What are the 3 main parts of a vertebra?

Cervical, Thoracic and Lumbar Spine Each vertebra is made up of the vertebral body in the front, the facet joints in the back and the pedicles, which connect the vertebral body to the facet joints.

What bones make up the vertebrae?

Vertebrae are the 33 individual bones that interlock with each other to form the spinal column. The vertebrae are numbered and divided into regions: cervical, thoracic, lumbar, sacrum, and coccyx (Fig. 2). Only the top 24 bones are moveable; the vertebrae of the sacrum and coccyx are fused.

What are the two bones that stick out of your back?

Pedicles. Each vertebra has two cylinder-shaped projections (pedicles) of hard bone that stick out from the back part of the vertebral body, providing side protection for the spinal cord and nerves. The pedicles also serve as a bridge, joining the front and back parts of the vertebra.

What are the 5 sections of the vertebrae?

The spine is composed of 33 bones, called vertebrae, divided into five sections: the cervical, thoracic, and lumbar spine sections, and the sacrum and coccyx bones. The cervical section of the spine is made up of the top seven vertebrae in the spine, C1 to C7, and is connected to the base of the skull.

What are the names of back problems?

How many spinal cords are in the human body?

In humans there are 31 pairs: 8 cervical, 12 thoracic, 5 lumbar, 5 sacral, and 1 coccygeal. Each pair connects the spinal cord with a specific region of the body. Near the spinal cord each spinal nerve branches into two roots.

What part of the spine controls the legs?

The lumbosacral spinal cord and nerve supply legs, pelvis, and bowel and bladder. Sensations from the feet, legs, pelvis, and lower abdomen are transmitted through the lumbosacral nerves and spinal cord to higher segments and eventually the brain.

What vertebrae controls bowels?

The lowest part of the spinal cord is the sacral spinal cord. Bladder function, bladder and bowel external sphincters, sexual functions (including erections and ejaculation in men and responsiveness in women), and some leg muscles are the domain of the sacral spinal cord.

What happens if spinal cord is damaged?

When the spinal cord is damaged, the message from the brain cannot get through. The spinal nerves below the level of injury get signals, but they are not able to go up the spinal tracts to the brain. Reflex movements can happen, but these are not movements that can be controlled.

What nerves control the legs?

Sciatic Nerve Anatomy

• The sciatic nerve is formed in the lower spine by the combination of motor and sensory fibers from spinal nerves L4 to S3.
• This long, thick, and bulky nerve runs along the back of the thigh and leg and terminates in the foot.
• The nerve supplies most areas of the thigh, leg, and foot.
