What is a longitudinal axis for a bone?
The longitudinal axis of a bone is an imaginary line that runs along the length of the bone from one end to the other. It helps to define the orientation and direction of forces acting on the bone, such as during movement or weight-bearing activities. Understanding the longitudinal axis is important in biomechanics and in the study of bone structure and function.
Which moves a bone around its longitudinal axis?
rotation!
Which bone has long longitudinal axis and expanded ends?
The humerus is a bone in the upper arm that has a long longitudinal axis with expanded ends where it articulates with the scapula at the shoulder joint and the radius and ulna at the elbow joint.
What movement turns a bone along an axis?
Rotation is the movement around a longitudinal axis.
A fracture or break in a bone that runs parallel with the bone is known as a?
longitudinal fracture
What is a greenstick fracture?
A greenstick fracture is afracture in a young, soft bone in which the bone bends and partially breaks. The bones become harder(calcified) and more brittle with age, it occurs almost exclusively during infancy and childhood when their bones are soft. The name is by analogy with green wood which similarly breaks on the outside when bent. There are three basic forms of greenstick fracture. In the first a transverse fracture occurs in the cortex, extends into the midportion of the bone and becomes oriented along the longitudinal axis of the bone without disrupting the opposite cortex. The second form is a torus or buckling fracture, caused by impaction. The third is a bow fracture in which the bone becomes curved along its longitudinal axis.

What canal is the horizontal passageway that joins with a vertical passage that runs with the longitudinal axis of the bone?
The canal you are referring to is known as a Haversian canal, which is part of the osteon structure in compact bone. The Haversian canal runs longitudinally along the axis of the bone and is surrounded by concentric lamellae of bone tissue. It is connected to the Volkmann's canals, which are the horizontal passageways that link adjacent Haversian canals and provide pathways for blood vessels and nerves. Together, they facilitate the transport of nutrients and waste products within the bone.
What type of bone is the axis?
irregular bone
How many longitudinal sections can be made through the thigh bone?
2
What fracture cracks a bone in half?
This is either a greenstick fracture or a longitudinal fracture depending upon exactly how the bone breaks.
Does the axis form a joint with the hip bone?
No, the axis is located in the neck.
