The spine can bend. But if you mean each individual vertebrae they cannot bend. They are made of hard bone. The elasticity of the spine is made possible by the inter-vertebral pads located between each vertebral unit. If the pads wear out the vertebral bones will rub against small nerves, blood vessels, spinal cord and possibly the marrow. So to clarify the vertebral column known as the spine can bend. Each vertebra made of hard bone does not bend and can be fractured if forced hard enough by a hard blow. I have added my favorite explanation with great diagrams for you. You can look in our reference library too but I like the pictures on this web article the best. Click on the related link below.
They "bend backwards" only if you look at them as a whole. They each do not but together they can make slight backward movements.

Almost all the joints between vertebrae are movable. The joints between the cervical vertebrae and lumber vertebrae have fairly good movement. Between thoracic vertebrae only you have less movement. But then they do move on each other.
A cow's vertebrae form the backbone or spine, providing structural support and protecting the spinal cord. They allow for flexibility and movement, enabling the cow to bend and twist its body while walking, grazing, or standing. Additionally, the vertebrae play a crucial role in maintaining the overall posture and balance of the animal.
Snakes have a high number of vertebrae, up to 500 or more, because they have evolved to have a highly flexible and elongated body shape that allows them to move efficiently and adapt to various environments. This increased number of vertebrae gives them the ability to bend and twist in a variety of ways, aiding in their hunting and survival strategies.
When you bend your back, it is often referred to as "flexion" of the spine. This movement typically involves decreasing the angle between the vertebrae, such as when you lean forward. Flexion is a normal range of motion for the spine, but it should be done with care to avoid strain or injury.
Vertebrae are divided into sections: the atlas and axis account for the first cervical vertebrae, of which there are 7 in total; there are 12 thoracic vertebrae, 7 lumbar vertebrae, 1 sacrum (5 separate vertebrae in a baby), and 1 coccyx (4 separate vertebrae in a baby).
Acoelous vertebrae are a type of vertebrae that have flat, concave surfaces on both the top and bottom of the vertebral body. This structure allows for limited movement between adjacent vertebrae, primarily in flexion and extension. Acoelous vertebrae are found in certain species of reptiles and some primitive mammals, and their flat shape helps provide stability and support for the spinal column.
the thoracic spine is above the lumbar spine which means ALL thoracic vertebrae are superior to the lumbar vertebrae.
Vertebrates have vertebrae .
Your spinal column, made up of 24 vertebrae plus the sacrum and the coccyx dorms a long, bony tube which protects the delicate nerves of your spinal cord.
