What else can I help you with?
What are the outward projections from the central gray matter of the spinal cord called?
horns
What are the six projections from the gray matter seen in cross-sections of the spinal cord called?
horns
What are areas of grey matter in the spinal cord called?
Cartilage
Where does the spinal cord have gray matter?
The grey matter on a spinal cord is on the spinal roots.
The tough outer membrane of the spinal cord is called?
Dural sheath or dura matter
Is the inner surface of the skull lined with dura mater or pia mater?
The inner surface of the skull is lined with dura mater, which is the tough outermost layer of the three meninges that surround the brain and spinal cord. The pia mater is the innermost layer that is directly attached to the surface of the brain and spinal cord.
Where is the white matter located in relation to the gray matter in the spinal cord?
The white matter is located on the outside of the gray matter in the spinal cord.
What is the tissue of the brain and spinal cord containing nerve cell bodies?
It is still nerve tissue but it is what is called grey matter
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 white matter located within the spinal cord?
The white matter is located on the outer part of the spinal cord.
Is the spinal tract composed of grey matter?
The spinal tract is primarily composed of white matter, not grey matter. White matter consists of myelinated axons that form ascending and descending pathways for nerve signals. In contrast, grey matter, which contains neuronal cell bodies, is found in the central region of the spinal cord and is organized into horns. Thus, while grey matter is present in the spinal cord, the spinal tract itself is predominantly white matter.
Where are the spinal reflex centers located?
In the gray matter of the spinal cord.
