Tetrapod-like pelvic girdle in a walking cavefish : Scientific Reports

Pelvic girdle morphology

We found that Cryptotora had a pelvic girdle that is connected to the axial skeleton via fusion with a hypertrophied rib of the seventh vertebra (Fig. 2A–C, Supplementary Video 2). The basipterygium, or puboischiadic plate (pu, tan, Fig. 2C), was broad in both anteroposterior and lateral directions and more heavily ossified than is typical of fishes (Fig. 3), with a large concavity for ventral attachment of muscles to the large processes at the base of the fin rays (pf, blue, Fig. 2B,C). The heads of the fin rays articulated with the lateral edges of the ischium.

What is the function of the pectoral girdle? | Reference.com

Full Answer

The long, upper bone in the arm, called the humerus, fits into the scapula via a depression called the glenoid cavity. Unlike the pelvic girdle, the pectoral girdle relies on muscular connections to hold it into place, rather than a physical joint structure. The rhomboids, trapezius and levator scapulae muscles attach the upper part of the pectoral girdle to the axis of the body. The serratus anterior, located underneath the armpit, holds the girdle into place by attaching to the ribcage.

The pelvic viscera, (bladder, rectum, pelvic genital organs and terminal part of the urethra) reside within the pelvic cavity (or the true pelvis). This cavity is located within the lesser part of the pelvis, beneath the pelvic brim.

The Pectoral Girdle

By the end of this section, you will be able to: * Describe the bones that form the pectoral girdle * List the functions of the pectoral girdle

The appendicular skeleton includes all of the limb bones, plus the bones that unite each limb with the axial skeleton ([link]). The bones that attach each upper limb to the axial skeleton form the pectoral girdle (shoulder girdle). This consists of two bones, the scapula and clavicle ([link]). The clavicle (collarbone) is an S-shaped bone located on the anterior side of the shoulder. It is attached on its medial end to the sternum of the thoracic cage, which is part of the axial skeleton. The lateral end of the clavicle articulates (joins) with the scapula just above the shoulder joint. You can easily palpate, or feel with your fingers, the entire length of your clavicle.
