What skeleton is composed of 126 bones of the appendages and pectoral and pelvic girdles?
The appendicular skeleton is composed of 126 bones, including those of the upper and lower limbs as well as the pectoral and pelvic girdles. These bones are important for movement and provide connections to the axial skeleton.
Is the pectoral or pelvic girlde lightweight?
The pectoral girdle is typically lighter in weight compared to the pelvic girdle. This is because the pectoral girdle is designed for more flexibility and mobility in upper body movements, while the pelvic girdle provides support and stability to the lower body.
Does a pectoral girdle have a shallow or deep socket?
the pectoral has a shallow socket while the pelvic has a deep, secure socket. both for limb attachment.
Important to relate the structures of the axial and appendicular skeleton to one another?
The Skeleton can be divided into Axial and Appendicular portions. The Axial Skeleton, is the head and trunk, and include the bones of the skull, hyoid bone, vertebral column, and thoracic cage. The Appendicular Skeleton, contains the pelvic and pectoral girdles, as well as the upper and lower limbs. The limbs and girdles, of the Appendicular Skeleton, attach to the Axial Skeleton.
What are the structural components of the pectoral and pelvic limbs?
The structural components of the pectoral limbs (forelimbs) include the scapula, humerus, radius, ulna, carpals, metacarpals, and phalanges. In contrast, the pelvic limbs (hindlimbs) consist of the pelvis, femur, tibia, fibula, tarsals, metatarsals, and phalanges. Both limb types feature a combination of bones that provide support, mobility, and dexterity, with the pectoral limbs adapted for grasping and manipulation, while the pelvic limbs are designed for locomotion and weight-bearing. Additionally, both limbs include muscles, tendons, ligaments, and joints that facilitate movement and stability.

What are the 2 girdles of human body?
The pelvic girdle and the thoracic girdle. You are familiar how a body girdle goes around the body. These are the same. They make a girdle around the chest and around the pelvis.
What bones are included in each of pectoral and pelvic girdles?
The pectoral girdle is formed by the scapula, the humerus and the clavicle 3 bones in total
How is the weight of an amphibian's body transferred to the limbs?
The weight of an amphibian's body is transferred to the limbs by using the pectoral and pelvic girdles.
The anterior portion of the PELVIC girdles is known as the?
ilium
Hypothesize why the pelvic bones of a four-legged animal such as a cat or pig are much less massive than those of a human?
In a four-legged animal, the weight of the body would be distributed between the pelvic and pectoral girdles. In humans, the pelvis has to support the weight of the whole trunk.
Are girdles in the axial skeleton?
no, they are found in the appendicular skeleton
Is the pectoral or pelvic girlde lightweight?
The pectoral girdle is typically lighter in weight compared to the pelvic girdle. This is because the pectoral girdle is designed for more flexibility and mobility in upper body movements, while the pelvic girdle provides support and stability to the lower body.
Compare the pectoral and pelvic girdles in terms of flexibility allowed?
Flexibility: pectoral girdle is more flexible-less ligaments, ball and socket joint is shallower Security: pelvic girdle is more secure, deeper socket. there are more dislocated shoulders than dislocated hips ability to bear weight: pelvic girdle can bear more weight-the pelvic girdle has bones that are fused (os coxa) and a joint with the sacrum. the pectoral girdle has a little bone called the clavicle connecting it to the body wall.
What are Descriptive terms for the pectoral girdles?
I just had this on my homework.The answers for Pectoral are A. Flexibility, C. Lightweight, D. Shallow socket for limb attachment.For Pelvic, B. Massive, E. Deep, secure socket for limb attachment, F. Weight-bearing.Hope that helps!

Which component of the skeletal system is made up of the upper and lower limbs and the pelvic and shoulder girdles?
The appendicular skeleton is the component of the skeletal system that consists of the upper and lower limbs, as well as the pelvic and shoulder girdles. This part of the skeleton is involved in movement and provides stability and support to the body.
