To solve the question "Spinal cord passes to brain through:", we need to analyze the provided options and determine which foramen serves as the passageway between the spinal cord and the brain.1. Understand the Options: The opt
Lumbar spinal stenosis is a condition defined as the narrowing of the bone canals (vertebral foramen or intervertebral foramen) where the spinal cord passes through the spine. When this narrowing occurs, the spinal cord or nerves respectively, can be compressed which may cause pain and/or nerve ...
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. What is the structure and function of the spinal cord? Spinal cord and nerves: The spinal cord is...
Fig. 2.8 is a schematic sketch of a vertebra: its bone forms a solid main body and behind it a ring-like opening (foramen) that protects the spinal cord which runs up and down. It also has openings (foramina) for sensory and motor nerve branches (roots) to the left and right. The ...
A spinal cord injury (SCI) is damage to the tight bundle of cells and nerves that sends and receives signals from the brain to and from the rest of the body. The spinal cord extends from the lower part of the brain down through the lower back. An SCI can occur anywhere along the spi...
What is a mixed spinal nerve? The term spinal nerve generally refers to the mixed spinal nerve, which is formed from the dorsal and ventral roots that come out of the spinal cord. The spinal nerve is the bit that passes out of the vertebrae through the intervertebral foramen. ...
The spinal cord is located in the vertebral cavity (OpenStax College, 2013) and connects the brain and PNS. As such, it is the pathway that leads sensory and motor signals towards and away from the brain. Other function includes spinal locomotion, the production of innate muscular behavioral ...
the body of each vertebra; this is theposterior longitudinal ligament. It also runs all the way down the spinal column. These spinal ligaments reinforce the stability of the spinal column, resist excessive flexion and extension of spinal segments, and protect the spinal cord from compression ...
