Best answer: What part of the spine does the spinal cord travel?

In humans, the spinal cord begins at the occipital bone, passing through the foramen magnum and entering the spinal canal at the beginning of the cervical vertebrae. The spinal cord extends down to between the first and second lumbar vertebrae, where it ends.

What part of the vertebrae does the spinal cord pass through?

The spinal cord passes through the foramen of each vertebra. The anterior arch is called the vertebral body.

Where does the spinal cord start and end?

About the spinal cord and nerve roots

The spinal cord originates in the brain, exiting through a hole at the skull base called the foramen magnum and coursing through the spinal canal of the cervical, thoracic and upper lumbar spine before ending most commonly between the first and second lumbar vertebrae.

How far does the spinal cord go down the vertebrae?

The spinal cord extends from the foramen magnum where it is continuous with the medulla to the level of the first or second lumbar vertebrae. It is a vital link between the brain and the body, and from the body to the brain. The spinal cord is 40 to 50 cm long and 1 cm to 1.5 cm in diameter.

What part of the spine controls the heart?

Thoracic (mid back) – the main function of the thoracic spine is to hold the rib cage and protect the heart and lungs. The twelve thoracic vertebrae are numbered T1 to T12.

What part of spine is most prone to injury?

Understandably, the lumbar spine is the most commonly injured region of the spinal column. The lowest portion of the spine, the part that is connected to the pelvis, is called the sacrum.

What part of your spine controls your legs?

The nerves of the cervical spine go to the upper chest and arms. The nerves in your thoracic spine go to your chest and abdomen. The nerves of the lumbar spine then reach to your legs, bowel, and bladder. These nerves coordinate and control all the body’s organs and parts, and let you control your muscles.

Is spinal cord injury a disability?

Anyone with a spinal cord injury can file a claim for Social Security disability benefits as long as the injury has lasted at least three months and is expected to make it impossible for you to work for at least 12 months.

How does damage to the spinal cord and nerves affect the other parts of the body?

Complete: A complete injury causes total paralysis (loss of function) below the level of the injury. It affects both sides of the body. A complete injury may cause paralysis of all four limbs (quadriplegia) or the lower half of the body (paraplegia).

What part of the body does the lumbar spine control?

These lumbar vertebrae (or lumbar bones) contain spinal cord tissue and nerves which control communication between the brain and the legs. Damage to the lumbar spinal cord subsequently affects the hips and groin area, and may impact the lower abdominal muscles and thigh flexion as well.

Why does the spinal cord hurt?

Conditions commonly linked to back pain include: Muscle or ligament strain. Repeated heavy lifting or a sudden awkward movement can strain back muscles and spinal ligaments. If you’re in poor physical condition, constant strain on your back can cause painful muscle spasms.

What is the difference between the spine and the spinal cord?

The spine is made up of a column of bones called vertebrae (spinal column). The spinal cord, a long, fragile structure contained in the spinal canal which runs through the centre of the spine, is protected by the vertebrae.

What is the difference between white and GREY matter in the spinal cord?

Grey matter is distinguished from white matter in that it contains numerous cell bodies and relatively few myelinated axons, while white matter contains relatively few cell bodies and is composed chiefly of long-range myelinated axons. The colour difference arises mainly from the whiteness of myelin.
