Solution

The region of the sternum that articulates with the greatest number of ribs is the?

Ans . Body.

The sternum has 3 parts: the manubrium, body and xiphoid process. Body is the part where greatest number of ribs articulation takes place.

All of the above has the same number of ribs articulations?

Body , manubrium, xiphoid process

Ans. In body, the articular facets articulate with the costal cartilages of ribs 3-6 and smaller facets with parts of 2nd and 7th ribs called as demifacets

Manubrium, the facet articulate with the costal cartilage of 1st rib and demifacet articulate with the costal cartilage of 2nd rib

Xiphoid process, it articulate with part of the costal cartilage of 7th rib.

A bone that contains a diaphysis and epiphysis, a tuberosity near its proximal end, and proportionally more compact than spongy bone is the?

Ans. Radius

Radius and ulna are the two bones of the lower arm. Humerus connects scapula with these two bones.

The first seven ribs articulate anteriorly with the sternum and posteriorly with the

Ans. Thoracic vertebrae.

Each rib is a curved, flattened bone that contributes to the wall of the thorax. Ribs articulate posteriorly with the T1- T12 thoracic vertebrae.
