Serratus Anterior Muscle: Action, Origin & Innervation

  1. The serratus anterior is a fan shaped muscle, which structurally may be divided into 3 sets of fibers. The first set of fibers (1st serration) insert into the superior angle of the scapula, originating on the first rib and occasionally the second (23)
  2. Serratus anterior muscle arises from the anterolateral chest wall as eight interdigitations of muscle that run posteriorly around the chest wall, under the scapula to insert onto the medial scapula. It is considered one of the four muscles of the pectoral region
  3. Serratus posterior inferior is innervated by the anterior rami of the T9-T11 spinal nerves, as well as the subcostal nerves (T12). Blood supply Both muscles receive their vascular supply from the posterior intercostal arteries

Serratus Anterior Muscle: Function, Origins - Human

Purpose of the study: The serratus anterior, innervated by the long thoracic nerve, participates in shoulder abduction and elevation, stabilizing the scapula on the rib cage. Paralysis of the serratus anterior prohibits shoulder abduction and elevation beyond 90 degrees and elevation of the spinal border of the scapula Educational Video created by Dr. Sanjoy Sanyal; Professor, Department Chair, Surgeon, Neuroscientist and Medical Informatician in the Western Hemisphere.It s.. Three‐dimensional studies have shown that the serratus anterior contributes to all components of 3‐D scapular movements during arm elevation, which includes upward rotation, posterior tilt, and external rotation. If this muscle is not functioning properly, shoulder abduction will decrease and impingement occurs

Parasympathetic Points it up Sympathetic Shoots it out. Innervation of penis. S2, 3, 4 keep the penis off the floor refers to the innervation of the penis by branches of the pudendal nerve.
  2. The muscle is situated at the junction of the thoracic and lumbar regions. It has an irregularly quadrilateral form, broader than the serratus posterior superior muscle, and separated from it by a wide interval. It arises by a thin aponeurosis from the spinous processes of the lower two thoracic and upper two or three lumbar vertebrae
  3. Serratus Anterior Contraction. When the serratus magnus contracts it protracts and upwardly rotates the shoulder girdle at acromioclavicular and sternoclavicular joints and stabilizes the scapula against the thoracic wall. Due to its involvement in a punching motion, the serratus anterior is the boxer's muscle

A further modification is the serratus plane nerve block, in which local anesthetic is injected between the serratus anterior and latissimus dorsi muscles. These interfascial injections were developed as alternatives to thoracic epidural, paravertebral, intercostal, and intrapleural nerve blocks, primarily for analgesia after surgery on the. Der Musculus serratus anterior ist durch den Nervus thoracicus longus (langer Brustnerv), ein Zweig des Plexus brachialis innerviert. Der lange Brustnerv verläuft auf der Innenfläche des Musculus serratus anterior Serratus Anterior Exercise #3:Scap Pushups. I'm sure you've trained pushups before and this is similar, except we're focusing on pure scapular movement without movement at the glenohumeral joint or elbow. The Scap Pushup is a simple dynamic exercise to activate the serratus anterior. 4 Point Scapular Pushup The serratus posterior inferior is innervated by the intercostal nerves (9th through 12th) Serratus Anterior: The Serratus Anterior muscle is utilized in activities which draw the scapula forwards. It is utilized vigorously in push-ups and bench presses. Winged scapula is a designator having a weak Serratus Anterior muscle.

Serratus Posterior Muscles: Innervation. The serratus posterior muscles are innervated by several nerves from the ventral rami. The ventral rami are the nerves that make up the anterior divisions. The serratus anterior is often called the boxer's muscle as it is responsible for protraction of the scapula - a movement which occurs when throwing a punch. Origin: fleshy slips from lateral parts of 1 st to 8 th ribs. Insertion: Medial margin of scapula on anterior surface. Innervation: Long thoracic nerve Serratus anterior muscle is one of the four muscles of the pectoral region.

Serratus Anterior Muscle: Anatomy, Function, and Treatmen

The Origin, Insertion, Nerve Supply, Action of Serratus

The serratus anterior muscle is essential for normal shoulder motion. It helps to move the shoulder blade and stabilizes it during shoulder motions. Injury to the long thoracic nerve causes a condition called scapular winging. This occurs when the serratus anterior muscle becomes weakened or paralyzed after injury These muscles receive innervation and blood supply from corresponding intercostal nerves (thoracic anterior rami), arteries, and veins (Fig. 6). Figure 6 : Anterior thoracic wall musculature. Cadaveric specimens. (Pectoralis major, pectoralis minor, and serratus anterior muscles reflected bilaterally in B. 1 The intercostal nerve runs between the innermost intercostal and internal intercostal, it then diverts through serratus anterior with cutaneous innervation of the lateral thorax. Sympathetic and muscular innervation is also derived from the thoracic roots, with the exception of the shoulder girdle muscles (pectoralis, latissimus dorsi and.
