Where is information integrated in the spinal cord?

For example, specialized nerve endings often act as sensors (receptors), information is carried along nerves and/or tracts of the spinal cord, integration occurs within the CNS, and spinal cord tracts and nerves carry the responding information back out to the effectors.

Does the spinal cord integrate information?

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. It also controls simple musculoskeletal reflexes without input from the brain.

What is integration in the spinal cord?

at the spinal cord level, afferent impulses produce simple reflex responses. at higher CNS levels, increasing complexity mediates increasingly complicated motor responses. in the intact system, lower motor responses are submerged in the total pattern of motor activity.

Where does the spinal cord relay information to?

Nervous system – Spinal Cord

Like your brain, your spinal cord is part of your central nervous system. Its main function is to relay information about what’s happening inside and outside your body to and from your brain. 31 pairs of spinal nerves connect your spinal cord to the rest of your body.

Which part of the spinal cord contains sensory information?

The white matter of the spinal cord is subdivided into dorsal (or posterior), lateral, and ventral (or anterior) columns, each of which contains axon tracts related to specific functions. The dorsal columns carry ascending sensory information from somatic mechanoreceptors (Figure 1.11B).

Are reflexes integrated in spinal cord?

Nervous system

Spinal reflexes are reflexes for which the integration center is located in the gray matter of the spinal cord.

What are the two tracts of the spinal cord?

The ascending tracts carry sensory information from the body, like pain, for example, up the spinal cord to the brain. Descending tracts carry motor information, like instructions to move the arm, from the brain down the spinal cord to the body.

Which spinal nerves affect which parts of the body?

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.

What information is processed in the spinal cord?

The spinal cord itself is a long bundle of nerve cells encased in the 33 vertebral bones known individually as vertebra. The spinal cord is the body’s central processing center, receiving information from the brain and sending it to branching nerves that connect with every other area of the body.

What are the three areas of the spine?

The spine has three normal curves: cervical, thoracic and lumbar. There are seven cervical vertebrae in the neck, 12 thoracic vertebrae in the torso and five lumbar vertebrae in the lower back.

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).
