What are the 5 parts of appendicular skeleton?

The appendicular skeleton includes the bones of the shoulder girdle, the upper limbs, the pelvic girdle, and the lower limbs.

What part of the skeleton is the sternum?

The sternum (or breastbone) is a flat bone located at the anterior aspect of the thorax. It lies in the midline of the chest and has a ‘T’ shape. As part of the bony thoracic wall, the sternum helps protect the internal thoracic viscera – such as the heart, lungs and oesophagus.

Is the scapula part of the axial or appendicular skeleton?

The pelvis, femur, fibula, tibia and all of the foot bones as well as the scapula, clavicle, humerus, radius, ulna and all of the hand bones are classified as appendicular.

What bones are not a part of the appendicular skeleton?

The hyoid is a bone located in the throat, and it is the only bone in our body that is not connected to another bone. The main function of the human skeleton is to protect our internal organs and provide support and attachment surfaces for our muscles to make the body mobile.

Is the sacrum part of the appendicular skeleton?

The sacrum is not part of the appendicular skeleton. The sacrum is one of the lower bones in our vertebral column.

Why is a bone like the scapula considered part of the appendicular skeleton and not the axial skeleton?

(Q004) Why is a bone like the scapula (shoulder blade) considered part of the appendicular skeleton and not the axial skeleton? The scapula is part of the appendicular skeleton is because it has the appendix bones while the axial bone is connected to the humerus and the clavicle is the shoulder cap bone.

Which structure of the sternum articulates with the appendicular skeleton?

The medial end, known as the sternal end of the clavicle, has a triangular shape and articulates with the manubrium portion of the sternum. This forms the sternoclavicular joint, which is the only bony articulation between the pectoral girdle of the upper limb and the axial skeleton.

What are the 3 parts of the sternum?

The sternum is a partially T-shaped vertical bone that forms the anterior portion of the chest wall centrally. The sternum is divided anatomically into three segments: manubrium, body, and xiphoid process.

Article first time published on

Is the manubrium part of the sternum?

The manubrium. The manubrium is the thickest and strongest portion of the sternum and is therefore the area that is most likely to survive inhumation. It is broad and thick along its superior margin and narrows towards its inferior articulation with the mesosternum (Jit et al., 1980).

What is the sternum made of?

The sternum is composed of highly vascular tissue, covered by a thin layer of compact bone which is thickest in the manubrium between the articular facets for the clavicles. The inferior sternopericardial ligament attaches the pericardium to the posterior xiphoid process.

What is the appendicular skeleton quizlet?

Appendicular Skeleton. Consists of the bones of the upper and lower limbs, together with the shoulder girdle and the pelvic girdle. The bones of the limbs are attached to the axial skeleton by the means of the shoulder girdle and the pelvic girdle.

Which bone is the scapula?

The scapula is a flat, triangular-shaped bone (colloquially as the “shoulder blade“). It is located in the upper thoracic region on the dorsal surface of the rib cage. It connects with the humerus at the glenohumeral joint as well as the clavicle at the acromioclavicular joint to form the shoulder joint.

Which bone is part of the appendicular skeleton quizlet?

The clavicle, shoulder girdle, humerus, pelvic girdle, and femur are part of the appendicular skeleton.

What are the three components of the sternum and what ribs articulate directly to the sternum?

In mammals the sternum is divided into three parts, from anterior to posterior: (1) the manubrium, which articulates with the clavicles and first ribs; (2) the mesosternum, often divided into a series of segments, the sternebrae, to which the remaining true ribs are attached; and (3) the posterior segment, called the …

What are the 4 parts of the thoracic cage?

The thoracic cage surrounds and protects the heart and lungs in the thoracic cavity. It consists of the ribs, the sternum, and the thoracic vertebrae, to which the ribs articulate. We examined the thoracic vertebrae last lab, so here we will only examine the ribs and sternum. There are twelve pairs of ribs.

Which of the following is not one of the three parts of the sternum?

The correct answer is (A). costal groove. The sternum has three parts, which are the manubrium, the body, and the xiphoid process. The costal groove is a feature on ribs and not the sternum.

What articulates with the sternum?

The sternum articulates with the clavicles and costal cartilages of the ribs. It also covers and protects the heart.

What structure connects the ribs to the sternum?

Anteriorly, each rib ends in a costal cartilage. True ribs (1–7) attach directly to the sternum via their costal cartilage.

What is the scientific name for sternum?

Shaikh. Feb 29, 2016. The sternum is also called the breast bone. It is a bone in the anterior of the chest.

What organs are under the sternum?

The medulla is the inside part of the thymus.
The cortex is the layer that surrounds the medulla.
The capsule is the thin covering over the outside of the thymus.

How does the sternum develop?

Embryologically, two cartilaginous sternal bars emerge in the space between the ribs. … The manubrium usually has one to three centers of ossification, whilst the two sternal bars fuse across the midline to form four units called sternebrae, each with one or two centers of ossification.

What are the main parts of the appendicular skeleton What are their functions?

The human appendicular skeleton is composed of the bones of the upper limbs (which function to grasp and manipulate objects) and the lower limbs (which permit locomotion). It also includes the pectoral (or shoulder) girdle and the pelvic girdle, which attach the upper and lower limbs to the body, respectively.
