If the ventral root of a spinal nerve were cut, what would be the result in the tissue or region that nerve supplies?
a. a complete loss of voluntary movement
b. complete loss of sensation
c. loss of neither sensation nor movement but only of autonomic control
d. a complete loss of sensation and movement

Respuesta :

Answer:

a. a complete loss of voluntary movement

Explanation:

Spinal nerves serve as the paths of communication between the spinal cord and specific regions of the body. Roots refer to the bundles of axons that serve to connect each spinal nerve to a segment of the spinal cord via smaller bundles of axons called rootlets. The ventral root also called the anterior root and the associated rootlets contain axons of motor neurons.

These motor neurons of ventral root conduct nerve impulses from the CNS to effector organs. Muscles and glands are the effector organs. As these effector organs receive motor information, voluntary movements are generated. If the ventral root of the spinal nerve were cut, the effector organs will not get the motor information and no voluntary movements will be generated.

The study of the nerve cell is called nervous tissue. The nerve cell is made up of cyton, dendrite, axon, and synaptic ending.

The correct answer is A which is a complete loss of voluntary movement

What is voluntary muscle?

  • Those actions which you can control is called voluntary muscle. For example - moving of hand.

Spinal nerves serve as the paths of communication between the spinal cord and specific regions of the body. Roots refer to the bundles of axons that serve to connect each spinal nerve to a segment of the spinal cord via smaller bundles of axons called root lets.

The ventral root also called the anterior root and the associated rootlets contain axons of motor neurons. These motor neurons of the ventral root conduct nerve impulses from the Central Nervous System to effector organs. Muscles and glands are the effector organs. As these effector organs receive motor information, voluntary movements are generated.

If the ventral root of the spinal nerve were cut, the effector organs will not get the motor information and no voluntary movements will be generated.

Hence, the correct answer is option A.
