No... your ear or pelvic bone are curved.
These intermediate bones are metacarpals. Distally, there are the phalanges, the straight bones of the fingers. These connect to the straight metacarpals. These connect to the carpals, or wrist bones, which connect to the arm bones.
No, only a few large long bones (such as the femur and the humerus) and some large irregular bones (such as the crest of the ilium of the pelvis) have red marrow. Most bones have no marrow.
The arm and leg bones keep your arms and legs straight
no a snake cannot move in a straight line as its bones are not stretchable_^^^^^^^^^^&
straight.
Bones will not cause the arm to be in a straight position, instead, muscle and tendons will cause the arm to be straight.
the bones are rigid --------- I think a better way to answer this is they are rigid, but both curved and straight. Have you ever seen a picture of the femur, the pelvis, or the scapula? What about the clavicle? These bones, as all bones are, are rigid. They hold their shape (unlike the cartilage of the ear or nose) but are curved. A rigid straight bone could be named as the phalanges, or the humerus (MAYBE). I mean, even the radius and ulna are curved a small amount.
