Where do the axons that enter the cortico-spinal tract originate? (The complete answer should include more than one of Brodmann’

torisob [31]

Answer:

From the main motor cortex, Brodmann region 4 premotor areas and the primary somatosensory cortex .

Explanation:

The corticospinal tract originates in many regions of the brain, including

the motor regions,
main somatosensory cortex
pre-motor regions

The corticospinal tract allows for voluntary control of motor functions.

30% of the neurons in the corticospinal regions are found in the primary motor cortex. 40% are split up in several regions; the parietal lobe, somatosensory cortex and the cingulate gyrus.

The axon is a tube enclosed in and insulated by the myelin sheath. It serves as a link to impulses for certain neurons that often comprise axon hillocks that are junctions between the axon and the cell body.

Which of these best describes genetic drift? A) The movement of alleles between population B) Random fluctuations in the gene fr

exis [7]

The correct answer is B.
Genetic drift is one of the four evolutionary mechanisms. It changes the frequency by chance, aka at random.
For example. if you have 100 frogs in the population, 20 red, 20 green and 60 yellow, not all of the alleles are going to be passed down to the next generation because a portion of the population can be affected by a random event such as the flood. So, if the flood accidentally kills 20 red frogs, none of the offspring are going to be red by chance.
