Serratus anterior muscle

pharmacologic pain relief methods(3). Pecs1 and 2 can provide effective postoperative analgesia for such procedures (4). They are field blocks that aim to deposit the local anesthetic between the pectoralis major and minor muscles and between pectoralis minor and serratus anterior respectively to block the different peripheral nerves supplying the

The air flow will control how quickly the diaphragm goes up. The rebounding (equilibrium) forces also activated when lung-thorax unit is compressed. Their needs to be a maintained airflow and subglottal pressure. Use inspiratory muscles to control air flow coming out at first. Still contracts the diaphragm and controls how quickly it goes up. Still contracts the external intercostals and others to control rib cage. Going down slower and volume decreases much slower. Positive pressure

On the first day of our dissection process, the group before us also had the right portion of the back, which includes the following muscles: Trapezius, Latissimus dorsi, Triangle of auscultation, Lumbar triangle, Blood vessels and nerves, posterior triangle of neck, Rhomboid major, Rhomboid minor, Levator scapulae, Serratus posterior superior and inferior, Splenius capitis, Semispinalis, erector spinae, and Multifidus. Once it was our turn for the dissection process of the cadaver, the previous

had a 3-month history of deep aching pain in the antero-lateral right leg and on some occasions, bilaterally (1). The pain occurs within 15 to 20 minutes of her training regime or upon commencing a run. She reported symptoms of tightness in her anterior leg, and weakness of ankle dorsi-flexors (1). She described that symptoms worsened as the exercise duration was prolonged. When activity ceased, symptoms were alleviated, though pain would return if she re-engaged in the activity. Upon attempting

The Anterior Thoracic Nerves 1 is part of the thoracic region in the spinal nerve that originates thoracic vertebrae 1 (T1). When T1 is not functional and there is limited activity in the upper extremity, it causes a debilitating condition called scapular winging. The muscles affected are serratus anterior, trapezius, and rhomboids. Loss of function of the Anterior Thoracic Nerves 1 would affect the antagonist muscles of Shoulder Medial Rotation (Serratus anterior, Trapezius, and Rhomboids), not

The consequences of weak muscles around the scapula affect your arm movements and strength as well as your posture. The scapula is important for a variety of movements of the arm by moving the glenoid fossa into the best position for the head of the humerus. Elevating the scapula uses your levator scapulae, rhomboids, and trapezius 1 and 2 muscles. Elevation of the scapula allows you to shrug and lift your shoulders up. If the muscles needed for elevating your scapula are weak, then your shoulders

Thoracic muscles involved in forced expiration include the interosseous portion of the internal intercostals, innermost intercostals, transversus thoracis, subcostals, and serratus posterior inferior. The function of the interosseous portion of the internal intercostals and the innermost intercostals is to depress ribs 1-11. The transversus thoracis

Introduction The shoulder is one of the largest and most complex joints in the human body(1)The shoulder is not a single joint; it is an intricate arrangement of bones, muscles and ligaments, which provides strength and range of motion to the arm(1, 2). Shoulder pain accounts for between 16-21% of all musculoskeletal complaints(3, 4). There are many causes of shoulder pain such as: repetitive movements and overuse, trauma, and degenerative changes. Shoulder pain and associated glenohumeral

CERVICAL VERTEBRAE (7) – Trapezius (middle) Smallest of the true vertebrae, cervical vertebrae are found just below the skull. Trapezius is a large muscles, spanning the neck, shoulders and back. CLAVICLE – Clavicular Pectoralis Major Also commonly known as the collar bone, the clavicle is the only long bone in the body that is horizontal, connecting scapula to sternum. Because of its position, the clavicular pectoralis major is commonly referred to as the “upper chest”. CRANIUM – Trapezius (upper)

trapezius muscle: - Origin: it has an extensive origin from the base of the skull to the upper lumbar vertebrae. - Insertion: it inserts on the lateral aspect of the clavicle, acromion, and scapular spine. - Nerve supply: It is innervated by the spinal accessory nerve. - Action: It functions mainly as a scapular retractor and elevator of the lateral angle of the scapula[19]. The rhomboids muscles: The rhomboids, consisting of the major and minor muscles. - Origin: the major and minor muscles originate
