius (specifically the lower fibers).

- Muscles of the neck. NECK MUSCLES: The motion of the neck can be divided into rotation (looking side to side), lateral flexion (ear to shoulder), flexion (chin to sternum) and hyperextension (looking up). Knowing which muscles do each motion will take you a long way towards proper evaluation and treatment.nother common neck problem is limited rotation, which involves the levator scapula, the suboccipitals, or the deep neck muscles. ASSESSMENT: Neck evaluation includes passive range of motion in the various directions, looking for restriction and pain.

Subscapularis Muscle: Action, Origin & Insertion The subscapularis originates from the subscapular fossa, which is the triangular-shaped, concave surface at the front of the scapula. From the subscapular fossa, this muscle extends outward and inserts onto the lesser tubercle of the humerus. The humerus is the long bone of the upper arm, and the lesser tubercle (also known as the lesser tuberosity) is the round prominence located on the top, front portion of the humerus.

Occipitofrontalis muscle The occipitofrontalis muscle (epicranius muscle) is a muscle which covers parts of the skull. It consists of two parts or bellies: The occipital belly, near the occipital bone, and the frontal belly, near the frontal bone. In humans, the occipitofrontalis only serves for facial expressions.

The Posterior Triangle of the Neck Muscles. The posterior triangle of the neck contains many muscles, which make up the borders and the floor of the area. A significant muscle in the posterior triangle region in the omohyoid muscle. It is split into two bellies by a tendon.he omohyoid muscle splits the posterior triangle of the neck into two; a superior and inferior part. The superior part is larger, and is called the occipital triangle. The occipital triangle is crossed by the accessory nerve. The inferior triangle is known as the subclavian triangle.

- 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.

Chapter 11 A&P Deep to the vessels and nerves in the superficial fascia of the scalp is a thin fibromuscular sheet known as the occipitofrontalis muscle. It is one of the muscles of facial expression innervated by cranial nerve (CN) VII (aka facial nerve). The portion over the forehead is called the frontalis muscle (frontal belly of the occipitofrontalis), and that over the back of the head is called the occipitalis muscle (occipital belly of the occipitofrontalis).

Bicipital aponeurosis The bicipital aponeurosis (also known as lacertus fibrosus) is a broad aponeurosis of the biceps brachii which is located in the cubital fossa of the elbow and separates superficial from deep structures in much of the fossa. The bicipital aponeurosis originates from the distal insertion of the biceps brachii.While the tendon of the biceps inserts on the radial tuberosity, the aponeurosis reinforces the cubital fossa, and helps to protect the brachial artery and the median nerve running underneath.This protection is important during venipuncture (taking blood) from the median cubital vein.ome individuals (about 3% of the population) have a superficial ulnar artery that runs superficially to the bicipital aponeurosis instead of underneath it. These individuals are at risk for accidental injury to the ulnar artery during venipuncture.
