epididymis-vas deferens-urethra
Answer:
<u>From the main motor cortex, Brodmann region 4 premotor areas and the primary somatosensory cortex .</u>
<u />
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.
A population decrease in primary producers would affect the ecosystem negatively because everyone who ate the primary consumers would have a lack of food.
Answer:
decrease in population of the prey and an increase in rabbit population
Explanation:
The prey were constantly being killed and eaten by rabbits so there was a decrease in their population whilst the rabbits had an increase in their population due to there being more food for the to live on and there being less competition.
