Answer:
A patient with a spinal cord injury that resulted in paralysis of the legs has paraplegia (option c).
Explanation:
Paraplegia consists of paralysis of the lower extremities or legs due to injuries to the spinal cord, from the dorsal vertebrae. Other causes of paraplegia include tumors and malformations that affect the spinal cord.
<u>The spinal cord provides the nerves that allow the innervation of the limbs</u>. A spinal cord injury interrupts communication between the brain and the effector (motor) muscles as well as the sensory nerves in the affected limbs, producing paralysis. When it occurs in the legs is called paraplegia.
The other options are not correct because:
a. Hemiplegia corresponds to paralysis of upper and lower limbs on one side only.
b. Pseudoplegia is a paralysis that is due to mental disorders such as conversion disorder, without injury to the nervous system.
d. Dysplegia is associated with motor disorders observed in children with varying degrees of dysfunction or cerebral paralysis.
When the skin is exposed to ultraviolet rays, the skin produces a molecule that is turned into Vitamin D.
Sun is the source of ultraviolet rays important for Vitamin D production. Due to this reason, in the case of Vitamin D deficiency, it is recommended by doctor's to absorb sunlight by skin. The Vitamin D production occurs specifically by UV B rays rays which lie in the range of 290-315 nanometer.
The chemical 7-dehydrocholesterol absorbs these rays and convert to previtamin D3. Further, previtamin D3 isomerizes to Vitamin D. Other than sunlight, Vitamin D can be taken through diet. The sources include seafood like fish, fish oil, dairy products, beef liver etc. Vitamin D is required for bone and teeth formation, muscle contraction, immune system etc.
