Which of the following musicians fits this description a virtuoso trumpeter who was one of two leading pioneers of bebop? this virtuoso was known for his consummate mastery of flute alto saxophone and bass clarinet.
Which of the following muscles of the shoulder joint is located on the posterior surface of the scapula group of answer choices?
Infraspinatus muscle originates and sits in the infraspinous fossa of the scapula. The tendon of the infraspinatus passes posteriorly on to the glenohumeral join and inserts on to the middle facet of the greater tuberosity of the humerus and capsule of the shoulder joint.
The teres minor arises from the posterior surface of the scapula, directly adjacent to the upper part of its lateral border. The upper fibers of the muscle culminate in a tendon that inserts on the greater tubercle of the humerus. The tendon blends into the capsule of the shoulder joint.
The posterior muscles include the trapezius, levator scapulae, rhomboideus, latissimus dorsi, triceps brachii, biceps brachii, serratus anterior, and deltoideus.
Trapezius is responsible for elevating the shoulder blade and rotating it during arm abduction.
These include the Trapezius, Levator Scapula, Rhomboids, Serratus Anterior, Pectoralis minor. These muscles stabilize and position the scapula.
Triceps Brachii: A muscle of the posterior compartment of the upper arm that extends the forearm.
Triceps brachii is the prime extensor of the forearm at the elbow joint. Additionally, due to its attachment on the scapula, it can also act as a weak extensor and adductor of the arm at the shoulder joint.
The rhomboid muscles are a large group of muscles in your upper back. They’re made up of the rhomboid major and the rhomboid minor. These and other muscles form the shoulder girdle that holds your shoulder blade and shoulder stable.
Where is the clavicle? The clavicle is the bone that connects the breastplate (sternum) to the shoulder. It is a very solid bone that has a slight S-shape and can be easily seen in many people. It connects to the sternum at a joint with cartilage called the sternoclavicular joint.
Anterior muscles include the pectoralis major, pectoralis minor, coracobrachialis, and the biceps brachii (Figure 1). Figure 1: The anterior muscles of the shoulder, including the pectoralis major, the underlying pectoralis minor, and the coracobrachialis, largely underlying the biceps brachii.
Figure 3. The muscles that move the humerus inferiorly generally originate from middle or lower back (e.g., latissiumus dorsi). (d) The muscles that move the humerus posteriorly are generally located on the posterior side of the body and insert into the scapula (e.g., infraspinatus).
Muscles of the Posterior Neck and the Back The posterior muscles of the neck are primarily concerned with head movements, like extension. The back muscles stabilize and move the vertebral column, and are grouped according to the lengths and direction of the fascicles.
The primary muscles involved in the action of arm abduction include the supraspinatus, deltoid, trapezius, and serratus anterior.
The deltoid muscle is the main muscle of the shoulder. It consists of three muscle heads: the anterior deltoid, lateral deltoid, and posterior deltoid.
Which of the following is a difference between the shoulder girdle and pelvic girdle? The pelvic girdle is rigid, whereas the shoulder girdle is light and capable of great mobility.
Which of the following is an efficient way to stretch the pectoralis minor muscle? Answers: By lying supine with a rolled towel directly under the thoracic spine.
Posteriorly, the spine separates the supraspinous and infraspinous fossae, and then extends laterally as the acromion. The subscapular fossa is located on the anterior surface of the scapula. The coracoid process projects anteriorly, passing inferior to the lateral end of the clavicle.
The pectoralis major, latissimus dorsi, deltoid, and rotator cuff muscles connect to the humerus and move the arm. The muscles that move the forearm are located along the humerus, which include the triceps brachii, biceps brachii, brachialis, and brachioradialis.
- Biceps brachii. Often referred to as your biceps, this muscle contains two heads that start at the front and back of your shoulder before joining together at your elbow. …
- Brachialis. This muscle lies underneath your biceps. …
- Coracobrachialis. This muscle is located near your shoulder.
The deep posterior forearm muscles are a group of five muscles located in the deep layer of the posterior compartment of the forearm. These muscles include the supinator, abductor pollicis longus, extensor pollicis brevis, extensor pollicis longus and extensor indicis.
triceps brachii is the synergist and biceps brachii is the antagonist.
- Biceps brachii: upper arm muscle enabling flexion of the arm.
- Triceps brachii: muscle in the back of the upper arm that extends the arm and fixes the elbow during fine movements.
- Brachialis: upper arm muscle beneath the biceps which flexes the elbow towards the body.
The humeroulnar articulation engages primarily in flexion and extension in the sagittal plane, with flexion to 150º and extension to 0º in the neutral position. The biceps brachii, brachialis, brachioradialis, and pronator teres all flex the elbow. The triceps brachii and anconeus serve to extend the elbow.
Muscles That Position the Pectoral Girdle The posterior muscles include the trapezius, rhomboid major, and rhomboid minor.
The scapula, or shoulder blade, is a large triangular-shaped bone that lies in the upper back. The bone is surrounded and supported by a complex system of muscles that work together to help you move your arm.
Which of the following landmarks is found on the posterior surface of the scapula? the spine of the scapula is on the back of the bone and can easily be palpated.
The scapula is a large, flat triangular bone with three processes called the acromion, spine and coracoid process . It forms the back portion of the shoulder girdle.
Your collarbone (or clavicle) is the bone that runs horizontally between the top of your breastbone (sternum ) and shoulder blade (scapula). You can feel your collarbone by touching the area between your neck and your shoulder. A broken collarbone, also called a clavicle fracture, is when this bone breaks.
The posterior chain is the muscles on your backside; hamstrings, glutes, lats, scapular retractors, and rotator cuff muscles. That means the anterior chain is the opposite; muscles that are in front of your body! These include the quads, core, and pectoral muscles.
Posterior comes from the Latin word posterus, meaning “coming after”. Posterior is often used as a technical term in biology and medicine to refer to the back side of things, and is the opposite of anterior, which refers to the front side.
The posterior compartment of the forearm is between the elbow and wrist joints, contains 12 muscles divided into superficial and deep groups (Figs. 22.1 and 22.2), and is supported by the radius and ulna (see Chapter 21).
The axial muscles include the muscles of the tail, trunk, and eyeballs as well as a group of muscles called hypobranchial muscles, which separate and migrate from the others during development.
The axial skeleton includes the bones that form the skull, laryngeal skeleton, vertebral column, and thoracic cage. The bones of the appendicular skeleton (the limbs and girdles) “append” to the axial skeleton.
- Epicranius (occipitofrontalis) …
- Frontalis (frontal belly) …
- Occipitalis muscle (occipital belly) …
- Orbicularis oculi. …
- Zygomaticus. …
- Risorius. …
- Orbicularis oris. …
The muscles that horizontally abduct your upper arm are your posterior deltoid, infraspinatus and teres minor. The muscles that horizontally adduct your upper arm are your middle deltoid, coracobrachilis, pectoralis major and latissimus dorsi.
The supraspinatus muscle originates from the supraspinous fossa of the scapula, passes under the acromion, and inserts on the superior facet of the greater tubercle of the humerus. It is responsible for the initiation of arm abduction and is in control of the motion up to the first 15 degrees of abduction.
• Horizontal adduction. (transverse flexion) – movement of humerus in a. horizontal or transverse. plane toward & across chest.
