What is found in the periphery of spinal cord?
In cross-section, the peripheral region of the cord contains neuronal white matter tracts containing sensory and motor axons. Internal to this peripheral region is the grey matter, which contains the nerve cell bodies arranged in the three grey columns that give the region its butterfly-shape.
What is found in periphery?
The thick wall of spinal cord consists of an inner zone of grey matter and a peripheral zone of white matter.

What tracts are found in the gray matter of the spinal cord?
The grey matter of the spinal cord contains neuronal cell bodies, dendrites, axons, and nerve synapses.
In which part of the spinal cord are white matter and grey matter respectively found?
A transverse section of the adult spinal cord shows white matter in the periphery, gray matter inside, and a tiny central canal filled with CSF at its center.
Which spinal nerves affect which parts of the body?
The nerves of the cervical spine go to the upper chest and arms. The nerves in your thoracic spine go to your chest and abdomen. The nerves of the lumbar spine then reach to your legs, bowel, and bladder. These nerves coordinate and control all the body’s organs and parts, and let you control your muscles.
Where in the body are the peripheral nerves found?
Peripheral nerves reside outside your brain and spinal cord. They relay information between your brain and the rest of your body. The peripheral nervous system is divided into two main parts: Autonomic nervous system (ANS): Controls involuntary bodily functions and regulates glands.
Is gray matter good or bad?
The gray matter changes occurred in the hippocampus, the part of the brain believed to be central to memory. It is “a structure important for healthy cognition across people’s lifespan,” the study says, and is “centrally involved in many functions including spatial navigation, episodic memory and stress regulation.”
What is the difference between GREY and white matter?
What is the difference between grey and white matter in the brain? … The grey matter contains the cell bodies, dendrites and the axon terminals, where all synapses are. The white matter is made up of axons, which connect different parts of grey matter to each other.
What is the gray commissure of the spinal cord?
a bundle of nerve fibers that surrounds the central canal of the spinal cord and connects the anterior and dorsal horns of gray matter in each half of the cord.
