The average length of tibia is 40.50 CM.
	Humerus bone connects shoulder with elbow in human arm. It is a long bone which consists of three parts i.e. upper extremity of Humerus, body of Humerus and lower extremity of Humerus. Humerus forms the upper part of human arm and many important muscles are attached with it. The average length of tibia is 36.46 CM.
	Ulna forms the inner-lower part of human arm. This fore-arm bone along with radius completes the lower part of human arm. Its average length in 28.20 Cm. In simple words it connects elbow with hand. It is a long and narrow bone with many muscles attached with it.
	Radius is a long bone which forms the outer-lower part of human arm. It is on the lateral side of Ulna and its length is 26.42 cm. Radius is also found in some four-leg animals as lower part of forelimb. Like Ulna it connects hand with elbow.
	7th rib is part of the 24 ribs found in a human body. The average length of 7th rib is 24.00 CM. Ribs are basically found in Vertebrates and they support the upper body of vertebrates.
	8th rib: These long and curved bones are considered as the basic structural part of human body. 8th rib is the part of 12 pairs of ribs in human body. The average length of 8th rib is 23.00 CM.
	Innominate bone is also called hipbone or half pelvis. It is the 9th largest bone in human body. Its average length is 18.50 Cm. Innominate bone is either of the two bones that form the sides of the pelvis, consisting of three fused components, the ilium, ischium, and pubis Nontechnical name hipbone.
