What is the function of white matter in the spinal cord? What is the function of the white matter in the spinal cord? What is the blood-csf barrier? Describe the formation of CSF. What is the function of the mucus membrane that lines the nasal cavities?
Understanding how the nervous system functions is critical as it enables the development of strategies for repairing the damaged nervous system. This chapter covers the major physical structures found in the central nervous system, including the brain and spinal cord, their properties, and their funct...
The term for nerves that conduct commands from the spinal cord to muscles and organs is efferent. The afferent and efferent nerves are associated with an H-shaped area of gray matter in the center of the spinal cord. The gray matter is separated into dorsal and ventral horns. The ventral...
They originate from the posterior horns of gray matter and exit through the posterolateral sulcus of the spinal cord. The anterior and posterior roots merge just before the intervertebral foramen, and form the trunk of the spinal nerve. The trunk is very short, and soon after exiting the ...
In addition, a summary table will present the key features of the laminae of the spinal cord. It will enable the reader to quickly access information related to the input and output of each of Rexed's 10 laminae in the gray matter, including a summary of the main functions of each of ...
The cerebral cortex is a highly convoluted gray matter structure consisting of many gyri and sulci. The lobes of the cerebrum are actually divisions of the cerebral cortex based on the locations of the major gyri and sulci. The cerebral cortex is divided into six lobes: the frontal, temporal...
He demonstrated the complexity of the central gray matter of the spinal cord, describing the "substantia gelatinosa," and he deduced that nervous structures are connected in a network of nervous fibers linked by electrical impulses. Rolando had to struggle for recognition, however, as the priority...
According to Framingham Heart Study data, 1 in 5 women over the age of 55 will experience a stroke in their lifetime [1,2]. Further, it has been established that females experience more severe strokes and have a greater functional impairment and higher mortality rate than males [2,3,4,5...
Thethalamus, or the dorsal and ventral thalamus collectively, are two oval structures made up of gray matter at the base of the cerebrum. This structure’s primary function is as a relay center through which sensory nerves transmit signals from the spinal cord and brainstem on the way to the...
The cell bodies of the posterior root neurons are not located in the central grey matter in the spinal cord, but instead in a structure called the spinal/dorsal root ganglion. The anterior and posterior roots join to form the spinal nerve proper, containing a mixture of sensory, motor, and...
