The medial pathway, which controls gross movements of the head, trunk, and limbs, consists of tectospinal, reticulospinal and vestibulospinal tracts.
The tectospinal tract in humans, also known as colliculospinal tract, is a nerve tract that coordinates head and eye movements. This tract is a part of the extrapyrimidal system in which it particularly connects the midbrain tectim and cervical regions of the spinal cord.
The vestibulospinal tract is a neural tract found in the central nervous system. It is specifically also a component of the extrapyramidal system and is a classified component of the medial pathway. The vestibulospinal fibers of the tract relay information from the nuclei to the motor neurons which is the same with the other descending motor pathways.
Lastly, the reticulospinal tracts or the descending or anterior reticulospinal tracts are extrapyrimidal motor tracts that goes down from the reticular formation in two tracts to act on the motor neurons supplying the trunk and the flexors and extensors of the proximal limb.
Answer:
Crossing-over occurs during meiosis
Explanation:
Mendel's principles never mentioned directly how the factors seperate, just that it happened during gamate formation, but nothing about how crossing-over occurs during meiosis.
<span>During the final days of her life, Celeste will likely be in more much pain, and it will be more difficult to control. She will likely not be able to move around on her own, or even speak. She will have difficulty swallowing, and may not be able to eat. Celeste will need help with basically all of her self-care, and activities of daily living.</span>
Answer:
it was 27x larger in 1982
Explanation:
The cod fish population has dropped in New England between 1982 until today due to higher mortality rate. The population of cod fish in1982 is 80000 metric ton of spawning stock biomass while on the other hand, the population of cod fish in 2011 is 2500 metric ton of spawning stock biomass. This lowering of cod fish population is due to higher mortality rate so we can say that the population of cod fish was 27x larger in 1982.
