A comparison of forelimb and pectoral girdle muscle morphology between pterosaurs, birds, and bats (ventral view). (A) Reconstruction of the forelimb and pectoral girdle muscles of a pterosaur, Anhanguera sp. Based on Bennett (, ). The ligamentum extensor digiti alae is omitted in this illustration. Embryology. The development of the muscles of the pectoral girdle and upper limb bud have separate sources of origin. The scapula and muscles that attach to the medial border of the scapula are derived from para-axially located somites whereas the majority of the limb bud structures of the upper limb are derived from lateral plate mesoderm which develops opposite somites
Study Bones of the Pectoral Girdle and Upper Extremity Flashcards at ProProfs - the appendicular skeleton bones of the pectoral girdle and upper extremity from an anatomy text book. The most proximal part of the upper extremity is the shoulder, or pectoral girdle. Its joints allow for a great amount of movement for the arm that’s attached to it. You’ll want to know the anatomy of the pectoral girdle in case a patient has sustained a shoulder injury or suffers from a medical disorder like arthritis (a degenerative.
Appendicular muscles of the pectoral girdle and arm. The pectoralis muscle of amphibians and reptiles is an intrinsic, fan-shaped muscle of the forelimb that usually runs from the sternum, clavicle and/or adjacent structures to the humerus and/or the scapula (e.g. Romer, ; Russell & Bauer, ; Diogo et al. a).

The functional morphology of the pectoral girdle and arm of Artibeus jamaicensis (Chiroptera: Phyllostomidae) was interpreted on the basis of gross dissection, high speed cinematography, and electromyography (EMG). EMG data obtained during flight for 17 muscles elucidate several temporal patterns of activity associated with the wingbeat cycle that contrast with the patterns of flexor, extensor Cited by: The pectoral girdle is made up of two major bones: the clavicle and scapula.
Clavicle bone. The clavicle or collarbone is an S-shaped bone situated at the front of Author: Kiara Anthony. The scapula is also part of the pectoral girdle and thus plays an important role in anchoring the upper limb to the body.
The scapula is located on the posterior side of the shoulder. It is surrounded by muscles on both its anterior (deep) and posterior (superficial) sides, and thus does not articulate with the ribs of the thoracic cage.
Muscles That Move the Humerus. Similar to the muscles that position the pectoral girdle, muscles that cross the shoulder joint and move the humerus bone of the arm include both axial and scapular muscles (Figure 2 and Figure 3).The two axial muscles are the pectoralis major and the latissimus dorsi.
The generalized teleost muscle morphology consists of pairs of muscles on either side of the pectoral girdle (Fig. Large arrectors, dorsal and ventral, attach to the marginal fin ray.
Adductors, superficial and deep, attach to the rest of the fin rays in a sheet. Gross dissectional and electromyographical (EMG) analysis were used to study the functional morphology of the pectoral girdle and upper limb musculature in Antrozous pallidus.
DIOGO, R. On the cephalic and pectoral girdle muscles of the deep-sea fish Alepocephalus rostratus, with comments on the functional morphology and phylogenetic relationships of the. Pectoral or shoulder girdle consists of both shoulder blades (scapulas) and collar bones (clavicles).
There are 5 joints and about 20 muscles involved in the pectoral girdle on each side. Function. The pectoral girdle connects the upper limbs to the axial skeleton and serves as the attachment site for the muscles of the upper back, chest and neck.
Other articles where Pectoral girdle is discussed: muscle: Tetrapod musculature: In tetrapods, unlike fishes, the pectoral girdle does not have a solid bony connection to the axial skeleton but rather is supported by a series of muscles derived from the outer layer of hypaxial trunk muscles.
This is no doubt another adaptation to life in an air environment, where the. Some comments on the functional morphology of these fishes, as well as a comparison with other otocephalans, are also given.
The paper is based on a review of the available literature and on the author’s own analysis of the cephalic and pectoral girdle musculature of members of the various major otocephalan groups, including representatives. The pectoral girdle, or shoulder girdle, consists of the lateral ends of the clavicle and scapula, along with the proximal end of the humerus, and the muscles covering these three bones to stabilize the shoulder joint.
The girdle creates a base from which the head of the humerus, in its ball-and-socket joint with the glenoid fossa of the. The shoulder girdle is also called the pectoral girdle, and it is a bone ring, incomplete shoulder girdle is formed by two sets of bones: the scapulae, posteriorly, the clavicles anteriorly and completed anteriorly by the manubrium of the sternum (part of the axial skeleton).
Those bones are part of the appendicular skeleton - consisting bones of the limbs (upper and lower. Figure – Pectoral Girdle: The pectoral girdle consists of the clavicle and the scapula, which serve to attach the upper limb to the sternum of the axial skeleton.
The scapula (shoulder blade) lies on the posterior aspect of the shoulder. It articulates with the humerus (arm bone) to form the shoulder joint (the glenohumeral joint). Muscles That Move the Humerus. Similar to the muscles that position the pectoral girdle, muscles that cross the shoulder joint and move the humerus bone of the arm include both axial and scapular muscles (Figure and Figure ).The two axial muscles are the pectoralis major and the latissimus dorsi.

the primary type of tissue responsible for stablizing position and bracing the pectoral girdle is. muscles. the large posterior process on the scapula that articulates with the distal end of the clavicle is the. acromion process.
The Shoulder girdle muscles move the clavicle (collar bone) and the scapula (shoulder blade). These generally move together as a unit. The muscles of the shoulder girdle are serratus anterior, pectoralis minor, levator scapulae, rhomboids, and trapezius.
Muscles Acting on the Shoulder Girdle, Muscles That Move the Upper Arm, Muscles That Move the Forearm, Muscles That Move the Wrist, Hand, and Fingers, tionship to function. For instance, a muscle with the bipen-nate ﬁber arrangement can produce a stronger contraction than a muscle having a parallel ﬁber arrangement.
functional morphology of the pectoral girdle and upper limb musculature in Antrozous pallidus. EMG data for 17 of the muscles suggest they are characterized as adductors, abductors, or bifunctional muscles; a classification which parallels the flexor, extensor, and bifunctional cate-gories described for terrestrial mammals.
Many authors have in fact noted that there are numerous evolutionary and functional reasons for the deep spatial relation between the skull and pectoral girdle in early gnathostomes: the girdle forms the rear wall of the internal branchial chamber, a shield for the pericardial cavity and a secure insertion for the pectoral fins.
7, 8, 68 In. Similar to the muscles that position the pectoral girdle, muscles that cross the shoulder joint and move the humerus bone of the arm include both axial and scapular muscles (Figure and Figure ). The two axial muscles are the pectoralis major and the latissimus dorsi.The girdle creates a base from which the head of the humerus, in its ball-and-socket joint with the glenoid fossa of the scapula, can move the arm in multiple directions.
Muscles That Position the Pectoral Girdle. Muscles that position the pectoral girdle are located either on the anterior thorax or on the posterior thorax (and).Muscles Crossing the Elbow Joint: Anterior: Posterior: mnemonics: Biceps Brachii: Triceps Brachii: Three B's Bend the elBow: Brachialis Biceps Brachioradialis.
