The term used to describe a main nerve trunk as it arises from the spinal canal. It soon divides into a number of branches, some of which join with other nerve roots and go on to supply various parts of the body including muscle groups (myotomes) and specific areas of skin (dermatomes).
where the main nerves of the body leave the spinal cord and pass out of the spinal canal through the intervertebral foramen, where they then feed through the body either anteriorly (motor nerves) or posteriorly (sensory nerves). The anterior divisions supply the front of the spine including the limbs. The posterior divisions are distributed to the muscles behind the spine.
This is the portion of the nerve that comes off of the spinal cord and exits the vertebral canal (spinal canal) through a root foramen or hole in the bone.
The exit of the nerves from the spinal cord.
The start of the nerve as it leaves the spinal cord of cauda equina and passes through the left and right foramen to serve an area of the body.
A bundle of the motor and sensory branches which join to form a spinal nerve which exits the spinal cord through a bony opening called the intervertebral foramen. Two nerves leave at each spinal motion segment, one on the right and one on the left.
The portion of a spinal nerve in close proximity to its origin from the spinal cord.
One of the two nerve bundles emerging from the spinal cord that join to form a segmental spinal
The end of a spinal nerve nearest its attachment to the spinal cord.
name given to nerves as they exit the spinal canal
A sheaf of nerve fibres entering and leaving a segment of the spinal cord.
The portion of a nerve adjacent to the CNS centers of the brain and spinal cord that they innervate. image
