The spinal cord is a long, thick structure of tubes that extend from the end of the brain stem to around the bottom of the spinal cord. the body It is also the center of reflexes such as knee reflexes.
Like the brain (meninges), the spinal cord is protected by three layers of tissue. The intermediate movements of the spinal cord are the spinal cord and meninges. In most adults (vertebrates), the spinal cord consists of 33 individual vertebrae. Just as the skull covers the brain, the spinal cord is covered with spines.
What is Spinal Cord?
The white matter in the background has ascending and descending tracts.
Ascending pathways are responsible for the transmission of sensory information from receptors to the central nervous system. It originates in the spinal canal.
The dorsal-ventral spinal cord pathways are responsible for the transmission of unconscious dispositional sensory information from muscles and tendons to the lower half of the spinal cord. brain There are four main parts in the abdominal cavity, viz.
What is Backbone?
The spine is another name for which the spinal area is used to identify. The vertebral column is the rotational column from the neck to the tail of the vertebral body.
The main characteristic used to distinguish vertebrates from other stars is usually the presence of a spine. Most spines are formed by stars and this notochord can be detected during embryonic development in vertebrates. Later, it develops into a spine.
The human spinal cord consists of 33 vertebrae. Inside the canal, the spine extends from head to tail. It also provides protection to the spine and provides nerve release from the spinal cord.
The spinal cord is basically one of two central nervous systems, with the brain being the second. Here, the spine supplies muscles such as the pelvis and pelvic girdle, as well as many of the muscles of the joint positions. In addition, if it remains.
Difference Between Spinal Cord and Backbone
| Spinal Cord | Backbone |
| Composition | |
| Made up of bundles of nerve fibres | The backbone is made of bones called vertebrae |
| Function | |
| The spinal cord acts as a pathway for communication between the brain and the body | The backbone serves to provide structural support as well as support the body’s weight. It is also tasked with protecting the spinal cord |
| Segments | |
| The spinal cord forms 31 segments, which are divided into 8 cervical nerves, 5 lumbar nerves, 12 thoracic nerves, 1 coccygeal nerve and 5 sacral nerves | The backbone can be split into 5 major segments – the cervical spine, the thoracic spine and the lumbar spine, the sacrum and the coccyx. The cervical spine is made up of 7 bones called vertebrae. The thoracic spine has 12 vertebrae, and the lumbar spine and 5 vertebrae. |
