The spinal nerves carry electrical signals from the brain to muscles of the skeleton and internal organs via the spinal cord. Similarly, they carry sensory information like touch, pressure, cold, warmth, pain and other sensations from the skin, muscles, joints and internal organs to the brain via the spinal cord.
How does the spinal cord work with other systems to keep the body healthy?
The vertebrae protect the spinal cord from injury. Sensory receptors in joints between bones send signals about body position to the brain. The brain regulates the position of bones by controlling muscles.
How does the spinal cord work with the nervous system?
Without a central nervous system you would be unable to think or feel, to voluntarily move, or even to breathe. The spinal cord acts as the body’s telephone system, relaying information from the brain to the rest of the body, and sending signals about the rest of the body to the brain.
What two systems does the spinal cord integrate?
The central nervous system CNS is responsible for integrating sensory information and responding accordingly. It consists of two main components: The spinal cord serves as a conduit for signals between the brain and the rest of the body.
What part of the body does the spinal cord control?
The spinal cord is a long bundle of nerves and cells that extends from the lower portion of the brain to the lower back. It carries signals between the brain and the rest of the body.
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.
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).
Which part of the spine is most vulnerable to injury?
The most vulnerable areas of the spine are the lumbar (lower back), and the cervical (neck) regions. They are the most mobile, and susceptible to injury. The lower back is also the main weight bearing part of the spine. The spine is supported by muscles and ligaments.
What connects the brain to the spinal cord?
The brain stem is a bundle of nerve tissue at the base of the brain. It connects the cerebrum and cerebellum to the spinal cord.
