Your pectoral girdles are responsible for providing structural support to your shoulder region on the left and right side of your body. They also allow for a large range of motion, connecting muscles necessary for shoulder and arm movement. The pectoral girdles on either side of your body aren’t joined together.

What is girdle in biology?
a bony structure to which the limbs of vertebrates are attached.
What is the difference between a girdle and a joint?
The glenohumeral joint, or shoulder joint, is the ball-and-socket connection between the humerus and scapula. When we think about how the arm and shoulder are connected, this is usually the joint we picture. Your shoulder girdle is the most agile and also the most vulnerable joint in the body.
What are the elbow joints?
The three joints of the elbow include:
- Ulnohumeral joint is where movement between the ulna and humerus occurs.
- Radio humeral joint is where movement between the radius and humerus occurs.
- Proximal radioulnar joint is where movement between the radius and ulna occurs.
How is the pectoral girdle attached?
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.
What are the 4 bones in the shoulder girdle?
INTRODUCTION. The shoulder girdle is made up of four articulations (sternoclavicular, acromioclavicular, glenohumeral, and scapulothoracic) and three bones (clavicle, scapula, and humerus). These articulations allow the shoulder girdle to provide a large range of motion for the hand to locate itself maximally in space.
What is the longest bone in the body?
The femur The femur is the strongest bone in the body, and it is the longest bone in the human body.
What is the role of girdles in skeleton?
The pelvic girdle attaches to the lower limbs of the axial skeleton and is responsible for bearing the weight of the body and for locomotion. It is securely attached to the axial skeleton by strong ligaments. It also has deep sockets with robust ligaments to securely attach the femur to the body.
What is the difference between pelvis and pelvic girdle?
The key difference between pelvis and pelvic girdle is that the pelvis is a lower part of the trunk that composes several bones such as a pair of bones, sacrum and coccyx while the pelvic girdle is one of the two parts of the bony pelvis that composes two appendicular hip bones oriented in a ring.
What is the difference between a male and female pelvic girdle?
The pelvis is one of the most useful skeletal elements for differentiating between males and females. Female pelves are larger and wider than male pelves and have a rounder pelvic inlet. Male iliac crests are higher than females, causing their false pelves to look taller and narrower.
What makes up the pelvic girdle?
In discussing the pelvis, a distinction can be made between the pelvic spine and the pelvic girdle. The pelvic girdle, also known as the os coxae, Latin for bone of the hip, consists of the fused bones identified individually as the ilium, ischium, and pubis.
What are girdles and scabbards?

Why is the pectoral girdle more free than the pelvic girdle? … It is is not firmly and inflexibly anchored to the upper thorax as the pelvic girdle is to the sacrum.

How is the scapula attached to the posterior wall of the thorax?
The ventral surface of the scapula abuts the thoracic rib cage and has a large concavity called the subscapular fossa where the subscapularis attaches. … The dorsal surface divides into two unequal parts via the scapular spine which runs across from the posterior scapula before forming the acromion.
Where does the pelvic girdle attach to the axial skeleton?
sacrum The pelvic girdle (hip girdle) is formed by a single bone, the hip bone or coxal bone (coxal = hip), which serves as the attachment point for each lower limb. Each hip bone, in turn, is firmly joined to the axial skeleton via its attachment to the sacrum of the vertebral column.
What bone forms Brachium?
The brachium (Bra-KEY-um) or arm, refers to the upper limb which consists of only the humerus (Hu-me-RUS). The brachium radiates from the glenohumeral joint to the elbow joint, connecting the proximal end of the scapula to the distal end of the radius and the ulna.
