Are Vertebrochondral ribs Bicephalic?
Are Vertebrochondral ribs Bicephalic?
Each rib is a thin cut of beef connected dorsally to the vertebral column and ventrally to the sternum. It has two articulation surfaces on its dorsal end and is therefore known as bicephalic. Vertebrochondral ribs termed to the $8^{th}$ -$10^{th}$ pairs of ribs.
How many vertebral ribs are there?
The rib cage surrounds the lungs and the heart, serving as an important means of bony protection for these vital organs.In total, the rib cage consists of the 12 thoracic vertebrae and the 24 ribs, in addition to the sternum.
Which ribs are Vertebrochondral?
There are three pairs of false ribs. They are intermediate between the true ribs and the floating ribs. They are sometimes called vertebrochondral ribs.
How many Vertebrochondral ribs are?
There are three pairs of vertebrochondral ribs (eighth to tenth) that connect indirectly to the sternum via the costal cartilages of the ribs above them.
What are Vertebrochondral ribs Class 11?
Vertebrochondral ribs refers to the eighth-to-twelfth pairs of ribs. The eighth-to-tenth pairs of ribs connect to the sternum indirectly via the costal cartilages of the ribs above them.

Where is rib 8 and 9?
The false ribs (8,9,10) are the ribs that indirectly articulate with the sternum, as their costal cartilages connect with the seventh costal cartilag by the costochondral joint. The floating ribs (11,12) do not articulate with the sternum at all (distal two ribs).
Where is the 11th rib?
The eleventh rib is categorised as one of the ‘floating’ ribs. It articulates posteriorly with the eleventh thoracic vertebra. Anteriorly, its free end is ensheathed within muscle and does not articulate with the sternum.
What are the differences between a Vertebrosternal Vertebrochondral and vertebral rib?
True (vertebrosternal) ribs are ribs 1–7. The costal cartilage for each of these attaches directly to the sternum. False (vertebrochondral) ribs, 8–12, are attached either indirectly or not at all to the sternum. Ribs 8–10 are attached indirectly to the sternum.
How many different ribs are there?
As such, ribs can be allocated to one of three distinct types; true (vertebrosternal) ribs, false (vertebrochondral) ribs and floating (vertebral, free) ribs. Ribs one to seven are considered true ribs and attach directly to the sternum via their own costal cartilage.
Which ribs are floating ribs?
The 8th, 9th, and 10th pairs—false ribs—do not join the sternum directly but are connected to the 7th rib by cartilage. The 11th and 12th pairs—floating ribs—are half the size of the others and do not reach to the front of the body.
What is floating ribs Class 5?
Floating rib: One of the last two ribs. A rib is said to be “floating” if it does not attach to the sternum (the breast bone) or to another rib. False ribs: The lower five ribs do not directly connect to the sternum and are known as false ribs.
How many pairs of vertebrochondral ribs are in the human body?
There are three pairs of vertebrochondral ribs (eighth to tenth) that connect indirectly to the sternum via the costal cartilages of the ribs above them. [1] [2] Their elasticity allows rib cage movement for respiratory activity.
What does vertebrochondral mean?
Vertebrochondral ribs refers to the eighth-to-twelfth pairs of ribs. The eighth-to-tenth pairs of ribs connect to the sternum indirectly via the costal cartilages of the ribs above them. Was this answer helpful?
Which ribs are vertebrosternal ribs?
Which ribs are Vertebrosternal ribs? vertebrosternal ribs. The vertebrosternal ribs are those connecting thoracic vertebrae to the manubrium and sternum. They include ribs 2 to 6 or 7. The second rib can display atypical features, but otherwise this group is typical.
How are the ribs of the thoracic vertebrae numbered?
All ribs are attached posteriorly to the thoracic vertebrae and are numbered accordingly one to twelve. Ribs that articulate directly with the sternum are called true ribs, whereas those that do not articulate directly are termed false ribs. The false ribs include the floating ribs (eleven and twelve) that are not attached to the sternum at all.
