What can the spinal cord teach us about learning and memory?
The spinal cord has a key role because it is the final common pathway for all behavior and is a site of substantial plasticity. … Experimental models based on spinal cord reflexes facilitate study of the gradual plasticity that makes possible most rapid learning phenomena.
What protects the spinal cord?
The spinal cord is protected by bones, discs, ligaments, and muscles. The spine is made of 33 bones called vertebrae. The spinal cord passes through a hole in the center (called the spinal canal) of each vertebra. Between the vertebrae there are discs that act as cushions, or shock absorbers for the spine.
How does your spinal cord work?
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.
What parts of the body does the spine control?
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.
