Destruction of the anterior horn cells of the spinal cord would result in loss of
A. Sensory impulses
B. Voluntary motor impulses
C. Commissural impulses
D. Integrating impulses
Solution
Spinal cord consists of grey matter and white matter, grey matter constitutes 70% in making the spinal cord, this matter has three projections which are referred to as horns. The grey matter of the spinal cord has motor nerves responsible for movement impulses generated by the body.
Complete answer:
The spinal cord comprises three projections called "horns." The horn is additionally partitioned into fragments (or segments) with the dorsal horn arranged to the back, the horizontal horns put to the sides, and the front horn found forthright.
Skeletal muscle development is only one of the capacities controlled by the peripheral sensory system.
The nerve cells answerable for handing-off these messages are called motor neurons.
A disease occurring in the grey area and specifically in horns causes muscle tone which will affect the normal movements as reflexes and signals will not be delivered on time
Lower spinal cord disease will affect the spinal cord cell bodies which will affect muscular atrophy.
Spontaneous contractions will be occurring in a condition fasciculations
The correct answer is an option (b) which is voluntary motor impulses.
Note:
There are many diseases caused by the motor neuron defection few are:
ALS is known as Lou Gehrig disease, the most common disease, it affects muscle movements of the arms, legs, respiratory system. This disease is inherited from the parent (family genetics)
PBP as progressive bulbar palsy involves the brain stem cells affecting in speaking reflexes such as difficulty in speaking, choking spells, eating difficulty.
