What is found in the periphery of spinal cord grey matter myelinated nerve white matter notochord?
Complete Answer: – We know that within the cross-section the peripheral region of the spinal cord contains neuronal white matter which refers to areas of the central nervous system that are mainly made from myelinated axons which also are called as tracts, it’s a passive tissue.
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.
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.
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.

|Which of the following is INCORRECT about the numbers of spinal nerves?||7 pairs of cervical spinal nerves|
|Which of the following parts of a spinal nerve carries sensory information only?||posterior (dorsal) root|

What is cord syndrome?
Central cord syndrome (CCS) is an incomplete traumatic injury to the cervical spinal cord – the portion of the spinal cord that runs through the bones of the neck. This injury results in weakness in the arms more so than the legs.
What are the 6 major tracts of the spinal cord?
We have plotted the position of six descending tracts (corticospinal, rubrospinal, medial and lateral vestibulospinal, rostral and caudal reticulospinal) and eight ascending tracts (gracile; cuneate; postsynaptic dorsal columns; dorsolateral, lateral, and anterior spinothalamic; dorsal and ventral spinocerebellar) on …
What happens if your spinal cord hurts?
Emergency signs and symptoms of a spinal cord injury after an accident include: Extreme back pain or pressure in your neck, head or back. Weakness, incoordination or paralysis in any part of your body. Numbness, tingling or loss of sensation in your hands, fingers, feet or toes.
