1/8 Synonyms: none As the overseer of the majority of the body's physiological processes, the brain has numerous connections with extracranial structures. The spinal cord acts as one of the primary conduits through which the body and the brain exchanges information. The spinal cord is the caudal continuation of the brainstem.

Figure 12.6. 6: Spinal Nerve. The ventral and dorsal nerve roots exiting a cross section of spinal cord fuse together to form a spinal nerve, which then splits into the dorsal and ventral rami. The white and gray ramus form the rami communicantes that connect spinal nerves to autonomic ganglia.

Last update: Oct 24th, 2022 Learn anatomy faster and remember everything you learn Start Now The spinal cordis made up of 31 segments. Each segment gives rise to a pair of spinal nerves. 1 2 In cross-section (c.s.), the segments appear to be divided into two zones. The outer zone contains many myelinated axonsthat run up and down the spinal cord.

The spinal cord, when viewed in cross section, is composed of central gray matter and peripheral white matter. The gray matter resembles a butterfly in shape and may be subdivided into three pairs of horns: dorsal, lateral (found only between the first thoracic and second lumbar spinal levels), and ventral. Sensory neurons enter the spinal cord.

The vertebral column (spine or backbone) is a curved structure composed of bony vertebrae that are interconnected by cartilaginous intervertebral discs.It is part of the axial skeleton and extends from the base of the skull to the tip of the coccyx.The spinal cord runs through its center. The vertebral column is divided into five regions and consists of 33 vertebrae interlaced by strong joints.

A cross-section through the spinal cord is illustrated schematically in Figure 2.6 and 3.4. The gray matter forms the interior of the spinal cord; it is surrounded on all sides by the white matter. The white matter is subdivided into dorsal (or posterior), lateral, and ventral (or anterior) columns.

The spinal cord is part of the central nervous system and consists of a tightly packed column of nerve tissue that extends downwards from the brainstem through the central column of the spine. It is a relatively small bundle of tissue (weighing 35g and just about 1cm in diameter) but is crucial in facilitating our daily activities.. The spinal cord carries nerve signals from the brain to other.

the structure of the brain and its functions
The spinal cord is a thick cable of nervous tissue extending from the medulla oblongata of the brain stem to the neck and torso. Viewed in a cross-section, it has a roughly oblong shape with white matter on its exterior and a butterfly-shaped region of gray matter on its interior. A small, circular tube-like cavity known as the central canal.
