What is the bridge of the gray matter connecting the right and left horns of the spinal cord?
Gray commissure
What are the outward projections from the central gray matter of the spinal cord called?
horns
What part of matter include the dorsal and ventral horns of the spinal cord?
grey matter
The projections of gray matter toward the outer surface of the spinal cord are called?
Horns
What are the six projections from the gray matter seen in cross-sections of the spinal cord called?
horns
What is the Gray matter that resembles the upper wings of a butterfly in spinal cord cross section?
Posterior Horns.
What part of the spinal cord contains lateral horns?
posterior part
The gray horns of the spinal cord contain?
posterior part
What type of impulses enter and leave from opposite sides of the spinal cord?
Afferent impulses enter the spinal cord from the posterior section. They may get processed by interneurons. And, in most cases they exit the spinal cord through the efferent neurons in the anterior section. The reason that they refer to this as being opposite sides has to do with what are called the 'horns' inside the spinal cord. The afferent impulses enter the dorsal horns in the back and the efferent impulses exit in the front, the anterior horns. This may be why your reference, your teacher, or a book, says that impulses enter and leave from opposite sides of the spinal cord.
How does the arrangement of white matter and gray matter differ in the spinal cord and the brain?
Gray matter in the cerebrum is located in the cerebral cortex and in the deeper basal nuclei, and the white matter lies deep to the neural cortex and around the basal nuclei (Fundamentals of Anatomy and Physiology, Martini & Nath, 2009, p. 480).The central area of the spinal cord is gray matter, and the outer surface of much of the brain consist of gray matter called cortex. (Anatomy and Physiology, Seeley Stephens Tate, 2008, p. 382)
Where is the Cell body of the motor neuron?
In the grey matter of the central nervous system anterior gray horns
Distinguish between the dorsal and ventral horn?
The tips of the anterior horns are broader and less tapered than those of the posterior horns. Human Anatomy & Physiology Laboratory Manual Ninth Edition Elaine N. Marieb & Susan J. Mitchell
